What is Keyword Cannibalisation?
Keyword cannibalisation is when two or more pages on your own site target the same search query and end up competing against each other. Google picks one, often not the one you wanted, and swaps between them week to week. Rankings become unstable. Links and engagement that should have concentrated on a single strong page get divided across several weaker ones.
Overlapping Query Competition
How overlapping pages hurt you
Search engines usually surface one page per site for a given query, so when three of your pages all address ‘serviced apartments Gurugram’ the system has to guess which you meant, and it may rotate between them from one crawl to the next. That is why a keyword sits at position nine one week and twenty-two the next with nothing changed on your end.
The deeper cost is dilution. Any backlinks you earn point at whichever page the linker happened to find, internal links spread across the set in the same scattered way, and none of it accumulates anywhere useful.
You can confirm it in Google Search Console. Filter to the query, add the pages dimension, look for one query returning several URLs with impressions. That is your evidence.
Why this keeps happening
Most cannibalisation comes from nobody owning the keyword map, so an independent writer publishes a post in March, an agency publishes a near-identical one in September, and neither checks what already exists on the site. Keep a shared sheet listing every published URL against its primary query. Check it before you commission anything. One habit, most of the problem gone.
Location pages are a frequent culprit. Separate pages for Gurugram, Gurgaon and Gurgaon Sector 44 that all say roughly the same thing will fight each other indefinitely. Pick one. Redirect the rest.
The fix is usually consolidation rather than deletion, so you merge the strongest material into one page, redirect the others with 301s, and update every internal link that pointed at a retired URL so the survivor inherits the full signal. Occasionally you keep two pages and differentiate the intent properly instead, which takes real rewriting.
What this looks like in practice
A hospitality group in Delhi NCR had four separate pages for banquet bookings, added over three years by different teams who never spoke to each other, and none of them ranked above position fifteen. Consolidating into one detailed venue page with capacity tables, seasonal pricing bands and a direct enquiry option gave the merged page a clear run.
The audit itself is cheap. An afternoon in Search Console and a spreadsheet. The rewriting is where the effort sits, and where most teams stall.

Keyword Cannibalisation — questions, answered.
Use Google Search Console. Filter to a single query, switch to the pages view, and check whether more than one URL is picking up impressions for it. Unstable positions with no other explanation are a strong secondary signal.
Redirect rather than delete. A 301 from the weaker URLs to the consolidated page preserves whatever links and history they had built. Delete outright only when a page has no traffic, no links and no content worth merging.
