What is keyword cannibalisation and how do you fix it?
Keyword cannibalisation happens when two or more pages on your website target the same search term, so they compete against each other in Google instead of working together. The usual result is that neither page ranks as well as it should. The fix is usually simple: spot the competing pages, keep the strongest one, and redirect or merge the rest.
How keyword cannibalisation happens
It is easy to do by accident. You write a blog post about SEO for plumbers, then a second post about plumbing SEO a few months later, then a service page for the same phrase. Google now has to choose which page deserves the top spot, and it often cannot, so both rank worse than they would alone.
The classic warning sign is two of your URLs appearing for the same query in Google Search Console, with each page taking a handful of clicks from a position far lower than you would expect.
How to spot it in Search Console
Open the Performance report in Google Search Console and look at the queries that bring you impressions. If one query shows two or more of your own URLs, that is cannibalisation in action. Sort by position and you will usually see both pages sitting in the same band, say positions 9 and 14, each grabbing a small share of clicks.
Check the pages report too. A single keyword with several of your pages fighting over it means Google is unsure which one to trust. The more focused your site, the clearer its signals.
How to fix keyword cannibalisation
There are three reliable fixes, and the right one depends on how similar the pages really are.
If the pages cover the same ground, consolidate. Keep the strongest page, move the useful content from the others into it, then set up 301 redirects from the losing URLs to the winner. This passes the authority of the old pages into one clear target. Our guide to 301 redirects explains how the redirect itself works.

If the pages are genuinely different, differentiate them. Give each its own keyword, rewrite the titles and headings so they stop competing, and link between them with descriptive anchor text. Sometimes two pages just need clearer jobs.
If one page has no real value, prune it. Delete the thin page rather than leave it competing with a better one. A smaller, stronger site outranks a sprawling one that says the same thing twice.
Whichever route you take, keep the strongest page as the destination. That is usually the one with more backlinks, more traffic, or the clearest match to the search intent.

How we approach it for clients
When we take on an SEO campaign, one of the first checks we run is for keyword cannibalisation. We map every page to its primary keyword, find the overlaps, and agree a consolidation plan before anything is rewritten. It is a fast, high-impact fix: resolving a few competing pages often lifts the whole cluster in the rankings.
If you are not sure whether your own pages are competing, start with a free SEO report at https://victory.digital/run-a-seo-report/. For the full picture, our search engine optimisation services begin with a technical audit that maps every page to its keyword.
