How to Use Keyword Overlap Analyzer
- Paste two texts. Put your content in box A and the text you want to compare, such as a competitor page, in box B.
- Choose the stop word option. Ignore common words so the comparison focuses on meaningful keywords.
- Select Compare. The tool finds the words each text shares and the words unique to each one.
- Read the overlap. The summary shows an overlap score and the count of shared and unique words.
- Explore the tabs. Switch between shared words, words only in A, and words only in B to spot gaps.
Frequently Asked Questions
What does this tool do?
It compares two pieces of text and shows which keywords they share and which are unique to each, with an overlap score.
What is the overlap score?
It is a Jaccard score: the number of shared words divided by the total number of distinct words across both texts, as a percentage.
How do I use it for content gaps?
Look at the words only in the other text. Those are topics a competitor covers that you may want to add to your own page.
Why filter stop words?
Common words appear in every text and would inflate the overlap. Filtering them keeps the comparison on meaningful terms.
Does it fetch web pages?
No. You paste both texts yourself, which keeps the comparison private and works on drafts.
Is my data sent anywhere?
No. The comparison runs in your browser, so nothing you paste is uploaded.
