In this article, let me take you on a tour of all about LSI Keywords. It is quite an interesting term. Before getting into how to find LSI keywords or how to use it to improve SERP ranking, let me clarify you, what LSI keywords are?

Understanding LSI Keywords

The principal goal of any search engine is to fetch search results matching what users want exactly. If your content page matches and comes in such search results, then it refers to SERP ranking. But, it is not that easy if you are focusing on a single keyword in your content.

Here the term LSI keywords have its significance.

What are Latent Semantic Indexing or LSI Keywords?

LSI keywords are the semantically related word or phrase to the primary keyword. It can occasionally be synonyms, alternative or substitution words. Latent Semantic Indexing algorithm analyzes the content with phrases that are synonymically or sentimentally in line with the main focus keyword. Google uses LSI principles to prefer pages that have well-informed content with real data rather stuffed with keywords.  

For an instant, entering a search query as “Ginger”, Google ends up with both the results about Ginger software for error-free English writing as well Ginger as a spice.

If you add a phrase or a word “medicine” to that, the search engine will get clear idea that you are searching for Ginger plant or spice. The word “medicine” is somehow relevant to the primary keyword “Ginger”.

Hope you might get the clear idea about LSI keywords and how Google uses it to refine the organic search results to match user’s search query.

To illustrate with an example; consider “Best automatic skateboard with handle for adults” – a long tail keyword that is more specific. On the other hand, consider “Paint Thinner” – here thinner is an LSI keyword. (Without that, it may refer to both Microsoft Paint and Wall Paintings). Paint thinner as a search query broadens the search scope.

How is it? Simply searching Paint Thinner may refer to “Using Paint thinner properly”, “Paint thinner specifications and price” and so on. Here, you can appear in search results for various search intent. With the use of related LSI keywords, your search range gets wider.
