With the concept of the World Wide Web, developed the concept of a semantic web. The semantic web aims to prepare content that can be understood by humans as well as machine readers like search engines and web crawlers.

What Latent Semantic Indexing (LSI) Is 

LSI, or Latent Semantic Indexing, is a natural-language processing technique that was created in the 1980s for machine readers to understand human keywords. Without getting into too much into technical details, the way LSI works is pretty straightforward, and best demonstrated with an example.

 Let’s get back to the example of “mouse”. If you search for “mouse” in Google, Google will look up different LSI keywords that relate to “mouse”. If Google finds words such as rodent, animal or pet – it will assume that you are looking for a rodent called a mouse. On the other hand, if it finds words such as technology, pointer, and computer – it will think that you’re looking for a mouse, the computer accessory.

LSI keywords do not necessarily mean synonyms. Rather it refers to keywords that are semantically related to your target (or focus) keyword. In other words, your focus keyword and LSI keywords must share the same context.

Finding the Right LSI Keywords

LSI keywords are important for your website, as they ensure that your web page is more relevant to people’s searches, and is displayed more often. This means that it will drive more traffic to your website. So it’s important to choose your LSI keywords carefully so that you get more visitors to your website and they are happy with the content they find.

Implementing LSI Keywords in Your Content

Finding the right LSI keywords for your website content is not enough. You should also know how to use them. You need to insert them in your content naturally and subtly, so they do not seem irrelevant and out of place. Keeping this in mind, there are several ways you can fit in your LSI keywords into your web page.

Write a Meta-Description

Generally, you use your focus keyword in the title. But you can also give your content a meta-description, which basically describes the entirety of your web page in a few short sentences. Using LSI keywords in your meta-description makes search engines give it a priority, and ranks it higher.

Introduction and Conclusion

Your introduction and conclusion are of the utmost importance when it comes to SEO. Using relevant keywords in your article makes your content interesting, reinforces your message and also drives traffic to your page.

Don’t Forget About Images

If your web page content contains images, you can add your keywords to your alt tags and filenames. This gives search engines a better chance of recognizing them.

Avoid Keyword Stuffing

Keyword stuffing refers to incidences when an individual tries to manipulate their page’s position by overloading keywords into their meta-description or content abnormally. It is a good idea to limit your LSI keywords to no more than two along with your focus keyword to keep it fair and reasonable. You should also be careful not to use one keyword more than others, rather scatter them throughout your content uniformly.

Keep Your Context in Mind

When choosing your keywords and incorporating them, you also need to keep in mind what you’re writing about. You might be tempted to throw in all the relevant keywords, but again, to avoid keyword stuffing, you need to choose only the useful ones. For example, if you’re writing about Arnold Schwarzenegger’s political career, keywords such as “policies”, “governor” and “California” might be relevant, but “Terminator” is not. To conclude, creating SEO driven content can be difficult, especially since it is free and accessible to everyone. However, the competition also ensures that every page tries to produce quality content to improve their rankings. When used well, LSI keywords not only help your rankings and drive traffic but also adds variety to your content and makes it more interesting to readers. With enough relevant and quality content, you can see results extremely quickly.
