Search engines like Google scour the web to figure out how to rank content. But what if you want to know which of some 2000 technologies a web site is using? And, what if you want to know what the tech trends are across the 130 million largest sites on the web today? You could just dig through the source code for each site you’re interested in to answer these questions piecemeal, or you could repurpose other web site profilers designed for search engine optimization or other jobs.
By aggregating the data about usage across all of the sites that it tracks, BuiltWith can show which web technologies are gaining or losing in usage across the web. BuiltWith is monetizing all this publicly available but painful-to-aggregate data through a professional version called Trends Pro that lets people buy access to run custom reports across its database. Each report comes with further details on each included site, such as available contact information, and includes options to export to spreadsheets or into your company’s customer relationship manager software.
