LSI (Latent Semantic Indexing)

LSI stands for Latent Semantic Indexing, and in general it simply refers to a mathematical method of finding and indexing documents or, in our case, contents, which, in a very easy to explain way, tries to understand the terms and concepts and what surrounds them in order to understand the contexts and therefore be able to relate more intelligently with the different documents, thus leading to a search for the most accurate or correct results.

In this sense, then, we can say that LSI Keywords are nothing more than making good use of the synonyms and related terms of a content we are creating, to give the possibility that this text is prepared to be interpreted in the most accurate way by search engines.

LSI AND SEO 💻

At SEO level, as we said, LSI is associated with those keywords or synonyms of our main terms. Although it seems a great novelty, semantic analysis in the field of computing has been used since the 1980s. But at the level of search engine ranking it has not been used for a long time. Previously the most significant thing was the density of keywords. But this is something that could be considered a bit old-fashioned, because using a word or term several times does not mean that it should be indexed better. That’s why Google, Bing and the company are working at LSI to analyze similar, synonymous and related terms in the text so that instead of quantity, quality prevails. This doesn’t mean we have to completely forget about keyword density, but just as excessive optimization used to be perfectly valid, now it can be quite harmful.

It is important to stress that this is not only a method by which search engines discard over-optimized content or something like that, but they can analyze an entire content and know the meaning or semantic sense of the word depending on the context.

To avoid getting into too technical questions about how the search engine algorithm works, we can summarize that search engines are always looking for the best content for a given search. Therefore, we can simply say that the use of LSI keywords helps us to improve our positioning with respect to the terms we want to work on. So, instead of overusing the same keyword in an article, we can use “the terms the search engine would expect to find” in the content so that it can classify or report it in the best possible way.

ADVANTAGES OF THE MATEMATIC METHOD 💯

This is a mathematical method used to determine the relationship between key phrases within a content. Search engines use it to better understand the topic of the text. Google rewards sites that include relevant LSI keywords with higher ranking and more traffic.

• Search engines can provide more useful and relevant search results, because they can decipher the language and rank topics based on synonyms and related terms
• Marketers can improve search rankings by changing their keywords to use LSI best practices
• Publishers can connect with a more engaged audience because their content is more targeted and able to connect with the right users
• Searchers can more easily find content that matches their needs and desires
