Everyone, in the SEO world, is talking about LSI keywords and their impact on the rankings of a website. Frankly, the topic has created quite a buzz among SEO professionals and other website owners as well.
While many SEO professionals have already started utilizing the LSI keywords as a part of their SEO strategy, others have no idea about their significance whatsoever. For the latter category, we have decided to share our thoughts on LSI keywords and how one can use them to achieve significant results for his/her website.
What is Latent Semantic Indexing (LSI)?
Before moving towards LSI keywords, let’s first understand, how these keywords actually came to existence. LSI keyword is a concept which has its roots in the 80’s computer technology, the Latent Semantic Indexing (LSI).
The technology was developed to help a computer understand the overall context of a document by finding correlations between different phrases used in the document itself. It helps a computer to read and understand a text document in the same way a human does.
How Do Search Engines Use the Concept of LSI?
So, how do search engines use LSI to improve their search results? Basically, search engines have started to focus on understanding the overall context of a content to provide better and more accurate results to a user’s search queries.
LSI helps a search engine to understand the exact meaning of your content by finding relations between different phrases (written in the document) with the target keywords. As a result, the search engine provides users with better results based on their queries.
What are LSI Keywords?
Now that you know what LSI is, let’s take a look at the LSI keywords. As per the official definition, LSI keywords are the words or phrases which are related to your target keywords. However, many people have started to misinterpret LSI keywords as synonyms too, which is not the case at all.
While LSI keywords could have a certain relationship to the target keyword, they never have the exact same meaning. If anything, LSI keywords are far away from synonyms. For instance, the keyword ‘games’ can have LSI keywords like ‘computer games’ or ‘outdoor games’, but the word ‘tournament’ does not fall under the category of LSI keywords.
Since a word can have a variety of meanings, LSI keywords help the search engine to figure out your intent and the context of your content.
For instance, if your target keyword is ‘Pie’, then there are two possible cases.
- You have written about the dessert ‘Pie’, and therefore your blog can include keywords like ‘apple’, ‘bluebery’, ‘chocolate’, ’banana’, etc., the different kinds of pie.
- You have written about the latest Android version ‘Pie’, and therefore your blog is more likely to have words like ‘Android’, ‘smartphones’, ‘Android Pie’, ‘Android 9.0’ etc., the words that relate to the Android version ‘Pie’.
As a result, it becomes easier for the search engine to understand the context of your content, and eventually provide the user with highly accurate search results.
Why do Search Engines Need LSI Keywords?
For many years, keyword density was one of the major factors to influence the rankings of a web page. Keyword density is the percentage of the target keywords used in a blog to the total number of blogs. For instance, a blog with a word length of 1000 in which the target keyword appears 20 times, the keyword density would be 2.
However, the strategy soon turned into a curse for the search engine as many website owners started to perform unnecessary ‘keyword stuffing’ with a sole purpose to increase the keyword density. Despite having all the target keywords, most of the web pages had completely irrelevant content.
To overcome this scenario, Google decided to pay attention towards understanding the actual meaning of the content rather than relying on the keyword density. It is when LSI keywords came into the picture.
Since LSI keywords help the search engine to understand the actual meaning of the content, using them in your content eventually increases the odds for your web page to rank higher on the Search Engine Result Page (SERP).
Keyword density has become a thing of the past. So, if you are still relying on keyword stuffing to improve the rankings, you are wrong. Unnecessary keyword stuffing not only affects the rankings of your website but can also lead to a Google Penalty.
So, avoid stuffing your web pages with target keywords and use LSI keywords instead. However, make sure to only add keywords which have a certain correlation to the target keyword as using irrelevant LSI keywords is also a bad SEO practice which can easily lower the rankings.
How to Find LSI Keywords?
Now, that you are familiar with the LSI keywords, let’s move towards the process of finding them. When it comes to finding LSI keywords, you can follow one of the following four approaches.
Through Search Engines
Using the search engine itself is the easiest way to find a list of LSI keywords for your target keyword. Simply type down your target keyword into the search bar and wait for Google to drop down a list of related search queries.
Here’s a list of LSI Keywords for ‘mobile application.
Here you can see that typing mobile application provides a variety of LSI keywords which you can scribble down in your content to make it easy for Google to understand its context.
Similarly, you can also use the related searches section to find other LSI keywords for your search query.
While you can use the Google Search option to find a list of LSI keywords, they provide an insight into the average search volume and competition of the keywords. Furthermore, the keywords generated via related search section can vary from location to location.
Therefore, to find more accurate LSI keywords we recommend using tools like Google keyword planner.
Google Keyword Planner
Google keyword planner is one of the most convenient tools using which you can find LSI keywords for a particular search query. If you already have a Google AdWord account, you can easily use the keyword planner under the tools section.
