How can I reduce SEO cannibalisation between similar product pages on a large ecommerce site?
To reduce SEO cannibalisation between similar product pages on a large ecommerce site, ensure each page targets distinct keywords and serves a unique purpose. Consolidate pages with overlapping content and use canonical tags to guide search engines. Regularly audit your site to identify and address cannibalisation issues.

Why SEO Cannibalisation Matters
SEO cannibalisation is like having too many cooks in the kitchen. When multiple pages on your site compete for the same keyword, they dilute each other’s potential. This often leads to none of them ranking well. Imagine an online store selling different types of running shoes. If every shoe page targets “best running shoes,” they might all end up fighting for the same spot on Google. Not ideal.
This issue is more common than you think, especially on large ecommerce sites with vast product ranges. Each product page should ideally serve a unique purpose. If not, you’re essentially stepping on your own toes. The result? Lower rankings and less traffic. No one wants that.
Steps to Tackle Cannibalisation
To stop cannibalisation in its tracks, you need a plan. Here’s how you can sort it out:
- Keyword Differentiation: Assign unique keywords to each product page. This helps ensure that each page has its own spotlight. For example, instead of using “best running shoes” for every page, try “lightweight running shoes” for one and “trail running shoes” for another.
- Content Consolidation: If two pages offer similar content, consider merging them. This can strengthen the page’s authority and improve its chance of ranking higher.
- Use Canonical Tags: When merging isn’t an option, use canonical tags to indicate the primary page to search engines. This tells Google which page you prefer to rank.
- Internal Linking: Make sure your internal linking structure supports your SEO goals. Link related pages with relevant anchor text to guide users and search engines effectively.
- Regular Audits: Conduct regular audits to spot new cannibalisation issues. Tools like Google Search Console can help you track which pages are competing for the same keywords.
By following these steps, you’ll be on your way to a cleaner, more effective SEO strategy. Remember, it’s about clarity and focus.

Keeping It Real
Let’s be honest. SEO isn’t just a set-and-forget task. It’s a living, breathing beast that needs constant attention. That’s why working with a search engine optimisation expert can be a game-changer. They can help you navigate the complexities and keep your pages from tripping over each other.
So, what’s the takeaway? Make sure each page has its own space and reason for being. It’s like organising a massive family reunion. Everyone needs their own seat at the table, and no one should be left standing in the corner. Keep your content unique, your keywords distinct, and your site structure tidy. Your rankings will thank you.
