What is LSI or Latent Semantic Indexing?

If you are in the field of SEO then you must be familiar with the term LSI. But if you are new to SEO then this post can help you boost your ranking. As the use of the LSI keywords can help you get more organic traffic and your website or blog will end up with loads of traffic.

Latent Semantic Indexing (LSI) is the term related to SEO and keyword density. Before understanding the LSI, you must be familiar with the word  “keyword density” so first check this post of mine “Ideal Keyword Density for SEO.” You must know that if you want to rank on Google’s first page then you should use LSI keywords along with the targeted keyword to avoid keyword stuffing and spamming of the keyword.

What Are LSI Keywords?

As I stated, LSI is another term that can be used for making SEO Better. The term LSI can also be known for using similar or synonyms words instead of using the Keyword again and again. When Google did not use the term Latent Semantic Indexing, people were concentrating more on keyword density. It was like that the more the keyword appears on the page; the more is the chance of getting to the first position. For example, if one website has a keyword appearing ten times on the page so the other has to put the keyword 11 times to beat that Website and Rank on the first of the search engines.

Those things now have been changed and these days Google updates its search engines and algorithms from time to time. Google is now smarter and uses LSI, which means Stuffing of the Keywords will harm the sites and will drag them down in the SERPs. So, instead of doing keyword stuffing, the original content will help a lot more. Let me explain to you with the help of an example.

Google uses LSI (latent semantic indexing) to check that the word being searched is actually about what like (place, company, food, or animal). For example – Suppose if you Search a word let’s say “Windows” Then, how Google will differentiate whether Windows is searched for wooden stuff, Windows is an Operating system or related to any other thing? Google uses Latent semantic indexing keywords to check what the searched word is about, if the words like operating system, installing windows, software system, and wooden structure appear in the article then it gets a lot easier for a search engine to determine that what the word is about “Windows OS” and will show the related terms for the same. For all these queries Google uses an algorithm named RankBrain to display better results on the Google SERPs.


All you need to know about Artificial intelligence.

What kind of Content is ranked higher?

The search engines are always looking for the most natural and relevant-looking content. Google only ranks that content that is not Spammy and overdone. As LSI is not any difficult thing, there is some simple logic that you can use for better ranking. Matt Cutts who was the Team leader of the Google Webspam team Says you should write content in such a way that people should link you back from their websites as a good resource for their articles. what he meant was writing content that is informative, and useful to both humans and Google bots, as the content which is Good with LSI keyword will be ranked by Google but if your content is being naturally linked by humans or the browser then the chances of getting ranked on Google SERPs increases by 90%.

So, the kind of content which will be ranked must be:

  • Unique
  • Well-written (grammatically correct, without spelling errors)
  • Keyword density should be good, must not be overdone.
  • The use of Synonyms/ LSI keywords must be there.
  • Content must be interlinked with your own website.

How can you find LSI keywords?

There are many ways of finding latent semantic indexing keywords. I will be telling all I know. Finding LSI keywords are similar to finding the longtail keywords, So, I will also recommend you to check my post on how to find longtail keywords. But for finding some perfect synonyms you should check the below tools.

You can also View the same LSI Keywords in the “search related to” results down at the Google SERPs.

2. Use of Keyword Planner:

Everyone searches on the Google keyword planner before doing anything. You can also find the same here. If you are a regular user of Google Keyword planner then you must be knowing that Google suggests some keywords based on the type of search conducted by you. And Those LSI keywords are the best ones to use in your articles or posts for better ranking.

3. LSI Graph/LSI Keyword Generator:

It is another fantastic tool for getting the best synonyms instead of the focus keyword. I use it too. And the reason I use it is that it provides many semantic words for the focus keyword and returns me the synonyms in no time.

How can you use it for Off-Page SEO?

Off-page is still important for the up-ranking of a website. And while making links, we can also use LSI keywords. We can use similar or synonyms of the keyword while doing social bookmarking, commenting on the blogs, and using other link-building techniques.

Some Tips for doing it Perfectly:

  • Use those sites which have high page rank or high domain authority for building links.
  • Write unique and relevant content.
  • Use the keyword in the Meta tags, title, and Meta description too.
  • Maintain an appropriate keyword density.
  • Do not use the same anchor text more than 5% instead use Synonyms to make quality links.
