SERP Twin Engine
SERP Twin Engine helps you avoid keyword cannibalization: several of your pages competing for the same search. You enter your keywords, and the AI estimates how much SERP overlap each pair has. Pairs with high estimated overlap are clustered as "twins" that should share one page; the rest are recommended as separate pages.
Note that the overlap numbers are AI estimates of what the search results likely look like, not measured SERP data. Use them as a strong first sort, and verify borderline cases with an actual search.
Who it's for
Anyone planning content structure and wondering whether "best accounting software" and "accounting software comparison" need one page or two. The wrong answer costs either an unnecessary page or two pages knocking each other out.
Prerequisites
- 10 credits per analysis. Rerunning identical input is free from cache
- At least two keywords
Step by step
- Add keywords one by one, or paste a list with one per line into the bulk field. Duplicates are removed automatically.
- Run the analysis.
Reading the results
- The cluster cards show twins with a suggested primary keyword and page title. Cards flagged with cannibalization risk should be prioritized.
- Separate pages are listed with the reasoning for why they deserve their own page.
- The pair table shows estimated overlap per pair with a merge or separate recommendation.
- Copy sitemap structure gives you the whole recommendation as text for further planning.
Common problems
- "Could not parse the AI response": try again. Note that this particular failure is currently not refunded automatically; an identical rerun is, however, free from cache.
- Odd clusters: usually happens when the list mixes languages or topics. Analyze one topic at a time.
Limitations
- Overlap is estimated by the model, not fetched from search results.
- The number of pairs grows quickly with list size; very long lists analyze slower and more coarsely.
- Results are not saved; copy before closing.
