Free Tool · Entity Gap Analysis

The words you need to add to be AI-optimized

Google and AI assistants like ChatGPT decide what your page is about from the topics it covers. Paste your page and a competitor page that outranks you — we read both, show the topics they cover that you're missing, count how often each one appears on both pages, and tell you where to add it.

Tip: compare the specific pages targeting the same search — not just your two homepages. We read exactly the pages you enter.

Frequently asked questions

What is an entity gap?

An entity gap is a topic, product, place or term that a competing page covers and yours doesn't. Search engines and AI assistants judge a page partly by the things it talks about, so a page that skips topics a reader expects can look less complete than a rival that covers them.

How does the tool decide what's missing?

It fetches the two exact pages you enter, reads their visible text, and asks an AI which topics the competitor covers that fit your page. Every suggestion is then checked against the real text: a term the competitor never actually uses is dropped, and so is one your page already mentions as often. What you see is a count, such as "they mention it 7 times, you 0".

Should I add every missing term to my page?

No. Add the ones that answer a real question your reader has, in sentences that explain them. Pasting a list of terms into a page doesn't help it rank, and it reads badly to visitors.
