The world of SEO is constantly evolving. One recent trend is the use of LSI or Latent Semantic Indexing keywords in response to search engines employing LSA or Latent Semantic Analysis. Let’s unpack these two terms. Latent Semantic Analysis is a system for processing natural language in online content. The actual system is more complicated than I intend to discuss in this blog post. If you are interested in a more detailed description check out this Wikipedia article on the subject. In very general terms, LSA involves the analysis of the relationships between groups of pages of online content by comparing the various terms that each page uses relative to a specific topic. That is (again, in very basic terms), LSA involves the search of multiple documents scanning for words or phrases which are similar or related in their respective meaning. This is a much different analysis than the traditional keyword search type of analysis employed by search engines.
WHAT DOES THIS MEAN IN TERMS OF SEO CONTENT WRITING?
Essentially this means that in order to write more robustly optimized content, the content should include Latent Semantic Indexing keywords. LSI keywords are words related to the subject of the content. These would include not only synonyms but also phrases and paraphrases as well as other words which are close in meaning to the keyword that would best exemplify the main point of the content. For example, if the keyword for this blog post were SEO Salt Lake City then instead of sprinkling SEO Salt Lake City three or four times throughout the blog post I might use the following terms generated with the help of an LSI Keyword Generator:
Obviously not all of the words or phrases generated in this list are appropriate but the list does provide a general idea as to how a related term or phrase can be used as an LSI keyword. The main point is that the standard keyword, although still important for the purposes of search engine optimization are not as important as they once were. Moreover, to achieve the most robust optimization in terms of content writing it is important to now think about including terms (i.e., words or phrases) that are related to the keyword in some logical way. It would be difficult for a content writer to know exactly what are the best related words to use which is why an LSI Keyword generator might come in handy.
