LSI keywords

Are you one of them who is underestimating the importance of LSI Keywords while writing post or doing SEO? If yes, then you’re actually making mistake and missing out great opportunities of ranking high in the SERPs.

If you’re in SEO world then you may be have some idea about LSI Keywords. Nowadays everyone in the SEO Market like Neil Patel and Brian Dean is talking about LSI Keywords and they are yelling out to use these LSI Keywords for our content and pages.

As Google loves LSI Keywords and it also rewards the website that generally use them and LSI Keywords really helps in ranking higher on the SERPs easily without putting much effort. But before jumping to the conclusion let’s understand what LSI Keywords actually are?

In this guide we are going to tell you- What are LSI Keywords & The Importance Of LSI Keywords & how they can help you to rank in 2019. Let’s start: 

What Are LSI Keywords?

The LSI keywords (Latent Semantic Indexing) are basically  those keywords that semantically related to your main keywords. Over the years, Google has collected petabytes of data to improve user search results and provide better user experience to its users.. By analysing this data, Google was able to determine the relationships between the keywords and show the relevant content to the users easily.

In a simple way I can say that it’s a way the search engine decides which pages are semantically related to a given search query.

If you wonder what LSI means, it’s a latent semantic indexing. This strange term is actually the mathematical formula that Google uses to determine the relationship between keywords that we generally type on the  google search box.

LSI keywords can take many different forms. Sometimes they are synonymous. Sometimes they are shortcuts. Most of the time, they find enough sites in a similar keyword to relate them to each other.

Google is smart enough to easily realize that the keyword “search engine optimization” is actually the same as “SEO”. They are exactly the same and therefore have a very close relationship. This is probably a very obvious example, but above all it is not so obvious.

Here is another example:

Let’s say your blog post  is about Apple.

How does Google know if you mean the fruit or the company let find out how Google do it?

Search for LSI keywords:

If your page contains the words “baked apple”, “red apple”, “green apple”, “apple nutrition”, “fuji apple”, “honey crunchy apple”, “apple food”, your page probably deals about fruits

If your page contains the words: “itunes”, “apple hulu”, “apple news”, “apple stores”, “apple iphone 5”, “apple new ipad”, “apple stock price”, “discount computer”, The page is more likely on Apple computers.

Sometimes, on almost any web page, a keyword or phrase appears that refers to a particular keyword and you will not even notice it. There can be many examples of LSI keywords and I hope you can now have fair idea about LSI Keywords.

Most probably you might be thinking why Google Uses LSI Keywords? Let’s find out the reasons together.

Why Does Google Use LSI Keywords In Its Algorithm?

There was a time right when Google only measure a relevance of page simply by using the Keyword Density and that’s blogs and website stuffed more and keywords in order to rank higher in the SERPs.

As you all may know that Keyword Density was abused and spammed at that time. And that the reason why Google moved away the Keyword Density Relevancy and introduce the most effective method called LSI Keywords.

And that’s reason why google moved right away from the keyword density and began looking for the LSI Keywords in blog and website for every search.

Like if you have a page about SEO then that is more likely to contain words and phrases like Search Engine Optimization, Keyword Research, On-Page Seo and Off-Page SEO, Backlinks and more. So Google simply find out what your page is all about simply looking after the LSI keyword in your post and pages.

And if you’re dumb and just use keyword like (SEO) then Google will find out and spam your page or website for the Keyword Stuffing.

But there is also other reason why Google use this LSI (Latent Semantic Indexing) Keywords. Generally Google uses this LSI keywords because it mainly help Google in understanding the meaning of a Search Query and the meaning of the web page too.

And this simply allows Google to easily improve the match right between what people search and what they are actually getting in the Search Engine Results Pages.

What about Hummingbird VS LSI Keywords?

Back in August 2013, Google generally introduced the Hummingbird Algorithm and sometime they also called it as a semantic algorithm. The work of semantic algorithm was generally focused on the Synonymus along with enhancing the Google’s ability to simply understand the context of a web page as well.

We can simply say Hummingbird is focused and interested in Searcher Intent. But the previous Google Algorithm was focused right on individual words right in the search query. Here the Hummingbird looks at each word in the context of the entire search query. In other words we can just say that Hummingbird algorithm is simply trying to understand the meaning and it also helps Google in order to match the users search intent.
