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

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

  • Example 1: If you are writing an article on Cars, keywords including 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 similar 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 (latent semantic indexing) 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 words for “Apple”.

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.

If you collect more LSI keyword lists from various tools, there are chances of having repeated phrase keywords in the listings. Therefore, you need to remove those duplicated keywords.

2. Place the keyword naturally

It is too dangerous. Pick relevant phrases that are similar 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.
