Website Similarity Analysis — compare sites by SEO score

Advanced Website Similarity Analysis API

What it does

Website Similarity Analysis compares a list of website URLs and returns a scored report for each one. Send URLs in the request body, and get back an overall similarity assessment plus site-level SEO and content findings.

The response includes a top-level tier, the service name, and timestamp, along with insights.global.explanation and an overall similarityScore from 0 to 100. It also returns insights.siteReports, where each website gets its own url, seoScore, aiSummary, and suggestedImprovements list.

Use it when you need to check whether multiple sites are too close in positioning, identify duplicated or overlapping content, or compare competitor pages in a market. The output is structured enough to feed into internal review tools, QA workflows, or automated SEO audits.

Website Similarity Analysis is useful when you want a fast, comparable read on a set of websites without manually opening each page and scoring them yourself.
