LSI stands for Latent Semantic Indexing, which refers to how the search engines rank a webpage’s importance based on how keywords are used on it. Every Internet marketer knows just how importance the right use of keywords is, but finding out which ones to use can be a tedious task for some. Hence the popularity of various keyword research tools and programs for SEO out in the market today.

Martin Avis’ program, Keyword LSI Spy 2, differentiates itself from the pack by offering more than just your basic keyword research service. It is capable of in-depth analysis of the keywords and meta tags of the highest-ranking sites for a particular keyword or keyphrase. Living up to the “spy” part of its name, Keyword LSI Spy 2 lets users see the words and phrases in websites – and their usage frequency – that brought these sites to the forefront of the search engines’ attention.

More than just primary keywords, though, the program also shows related terms and phrases, which are instrumental in the creation of dynamic, informative, and natural-reading content – something that’s factored in how search engines rank web pages. This feature would help make writing for search engine optimization purposes easier and perhaps just as importantly, more profitable.
