How to Find LSI Keywords and Smartly Implement Them for SEO

LSI. Sounds like a new term? Keep on rolling. Latent Semantic Indexing (LSI) is a part of the Google algorithm. Knowing about it and implementing it as a part of your SEO strategy is crucial. This post presents you the concept in an easily understandable way.

What are LSI keywords?

Definition, “LSI keywords (also known as semantic keywords) are the related keywords to the main keyword. Many of the search engines like Google use it to decide the link between different entities of the web content.” It helps Google get the meaning of the written content.

It also deals with search relevancy. Including LSI keywords with main keywords is SEO friendly. In earlier days, search engines used exact search query to get results. With this, search engines were not giving accurate results. Now, search engines analyze the meanings of the search queries. The content synonymically linked to the search query, are also returned. Google mainly carried out this to fight spammers trying to cheat the search engine by using keyword stuffing.

LSI algorithm tracks down spun content

Article spinning softwares have no capacity to understand the article and rewrite them. Search engines do.

The main power of Latent Semantic Indexing is its ability to expect related words while dealing with a particular topic. When it comes across unrelated words to the topic. In those cases, it considers the content is spun. The idea of LSI may be not clear to you now, keep on reading…

What are LSI keywords?

LSI or Latent Semantic Indexing is an alternative term for synonyms or similar words used by Google. Have you ever wondered how Google and other search engines differentiate between homonyms (same word with different meanings)?

Take an example. The term “PS” has different meanings in Google like PlayStation, Photoshop, and so on. Google gets results based on the keywords you have used after the term “PS”. Consider an example, where I search for “ps image size”. Google came to know the term “ps” in this context refers to Photoshop. Because I have used “image size” in front of it. Now Google searches all the content containing the terms Photoshop and image size, both.

It also looks at web pages containing the term “picture size”. Because “image” is nothing but “picture”. They both are semantically related. By this, we can say, Google looks at the meaning of the search query.

By doing this, it can get what the user is trying to search. This is a part of Google’s LSI algorithm.

Another Example for LSI keywords

You may have noticed this. Google highlights the synonyms in SERPs. Let me take an example. Search for “ps picture size”. Google highlights the words “picture, photo, image”. These Synonyms are LSI keywords in Google vocabulary. Sometimes the synonyms highlighted in SERPs are also called Synonymous LSI Keywords (sLSI). Now you got a clear idea what is LSI.

How to Find LSI keywords?

You now know about LSI keywords. They are the related keywords for a particular keyword. There are several LSI keyword tools. Among them, the Google search is an excellent tool, all that matters is, you have to learn how to use it. Here’s the simplest way. You can find LSI keywords from search suggestions. And also from related searches at the bottom of the SERPs.

These Related keywords are also called Related LSI Keywords (rLSI). Apart from Google search, you can also use the Google Keyword Planner. The goal is to note all the synonyms to your main focus keyword.

How to Implement LSI keywords for SEO?

Let me take an example. You are writing an article on Complete Guide to Recover From Google Panda Update. Your prime keyword would be “Recover from Google Panda Update”. LSI keywords are “Rescue your site from Google Panda Update, Recover from Google Panda effect, etc.”

After you write a post on this, make sure you include related terms like effect, SEO, Penguin Update. If you have a title – “Recover from Panda”, and LSI keywords like SEO, update, etc. in the post, it acts as a content relevancy signal. Once you put terms like “animal, attack, white bear, etc.” Google thinks that your post is about recovering from Panda animal attack. Avoid repetition of the same keyword over and over.

As you can see in the above screenshot, Ankit in his post – Blogging Tips, has made clever use of LSI keywords for targeting the main keyword – “Blogging tips for beginners”.

Where to include LSI keywords?

LSI and other keywords follow some basic rules. You can include LSI keywords anywhere in the article. In,

• title tag
• header tags
• permalinks
• anchor texts
• beginning paragraph
• ending paragraph

Even, stuffing the LSI keywords all through the blog post smells spammy. Google has grown beyond what you think. Google may punish you for keyword stuffing. “Using LSI keywords is SEO-friendly and natural. It is better than using the same keyword often in your blog post”. As I said before, use related keywords only to signal content relevancy. Also read:
