What Are LSI Keywords (And Do They Help with SEO in 2023?)

In this post, I’m going to break down EVERYTHING you need to know about LSI Keywords.

What they are.

Why they’re important.

And whether or not they help with SEO.

In the end, I’ll give you 3 practical examples to effectively include them in your content.

In short, if you are willing to optimize your content for search engines and drive more organic traffic, this post is for you.

Let’s dive right in.

What Are LSI Keywords?

LSI keywords or latent semantic index based keywords are the word phrases that are related to your primary keyword.

These can sometimes be synonyms, substitutions, and related words.

But a major of the time you have to take care to include words in your content that are sentimentally and logically related to your keyword.

For example, if you have a post on “Windows“, your post should logically have “Bill Gates“, “Microsoft“, “Windows 7” and so on as mentions.

These words or LSI keywords are what will help Google differentiate your post from the searches related to “luxury windows locks” or “Wooden windows grills”.

In the above image, you can clearly see what could be the potential LSI keywords when you are writing a post on “windows”.

You can also get a couple of LSI keywords from the footer of Google search results that is called “Searches related to…

LSI Keywords Vs. Long-Tail Keywords

Is there any difference between LSI Keywords and Long-Tail Keywords?


LSI keywords do not exactly mean long tail keywords but are somewhat similar to them.

The key difference between LSI keywords and long tail keywords is, long tail keywords narrow down the scope of a search whereas LSI keywords broaden the scope with related keywords.

You can read my article on long tail keywords to further broaden your views.

Search engines use LSI keywords to check how deeply you have knowledge on the written topic and also rank your page for related terms.

That is why you have organic traffic to your blog posts from keyword phrases that you haven’t ever targeted or even heard before.

Benefits of Using LSI Keywords:

LSI keywords have so many advantages as far as SEO and user experience is concerned.

Here are the perks of having LSI keywords in your content:

1. Prevents Your Content From Being Labelled as Spam:

LSI keywords prevent your content from being marked spam in the eyes of search engines.

Having a varied mention of keyword phrases that are semantically related to your primary keywords increases your content’s credibility.

This also differentiates your content from spun content.

2. Decrease in Bounce Rates:

LSI keywords help you in reducing bounce rates by preventing your site from ranking for the wrong terms.

Take a look at this example:

There are 2 articles targeted for nearly same term “Notebook”.

But essentially they are about:

Notebook, the movie (2014) and Notebook PCs

Here Google takes your LSI keywords like “romantic drama film”, “MTV movie awards” and “deleted scenes” to distinguish the first article from the second (that has words like “engineered PCs ideal for home”, Accutype keyboard, etc.).

This way a movie buff doesn’t land on Lenovo site and thus no bounce rates.

See how LSI keywords change when you change topics!

3. Increase On-Page Time Spent By Visitors:

It helps to retain visitors on your site.

LSI keywords make the flow of content natural and meaningful.

This gives your readers a peaceful environment without making it feel keyword stuffed.

4. Improve Search Engine Rankings:

It helps you to rank better and for related searches.

Google bots automatically crawl your site and make a perception about what your article is.

Now they use LSI criteria to rank your site for semantically related searches no matter what your target keyword is.

5. Improve Blog Authority:

More rankings = more click through rates = more authority of your blog.

6. Increase Sales:

LSI keywords are also like long tail keywords and hence you can rank higher without less competition.

For example, Amazon records a hefty 57% of all sales through keywords that are long tail and LSI versions of the primary keyword.

This is only because there is less competition and exact buyer intent down there in the LSI zone.

How To Use LSI Keywords To Rank Your Content Higher?

Now that you have gotten all the valuable LSI keywords, the next million dollar question is how to use them?

Most bloggers that I have come across either inserts the LSI keywords into their content without any strategy or mess up their primary keyword with LSI keywords.

However, using LSI keywords correctly in your content has an importance of its own.

Correct placement of LSI keywords can make or break the rankings and credibility of a post.

Here are some tips to make the most out of your LSI keywords.

1. Choose The Right Keyword:

Most LSI keyword tools generate related keywords based on a set of an algorithm.

They aren’t human produced hence they lack that personal touch.

Moreover, you will find out that in each list of generated keyword, there are phrases that aren’t related to your primary keyword or are too broadly related.

These terms must be removed or filtered out.

Since having phrases that have nothing to do with the topic you write is also detrimental for your SEO.

In the above screenshot, if you are writing an article about backpack for dogs, and you chose the keyword, backpack for cats, as well because it was suggested, and then it will harm your SEO.

It will not remain relevant for users, and search engines will flag your article.

TIP: If you use more than one tool to generate LSI keywords then chances are you might have some of the keywords twice or more.

In that case, an easy hack to remove duplicate keywords is to copy all the keywords onto a Google spreadsheet and run the remove duplicates extension. This will crop out any traces of duplicate keywords.

2. Place It Naturally:

Having so many LSI keywords might be a disadvantage to some because you have to place them naturally and not inject them anywhere and everywhere.

You need not use all of the generated keywords in every single article.

Only choose the ones that have value for your content.

Brian Dean also suggests sprinkling your LSI keywords into your content in a way that they add meaning and value to your blog post.

3. Target More Positions:

You can also use your LSI keywords in your post title, as a question in the conclusion and also as anchor text to an internal link.

You can also use them in title tags, permalinks and most importantly in introduction and conclusion section of your blog posts.

This appears natural and gives a flow to your post.

Neil Patel has mastered this skill. Check out how he leverages the conclusion section to insert a few LSI keywords as well as interact with the audience.

You will find that his copy appears completely natural in terms of relevancy.

Over To You:

With this guide to using LSI keywords in your content strategy, I hope you will write better content.

Most importantly, write content that is relevant and meaningful to your readers.

Having words with the same meaning or synonyms not only makes your content light but also makes it smooth for reading.

Did you notice how I used the phrase “Words with same meanings or synonyms” as an LSI keyword for my content?

That’s the trick.

Have you used LSI keywords in your articles?

Do you know a tool that is wonderful but I haven’t mentioned here?
