Website Relationships – Political Edition

With the new Relationships feature of BuiltWith now available we thought we’d take a look at two websites to show you the sort of knowledge you can gain from this new feature.

We’ve taken and as the two websites we’ve going to analyse.

Tag Relationships

Hillary only has a Google Analytics ID that we have currently tracked for the past 5 years –


We’ve tracked since 2011 and it’s consistently used the same UA account since then.  You can even see Hillary’s 2008 campaign domains using it for a while back in 2012 for some reason.

Copying a Website

There are a few strange ones in there, namely and – the first site is of an Iranian doctor and the second is a very strange political related landing page (not related to Clinton) – these sites have ‘lifted’ code at some stage from Hillary’s website.

This provides the ability to use the Relationship dataset to see if websites have copied code down to an analytics level.

IP Address Changes


Hillary’s website has been on Amazon’s network for quite some time and has probably been using their edge content delivery network as you can see by the wildly differentiating IP addresses in use on a week to week basis as well as on an overlapping basis.

The site was on up until 2015, which is a Rackspace owned server – clicking through to it shows it was used by a few other political related websites between 2013 and 2015 including – a US senator –


It was most recently used by Palo Alto based CPA firm Sorensen and Holland but now redirects to a parked domain page.

Tag Relationships


We’ve only started to cover on BuiltWith since mid-2015 – we have coverage for and going back to early 2011.

Web Agency Discovery

Looking at the related tag history for a few things stand out – and are both using the same Facebook Tracking Pixel. These are both Texas based businesses and a quick look at those sites identify them as being designed by Giles-Parscale. A quick Google shows that Giles-Parscale built the website however the link isn’t always that easy to find. The relationships BuiltWith tool can help to discover this information.

Data Leaks and are two satirical websites which have lifted the design of – however they have also leaked visitor information back to Trump’s campaign by leaving in Google Analytics and Facebook Pixel ID of the original site in their code.

IP Address Changes


Trump’s website has been using Cloudflare since we’ve been tracking it – it appears it was on a lower price point version of the software up until September 2015 when it appears to have moved to a more premium plan as its IP addresses appear to be dedicated to the website.

You can use this information to determine the security of a website – does it have a shared plan, is it on shared hosting, when did it move to a more premium system.



This is just some of the information you can garner using the BuiltWith Relationship tool on BuiltWith – just go to and enter a domain name and click the relationships tab to start exploring this data yourself. You can also automate this data into your own application or data set via the Relationships API.

Website Relationship Tracking

We’ve just added a whole new bulk of functionality to BuiltWith – we’ve been tracking website technologies for years. Many of these technologies give off a customer ID of some sort.

The most well known and most used is the Google Analytics ID, which is basically in the format UA-XXXXX-YY, where the XXXXX section is normally assigned to a single login and the YY is an incremental integer for the different web properties login XXXXX owns. Tracking the entire internet, we can link all of these together and use our huge historical archive to back-track data to 2010.

We track this, IP addresses and hundreds of other technology attributes and provide it all in a historically accessible manner and all totally for free.


Use cases for this include –

  • Finding security gaps  – are they on shared hosting – what websites are customer analytics data shared with
  • Finding a business’ clients – web agencies might share analytics, IP address space with their customers
  • Finding side/failed/main projects – see what businesses a website tried before their current one
  • Find acquisitions of other businesses

Pro users can mass export domain relationships and technology tag data from BuiltWith Pro and anyone wanting to access this data in an automated manner can use the new Relationships API.

We’ll be publishing some interesting relationship data on the blog soon so come back and check it out!


More Data for Free Users

Free users of BuiltWith can now create 5x as much data in free BuiltWith Pro reports (raising from 20 to 100 results). This provides a level of usability to the tool for free users as well as providing more data to play with if you’re considering upgrading your account.


We called our free account ‘Trial’ but now we’re calling it ‘Free’ to support what we believe is a useful tool for both non-paying and paying customers of BuiltWith.
