What is keyword cannibalization in SEO?

Keyword cannibalization is the phenomenon of having multiple pages on a website targeting the same keywords. This could occur because of duplicate pages or because two or more pages cover similar topics or target the same keyphrases.

It is important to deal with keyword cannibalization because pages that target similar keywords often end up eating away each other’s rankings.

How do I fix keyword cannibalization?

The way you fix keyword cannibalization issues depends on the specific issues that you’re dealing with. But to give a basic overview; in case you have duplicate content, it is advised to add the rel=canonical attribute which helps you prioritize a specific page over the other.

If two articles on your site attract the same audience you would be better off combining them. You can also use 301 redirects to achieve the same results.
