Keyword clustering is ESSENTIAL to making sure you\u2019re fully covering your topic, as well as preventing keyword cannibalization (when you have 2 or more articles fighting for the same keyword, leading to neither of them ranking well).<\/p>\n\n\n\n

Keyword cannibalization happens to even the best SEOs sometimes. Keyword clustering tools group your keywords together so all of these fall into specific topics and articles, so you don\u2019t create multiple articles for the same topic.<\/p>\n\n\n\n

The problem is, they often fall into two extremes: they either do ONLY keyword clustering and leave you doubting your keyword choices\u2026 or they add on a load of other features you don\u2019t need, and charge you for the privilege.<\/p>\n\n\n\n

Also, some keyword clustering tools just use basic AI prompts. This is just not anywhere as good as using proper machine learning and semantic technology to more accurately group keywords.<\/p>\n\n\n\n
