Web Trade Forum

Thought I'd put out a list of what is covered in SEO.

SEO on page
- Everything related to meta tags, meta description, title etc
- Keywords
- Remove unnecessary/irrelevant stuff
- Unique content

SEO off page
- directory submissions
- article submissions
- blog posts
- forum posts
- paid advertising

I'm sure there is lot more that goes in to SEO, so what other things do you guys think will make up good SEO?

Edit - just realized I posted this in the wrong subforum. Mods please move this to the appropriate subforum. Thanks!
