Hi Supply Chain,

yeah, all new swiss-army-knife of SEO is latent semantics - unfortunately it is nothing you could apply hitting a button ... ^^

Latent semantics is about structure of natural language and meaning of words. A (future) search engine (and possibly the old ones to a certain degree) will try to assess a written text by looking at the diversity of words used therein and the logical consistency of their combination inside this text. This is in order to reach a semi-intelligent understanding of what the text is about and of it's relevance and, comparing it to other relevant texts, it's importance.

I'll give you a simplified example: can a page be relevant for the query "bank" if it doesn't contain the word "money" too? A search engine working with latent semantics will even expect to see the word "money" on a page about "bank", plus a bunch of other words related to "bank" too.

Go to http://en.wikipedia.org/ and look for an article on a given search term ('keyword') you want to rank high for in Google and look which words and phrases will go well together with your keyword (see if you can find an article that has been voted "excellent"). This is where you've found an optimized text now that will do well in the sense of latent semantics ... (don't copy wikipedia, though :D)
