Use “Latent Semantic Indexing” or LSI keywords in your content marketing strategy to improve your search engine rankings – But How?

In this blog, explore how to use LSI keywords to boost SEO.

What Exactly Are LSI Keywords?

Latent Semantic Indexing keywords are related to the main keyword in context but not synonymous due to slight differences in meaning.

Latent Semantic Indexing (LSI) is a set of related keywords used by search engines to understand a webpage’s content. By finding an LSI keyword match, you can use these keywords to increase your SEO and get more targeted visitors to your website.

Using the primary keyword “project management software,” some LSI keywords that you can use to expand your search:

  • Small business management software
  • Document management software
  • Project tracking software
  • Task management software free

It is essential to understand the difference between LSI keywords and long-tail keywords for more clarity.

An LSI (latent semantic indexing) is a keyword that expands upon the main keyword. It uses either similar or completely different words to convey the same meaning. In the example sentence, “pastry classes” is an LSI of “baking classes,” while “best baking classes near me” is a long-tail keyword that delivers results to searchers looking for pastry-related classes.

Importance of LSI Keywords in SEO

Early on, Google used to focus only on the search term. Search engines couldn’t distinguish between keyword-stuffed content and meaningful material, so search results were often inadequate. You might also get irrelevant answers or plain junk.

For example, if you were looking for information about cars and performed a search using the keyword “cars,” you may have seen the following mix of results:

  • It will display Vehicle details, repair tips, and information about renting 
  • Renting to own automobiles.
  • Animated Disney movie Cars
  • Cars Indian Association for Sports, India

Over time, search engine algorithms have grown more sophisticated, enabling them to uncover relationships between primary and secondary keywords using the Latent Semantic Analysis (LSA) process. It has enabled search engines to interpret content that resembles how human beings do.

When writing an article, use LSI keywords that describe the subject of your content, so search engines will easily understand what your piece is about. For example, if you are writing a piece about baking, use words such as “flour,” “baking powder,” “essence,” “flavor,” and “used.” If you are writing a piece about The Great Indian Bake Off, use words such as “Bake-off, “baking shows”, or “animated picture Bake-off .”

How Do You Find LSI Keywords?

The most important part of your SEO strategy is using LSI keywords to make your content appealing to search engines. Let’s take a look at how you can do this.

  • Google Autocomplete

You can find LSI keywords by using the Google Search Autocomplete feature. Whenever you type a search query into Google, it makes a few relevant suggestions, often strong LSI keywords.

For example, enter the following query into Google: digital marketing. The additional words you entered turn the main keyword from digital marketing into an LSI keyword. For example, Google displays LSI keywords like digital marketing definition, digital marketing examples, digital marketing tips, etc.

Alternatively, you can find related search terms in the lower portion of the results page under the heading “Searches related to digital marketing.” Different related search terms will appear depending on their popularity, relevance, and geographical location.

  • Free Google Keyword Planner 

You can use the keyword planner to research LSI keywords. The tool suggests hundreds of search phrases related to your topic.

To get started, log into your AdWords account and select “Find Keywords.” Enter your search term in the “Search for new keywords using a phrase, website, or category” option. Then select the most relevant LSI keywords for your topic.

You can use other SEO and keyword research tools like Moz, Ahrefs, and SEMRush. These tools are essentially LSI keyword generators that can be used to create a list of long-tail keywords. Many of them get confused about selecting the right keywords for their content. Our article on keywords for beginners is one such blog that can help you understand search intent on keywords.

  • LSI Keywords Assistant

Several LSI keyword research tools are available online, including LSI Graph. You need to type your search query and hit the Generate button. 

A free tool called Keysearch searches for one-, two-, and three-word alternatives for a keyword. The advanced version includes detailed analytics, the ability to uncover your competitors’ keywords, and SEO content assistance.

How to Use LSI Keywords in Your Content?

  • Optimize Your Title Tags with LSI Keywords

Generally, long-tail keywords (LSIs) are often variants of your primary keyword. For example, “SEO tips” and “SEO tips and tricks” are long-tail versions of one another. Use the LSI in your title to rank for both keywords simultaneously.

  • Use LSI keywords in your meta descriptions

Consider using LSI keywords in your meta description to increase the likelihood that your website appears in search results for a particular keyword. However, do not overstuff keywords in your meta description to ensure good readability. LSI keywords play a significant role in meta tags

  • Use LSI keyword-based Alt tags in your images

All of your site’s images should have alt tags. Include some of the site’s LSI keywords in those alt tags. Naturally, the images you include on the site should be somewhat related to your LSI keywords.

  • Include LSI keywords in the first half of the content

Earlier, when a keyword appears on a web page, it is regarded as more important. Your primary keyword should appear in the first paragraph of your article. The important LSI keywords should appear within the first 50% of your article body. You need to reorganize your article structure to place these words closer to the beginning of your content.

  • Please include LSI keywords in headings

H1 and H2 tags, which help categorize web pages and give them an outline, should include keywords that are both important to your page and closely associated with your content.

When you find a keyword that is relevant but doesn’t fit in your existing article, you may create a new section in your article centered on that keyword.

  • Use semantically related keywords in your anchor texts

Optimizing your anchor texts for a single keyword may adversely affect your SEO.

For example, suppose you promote your Web design business through guest posts on different sites and always use the keyword “Web design company” to link back to your site. In that case, it will be challenging to gain rankings for other related keywords.

Referrals from reputable links make a positive impact on SEO. For example, we used “web development company” and “web design service” in our anchors to create more natural links.

  • Pay attention to context and readability

Using LSI keywords without context is a mistake. Contextualizing LSI keywords can help quality content rank better, but the lack of a contextual framework for these words will leave the post with a lower quality score and little weight.

When you optimize an article using LSI keywords, read it over carefully. If the placement of a keyword in a sentence does not fit correctly, remove the keyword. Rewrite the sentence or write a new sentence or paragraph if necessary.

  • Use LSI keywords in your PPC campaigns

Finally, you can also include LSI keywords in your PPC ads. It will increase the chances of your ads showing up in the search results, but it may take some time to produce the desired results of your LSI keyword strategy.

Factors such as monthly searches, keyword competition, and website authority will determine how long it takes to see results from using LSI keywords.


Keywords are an integral part of your search engine optimization efforts. Optimizing SEO content with LSI keywords will improve your rankings in search engines. From your main marketing tactics to your pay-per-click campaigns, you can use LSI keywords in almost every aspect of marketing content.
