Data Coverage

Depth & Quality

BuiltWith data has enough volume to provide a statistically relevant sample size for determining technology utilisation trends across the Internet.

We have a sufficient depth of coverage to give you more websites than you can use for marketing, sales and analysis.

Website Global Coverage

The Internet is mostly empty, really

There are a lot domain name/website addresses but most of them don't do anything. Our view is this:

• Websites outside the top 2 million get very little traffic
• Websites outside the top 20 million are static, generally very small sites
• We cover as much of the web as possible to be sure

Some numbers that back this up:

• 200 million top level domains (com, net, org etc), and 100 million country specific domain names (.uk, .ca, .au etc).
• 30% of top level domains are not renewed when registration expires.
• 15% have no websites
• 20% are parked with a single page website for monetisation, cybersquatting or domaining.
• A big % are held as brand protection and redirect to another website
• A big % are used as micro sites for marketing campaigns
• Quantcast estimates sites outside of the top 1 million globally receive less than 500 unique visitors per month.

Where our data comes from

We collect all of the website technology data internally. Over 5 years we have developed advanced (patent pending) algorithms. Everything we crawl is publically accessible and 100% legal.

Real time Analysis

BuiltWith Pro lets you analyze your own list of websites. Sites we don't already track are analysed on-demand with capacity to process thousands of sites per hour.
