LSI keywords are one of the primary ranking factors for Google’s algorithm. LSI keywords are words and phrases that Google believes are related to your main keyword. These related words make a huge difference in how you optimize your content. In this blog, we are going to go over what LSI keywords are and how you can use them to improve your Google rankings.

What is an LSI keyword? 

LSI keywords, also known as latent semantic indexing keywords, are a type of search engine optimization keyword that is used to help search engines understand your content better.

LSI keywords are a great way to increase search engine traffic to a site. LSI keywords are related to your main keywords from a different angle. For example, if your main keyword is “how to lose weight fast”, you can consider LSI keywords like “how to lose weight”, “weight loss”, “weight loss program”, and “how to lose weight fast at home”. This way, you will cover a wider range of search queries and improve your SEO.

Keyword Density

Keyword density is the percentage of how many times a keyword appears on your page in comparison to the total number of words on the page. 

However, Keyword density is calculated by taking the number of times a keyword appears on your page and dividing it by the total number of words on the page. For example, if your keyword appears 3 times on a web page with 300 words, then the keyword density is 10%.

Marketers didn’t care about context while using target keywords and repeated them as much as they pleased. As a result, websites that offered readers little value frequently scored higher.

With the development of more sophisticated algorithms, search engines like Google ceased taking keyword density into account when determining SEO. Instead, they began focusing on a web page’s content and relevancy in order to rank it.

What Advantages can LSI keywords offer? 

The content-targeted search results are being replaced by a more personalized set of search results by Google. This is because Google wants to give you the best search results for your queries; which may not always be those that are directly related to your search terms. Google is testing a new way to deliver more personalized search results in which the search engine delivers results based on your previous searches and the items that are most relevant to your previous searches. This is a natural progression from the use of Latent Semantic Indexing (LSI) keywords.

Let’s quickly discuss the benefits of using LSI keywords

  • Search engines are able to better comprehend your content and increase its ranking power by scattering LSI keywords in your content.
  • By including relevant keywords, you can avoid “keyword stuffing,” – the practice of using too many keywords in a piece of writing.
  • Additionally, LSI keywords help you in delivering visitors a better search response, which enhances several ranking metrics, including spending time on a page, click-through rate, and more.

What are the Disadvantages of LSI keywords? 

 LSI keywords don’t have any major disadvantages. For instance:

  • It eliminates all coordinating conjunction and prepositions and doesn’t take word order into account.
  • It holds that there is just one meaning for each word.
  • Sarcasm and underlying concepts are ignored. The words’ interpretations may not always correspond to the text’s interpretations.

When did LSI keywords come into play? 

If you’re curious about when LSI keywords started, it all began in 2004 when Google’s search engine incorporated latent semantic indexing. Its objective was to help the search engine offer visitors more pertinent recommendations.

Google, though, wasn’t only interested in keywords. The dominant search engine also sought to comprehend relevant keywords in hyperlinks; and a bunch of websites that connect to one another.

All of this was modified by one algorithm tweak, which fundamentally altered the way Google presents search suggestions.
