keyword cannibalization

Keyword cannibalization is when two or more pages on your own site compete for the same search. Google has to choose between them, often picks a different one each week and ranks neither as well as a single page would. The usual causes are a service page and a blog post on one topic, or near-identical location pages.

It is not the same as covering a topic from several angles. A page on 'divorce lawyer' and a page on 'how long does a divorce take' serve different searches. Cannibalization is two pages trying to be the answer to the same one, and the cure is almost always to merge or to give one of them a different job.

Short version: two of your pages fighting for one search, and both losing.
Why it matters for your business

Your competitor is often
your own website.

A law firm publishes a 'Family law' service page, then a 'Family law services' blog post, then a 'Family lawyers in Manchester' location page. Three pages, same search, each with a third of the links and a third of the authority. Google rotates between them, the ranking never settles and the firm pays an agency to 'improve' a page that is competing against its own siblings.

It also hides inside good news. A content plan that produces four articles a month will eventually produce two on the same topic unless someone keeps a map of which page owns which keyword. If your monthly report shows a keyword where the ranking page keeps changing, that is cannibalization, not volatility.

The fix is cheap and unpopular because it means deleting or merging pages you paid for. Merge the weaker into the stronger, redirect the old address and give any genuinely different page a genuinely different search to own. Rankings usually recover within weeks.

Example

Three pages for 'divorce solicitor',
none of them on page one.

What the firm had

A service page, a blog post written to 'add content' and a location page with the same paragraphs and the city name swapped in. Search Console showed all three appearing for 'divorce solicitor manchester', in turn, between positions 9 and 18.

/services/divorce/ /blog/divorce-solicitors-what-we-do/ /manchester/divorce-solicitor/
What fixed it

The blog post was merged into the service page and redirected. The location page was rewritten to answer a different search, 'divorce solicitor near Manchester Crown Court', with directions, parking and which courts the team appears in. One page now owns the main search, the other owns a specific one. The service page settled at position 4 within six weeks and the enquiries moved with it. Fewer pages, more clients.

How to check it on your site

Four checks for pages eating each other.

Tick each one as you go. 0 of 4 checked on your site.

  1. Search Console: one query, which pages?

    In Google Search Console, open Performance, click a target search in Queries, then switch to the Pages tab. One page is healthy. Two or more pages, each with impressions, is cannibalization. Do this for your five most important searches.

  2. Search site: plus the keyword

    Type site:yourdomain.com divorce solicitor into Google. Every result is a page Google considers relevant to that phrase. If the first three are all meant to be the answer, you have found the overlap.

  3. Look for pages that keep swapping

    In the Performance report, compare two periods for one search. If the page that ranked has changed and the position bounced, Google is flipping between your pages. A page that is stable but low is a different problem.

  4. Compare the title tags

    List your pages with their title tags in a spreadsheet, or export them from your CMS. Sort by title. Two titles that are nearly identical are two pages targeting the same thing, whatever the body says.
