Keyword cannibalization

Two of your own pages, one search

It usually starts innocently. You write a blog post about water heater repair. Two years later somebody builds a proper service page about water heater repair. Neither one is bad. But an engine looking at that search now has two candidates from the same site and has to guess which one you meant to be the answer.

The guessing is the problem. It may land on the blog post, which has no phone number near the top and no service area on it, and leave the page that was built to take the call out of sight. Or the two swap places over time, which reads like a ranking that will not settle.

Whatever credit you have built gets divided as well. Half the sites that mention you point at the post, half point at the service page, and neither one ends up carrying the weight a single page would have carried.

Where this bites a local service business

The local version has a specific shape: city pages. A company covers six towns, writes a page for each, then writes a seventh for the county that contains all six. All seven aim at roughly the same handful of searches, and none of them is clearly the one.

The same thing happens with words instead of towns. A page for emergency plumber and a page for 24 hour plumber are describing one service to one person in a hurry. Splitting them felt thorough at the time. What you built was two doors into the same room, and something has to decide which door to show.

The cost is not a penalty. Nothing gets flagged, nothing gets a warning. You simply spend money and attention on pages that split what one page could have held, and the page that finally shows up is often not the page you would have chosen to greet a customer.

It is easy to miss too, because every page looks fine on its own. What gives it away is behavior: which page people actually land on, and which page produces a ringing phone. First-party lead dashboards running on more than 20 of the sites we manage exist for exactly that kind of question.

Deciding which page owns which search, and what becomes of the rest, is ordinary SEO work rather than a rescue operation.

A targeting problem, not a punishment

Nobody is penalizing you for it. Cannibalization is what happens when a site grows one page at a time and nobody decides, in advance, which search each new page is for.

The repairs are unglamorous and they depend on the case. Give one page the search and point the others at it. Merge two half answers into one page that actually answers. Or leave both alone, because they serve different intents: a page about what a repair costs and a page about how to book one are not competing, even though they share most of their words.

The test is not whether two pages use the same phrase. It is whether somebody typing that phrase would be satisfied landing on either one. If either would do, you have one page worth of work spread across two.
