Search engine optimisation has evolved significantly over the years. Earlier, websites could rank by focusing on a few individual keywords and repeating them across pages. However, search engines have become much more intelligent and now focus on context, relevance, and user intent. Because of this shift, digital marketers have adopted advanced techniques such as keyword clustering to improve search visibility and create more effective content strategies.
