If you’ve noticed your SEO rankings slipping or you start to experience lower conversion rates, you may have a keyword cannibalization issue where your site is targeting the same keyword on too many pages.
The good news is, fixing keyword cannibalization isn’t incredibly difficult, and with a little bit of knowledge and careful planning you can prevent the problem from happening in the future.
What Does Keyword Cannibalization Mean?
Keyword cannibalization occurs when multiple pages on your website target the same or very similar keywords, leading to confusion for search engines. Instead of supporting each other, these pages compete for the same search rankings. This can dilute your SEO efforts, resulting in lower rankings and reduced traffic across all pages.
When multiple pages compete for the same keyword, it confuses search engines about which page is most relevant for the target keyword. This might lead search engines to rank pages that are less important or less relevant higher than more critical pages, or it could result in fluctuating SERP (search engine results page) positions as search engines attempt to determine the best match.
Common Instances of Keyword Cannibalization
- Duplicate Pages: Duplicate pages occur when two or more pages on a website have essentially the same content but are accessible through different URLs. These duplicates can compete against each other for the same keywords, confusing search engines about which page to rank higher.
- Category Pages: In ecommerce or large content sites, category pages can often end up competing against each other for the same or similar keywords. For example, a general category page for “women’s shoes” might compete with sub-category pages for “women’s running shoes,” “women’s boots,” etc., if not properly structured and optimized.
- Landing Pages: Businesses often create multiple landing pages to target specific regions or audiences. However, if these pages are too similar or have the same search intent (like “best digital marketing services New York” and “best digital marketing services NYC”), they can cannibalize each other’s traffic.
- Multiple Blog Posts Covering the Same Topic: A blog might have multiple posts that target similar themes or questions, such as different articles explaining aspects of SEO that all target “how to improve SEO.” If these posts are not distinct enough in their content and keyword focus, they can end up competing for rankings.
- Product Pages with Similar Products: Similar product pages, especially those with slight variations (like color or size), might all target the same keyword. For example, separate product pages for a t-shirt in different colors might all target “comfortable cotton t-shirt.”
How Does Keyword Cannibalization Affect SEO?
SEO is a complicated process that includes multiple factors that affect search rankings. Keyword cannibalization can have a direct affect on many SEO factors.
Diluted Page Authority
When multiple pages target the same keyword, none of these pages can accumulate the full potential of incoming links and content depth compared to having a single, comprehensive page. This can make it harder for any one page to stand out in search results. Search engines look for authoritative pages that offer in-depth content on a topic, and if the authority is spread across several thinner pages, none may appear as the definitive source for the target keywords.
Lowered Conversion Rates
If users are distributed across multiple similar pages, they may not be directed to the page that is best optimized for conversions, whether that’s through better call-to-action placements, more persuasive content, or a more user-friendly layout. Since not every page will be equally effective at converting visitors, traffic may not be directed to the best-converting page, which could impact your overall site conversions.
Wasted Crawl Budget
Search engines allocate a certain amount of resources to crawl each site, known as the crawl budget. When a site has multiple pages that target the same keywords, search engines spend part of this budget crawling and indexing multiple similar pages. This is inefficient and can lead to more important pages being crawled less frequently or new content taking longer to be discovered and indexed.
Confusing User Experience
Users expect to find the best, most relevant content in response to their search queries. If they encounter multiple similar pages within the same site, it can be confusing and lead to frustration. This may result in users bouncing back to search results to choose another source, increasing the site’s bounce rate and reducing overall user engagement and satisfaction.
Identifying, Fixing, and Preventing Keyword Cannibalization Issues
Identifying Keyword Cannibalization
Spotting keyword cannibalization early can help maintain the health of your SEO efforts. Here are some ways to identify a keyword cannibalization issue:
Use Analytics Tools
Using SEO and analytics tools like Google Analytics, Ahrefs, or SEMrush is one of the most effective ways to identify keyword cannibalization. These tools allow you to see which keywords are driving traffic to your pages. You can identify when multiple pages are ranking for the same keywords by taking note of fluctuations in traffic between similar pages, where they seemingly compete for attention during similar time frames.
Perform a Site Audit
You can do a website audit to review your website’s structure, content, and existing SEO strategies. This can be done manually or with the help of SEO tools. During an audit, look for multiple pages targeting the same keyword, similar content themes, or meta tags that might be targeting the same search queries.
Create a Keyword Map
Keyword mapping is the process of assigning specific keywords to relevant pages on your website in order to optimize each page and prevent different pages from targeting the same keywords. Start by listing all the pages on your site along with their main focus and the keywords they are intended to rank for. Then, you can easily spot redundancies and gaps in your keyword strategy.
How to Fix Keyword Cannibalization
Once you identify the problem, you can eliminate keyword cannibalization issues by making some adjustments to your SEO strategy and your current content.
Reevaluate Your SEO Strategy
Start by reviewing and refining your SEO strategy to ensure that each page on your website has a unique role and targets relevant keywords. Make sure there is a clear search intent behind each keyword and align it with the content of the respective page. By clearly defining the purpose of each page, you can identify the. most relevant keywords for each page and avoid overlaps and competition among pages.
Merge Similar Content
When multiple pages cover similar topics and target the same keywords, it’s often more effective to merge these into a single, comprehensive page rather than risking your audience going to the wrong page. After merging, the consolidated page is likely to perform better in search engine rankings due to its enhanced authority.
Use 301 Redirects
After merging pages or removing redundant ones, it’s important to implement 301 redirects. These redirects permanently point old URLs to the new, consolidated page. This helps in guiding both users and search engines to the most relevant and updated content. This also ensures a smooth transition and minimizes any negative impact on your site’s SEO.
Adjust Internal Linking
Optimizing internal links is another effective way to combat keyword cannibalization and boost search rankings. By ensuring that all internal links pointing to a particular keyword direct to the same, most authoritative page, you reinforce to search engines which page is most relevant for that targeted keyword.
Prevent SEO Keyword Cannibalization
The good news is, preventing keyword cannibalization is often much simpler than fixing it. With a little bit of keyword research and content strategy, you can prevent the issue from happening in the future.
Plan Your Content Strategy
Develop a clear content strategy before creating any new pages. Your strategy should outline the purpose of each page, the target audience, and the specific keywords or phrases it will target. A well-planned content strategy also helps align your content with your business goals and user needs, making your website more coherent and targeted in its approach to different topics.
Conduct Regular Keyword Reviews
Make sure to do a regular review of the keywords your pages rank for so you can identify potential keyword cannibalization. By monitoring keyword performance and how each page ranks, you can spot potential issues early on.
Tools like Google Search Console provide insights into the search terms that bring users to your pages, allowing you to adjust your content and SEO strategies as needed.
Utilize Canonical Tags
Canonical tags are a technical solution for managing similar content that serves a necessary purpose (like printer-friendly versions of pages or content that is accessible through multiple URLs). By specifying a canonical URL in the HTML of each page, you can inform search engines which version of the content is the “master” or primary version that should be indexed. This helps avoid confusion when there are multiple similar pages and ensures that search engines concentrate all ranking signals (like links) towards the canonical page.
Common Challenges in Addressing Keyword Cannibalization
We know it can be difficult to address these complex SEO issues if you aren’t dealing with them on a day-to-day basis, so we’ve compiled some of the most common challenges in addressing keyword cannibalization, as well as some quick tips to overcome those challenges.
Identifying The Issue
One of the primary challenges is actually recognizing that keyword cannibalization is happening. Some businesses may not have the tools or expertise to analyze their SEO data deeply. Without a clear understanding of what to look for, it can be difficult to spot the signs that multiple pages are competing against each other rather than complementing each other.
Tip: Utilize tools like Google Search Console or Ahrefs to regularly monitor your SEO performance.
Complex Website Architecture
For websites with a large number of pages or complex structures, addressing keyword cannibalization can become particularly challenging. Large e-commerce sites, for instance, might have multiple product pages that inadvertently target similar search queries.
Tip: Implement a clear hierarchical structure and a well-defined internal linking strategy that clearly maps out primary and secondary keywords for different sections and pages of your website.
Resource Allocation
Addressing keyword cannibalization often requires resources in terms of both time and personnel. Analyzing SEO data, rewriting content, restructuring website architecture, and implementing redirects are all resource-intensive tasks.
Tip: Prioritize the most critical pages for quick wins in your SEO efforts and consider outsourcing complex tasks to SEO professionals to optimize resource use.
Balancing User Experience and SEO
Sometimes, what’s best for SEO isn’t always ideal for user experience, and vice versa. Deciding whether to merge, delete, or restructure content involves balancing these aspects so that one doesn’t adversely affect the other.
Tip: Conduct user testing and gather feedback when merging or restructuring content to ensure the changes enhance user engagement and comprehension.
Continuous Monitoring and Adjustment
SEO is not a set-it-and-forget-it strategy. Even after addressing keyword cannibalization, continuous monitoring is necessary to ensure the problem doesn’t recur as new content is added. This requires an ongoing commitment to SEO best practices and regular audits.
Tip: Set up a routine schedule for SEO audits and content reviews, making adjustments based on emerging trends and the addition of new content to maintain a healthy, cannibalization-free website.
