The Top 5 Most Popular eCommerce Platforms

In my last post, I began running through the top 10 most popular eCommerce platforms in use on the web today. In that post I started in tenth position, and covered all of the technologies in the bottom half of the list. In this post today, I’m going to resume the countdown and move from fifth to first, revealing the most prolific eCommerce technology online today.

To compile this list and to find out which websites are using each platform I’m digging into just some of the BuiltWith data. Feel free to have a look at the data for yourself, which covers much more than just the eCommerce platforms being presented here. For some of my research I’ve tapped into data available through BuiltWith Pro, which is even more revealing. You can find out more about that here.

So, without further ado, let’s pick up where we left off last time with the eCommerce platform in fifth position.


5 – osCommerce

osCommerce is one of the most popular open source shopping carts available online (although not the most popular, as we’ll see later). Built by a team of self professed geeks, this popular eCommerce platform has been running for over 12 years. In that time, hundreds of thousands of online stores have been created and various other products (including one that will feature further down in this list) have been based on the software.

The platform has enough features enabled by default for it to provide a complete “out of the box” solution, but osCommerce can also be enhanced and has a huge number of add-ons available. osCommerce is well regarded for being simple to implement for users setting up a fairly basic shopping cart, although it’s perhaps a little more difficult to modify the design and appearance of the cart than some of the other available platforms.

The image below shows osCommerce in action. It shouldn’t come as a surprise that Ubuntu would implement an open source eCommerce platform, and sure enough, they’ve gone for osCommerce.

4 – WooCommerce

Next up is WooCommerce. This platform has been built specifically for WordPress users and promises to “transform your WordPress website into a thorough-bred ecommerce store for free.” WooCommerce is widely praised for being easy to use by store owners and customers alike. True to form for a WordPress based application, there are loads of themes to choose from to customize the look and feel of the store front.

Whilst the basic WooCommerce package is free, and really can be used straight “out of the box”, there are additional extensions which can be bought to add extra functionality. It’s likely that in many cases, the basic shipping options and few payment options aren’t enough and at least some of the extensions would make a worthwhile purchase.

Looking at the BuiltWith trends data for WooCommerce, this platform has to be one of the fastest growing eCommerce platforms out there. The number of websites in the top million sites using WooCommerce has roughly doubled in the last six months.

The image below shows WooCommerce put to good use on the sewing blog and store Sew Mama Sew.

3 – Magento

In the bronze medal position is Magento, the eBay owned eCommerce platform. Magento comes in three different flavours, two of which are paid versions tailored towards either small or mid-large size businesses and the third is a free open source Community Edition. Perhaps more well suited to larger stores, Magento is a powerful platform with a strong reputation.

Looking at the trends data for Magento, this is another technology that’s becoming more and more popular. Magento is slowly but surely closing in on the top two spots.

Magento is being implemented by all kinds of stores all over the web. Perhaps the biggest brand using Magento is Walmart, who are using Magento to power their liquidation auctions store as you can see in the image below.

Walmart Liquidations


2 – Zen Cart

It’s getting serious now, we’re into the top 2. The second most popular eCommerce platform on the web today is Zen Cart.  Yet another open source software package, the heritage of Zen Cart is the same as osCommerce discussed above in fifth position. The Zen Cart development line split from osCommerce back in 2003 when new architectural changes were made to the code, although the two platforms still share a range of features. As with most open source software, Zen Cart is distributed under a GNU General Public License, which means it’s free for anyone to use, change or modify.

Whilst powerful and popular, Zen Cart is another platform packed with features that might be intimidating to someone looking to quickly set up a simple eCommerce store. Having said that, there is a range of different training materials and support out there.

In the image below you can see Zen Cart in full flow on lightinthebox.com.



1 – VirtueMart

The most popular eCommerce platform on the web today is VirtueMart. It probably shouldn’t come as a surprise that this is yet another open source platform. VirtueMart is an eCommerce platform build on the Joomla! content management system (meaning Joomla! must also be used on any eCommerce store using VirtueMart).

Whilst VirtueMart is free to use, there are a whole load of additional extensions that can be bought to enhance the look, feel or functionality of a a store. The platform has a good reputation and has enough features for most stores without needing to change too much.

However, not everyone is convinced by the power of VirtueMart. As you’d expect from an open source platform, the support isn’t at the same level as you’d want from a paid-for package. WooCommerce (currently sitting in fourth position) released a case study earlier this year explaining why one of their users had moved from VirtueMart to their platform. In there they mentioned support as one of their biggest gripes (although you could argue that there isn’t much incentive for the case study to present VirtueMart in a totally balanced light).

The quality of VirtueMart stores is quite low, it could be considered an e-commerce relic with many newer solutions offering easier to integrate functionality. It’s growth doesn’t match some of the competing products though, so it may only be a matter of time before it’s knocked off the top spot. To see it in action, VirtueMart provides the backbone for the store on dominoes.com, a board game store.



Wrapping Up

So there you have it, the top ten most popular eCommerce platforms on the web today. If you’d like to get your hands on detailed, customized reports on all of these eCommerce technologies and more, BuiltWith Pro might be for you. Have a look at what’s on offer with a Pro account here.

Global eCommerce Sales Trends

Today we’re pleased to launch a whole new section of BuiltWith called BuiltWith eCommerce. We are now providing global eCommerce volume and sales trends as well as access to lists of eCommerce stores from over 1.7 million eCommerce categorized businesses.

Our volume and sales trends data is sourced from over 100,000 participating online shopping stores and for the first time ever, lets you see and track international eCommerce volume.

This chart shows relative global shopping volume change across multiple ecommerce regions.

This chart shows relative global shopping volume change across multiple ecommerce regions between October and November 2013

Basic and Pro customers of BuiltWith can download lists of eCommerce categorized websites, as well as apply the same analysis functionality that BuiltWith provides for technology based lists. So for example, you could generate a list of all clothing stores in the US and then create a sub-list of all of the Magento stores in this list, or all of the stores using a premium EV SSL certificate.

The Most Popular Ecommerce Platforms On The Web

Over recent years the internet has made it easier for producers and suppliers to reach new and existing customers with their products. This is the age of the online store. Because of this massive opportunity, there are a whole host of platforms competing to provide the foundations of the online stores we all know and love.

I’ve been having a look through the BuiltWith data on ecommerce technologies (of which there is a lot!) and thought it’d be interesting to highlight the top 10 ecommerce platforms in use on the web today. This is most definitely a congested market, with lots of companies all vying to provide the backbone of online stores, big and small, around the world. Using the BuiltWith data, I’ll pick out one or two examples of the stores that use each technology so we can see each of the ecommerce platforms in action. Over this post and the next I’m going to run through the top ten most popular ecommerce platforms.

Today, let’s look at the technology sitting in the bottom half of the top 10 list.


10 – Etsy

In the number ten spot is Etsy. More commonly known as a website in it’s own right, than an ecommerce technology used around the web, Etsy is a platform which allows users to set up stores to sell their handmade and vintage goods. Etsy has grown and grown over the last few years and their home page receives over 1.5 billion page views each month. The reason Etsy is appearing in this list though, is because Etsy offer their store owners a widget that can be embedded into their own web pages. There are over 800,000 store owners on Etsy (that was a year ago, and it’s definitely grown since then) so there are a lot of potential users of their shopping widget. Integrating the widget on your page won’t give you the freedom of most of the other ecommerce platforms but it’s a simple, quick and easy way to start selling straight away (as long as you want to sell items that fall within those allowed by Etsy).

Frugally Sustainable is an example of one of the bigger sites using the Etsy plugin. As you can see from the image below, this sustainability blog is using the plugin to sell handmade herbal and natural goodies.

9 – UberCart

Next up is Ubercart. This open source ecommerce package fully integrates an online store front with Drupal and has been designed to allow developers to add or alter Ubercart features to fit in with virtually any ecommerce need. Ubercart boasts that it’s the most popular Drupal ecommerce platform and supports the sale of physical products, digital downloads and also subscription based billing. Despite it’s strong features, Ubercart has a bit of a reputation for being quite difficult to set up and work with. A lack of documentation is identified by some as Ubercart’s biggest problem, which is a shame since it’s clearly a powerful ecommerce solution when it’s up and running.

In the image below Ubercart is put to good use on Almanac.com, the online home of North America’s oldest continuously published periodical.



8 – BigCommerce

In eighth position is Big Commerce. This shopping cart has been growing steadily for years now and seems to be continuing the trend. Packed with features, this platform has built quite a reputation for being highly customizable and user friendly.

BigCommerce has several pricing options which means that, to the annoyance of some, one or two of the most prized features are not included with the cheaper packages. It’s hardly a surprise that this solid platform would upsell to it’s users with the promise of even more useful features though. Any ecommerce platform worth it’s salt should be doing just that. It’s clear that this popular shopping cart is doing things right, and its number of users is growing month on month.

One of the bigger sites using Big Commerce is PetaPixel, the popular photography blog. In the image below you can see Big Commerce fully integrated with the site, offering an attractive store front.




ECShop is another open source ecommerce platform. Whilst quite popular with sites from across the entire web, the use of ECShop is all but non existent on bigger websites. Written in Chinese and with a unknown reputation outside of Asia, there are probably more suitable ecommerce platforms out there for readers of this post.

Nevertheless, here is ECShop in action on runsky.com.



6 – Shopify

Shopify is in sixth position. This ecommerce platform is looking to be the one stop shop for anyone wanting to set up an ecommerce store. Shopify make their position quite clear on their website where they offer “All the features you want, none of the clutter. Shopify handles all the hassles of online retail.”

Powering over 60,000 stores, Shopify has really accelerated it’s growth since 2011 and the trend doesn’t look like it’s slowing down. It’s user-friendly interface with plenty of templates has been crafted to be used by merchants themselves instead of developers or designers. Shopify has a good reputation and is especially well regarded by people who have used it to set up new online stores.

Shopify powers the ecommerce parts of quite a few popular sites including InstructablesBritannica and National Review. It’s clearly a powerful solution, and is the preferred platform of many ecomerce store holders. In the image below, you can see Shopify in action on yet another popular site: Github.



Wrapping Up

So that brings us to the half way point in the list of the top 10 most popular ecommerce platforms on the web today. If you’d like a sneak preview of the technologies I’ll be looking at next time, check out the BuiltWith Trends data. In my next post I’ll be breaking into the top 5 and looking at the really big players in the ecommerce technology market.

If you’d like to get your hands on detailed, customized reports on all of these ecommerce technologies and more, BuiltWith Pro might be for you. Have a look at what’s on offer with a Pro account here.

Introducing Competitor Comparison

Competitor comparison is a new customer acquisition tool in BuiltWith Pro that lets you compare technologies on a week to week basis back to January 2011.

Access competitor comparison on your Pro dashboard by selecting the “create new report” button.

What does it let me do?

  • See which websites are moving between competitors on a weekly basis
  • See who is trialing a competitor product
  • See which technologies are increasing their global market share quicker than others

But that’s not all, the competitor comparison system is broken down into separate parts, which includes an overview section which provides an idea of how many active websites we are tracking in total for the group of technologies you have selected -

Active website for technologies in our live system.

Active websites for technologies in our live system.

This gives you an idea of how many websites a group of competitors have as a total of the entire market share. One of the use cases of this is determining if a technology is growing at a slower rate than the market itself.

The customer movement trends tab shows the amount of websites that made full switches between the competitors, as in, they stopped using one technology and started using another one.

Net gain or loss to competitors over time.

Net gain or loss to competitors over time.

This chart can be used to determine which competitors are taking your customers away.

The customer movement lists tab shows the actual websites that are moving between the groups. This lets you create a live view of where customers are moving between and with one click of the create report button you can get the full report on technology movement between technology providers. You can also create crossover technologies (i.e. websites trialing other providers) by modifying the technology start and end dates on the report once it is created.

A Closer Look At Popular WordPress Plugins

We’ve already seen that WordPress is the most popular content management system (CMS) on the web today. WordPress is being used by around three times as many of the top 100K sites than it’s closest competitor, Drupal. One of the reasons for its success is the amount of customization that’s possible.

The WordPress CMS can be used for a whole host of different applications, whether you’re looking to set up a blog, a portfolio site, an ecommerce store, a membership site or anything else, there is a way to do it with WordPress. The main way that WordPress incorporates all of these different functions is by using plugins. The WordPress plugins allow a site owner to pick and choose which functionality to add, and to customize their site.

There are currently over 25,000 WordPress plugins to choose from, many of which claim to do the same job as countless other plugins out there. So how do you know which plugins to choose?

One place to start would be with articles describing which are the best plugins of each type, but perhaps an even better place would be to dive into the data to see what story it tells.

In the sections below I’ll focus on three popular WordPress plugins and see what the BuiltWith Trends data is telling us.

W3 Total Cache

W3 Total Cache is a plugin which aims to improve the user experience of a site by caching aspects of a site and reducing user download times. It has been around for a while and has proven to be quite popular with a good number of WordPress users. Looking at the general trend data, it would appear that the uptake of the W3 Total Cache plugin is holding steady in its usage.

Websites using W3 Total Cache in Top 10k, 100k and Million

Websites using W3 Total Cache in Top 10k, 100k and Million

However, this data doesn’t tell the full story.

The W3 Total Cache plugin is a WordPress plugin, and will only ever be found on a WordPress site. The chart above shows that 10,000+ of the top Million of all sites use the plugin, whether WordPress is their CMS or not. Whilst the general trend on this chart is moving up, it doesn’t necessarily mean that the W3 Total Cache Plugin is getting more popular. The trend could also be explained by there being more WordPress sites in the top million sites. To work out what’s really going on, we need to take a look at the percentage of WordPress sites which use the W3 Total Cache plugin. Doing that gives some interesting results.

Here we can see that the plugin is actually becoming less popular rather than more as it first appeared. It’s interesting to note that the plugin has a higher uptake amongst the WordPress sites found in the top 10k sites, with just under a third using the plugin towards the end of last year. Since these sites are more likely to be well optimized, it looks like the plugin was considered to be very effective. The trend started to tail off at the start of this year, especially amongst the WordPress sites found in the top 10k. Looking at the data, it seems likely that something else was released at the end of 2012 that WordPress sites started to use for caching.

Yoast Plugins

Next up are the Yoast plugins. Yoast offers a range of WordPress plugins and by far the most popular is their WordPress SEO plugin. This set of tools allows WordPress site owners to optimise their pages to boost their rankings in search engines.

Looking at the data in the same way as above, showing the percentage of WordPress sites using Yoast plugins, gives the following chart.

Percentage of WordPress sites using Yoast Plugins

Percentage of WordPress websites using Yoast Plugins

These trends look very healthy, and would be enough to persuade me to give the Yoast plugins a go. Since 2012, uptake of these plugins has continued to grow and a significant percentage of WordPress sites now use them. Notably, it’s been the WordPress sites found in the top 10k that have led the way from the beginning. This suggests that the plugins were effective from the start, and burst onto the scene with a bang. As word has spread, more and more people have started to use them.

Contact Form 7

Now for something a little bit different. Contact Form 7 is a popular plugin, but lesser known than the two above, that creates a custom contact form which can be embedded on a page of a WordPress site. Let’s dive straight into the data with the same view as before showing the percentage of WordPress sites using the plugin.

Percent of WordPress sites using Contact Form 7

Percentage of WordPress websites using Contact Form 7

The most interesting thing about this chart is that the percentage usage started off as the lowest amongst WordPress sites in the top 10k. This trend suggests that before September 2012 the plugin was quite immature and/or there was a better alternative. Since that date though, the usage of the plugin has grown most rapidly amongst WordPress sites in the top 10k. This suggests that confidence in Contact Form 7 is growing, especially amongst WordPress sites in the top 10k. This upward trend would make Contact Form 7 a strong contender if I were looking for a way of implementing a contact form on a WordPress site.


Quite often just looking into the data tells the real story about what’s working and what’s not. You don’t always have to rely on a strangers recommendation. With just a little bit of digging you can quite quickly find out all you need to know.

We’ve also recently added coverage for lots of WordPress plugins, theme and extensions which can be found under the WordPress Plugins category of widgets on BuiltWith Trends.

What Is Tag Management?

The tag management market is one that has seen quite a lot of disruption over the last year. The overall tag management market has been growing for a while now and is showing no signs of slowing down. Before we get too deep in the data, let’s take a step back to understand what tag management is and why it’s becoming increasingly popular.

In order to understand tag management, we first need to take a quick look at tags and how they’re used on the web. A tag is a snippet of JavaScript code embedded into a web page, usually in the body of a page. They’re used to send information about a page and it’s visitors to third party vendors who provide services such as the following (this is definitely not an exhaustive list):

Many of these services are focussed on allowing a web site owner to optimize their site for maximum conversions (in terms of sales or sign-ups or any other important metric). There are loads of different services which help to optimize sites, and many of them use tags to track their data.

As with all things in the online world, third party optimization services come and go. Switching to a different service, or adding a new service, can mean significant editing of the tags is required. In some cases the process can be cumbersome and frustratingly slow. Quite often, it’s difficult to keep track of all the tags used on each page of a website. And so, tag management services came on the scene to alleviate the problem.

The frustration associated with modifying tags is exaggerated in larger companies with bigger websites. In these cases, the implementation of a tag management system could reduce the turn around time for altering the tags on a page from weeks to minutes. Rather than going through the lengthy process of adding proposed changes to a work queue, going through meetings to explain and justify the modifications, a tag management system allows tags to be altered without needing to touch the underlying code. This simplifies the process and allows marketeers to make tweaks to the way their data is gathered without the risk of adversely affecting the rest of the website. As the team at Google say, a good tag management tool “puts you, the marketer, back in control of your digital marketing”. A decent tag management tool will mean you can update your tags without “bugging the IT folks” (thanks again to Google for that one).

Key Players

Until the end of 2012, the biggest players in the tag management market were BrightTag, Tealium and Ensighten. All three were pretty even in terms of market share and each had a slice of the pie for websites of all sizes. There were other tag management tools available but these three dwarfed the rest and between them, dominated the market. These three tools have been growing steadily for a while, and on the whole, continue to do so now. Their growth can certainly only be described as steady though, especially when compared with the explosive entry to the market of a new tag management tool from Google.

Tag Management Technology Usage on Top 100k Sites from June 2012 to August 2013

Google Tag Manager

Google Tag Manager is a tool which could seriously disrupt the status quo. It’s been making waves since it was launched last year, and has rapidly become the most popular tag management tool on the internet. Whereas most of the other tools available on the market are paid tools, Google Tag Manager is free. Just like in 2006 when Google launched Google Analytics, the power of free has the potential to really change the game.

Google Tag Manager was officially announced on October 1st 2012 on their analytics blog. The eagle eyed amongst you will notice that the usage chart for Google Tag Manager starts to rise before the official launch date at the start of October. Prior to the official announcement and release of Google Tag Manager, quite a few companies had already begun using the tool. In the first month, before the official release, Google invited a number of sites/companies to try the initial version of Google Tag Manager. From that time onwards, the tool has become more and more popular. After an initial burst which lasted a couple of months, the rate at which Google Tag Managers usage has grown decelerated slightly, but it still continues to grow month on month. It didn’t take long for the tool to overtake the rest of the field and grab the largest market share. By the start of 2013, Google Tag Manager was the most popular tag management tool even amongst the top 10K sites (a group which can sometimes be slower to transition to new tools).

It’s difficult to say when the upward trend will stop. It’s likely that Google Tag Manager will reach a usage ceiling at some point, where growth really slows down (similar to the way Google Analytics did a few years ago), but it shows no sign of slowing down yet. Google are continuing to add features which will enable Google Tag Manager to compete more directly with some of the other tools out there. If Google can keep upgrading their tool, it’s not unreasonable to assume that their growth will continue for a while yet.

Wrapping Up

The tag management market as a whole appears to be growing and, at the moment at least, there seems to be enough business to keep all of the major tool providers going. Google Tag Manager is by far the most popular tool, and it’s market share is increasing consistently month on month, especially amongst smaller sites. Most of the other tools also seem to be maintaining or adding to their user base, with the paid tools like Tealium attracting some pretty big sites. As time goes on, it seems quite likely that the usage of tag management tools will closely resemble the analytics market. However, this time, Google look set to take an even bigger slice of the pie.

For a closer look at the data behind these tag management tools, as well as a whole host of other technologies, head over to the BuiltWith Trends pages.

Liberal vs. Labour – Web Technology Showdown

Australia is set to vote next month in the 2013 federal election, we take a look at the two major parties homepages to determine who is winning from a web technology standpoint.

Liberal vs. Labour


Labour – alp.org.au

Community Organizing System – both a website and a people database. It’s a CMS system specifically designed with governments in mind, based out of Los Angeles, NationBuilder has raised over $14 million. The ALP previously used a Microsoft Kentico CMS before swapping that our for NationBuilder just 3 months ago.

Hosting - Amazon EC2 Singapore
The ALP website is hosted in Amazon infrastructure, based out of Singapore. They should consider using Amazon’s Sydney based infrastructure for faster response times for visitors to their site.

Analytics - ChartBeat, Google Analytics and New Relic
Some of these technologies may be installed by the CMS system in use. ChartBeat provides real time analytics for their website whilst New Relic monitors the hardware. Google Analytics is installed on the majority of websites as par for the course.

Email - Not known
All signup forms and records tell us they are using their own in-house mailing system. They may be using a package we cannot identify.

Liberal – liberal.org.au

CMS - Drupal
The liberals have been using Drupal for a year, before that they used SiteCore CMS. Interestingly both the liberal and labour party have moved away from Microsoft to use more open source based CMS systems.

Hosting - Amazon EC2 Sydney
The liberal’s site is hosted on Amazon infrastructure but based in Sydney. Their website response time from Sydney is 7 times faster than the ALPs because of this.

Analytics - Optimizely, Google Analytics
The liberal team are using A/B testing with Optimizely. Optimizely was created by developers on Obama’s initial election campaign website.

Email - Campaign Monitor / MailChimp
Slightly confusingly the liberal’s web presence shows signs of using both Campaign Monitor and MailChimp. If the Liberal’s are using Campaign Monitor then this is the only home-grown web technology currently in use on both parties websites.

The Winner

Australians in the tech space who want Australia to benefit from the National Broadband Network should consider voting for Labour, as the liberals have plans to scrap it. However, based on the website implementations, the liberal party has more of a technical edge in their implementation. They’ve used Australian based hosting (albeit via a US company) as well as a Sydney based company to provide them with mail campaign support and are using some more advanced caching technology such as Varnish to ensure their website can handle significant load.
