.: What The Hell is... Latent Semantic Indexing
By:Ben Kemp
Category:Home / Internet Marketing / Search Engine Optimization
Latent semantic indexing (LSI) is a concept whereby your site is also assessed on content other than the keywords that you are obviously targeting in the on-page and off-page elements of the site. Partly, this is to combat using keywords to draw traffic to content unrelated to the keywords - as porn, gambling and pharmacy spam sites are inclined to do.
More importantly, its because there is a very high mathematical probability that a site that is genuinely about a specific topic ALSO includes multiple iterations of related words, phrases and terms e.g.;
- nouns, verbs and adjective variations
- word derivations
- synonyms
- hypernyms
- hyponyms
Therefore, the major search engine algorithms' are now applying the concepts of "latent semantic indexing" and taking into account all word relationships within the site. Whilst an algorithm might lack "intelligence," the mathematical model is quite robust and delivers extremely accurate relevancy assessments.
To apply the concept of LSI to your site, its a matter of NOT over-loading your page with primary keywords (spamming) but instead, using variations to more accurately describe your topic or theme; E.g. using the term "SEARCH" the following options appear;
Variations or derived words; searcher, searched, searching,
Synonyms - query, queried, querying, seeking, looking, finding
Hypernym: activity, examination, examine, higher cognitive process, investigate, investigating, investigation, look into, operation, scrutiny, see.
- Synonym: explore, hunt, hunting, look, look for, lookup, research, seek.
- Hyponym: angle, beat about, browse, cast about, cast around, comb, cruise, divine, drag, dredge, exploration, feel, finger, fish, forage, foraging, frisk, frisking, fumble, gather, go, go after, grope, grub, hunt, leave no stone unturned, looking, looking for, manhunt, nose, poke, prospect, pry, pursuance, pursue, pursuit, quest, quest after, quest for, raid, ransack, ransacking, re-explore, rifle, rummage, scan, scour, scouring, seek out, seeking, shakedown, shop, strip-search, surf, want.
- Derived: searcher
Noun
- Hypernym: activity, examination, higher cognitive process, investigating, investigation, operation, scrutiny.
- Synonym: hunt, hunting, lookup.
- Hyponym: exploration, forage, foraging, frisk, frisking, hunt, looking, looking for, manhunt, pursuance, pursuit, quest, ransacking, rummage, scouring, seeking, shakedown.
Verb
- Derived: searcher.
- Synonym: explore, look, look for, research, seek.
- Hypernym: examine, investigate, look into, see.
- Hyponym: angle, beat about, browse, cast about, cast around, comb, cruise, divine, drag, dredge, feel, finger, fish, frisk, fumble, gather, go, go after, grope, grub, hunt, leave no stone unturned, nose, poke, prospect, pry, pursue, quest after, quest for, raid, ransack, re-explore, rifle, rummage, scan, scour, seek out, shop, strip-search, surf, want.
The purpose of the example is to show that there are many ways to describe the same activity, product or service.
How to Apply Latent Semantic Indexing
Implement LSI on your site by thoughtfully including variations, derivations, synonyms, hyponyms and hypernyms of your primary keywords and phrases. You will more effectively convince the Search Engines of your content theme than you would by stuffing multiple iterations of the same primary keywords into those page/s!

1). SEO Contests: Good or Bad?
As a webmaster you probably already know what a SEO Contest is or you surely came across some of them or even participated in. Some of the major SEO contests organized are the v7ndotcom elursrebmem (by v7n.com), Ambachdotcom, Carcasherdotcom, and more recently the Cpayscom2 Online Casino where the winner gets $10,000 for ranking number one on MSN. Now the big question is whether it is good or bad to organize SEO Contests.
2). High Paying Lateral Keywords
If you run AdSense on your site you know that some words pay more than others, much more in fact. More than likely you have also learned that terms like "structured settlements" and "mesothelioma" can produce incredibly high PPC revenue, if they show up on your site at all. Unfortunately hundreds of thousands of other webmasters are "on" to this practice judging by the number of sites created regularly to capitalize on the phenomenom.

6). How to Make a Sitemap For Your Website In Five Steps.
A website's sitemap can be compared to the table of contents of a book. The sitemap is important because it guides visitors to the parts of the website in which they are interested. The sitemap allows surfers to reach their destination without wasting time.
Sitemaps are also important from the point of view of search engines. If the search engine finds a sitemap it is much more likely that your page will be fully visited (spidered) and indexed; allowing web surfers to find your pages in their searches.
