I have a new site in progress here that I have been incorporating a few new things into that I haven't done on previous client sites.
Specifically I am putting together a glossary page and named it aptly so in addition to applying the html tags of DL, DT, DD that I wasn't aware of. Besides that each term is given a bookmark on the glossary page. Then throughout the site, where ever it is in context, I link to words that are considered keywords but may need to be defined for the visitor (medical terms). So a link would look like this...
<a href="example.html#Dweeb" title"see definition of Dweeb on glossary page">Dweeb</a>
And the linked definition like this (term borrowed from W3C) :p ...
<dd>young excitable person who may mature into a nerd or geek</dd>
What I have noticed is that keywords throughout a site that link to meaningful related pages within a site are loved by Google.
As far as traffic is concerned, for a regionally focused site it isn't always a bad thing to not receive the visitor if they are from the international community at large and just looking for a definition of a term -- it will save the bandwidth. But there is going to be SEO benefits received locally or regionally. I've noticed this on another client's site even though it isn't as fine tuned as what I am applying now. Live and learn!
