Crawl budget waste – a term no search engine optimisation (SEO) specialist wants to hear, but a huge possibility with keyword cannibalisation. Apart from dropping rankings, low click-through rates (CTR) and scattered traffic, keyword cannibalisation can cause search engines to crawl duplicate content instead of prioritising unique ones.
Keyword cannibalisation happens when multiple pages on your site unintentionally compete for the same or highly similar keywords. Rather than building authority with well-optimised, engaging content on one page, you’re confusing search engines and diminishing your ability to rank by spreading keywords too thinly. While the root of the issue lies in poor mapping and unclear strategy, it often translates to pitting pages against each other and reducing the individual impact of your pages.
In this guide, we’ll take a look at where this usually happens and how to fix it.
Types of Pages Prone to Keyword Cannibalisation
1. Blog Posts
If your team regularly publishes content, it’s easy to end up with multiple blog articles targeting similar search terms. For example, two blogs titled “Travelling to Bali in 2025” and “Tips for Travelling to Bali.” While each has value, they may start competing for the same search intent, only with slightly different wording.
This is especially common on content-heavy sites where the blog archive grows fast. With different authors covering overlapping topics, lack of a coordinated content map and unclear keyword assignment, pages start diluting each other’s ranking potential.
2. Blogs vs. Product or Service Pages
Apart from your product or service pages, compelling, informative blogs can drive traffic to your site, educate your readers and increase your reputation as an industry expert. However, blogs can cannibalise your core conversion pages if they start ranking for identical keywords.
Let’s take a CRM product page, for instance. One of the keywords it’s supposed to rank for is “affordable CRM,” but a blog titled “Affordable CRM Tools for Small Businesses” was added to the mix and is outranking it. Now, users are landing on the blog post instead of the product page, and you potentially miss out on conversions.
It’s a classic case of content success working against your business goals. Meaning, if an informative blog pulls most of the organic traffic, users searching with the intent to purchase may read and leave without buying, resulting in higher bounce rates. When a blog outranks a service or product page, visitors may be led to a less effective page, and you risk losing sales.
3. Category Pages vs. Subcategory or Tag Pages
When ranking pages in search results, Google considers your site architecture. A well-structured website helps the search engine understand how your site is organised and which pages to prioritise, improving crawlability and indexing.
E-commerce websites frequently face keyword cannibalisation when their category and subcategory or tag pages overlap. For example, you might have a category for “knitwear” and a subcategory for “women’s knitwear.” If both pages are optimised for the same short-tail keyword, Google may get confused about which to rank.
Tag pages create another layer of complexity, often generating thin or near-duplicate pages with little original content, making it harder for Google to choose a primary page.
4. Homepage vs. Internal Pages
Although your homepage should be user-beneficial, it shouldn’t act as a catch-all, especially not for keywords better served by deeper, more specific pages.
This commonly happens with branded or broad keywords targeted by internal pages like “digital marketing agency.” Instead of ranking a tailored landing page built for conversion, your homepage takes the spot, offering a less targeted experience and resulting in wasted traffic.
5. Location Pages
Running an SEO campaign for a local business? It’s common to include multiple service area pages, such as “Plumber in Melbourne” and “Sydney Plumbing Services.”
However, by optimising around the same terms, search engines struggle to differentiate them. If both Melbourne and Sydney pages try to rank “plumber near me,” this leads to keyword cannibalisation. Without a clear strategy (distinct content focused on unique local features and proper internal linking to help Google understand the relationship between the pages), rankings shuffle across unintended pages.
This is why clear differentiation in content and intent is a must.
6. Landing Pages (PPC or SEO)
In hybrid campaigns using pay-per-click (PPC) and SEO strategies, landing pages can cause keyword cannibalisation.
Although landing pages are usually conversion-focused, conflict arises between your paid and organic strategy if they target the same keywords as your core SEO pages. Lacking proper coordination, these pages compete instead of complementing, weakening both ends over time.
7. Duplicate or Near-Duplicate Content
Unique, valuable content is always highly regarded. But in the past few years, Google has been doubling down on user-benefit content – it’s better to have one well-written and optimised page than copies on the same topic.
You may not even realise it’s happening. With blog syndication and a poor content management system (CMS) handling, different versions of the same article can live under separate URLs while targeting the same terms. That’s a recipe for keyword cannibalisation.
Even product pages with minor differences, like color or size, can cause duplication if the content isn’t distinct from one another. Search engines may index these pages separately and treat them as competing pages.
8. Paginated Series or Archives
Multi-part content, such as a three-part guide or archive pages, can divide keyword authority and cause cannibalisation. Without clear targeting or hierarchy and with pages using similar titles, headings and content themes, search engines may not know which to prioritise. Instead of working together, this usually results in poor performance across all pages.
Why It Happens: Mistakes Every Rookie Makes
Now that we’ve discussed the common pages causing keyword cannibalisation, let’s look at the why.
1. Unclear Keyword Strategy
SEO requires looking at the big picture and the little details. This means creating a structured keyword-to-page map to prevent overlaps.
Often, we focus on contextually rich content to answer a user’s query with relevant, high-quality information. However, without a centralised strategy, you may unknowingly target terms already covered elsewhere. Keyword mapping clarifies which page owns which topics, avoiding messy duplication down the track.
2. Publishing Content That’s Too Similar
Publishing a blog about your team’s favourite marketing tips but rehashing information from another piece already on your website? You may want to rethink that. We often focus on “refreshing” old topics or targeting variations within the same ideas, which can lead to duplicate themes.
3. No Content Architecture or Planning
When websites grow without a content hierarchy or topic cluster strategy, things get scattered. You might end up with four blog posts, two landing pages and a whitepaper, all vaguely about the same thing. And search engines will not know which to rank.
4. Duplicate or Near-Duplicate Pages
Product variations with colour or size, poorly managed tag archives or even a CMS setup creating multiple URLs for mobile versions can result in almost identical pages. Although usually stemming from technical issues, it requires active monitoring.
5. Overusing Broad Match Keywords
It’s normal to target broad terms users commonly search for, like “top headphones.” However, when this keyword is covered across every other page, it might sound like the best way to cover all your bases, but cannibalisation is just waiting to happen.
Here’s where long-tail and intent-based keywords come in handy, shifting the focus to semantic content instead.
6. Zero Coordination in SEO Optimisation
It’s common for different teams (products, blogs, paid search and more) to optimise pages independently. A good SEO agency should provide proper keyword mapping so teams across departments can work from a shared plan, preventing overlap.
7. Poor Internal Linking and Anchor Text Strategy
Internal links help search engines understand your site structure. So, it’s no surprise how inconsistent or keyword-stuffed anchor text can confuse them on which page is the most relevant for a topic.
8. Lack of Regular SEO Audits
As your content library grows, cannibalisation builds up unless you’re cleaning up with regular audits. Most sites start running into this issue after publishing over 50 pieces of content without proper keyword governance.
How to Spot Keyword Cannibalisation in Pages
Here’s how to check if your keywords are being split across pages or not ranking in their intended URL.
Use Google Search Console (GSC)
To look for multiple pages appearing in search results for the same keyword, head to GSC and search for a specific keyword. It’ll list the URLs ranking for your term, and if multiple pages from your site are showing up, that’s your next fix.
For example, an e-commerce site may find its category and product page ranking for “gondola shelving.”
Use Historical Rankings in Keyword.com
In Keyword.com, you can check which URLs have ranked for each keyword over time with historical rankings. There’s likely a cannibalisation issue if the URL keeps changing or switching between pages.
If you want to check across multiple pages, simply export a full keyword ranking report and compare the current landing page rankings with your intended URL map using a simple IF function in excel =IF(A1=B1,”Match”,”Not Match”). If they don’t match, there’s a high chance of cannibalisation.
Simple Steps to Fix Keyword Cannibalisation
Found an issue? Here’s what you can do to make sure your keywords are ranking for the correct landing page:
1. Deoptimize the Canonicalised Pages
If a secondary page is ranking when it shouldn’t, start by removing the target keyword from the title, meta description and heading tags. This helps shift the focus away from those pages, signalling to Google that another page is the better fit.
2. Add Internal Links Pointing to the Right URL
Use keyword-rich anchor text on the canonicalised pages to link to the page you do want to rank. This redirects SEO authority and reinforces relevance for that term.
3. Consolidate and Redirect Pages
If the secondary pages don’t offer unique value, consider merging their content into a single, stronger piece. Then, redirect those pages to the intended one.
