SERP Similarity

This tool compares Google search results to cluster search queries based on the number of common results.

It can be useful to group a series of search queries that can be covered with a single content, to define "search-driven" editorial plans or to make decisions about a website architecture.

The results are taken via the Google Custom Search JSON API. Therefore, to use this tool you need an API Key and a Search engine ID: you can find more details on the Google's page dedicated to the API.
