Latent Semantic Indexing and Strategies
Latent Semantic Indexing
Latent Semantic Indexing (LSI) is a way for search engines to view and rank web site pages for natural rankings. In behind the scenes the LSI algorithms analyze pages not only for keywords, but also for synonyms and other related words which might be expected to be present on the web page of the site.
How LSI was introduced into Online Marketing
Google Search engine bought a company called Applied Semantics whose software technology was used to extract and organize information from websites in a manner similar to the way that humans might act in the year 2003. The purpose was to help Google match advertisers of Adsense ads with the appropriate web pages where the ads would be shown. Initially Google Adsense matched keywords on the pages to keywords in the ads and a website owner earned money for every click he received from an ad shown on his site. However, the problem soon arose that millions of pages were being generated simply to contain relevant long-tailed keyword phrases to capture traffic from Google and the resulting profitable clicks on the ads. Content on these machine-generated pages was virtually non-existent and it was a frustrating experience for the person doing a search to only find spam. The problem for Google at this time was that they could not differentiate between these generated pages and the sites which actually contained valuable content.
More techniques, such as stuffing a page with keywords and using reciprocal linking strategies to increase search engine rankings, appeared on the scene which compounded the problem. However, reciprocal linking was soon discounted by Google and partially by Yahoo and MSN when one-way inbound links became more important in rankings than before.
Present SEO strategies in Latent Semantic Indexing (LSI)
- Develop themed sites on a broad scale rather than centering around one keyword.
- Instead of keyword padding struggle for more naturally worded and written pages.
- While you are adding the keywords try to include synonyms, related words, plurals, and a variety of tenses whenever probable right through your site.
- When establishing inbound links be sure that they do not all go to the same keyword; have inbound links go to a number of different keywords and applicable terms within your site.
- Do not bother seeking reciprocal links; inbound links are the key to LSI.
