Keyword cannibalization across URLs
When several URLs on your site receive impressions for the same query, Google must choose which page fits best—often splitting signals. Cannibalization hints help you decide whether to merge, differentiate, or canonicalize.
What we look for
From stored weekly Search Console facts, we group competing URLs per query and pick a preferred page using recent clicks, position, and impressions. Non-preferred URLs receive an issue row with context in extra_data.
What to do
Strengthen one primary URL for the intent, redirect or consolidate thin duplicates, or clearly differentiate pages so each targets distinct intents.
Example
If two URLs compete for the same intent, pick one canonical page and point the other to it (HTTP redirect at the server), or merge the content into a single URL:
<!-- Preferred primary URL: full product detail -->
<link rel="canonical" href="https://example.com/products/leather-tote" />
<!-- Secondary URL should either redirect (server-side 301) to the primary
or target a clearly different intent with unique title and copy -->
Technical details
