Semantics â€“ now that’s a phrase that could make SEO experts stop and take notice. Make it latent semantic indexing (LSI), and you’ve got a head turner and a showstopper combined into one. If you still wish to be overwhelmed, check out Stanford’s take on LSI(a mathematician’s delight, an SEO expert’s nightmare).
Or, you could take my word, and understand that in the context of SEO, LSI is a methodology used by search engines to find content that matches well with the search intent of the user. For search engines, LSI is their way to understand which content is more contextually relevant to the user. For SEO experts, LSI is their way to optimize their content for search engine. Doing so:
- You will be able to optimize your content in a way that makes it easier for audiences to comprehend it.
- Search engines will show you their love for doing so.
Let’s tell you more on how you can boost your SEO by using latent semantic indexing keywords.
A Quick Start
To understand semantic keywords better, conduct a Google search for your most important keyword. For instance, I did it for ‘how to roast coffee’ and found these ‘suggestions’ from Google.
Notice how these are very closely related to the main keyword. It’s clear; Google thinks these terms are close related to your search term. It’s all you need; now use your intuition and pick up the most suitable keywords from these, and use them naturally and contextually in your content.
Use Google Keyword Planner for Semantic Keyword Ideas
Your next option: Google’s very own Keyword Planner. If you have a Google Adwords account (create one, it’s easy enough), go to the Keyword Planner tool, and select “search for new keywords using a phrase, website, or category”. Key in the required information, and click on the Get Ideas button.
Not only does this give you a comprehensive list of semantic keywords, but also tells you their search volumes.
Use LSI Graph to Generate More Semantically linked Keywords
If you need a wider selection set, use the LSI Graph tool. It’s free to use, super easy, and super quick. Look how I repeated my search for my focus keyword ‘how to roast coffee’ and found so many related keywords. Not only does this prove vital in planning content around the core topic, but also makes sure that my post is considered highly relevant for my target keyword by Google.
Use SEMRush for Detailed LSI Keyword Research
Still not satisfied? Use SEMRush’s Keyword Research tool. Key in your phrase, go to Phrase Match Keywords section, and click on Full Report. In this report, you get all the info you need to pick the best LSI keywords for your target keyword.
How To Use My Artillery of LSI Keywords?
Now that you have dozens of potential LSI keywords for you target keyword, you need to optimize your post to include most of these in a contextualized manner. Some best practices to follow:
- Look to use them a maximum of 1-2 time (without making the content sound superfluous)
- Insert them in the H1 tags of your web content
- Break down content into small sections (60-100 words) to include related but non-overlapping keywords.
- Make sure your page’s content is still 100% relevant to your target keyword.
Understand Search Intent Of Users to Shortlist the Most Relevant LSI Keywords
Ask yourself â€“ what are the types of queries my audiences are using to find my content on Google? The analysis of these queries will help you understand their intent, and that makes the selection of relevant LSI keywords possible.
In my example, I am certain that the intent is informational. My most relevant audiences are likely to use my roasting methods immediately. My choice of keywords has to be in sync with this analysis. So, I will only choose keywords that Google is also likely to consider as having relevance for informational intent.
With this information, I have been able to rule out quite a few keywords.
From the remaining ones, I’d do the basic volume search, find keywords that are a good balance of search volumes and low competition. In this manner, the idea is to shortlist and drill down to the most relevant LSI keywords.
LSI Red Flags to Avoid
- Don’t stuff meta keyword tags with dozens of LSI keywords
- Don’t stuff useless and unrelated LSI keywords
- Don’t switch the contents of the page once it’s been indexed
- Don’t stuff your meta description with keywords
The secret sauce of LSI success is to first find the theme for your content, and bolster it with carefully selected semantically related keywords. Finding lists of LSI keywords is not hard; however, you need to invest your intuition as well as careful analysis in choosing the ones to include in your content.
