Dump ‘Keyword Density’ as your content optimization method. Google has forgotten it and it’s time you did too. Surprisingly though, many so called SEO experts are still pushing this when they talk to their clients about optimizing websites. Google algorithms have become smarter and use LSI keywords, the full form is Latent Semantic Indexing.

Google’s shift from keyword density to LSI Keywords

In the early days, Google ranked webpages based on keyword density. If your content mentioned “latest fashion trends” numerous times then the older search engine algorithms would consider that your webpage is about fashion trends and bring up your page when the keyword was used in search. And that is why keyword density was important – a few years ago. It is no longer the case.

Now, search algorithms use Artificial Intelligence and this means that no longer is it possible to just stuff your content with a few keywords. The new search ranking algorithms are using Latent Semantic Indexing to decide on the contents topic and relevancy to a user’s search.

What is LSI in SEO

LSI Keywords is what makes content understandable in the same way to both a machine reader and a human reader. Machine readers are nothing but algorithms that decide on the relevancy of content to feature it in the Answer Box(rich snippets that come in the form of questions at the top of search results) which is a big ranking signal for authority, as well as SERP. Coming in the first 10 results in Search Engine Results Page is when your page content beats out other pages for relevancy to a given search query. All this happens because of LSI Keywords.

Latent Semantic Indexing is a mathematical technique that looks for keywords related to the main keyword. If the search query is “Cars Prices in India”, Google needs to differentiate between the movie “Cars” and the product on sale. It does this by looking at the web of keywords that come together in the content to decide whether it needs to pick up content on different cars sold in India and leave out the story about the animated movie “Cars”.

Another one for the LSI Keyword examples can be this page. If you searched for “LSI Keywords for SEO” then mathematical algorithms will have crawled this page and recognized the LSI keyword web for this term in the content

How to Use LSI Keywords in Your Content

The point of using LSI keywords is that it must fit naturally into your content. However, there are a few tips on the best way of including these keywords so that your content gets ranked higher in search results.

  • Primary and secondary LSI Keywords: Let’s say you have chosen 5 LSI keywords to appear in your content. The next step is to decide on the frequency each keyword should appear. Those with higher search volume should be included 3 to 5 times. The secondary keywords can appear at least twice.
  • It is recommended that your main LSI keyword appear in your Title. Others can be used in the Header tags, such as sub heading H1 and H2 tags.
  • If your LSI keyword can be included in the page URL, that would be ideal.
  • Ensure that an LSI keyword appears as high as possible in the first paragraph. Also include one in the last paragraph. Distribute the remaining keywords in the content.
  • When you write the meta description (for search result page) make sure it includes at least one LSI Keyword.
  • Use a suitable LSI keyword in Anchor Tags.
