Find queries where several of your own pages compete against each other, and see which one search engines actually prefer.
Check for Cannibalization
Cannibalization Report
What It Finds
The checker looks across your ranking keywords for queries where more than one of your URLs appears, or where the URL ranking for a query changes from check to check. Both are symptoms of the same thing: search engines cannot tell which page you meant.

week 1 /rank-tracker/ pos 12
week 2 /domain-overview/ pos 13
week 3 /rank-tracker/ pos 12Only the first and last rows are problems. Three URLs at 9, 24 and 41 means your strongest page is being held down by two weaker ones. The swapping row is the clearest signal there is: when the ranking URL alternates between checks, the engine is genuinely undecided.
The third row is not a problem at all. Two pages ranking at 4 and 11 for a guide query means you own more of the result page than a single URL could, and consolidating them would lose one of the two positions.
Cannibalization Is Over-Diagnosed
The word gets applied to any situation where two pages mention the same topic, and most of those situations are fine. Two pages ranking for one query is only a problem when they are competing for the same intent, when one is clearly weaker, or when the engine keeps changing its mind.
Merging pages is destructive and hard to reverse. Before consolidating, try the cheaper fixes: make the intent of each page unmistakable in its title and opening, and link from the weaker page to the stronger one with descriptive anchor text. That often settles it without deleting anything.
Questions
Should I merge every competing page?
No. Merging is destructive. Try clarifying intent and internal linking first.
Is ranking twice for one query bad?
Often it is better than ranking once. It becomes a problem when positions are far apart or when the URL keeps changing.
What does it cost?
It runs on credits, not a subscription, and credits never expire.
Check a query you suspect first. Most overlap turns out to be harmless, and knowing which kind you have is the whole point.
