When two pages from the same site trade places in the results for one query, both rank worse than a single page could — Yandex can't decide which is more relevant and splits the position between them. Not every overlap is a problem, though: sometimes it's a deliberate double presence in the top results.
This skill finds the overlaps and rules on each based on live SERP facts, not guesswork.
What it does
For a site connected to Yandex Webmaster, it finds queries where impressions are split across two or more of the site's own pages, paying attention to positions that jump day to day — a common sign Yandex is switching between URLs. For the most important of these queries, it also checks the live search results to see which page ranks today.
What you get
A chat table: query, competing pages, what's showing in search right now, and a verdict — merge (a 301 from the weaker page to the stronger one), interlink instead of merging, or leave alone if both hold stable, distinct positions — plus the winning page when a merge applies. The list starts with the highest-value queries.
