After finding the LSI keywords. Your next step is to use them wisely. As a result, your website will be optimized for content and increase traffic. So how should they be used?

1. Use LSI Keywords in Title Tags

Typically, LSI keywords are “long tail” versions of the main keyword. For example, if your main keyword is “SEO tips”, then surely one of them will be “SEO tips and tricks”.

In this case, you should use them in the title. This helps you to add both “SEO tips” and “SEO tips and tricks” to the title.

2. Add LSI keywords in Meta Descriptions

Use LSI keywords in Meta Descriptions to attract people who are searching. However, you should not try to stuff too many keywords, which will affect the readability of the Meta tag. And Google doesn’t appreciate doing this either.

3. Use Long-Tail Search Terms in Image Alt Text.

Put alt tags for all of the photos in your post. You should add some LSI keywords to the alt tag. Similar to the above, you should only add them in moderation, not too much stuffing.

Your LSI keywords should also be reflected in the visuals you use throughout the text.

4. Use Main Keywords and Semantic Keywords in Content

  • LSI keywords are not intended to be used in place of the primary keywords; rather, they provide supplementary information.
  • Keywords should be used extensively. If you forget to include the main keywords, your website’s ranking will suffer.
  • The primary keyword serves as a connector for related semantic terms.
  • Overstuffing can occur if more than two LSI keywords are added to a single primary Keyword.
  • Using this method, you can escape Google’s penalty for keyword stuffing. Facilitate a speedy comeback of your website if Google has punished it.
  • This technique boosts search engine rankings without resorting to keyword stuffing.

5. Put LSI Keyword in Header

You should add some LSI keywords in the subheadings of the article (H1, H2, H3 tags). Google pays special attention to the titles of articles. In addition, they also make it possible for you to divide your content into smaller categories.

However, you should also filter the list of LSI keywords because some keywords are not related to the current article content. You can take advantage of them in the next articles.

6. Anchor texts should consist of LSI keywords.

Optimizing the Anchor Text for a Keyword can affect your SEO.

For example, articles on other websites always use the keyword “web design company” to link back to your website. This affects the ranking of other related keywords.

To maximize the benefits of search engine optimization. You should use LSI keywords, such as “web development company” or “web design service” in your anchor texts.

7. Focus on context and readability

Some Bloggers make a pretty serious mistake, adding random LSI keywords. LSI keywords help content become more quality and rank better. However, adding them indiscriminately like that will not bring any benefit.

Using relevant keywords too many times will reduce the readability of the article. Please check back carefully after you have optimized the article using LSI keywords.

If any sentence is too forced, or unnatural, delete it. If necessary, replace it with a new sentence or paragraph.

Operational objectives of LATENT SEMANTIC INDEXING (LSI)

Search engines use LSI to evaluate the quality of the content on a page. To do this, the tools check which words should appear with a certain search term or keyword.

LSI is designed to help searchers find more things related to the keywords they are looking for. For example, if you want to order vegetarian hot pot for dinner, you will probably search for the phrase: “Nearest place that sells delicious vegetarian hot pot”

In this case, “vegetarian hot pot” is the main topic and Google will appreciate websites that have words like “vegetarian hot pot with mushrooms”, “frugal hot pot”, “mixed vegetarian hot pot”…

Because these keywords are often used in pages that rank high as well as receive a lot of user searches.

Google has confirmed that using more LSI keywords will often help your page rank better. Users tend to search for any topic in different ways.

But if your page has more LSI keywords. It will give Google a lot of context and information as well as match the search terms entered by the user.
