Once you’ve been writing content for a while you might have dozens of articles on any given topic. If these articles are kind of saying the same things, search engines and users might get confused. Because you have so much similar content, your content might compete against itself in the search engines. This is called keyword cannibalization. It’s not inherently bad, but it is something you need to take a look at. Are your articles performing as well as they should or is the competition hurting the chances at a higher ranking? Luckily, it’s not hard to find and fix keyword cannibalization.
