You supply the text. Nothing is fetched, and no search volume or ranking data is used or invented.

About this tool

Paste the HTML source or plain text of your page and of up to three competitor pages. The report lists terms and headings that competitors use at least twice and that appear nowhere on your page, grouped by topic, so you can judge which are worth covering.

It compares word overlap only. It suggests gaps and does not prove relevance, and no search volume, ranking or difficulty figures are shown because none are available. The text you paste is processed in your browser.

Reading the competitor pages directly from their URLs is an extension feature.
