What Is Latent Semantic Indexing?
Latent Semantic Indexing or LSI describes a search engine system that aims to take search engine and directory searches implemented by machines and ‘humanize’ them by returning less results that match only keywords, and actually return sites that have the same theme for which the surf
A websites matching and inward linking have a new and significant companion, that being superb content and data which is accomplished by Latent Semantic Indexing. The idea is that because of Latent Semantic Indexing our content pages can now be creating naturally securing a more desirable flow and feel and yet acquire a high search engine rank. We no longer have to make in an unusual repetitive way just to make certain that page was rich in the keywords or keyword phrases.
Of course, you would still want to apply your keywords in your writing, but you would no longer need to include that keyword in all possible instance to be properly ranked. This method is called keyword optimization, and it typically made writing seem poorly written grammatically and was very repetitive. Using Latent Semantic Indexing, a site would likely be able to vary the occasions of the keyword and use other terms to spice up the original content.
Latent Semantic Indexing would also be able to investigate certain keyword phrases and verify a few things from those phrases. For instance, if you were to type in the words “fish tank repair” your results without Latent Semantic Indexing would return a list of all website with high keyword prevalence for the word ‘fish’ the word ‘tank’ and the phrase ‘fish tank’ and the phrase ‘tank fish’. These would include fish sites and tank sites all where you would ‘search’ for ‘fish’ or ‘tanks’ not necessarily ‘fish tanks’.

With Latent Semantic Indexing, the systems would know that you were looking for a fish tank, and would then pass over fish sites or any other site that was not related to fish tanks. The concept is that fewer known and lower ranked keyword sites that more effectively match the subject for which you are pursuing would acquire an increased listing\/ranking on the search engine or directory site and would increase page views for these appropriate sites and make searching simpler for the intermediate web user.
Google was most certainly the innovator for using Latent Search Indexing, other popular search engines and directories after a while also began using this technology. In addition to Latent Semantic Indexing there are other techniques that could have a much the same effect which include Query expansion document and query classification, topic models like latent dirichlet allocation.
Your best bet is to try to build your website and content rich as possible, and still focus on links and keywords, but don’t forget because of Latent Semantic Indexing that your subject matter and website will quite likely not require all this back work to get listed properly as once was the case.
So what may we do to create our pages improved and SEO compatible for semantic search? We really should write pages that are very subject matter oriented with elaborate and semantically rich content. Once you get under way writing on a topic, you will immediately include semantically related words. For e.g., if I am producing a post on “music”, words such as “trumpets”, “drums”, “jazz” etc. will start turning up on the page. If not, make an extra endeavour. If an individual skimming through the page can not say what the page concerns in a couple seconds, there is something wrong.
