Well, for online SEO I recommend using much the same tools as for Offsite SEO.
Onsite SEO involves activities such as meta tags (title, description, keywords, etc), use of content categories (if using a WordPress or similar blog), SEO copywriting, internal structure of the site itself (read more about this in the web silo section), and pretty much anything else related to the actual content within a site. When I say content I mean content seen by humans or by search engine ‘bots.’ Both are important. Never create a site simply for the search engines nor just for humans. You must balance the content to appeal to each or you risk alienating the other.

Use this tool responsibly and your site will stay online. “Spam” the internet with garbage content and you deserve what happens to you.
