All about LSI keywords and why they’re important

SEO is slowly getting into a new stage of existence.

Keywords in their current form are becoming less and less important. Instead, Google focuses on determining the overall meaning of an article. Nowadays, typing in certain words or phrases doesn’t necessarily mean that you will get articles filled with them. You might get something completely different yet relevant.

For some time now, Google has been developing systems that will discover the true meaning behind the words. Such an approach can only be beneficial for users as it gives us proper answers to our questions.

With all that being said, LSI keywords have become the most important factor during content creation. Let’s talk about it.

What are LSI keywords?

LSI stands for latent semantic indexing. It is a concept that determines importance of a word within a corpus (body of text). Based on that, it is easy to determine that LSI keywords are the keywords that are important to your article.

As mentioned, focusing on a single keyword is no longer lucrative.

There is no way for Google to determine whether use of this keyword is random or intentional. At least not without LSI keywords.

With LSI keywords everything changes.

They are a set of words and phrases which helps describe content more thoroughly. It provides depth to the article allowing Google to precisely determine what it is all about.

Example of LSI keywords

Let’s say you are writing a thorough article about a country.

Of course, the name of the country will be used as the main keyword (e.g. France).

Now, remember that this is a thorough article. In that regard, you will have to cover different aspects of the topic. It is only expected that you will talk about various French cities (e.g. Paris, Lion, Marseille), French cuisine (croissant), French history (Napoleon) and so on.

Given that you used the broadest keyword possible, you will have to use a broad array of LSI keywords just so that Google can notice you. If the topic was narrow, you would’ve used only a handful of LSIs.

We have to clarify this a bit more.

With the LSI concept, Google is able to determine relations between the keywords. That being said, a search engine is able to determine how relevant a certain phrase is to the article and how often it should repeat itself.

For example, in an article about American presidents, you will use Abraham Lincoln more frequently than Gerald Ford. However, both of them are necessary for Google to perceive the article as relevant.

Basically, LSI helps establish what is normal and what is not normal within a text.

Using LSI keywords to your advantage

Now, here is the question you’ve all been waiting for.

How can you use this knowledge to your advantage and create content which is more likely to rank on the first page of Google?

We got a few tips for you!

  • Write naturally

First and foremost, LSI keywords are used to determine what is natural and what is not. Best thing you can do is to write an article without thinking about keywords and their frequency.

  • Use synonyms

Besides related phrases, synonyms are also important. In the end, if you are writing a natural copy, it is expected that you will use a few synonyms for your most frequently used words.

  • Think about the topic beforehand

Google uses your copy to determine the real intent behind it. For example, if I used word “France” a few more times, it could’ve misled Google to think that this article revolves around it. By considering everything in advance, you are able to make a battle plan and determine which few keywords should have priority.

  • Check out the top results

No matter how hard you try, you may still forget a few keywords. This can be easily prevented if you go and check top 10 results in Google. In the end, if they managed to reach the first page, they are probably doing something good.

  • Going back to the article

Naturally, you will read the article after you’ve finished it. But, you will also need to focus on your LSI. It is common for an author to forget a few things. So, go back to the article, read it again and make sure to add a few phrases that you’ve missed.


When it comes to LSI keywords, these are all the tips you need. However, try not to overdo it. Google expects naturally written content. This is why LSI concept was introduced in the first place.

Basically, as long as you write a thorough, informative article, you should be fine.
