How this service works

Given a set of specific page URLs, find the Google keywords those pages jointly rank for, with each page's position, URL and estimated traffic (ETV) per keyword, plus search volume, CPC, competition, difficulty and intent. Page-level, not domain-level. Optional exclude_pages narrows to keywords the pages rank for that others do not.

Output

Returns a list of keywords (up to the specified limit, default 50) that all provided page URLs share in common Google search rankings, filtered by the given language and location. Each result represents a search term for which all the input pages appear in rankings simultaneously. Keywords appearing on any excluded pages are omitted from results.

Example use cases

Content gap competitive analysis

“What keywords do https://backlinko.com/hub/seo/link-building and https://ahrefs.com/blog/link-building-strategies share in their US Google rankings? Give me up to 50 of them.”

Internal content cannibalization check

“Find the keywords that https://myblog.com/best-coffee-makers and https://myblog.com/coffee-maker-reviews both rank for in English US results — show me up to 100 shared keywords so I can see if they're competing with each other.”

Niche topic cluster discovery

“I want to find keywords that https://healthline.com/nutrition/keto-diet and https://dietdoctor.com/low-carb/keto both rank for in Google, but that https://webmd.com/diet/what-is-ketosis doesn't rank for — return up to 75 results in English.”

When to prefer

Use this endpoint when you need to identify keyword overlap between specific pages (not entire domains) — ideal for competitive content analysis, detecting internal cannibalization, or finding shared topic clusters. Prefer this over domain-level keyword tools when the comparison is page-specific. Choose this over a keyword gap tool when you want intersection (what they share) rather than exclusion (what one has that the other lacks).
