What is LSI (latent Semantic Indexing) & Why it is an effecting SEO Factor

by Dibyajyoti

LSI stands for Latent Semantic Indexing keywords, are conceptually related terms for search engines (Google, Bing, Yandex, etc ) use to understand the topic and category. In short , it finds the latent (hiden) relationship between words (semantics) in order to understanding contents (indexing). Another way if your keywords are Twitter , Facebook, Instagram, likes, Share then search engines will understand that page as social. Those affecting keywords are known as LSI keywords.

Why LSI Keywords are Important ?

In the early days search engines used the exact keywords matching , more use of synonyms to show results .

Example- If search engine find keyword “social media ” then it will think “this page is all about social media”. It will be categorized  as social media in SERp.


That’s why using main keywords was important that day. But the ages of “keywords matches and synonymy ” is gone.

But in present days, they prefer crawling your whole website to find keywords and understand it deeply . Simply, they understanding your page’s overall topic .


after those examples , I hope you have got overall idea about LSI keywords and how search engine relies on it . Let’s understand it broadly ..

You published the page about “Best Use of Social Media” ..But how exactly Search engine will scan it and which areas?

Here is the answer…


Yet , search engine will search for LSI keywords for better understanding. After finding all those , they will rank you in SERps accordingly .


After those examples you must understand , that latent semantic indexing keywords aren’t synonyms or alternative. They are nearly close meaning to them or they are being used in the same field.

For example, You chose word “Bathing” , you might think “Showering” will be the lsi keyword , Right ?

NO , “Showering” is only a synonym of “Bathing”. Don’t worry about it, you can use them for Page-SEO boost. But , we need to find the LSI keywords , which are “soap” , “towel” , “brush” , “bath-tub” , etc.

Coming to next question..
