What Are LSI Keywords?

LSI keywords (Latent Semantic Indexing) are keywords semantically related to your content main keyword. 

When you come across the word for the first time it sounds like something new and not for me type.

But, that’s not the fact.

LSI is a very simple concept to understand and we all are using the LSI keywords in our content without even knowing about it.

LSI Keywords 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 somehow related to your keyword.

For example, if you have a post on “Windows“ operating system, your post should logically have the name of “Bill Gates“, “Microsoft“, “Windows 7”,
Windows 7” and so on.

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

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

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

LSI Keywords Vs. Long-Tail Keywords

There are some differences between LSI Keywords and Long-Tail Keywords.

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

The main 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 more related keywords.

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

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

Why Does Google Use LSI Keywords?

Once upon a time when the only measure Google had for relevancy of a page to a given search query was keyword density.

As we all know, keyword density was horribly abused and also spammed.

So, Google moved away from this practice and began looking at LSI keywords.

The main reason was:

A content about ‘Apple computers’ will likely contain a host of other words that are related to Apple computers (such as ‘apple stores’, ‘apple iphone 5’, ‘apple new iPad’, ‘apple stock price’, ‘discount computers’).

On the other hand, a keyword-stuffed page about ‘Apple computers’ will contain just that one keyword.

So, LSI keywords provided Google with a way to differentiate the sheep from the goats.

But there’s another reason why Google started using LSI keywords.

Latent Semantic Indexing helps Google to better understand the meaning of any search query and the meaning of any web page.

And that  allows Google to improve the exact match between what people search for and what they find in the search results.

Hummingbird and LSI Keywords

Hummingbird update (introduced in August of 2013) was targeted towards the misuse of keywords. It was designed on the basis of the semantic algorithm.

The Hummingbird algorithm focuses on synonyms and improves Google’s ability to understand the context of any web page.

Hummingbird algorithm is particularly interested in searcher intent.

Whereas previous algorithms was focused on individual words in a search query, Hummingbird looks at every word within the context of the whole search query.

In other words, the Hummingbird algorithm is trying to understand the meaning – that helps Google match user intent with search results.

Benefits of Using LSI Keywords:

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

Here are the few key benefits of having LSI keywords in your content:

1. Prevents Content From Being Labelled as Spam

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

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

This also differentiates your content from spam content.

2. Decrease in Bounce Rates:

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

Let’s have a look at this example:

There are 2 articles nearly at the same term “Notebook”.

But essentially they are about:

Notebook, the movie (2004) and Notebook PCs

Here Google takes your LSI keywords like “romantic film”, “MTV movie awards” and “deleted scenes” to distinguish the first article from the second.

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

3. Increase On-Page Time Spent By Visitors

It helps to stay visitors on your site.

LSI keywords make the flow of content natural and meaningful and thus attract readers.

4. Improve Search Engine Rankings

It helps you to rank better and higher for related searches.

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

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

5. Increase Sales

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

For example, Amazon.com makes 57% of sales from keywords outside of the “popular” terms.

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