How to find LSI Keywords for better ranking in 2019?

Before going to that, we need to know a few points about LSI Keywords.

What are LSI Keywords?

What is LSI? LSI Keywords means Latent Semantic Indexing. This is the concept used to determine the relationship between terms and concepts in content.

LSI keywords definition is

These are the related keywords to the main keyword. Most of the search engines understand the link between the entire web content.

They are the similar or closely related words/phrases of the targeted primary keyword for the specific keyword. It increases search relevancy. Some LSI Words are given below for easy understanding.


  • Example 1: If you are writing an article on Cars, include keywords like Engine, Machine, Wheels, Interior, Mercedes, Audi, and KMPH then through this Google will understand that you are writing an article on Cars (Vehicle).
  • Example 2: If you are focusing on “online mobile” keywords, “Mobile prices”, “online mobile reviews” “mobile tech specification” can be the related keywords to the root keywords.
  • Example 3: The LSI makes better sense to the single keyword. If you take the keyword “Apple”, how does it differentiate whether Apple is a fruit, Apple is a brand or Apple is the name of any pet? Here the search engines search for LSI words for their understanding. If they find words like Fruit, taste, and flavor in the content, then it would be easy to understand the article about Apple Fruit. Here Fruit, taste and flavor words are LSI word for “Apple”.

In Old-school SEO concepts, Keyword stuffing is more popular to rank the pages in Search engine. Now Google developed and introduced this LSI keywords usage concept to provide more relevancies for sites.


Difference between

LSI Keywords vs Long tail Keywords

There is a huge difference between LSI and Long tail keywords.

  • The major difference between LSI Keywords vs Long tail keywords is, LSI Keywords broaden the search with related keywords, but Longtail Keywords narrow down the scope of a search.
  • Long tail keywords are the lengthened version of a keyword combination used by searchers.
  • Long tail keywords show searchers intentions like “top”, “How”, “what”, “Why”, etc.
  • By adding long tail keywords, the optimized content gets better rankings for those exact search terms, and you will have a boost in your website traffic.
  • LSI Keywords helps search engines to understand page content.

Where to Use LSI Keywords?

These LSI keywords are beneficial for users and for Search engines if you are using properly.

How to Use LSI Keywords for a better SEO?

This is the biggest secret in the SEO industry. Most of the bloggers and marketers are inserting the keywords into the content without any strategy.

The ranking of blog/blog post is depended on the placement of LSI keywords. If you are not using correctly, your ranking will break. You can use 2 to 3 LSI keywords per 100 words in the article.

Here I am providing few tips to make better SEO

1. Choosing a good Keyword

The LSI mentioned above tools generate LSI keywords based on Search engine algorithms. So most of the keywords are not related to the primary or target keyword.

You need to filter out useless keywords from the list. That means, pick the relevant keywords.

If you collect more LSI keywords lists from various tools, there are chances to having repeated phrase keywords in the listings.

Therefore, you need to remove those duplicated keywords.

Here the Google chrome addon – remove duplicate extension is useful.

2. Place the keyword naturally

Placing the relevant and good LSI keyword within the content is very important.

If you put it unnaturally, it may be harmful to your site SEO.

Do not add all generated LSI KWs in the single article.

It is too dangerous.

Pick relevant phrases from the list; place it naturally within the content.

Sprinkle the keywords into your content in a meaningful way.

If you add in this way, your blog post gets better ranking.

3. Choose and add more targeted positions

Use the keywords in following targeted locations without missing.

These places appear natural and give better readability to the reader. places to add lsi keywords

Final Words on this Post

Using LSI Keywords is an art of blogging. If you use it as SEO friendly and in a natural manner, the results will be surprising.

Using more these keywords in the single content leads to content spamming.

The content having the same meaning or synonyms becomes readable content for both readers and Search engines.

Are you using LSI keywords in your articles?

If yes, mention the tool you are using in the comment section for more discussion.
