Latent Semantic Indexing

Latent Semantic Indexing (LSI)

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

The purpose of the example is to show that there are many ways to describe the same activity, product or service. Thoughtfully including variations, derivations, synonyms, hyponyms and hypernyms. 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 the page/s!

A ‘Baker’s Dozen’ SEO Tips for WordPress

- How to Cook Up a Traffic Storm on Your WordPress site!

As a general rule, from an SEO perspective, bear in mind the most fundamental issue. Google loathes duplicate content! Google is trying to index and categorize the billions of pages on the web and calculate each page’s relevance to specific search queries. Therefore, to have any chance of attaining appearance in Top 30 SERP’s, pages must be accurately described…

Keep in mind that Google is an entirely automated text indexing system doing its absolute best to deliver the most relevant content to its core users. Those core users are NOT website owners!!! Google’s main focus is on its search customers. If you want your website to get noticed, you’ve got to assist Google et al in every way possible, by accurately describing your own content.

Make it clear and unequivocal what each page is about. Ensure it is original content, properly described, and easily accessible…

Apparently, there are over 200 elements that Google assesses as its trying to calculate a page’s relevance to a specific search query. Individually, some of them are almost insignificant. Collectively they add up to prominence or obscurity! The thinking man understands that the more elements you get right, the higher the probability of appearance in Top 30 SERPs. Here’s a dozen of the primary indicators of unique content to an SE spider;

1.) URLs:

Precise control of every page URL, carefully using primary keywords / phrase. Use Permalinks wisely!

2.)  Title:

70 characters limit. Accurate, carefully using primary keywords / phrase. The single most important element for every page!

3.) Meta Description:

150 chars limit. Accurate, carefully using primary keywords / phrase. By default, its used verbatim in Google SERP’s. Its very important to write a catchy phrase incorporating primary keyword phrase, one that impels viewers to click on it!

I always use All In One SEO because I’m a “content control freak” and want to make sure every word is in the right place. Dynamic meta-tags are better than no meta-tags – but the ability to manually input as many elements as is possible is what makes the overall difference to SE Rankings… Read more
