It is common knowledge among digital marketers that keyword plays a major role in SERPs.

Therefore, increasing the reach of keywords by a technique used to get more hits using “keyword stemming”  is our aim. How do we achieve it is the theme of this blog.

Knowing the intention of browser searching and giving relevant content is search algorithms‘ main aim. Keyword stemming is useful and helps our SEO better.

Understanding Keyword Stemming

What is keyword stemming?

“In linguistic morphology and information retrievalstemming is the process of reducing inflected (or sometimes derived) words to their word stem, base, or root form—generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. Algorithms for stemming have been studied in computer science since the 1960s. Many search engines treat words with the same stem as synonyms as a kind of query expansion, a process called conflation.”   Wikipedia

Conflation is “the merging of two or more sets of information, texts, ideas, etc. into one.” Dictionary

It is exactly how Google interprets and makes sense of different word forms and groups them together and tallies them as the search terms. Thereby your Search Term in the blog is returned to the Search Engine Return Pages for the respective browsing query.

In addition to the older practice of matching the exact keyword or phrase match of a Key Term Stemming words are also selected by the algorithms

When we consider connotation, we are talking about the ability of the algorithm to the semantics of different search words, and expressions used to convey the same sense of the keywords.  And it (algorithm) can match various stem word forms of a certain watchword. 

How stemming improves SEO

Having understood, now we will consider what part the derived stemming word plays in Search Engine Optimization. 

Why do we need to take note of the fact that synonyms should be added to the SEO analysis? 

The search term may not be the same as the keyword you used in an article. Your article may be about the same topic, but with a different keyword or phrase. So, the search engine may not consider it relevant for other semantically generated words, unless, you include them.  

And accordingly, use words that convey the same sense or meaning. 

Benefits of including branching words.

There are two benefits of Stemming.

  • Offset the narrowing of the longtail keyword.
