Use div tags too hide words as content for seo optimization?

[MerryG]

General rule of thumb for SEO - don't 'hide' anything. The major search engines are looking for applicable, appropriate content for the website's end user. If you hide key phrases it might work for a while but if the SE gets wind of it (especially Google) it will likely ban your site. Best thing to do is write good, user-friendly, informative text, litter it with 'hot' keywords to other areas of the site and develop a symbiotic link exchange. The more links coming to your site from other sites, the better, whether they're reciprocal or not.
