When you find the right LSI keywords, the published written content has the potential to rank high in search engines.

Talking about SEO (Search Engine Optimization) cannot be separated from keywords. But, have you ever heard of LSI Keywords? If not, then this article is very worthy to be read as learning material for us together.

What are LSI Keywords?

What are LSI Keywords?

LSI (Latent Semantic Indexing) Keywords are search queries that are related to the main keywords you are targeting. In more detail, LSI keywords are words or sentences that are considered semantically relevant by search engines

For example, when you type the keyword keyboard into a search engine, it is likely that the search results that come up will be about computer keyboards and musical instrument keyboards. This is because the keyboards have similar meanings, so Google gives quite ambiguous results. To avoid this condition, other LSI keywords are needed, such as 'computer', 'device', and others.

Therefore, LSI keywords have an important role for SEO, so it is recommended that writers write articles with keywords that are specific and appropriate to the content of the article when these keywords are searched for.

These keywords become a bridge for users and search engines to understand the content more deeply. According to Backlink.io, this technology was introduced in 1989 as a methodology for retrieving text-based data objects, so that determining a topic is better because it uses related words and sentences.

What are the benefits of using LSI keywords?

Actually, the benefits of LSI keywords for SEO are something that is still a mystery, some even say that this is just a myth. However, in fact, LSI keywords were implemented by Google in one of its algorithm updates in 2004, where the search engine already understood synonyms and semantic phrases.

There are several benefits of LSI keywords that you need to know, as quoted from Neil Patel's page, including:

  • Improves content quality because it uses many terms related to keywords
  • Written content is still considered relevant without using excessive keywords
  • Make content easier to find by internet users
  • Avoid penalties from Google for using keywords too often
  • Search engines can provide higher ranking opportunities, because there are many terms that can increase the site's ranking

There are a very large number of queries searched by users on search engines (Google), hundreds to thousands of which have never been searched by users.

Therefore, LSI Keywords are here to help Google display quality search results even though the query has never been searched for before. The following are a number of benefits from LSI Keywords:

How does LSI work?

As previously mentioned, the way LSI keywords work is quite complicated. This is because LSI keywords use quite complex mathematical formulas to understand the relationship between words. However, the way LSI keywords work can be simplified and understood with a process like this, namely:

So, search engines will look for similarities in the words used. Then, the word will be identified using semantically connected words. After that, the search engine will group these words into different categories.

To group these words, LSI keywords are needed. That way, search engines can determine words that contain these two meanings. As previously mentioned, LSI keywords can group the term 'keyboard' into two parts, namely those in the computer context and those in the musical instrument context.
