Best LSI PBN Article Keyword Research Using the Last Keyword Tool

Keyword Research is one of the cornerstones of good search engine optimization, and perhaps the least understood.

When you gather the most profitable keywords, your online business will take off. Bet on the wrong keywords and you will spend a lot of time and money with nothing to show for it.

Most amateurs will fail to research their market properly and then believe that online marketing simply does not work. They woefully return to their expensive and often futile television ads.

LSI is an acronym for Latent Semantic Indexing and can be a bit of a hot button when SEOs get together and discuss strategy. Wikipedia has a great entry on what LSI is and how it works. We have also written an article on Latent Semantic Analysis because there is so much confusion and misinformation about it. 

As for how we use it, we fetch the top 100 pages in each search engine for the seed keyword, filter the pages for junk (tags, javascript, etc), then create a Latent Semantic Index and use that to determine a relevance score of each returned keyword to the seed as a matter of relevance. 

Because each corpus (set of returned pages) is different, the LSI score is a relative value rather than an absolute. A '10' in one project might be the same as a '16' in another one, which is part of the reason we have custom tunable filters and columns.
