Your Pages Are Fighting. And Google Is Confused.
You have two blog posts about "email marketing tips."
You thought: more content = more chances to rank.
What actually happened: Google doesn't know which page to rank. So it ranks neither. Or it flip-flops between them weekly.
That's keyword cannibalisation. And it's one of the most common (and most damaging) SEO problems.
How Cannibalisation Hurts You
Diluted authority. Backlinks, internal links, and engagement signals are split across two pages instead of concentrated on one.
Ranking instability. Google alternates which page it shows, causing unpredictable ranking fluctuations.
Wasted crawl budget. Google crawls and indexes two pages when one would be more efficient.
User confusion. People might land on the wrong page for their intent.
How to Detect It
Method 1: Site Search
Search Google: site:yourdomain.com "keyword"
If two or more pages show up, you might have cannibalisation. Check if they target the same intent.
Method 2: Search Console
Filter by query. If multiple URLs show impressions for the same keyword, they're competing. Setting up proper tracking makes it easy to spot these issues early.
Method 3: Rank Tracking
Watch for keywords where different URLs rank on different days. That flip-flopping is a cannibalisation signal.
How to Fix It
Option 1: Consolidate. Merge the two pages into one comprehensive page. Redirect the weaker URL to the stronger one. This is usually the best option. We cover this approach in our keyword consolidation strategy guide.
Option 2: Differentiate. Adjust one page to target a different keyword or intent. Make them clearly distinct.
Option 3: Canonical tag. If you need both pages to exist, add a canonical tag to tell Google which one is the "main" version.
Option 4: Noindex. If one page adds no SEO value, noindex it and keep it for user navigation only.
Prevention Is Better Than Cure
Before creating new content, ALWAYS check if you already have a page targeting that keyword.
Keyword-to-page mapping prevents cannibalisation before it starts. Search Engine Journal has additional guidance on avoiding keyword overlap across your site.
