How LSI Keywords Improve Search Engine Ranking


If you are into online marketing then you must have heard of the word LSI keywords.

SEO has gone too far these days and people are using a number of ways to get a better rank on search engines. They create contents and use a number of keywords to get better ranking. But how to do search engines will know if there is a relevant content according to the search input or not.

Here comes the role of LSI (Latent Semantic Keywords). Let us understand it a bit deeper.

LSI keywords are a medium through which search engines get to know about the relevancy of the page to that of the search input. LSI keywords are basically those keywords which are similar to your main keywords or in other words, they are semantically related.

As per stats, LSI Keywords decrease bounce rate by 49%.

If in an article you are using ‘Microsoft’ and ‘Windows’ word as well then these are known as LSI keywords as they are based on a similar context. Here note that these are not the synonyms of each other. There could be a thousand example like using ‘Intel’ and ‘Processor’ at the same time.

Since there are a number of pages that talk about the similar kinds of stuff as the search input but it is not easy for search engines to distinguish between relevant and irrelevant pages. Search engines are making your browsing experience better and better. The concept of LSI Keywords is one of the ways to that.

Let us take another example to understand it. Suppose if you have written a blog about ‘love and relationships’ and no doubt it has the quality.

But if someone makes a similar input in the search bar of any search engine then how would the search engine know if your page is to be displayed or not. If your page is relevant or not.

If you have used the keywords like ‘bond’, ‘friendship’, ‘feelings’, ‘emotions’, etc then search engine will easily be able to recognize your page as a relevant one. These keywords are actually LSI keywords which help search engine to make decisions about the relevancy.

Why Google Uses LSI Keywords?

Gone are those times when you could just make your page stuffed with keywords and Google would consider it as a relevant page.

Keyword density was only a measure for Google to test the relevancy of the page to the search input. Google found out that people started using it very negatively and then Google came up with a solution and brought the concept of LSI keywords in SEO.

People were using cheap tactics to fool Google. They were just filling their page with keywords besides making the content relevant.

Users were not able to get relevant search results and were getting disappointed, Google found LSI keywords as an only solution to this. There was one more reason as well behind the concept of LSI keywords. Google was better able to understand the meaning of the web page and search queries through LSI keywords.

Now Google is better able to match the search input with the search results.

The Relation Between LSI keywords & Hummingbird

The semantic algorithm or Hummingbird algorithm was introduced by Google in the second half of 2013. It helps Google to better understand the context of the page and also focuses on synonyms.

Google has introduced this algorithm with an intent to provide users with better search results. Algorithms that were used earlier were only focusing on specific words that were present in the search input. But hummingbird algorithm checks for each and every word that falls under the radar of the search input.

Google is better able to match the search inputs with the search results due to the Hummingbird algorithm.

LSI Keywords & Better Ranking

Google is trying to provide its users with better search results. It is focusing on the whole context of the page rather than just the density of the keywords. Hence your page which is containing LSI keywords will get a better ranking because Google will be able to understand it in a better way.

Crossing the keyword density limit might be the concern of every writer because the content can get punished by Google on crossing the keyword density limit. You can keep using LSI keywords even if you have reached the keyword density limit. This will help you in getting better ranking as well.

Since Latent Semantic Indexing (LSI) keywords are similar to your main keywords hence providing you with a better ranking on search engines. You can conclude that you can get benefited from LSI keywords in SEO as well.

Hence LSI keywords can really help you in getting better rankings on the search engines and is an effective tool for online marketers.
