If you feel that the data behind SimilarSites.com can be useful to your website, or app, SimilarGroup has a solution for you.

SimilarGroup has developed unique algorithms which analyze all aspects of every website on the internet. With these algorithms, we have produced tremendously accurate results for website classification, similar website recommendations, and website tags.  We offer two API services which access this data.

Website Categorization API

This API takes a website request, and returns two categories. Each category is given a relevance score.  The output is delivered in XML format.

Similar Websites API

This API takes a request for a website.  The request then returns up to 20 similar websites which are ordered by relevance and also delivered in XML format.

Both of these APIs can be purchased at dev.similarsites.com.
