What is keyword Stemming in SEO point of view?

Keyword stemming is a word that should be highlighted in the minds of everyone who plan to build a website on their own and look forward to succeed in the highly competitive area. Before we start talking about keyword stemming, we should gather a clear idea on what a keyword is. It is nothing else other than the word that we search for, and keyword stemming is bringing up the variants for the keyword by adding prefixes or suffixes to it. It is also done by stripping the suffixes or prefixes. It is a technique used by the search engines. Algorithms for keyword stemming have been studied in the field of computer science since 1968, says Wikipedia. The first ever published stemmer was written by Julie Beth. That was also in 1968.

Definition

Keyword stemming is the process of generating new words from the same root word. 

The Process of Generating New Words

The new word is generated with the help of the following options:-

 Adding a prefix to the word

 Example:- Adding "en" to the word "large"  makes it "enlarge".

 Adding a suffix to the word

 Example:- Adding "ful" to the word "sorrow"   makes it "sorrowful".

 Pluralizing the word

 Example:- Adding "ies" to the word "baby" makes it "babies".

This process helps webmasters and search engine optimizers to generate more traffic by creating words that are similar to their base keyword. Words generated with the help of the base word or stem are treated as synonyms by the search engines. For this reason, keyword stemming helps a web page to achieve greater relevance for search terms without the use of spamming.

A stemming algorithm reduces the words "practicing", "practiced", and "practices" to the root word, "practice".

Keyword stemming is a useful tool for web pages and search engine optimization. The process of keyword stemming involves taking a basic but popular keyword pertaining to a particular website and adding a prefix, suffix, or pluralization to make the keyword into a new word. 

When searching in Google, it shows results for the keyword query as well the similar to those terms and even at times in plural or singular form.
