What is Keyword Stemming?
Keyword stemming is Google’s ability to understand different variations of the base keyword in a search query. For example, Google understands that run, runner, and running are related words. So, when you enter a search query containing runner, Google may return results containing run or running.
From the SEO perspective, keyword stemming allows bloggers to rank for keywords other than the one the searcher searched for. Back when Google didn’t understand the relationship between words, SEOs would typically include different variations of a keyword in their content so that it could rank for multiple related keywords.
However, SEOs no longer need to include variations of their base keyword in their content and just focus on writing naturally, as Google now understands the content without those additional keywords.
