How to do SEO?

In order to make your site good ranking with high traffic, On-Page and Off-Page SEO Optimizations are essential. Without on page, we cannot achieve anything in off page optimization. Without off page, we cannot gain backlinks or Page rank. The search engines must be able to find and read the content on your website to understand that it is relevant to what the search engine user is searching for, therefore you need to 'optimise the website' or address the onsiteSEO issues to ensure that it is achieved. Put simply there are 2 main strands to onsite SEO: Content or Keywords, Technical Site Issues. Then start from Directory submission, Social Bookmarking, Article Submission, Forum Posting, Blog posting and commenting.

Their is so much you can do for seo... and it takes plenty of time base on all the responce to OP post

First of all, the content in the Membership section is awesome. The training modules, videos and the stickies in the forums provide great tips for any in-house marketer. The many tools are very useful as well, of which HubFinder is my personal favorite.
However, what's even a bigger benefit (in my opinion), is the community. People share their failure- and success stories, you offer solid advice, and other community members do the same. For example, it seems like you just can't ask a question in the link building section without getting a useful reply from Deb Mastaler This is great for folks working at an SEM agency, but even more for in-house people.

Do On-Page Optimization (its done within your site) first then next is Off-Page Optimization (done outside your site).

i think you need to do have knowledge for SEO so have a habit to read books on SEO and online tutorials
