Premium Sites Index

⏰ Old Post

This post is over 9 years old - it might be slightly outdated and consigned to the history books.

We've added a new index to our tracking systems this week called "Premium Sites" - this is a list of over 10 million online businesses we consider to be of interest to the majority of people using the BuiltWith Pro service because they are implementing technology that is of interest.

This list will be continuously updated and thoroughly indexed as part of our new real time infrastructure. We've started by putting premium site totals into our free Trends data -

Premium Sites

One interesting metric that comes out of this is how many premium sites rely on open source tools. For example, the coverage totals above show that over 1 in 5 premium sites are using WordPress for a least one aspect of the web infrastructure.

This also means our free tech profile lookup tool will have much richer data for these additional 7 million businesses going forward.


BuiltWith® is a website profiler tool that tells you what a website is Built With.
