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:
