Keyword Stemming is the process of using a popular keyword and modifying it in order to generate more hits from search engines.
Keyword stemming could be a really useful tool for web pages and search engine optimization. An example of keyword stemming could be if you took the word “guest blog” and made additional keywords out of words such as “guest blogging”, “guest blog” “guest blogger” and “guest blogs” .However, remember that Google doesn’t use keyword stemming for all search queries, uses a query-specific algorithm instead. It is important to know that ranking for a targeted term will depend on the user’s query.
