1. HTML title
2. high-quality inbound links
3. meta description
4. keyword-rich text

We cannot specify any tip as best and other are worthless as it depends upon blog and SE behaviors. In my view point forum posting and directory submission is best one

I think that unique content is a start but not enough. What you have to do now is promote a lot each one of your contents, so it ranks better.
That means promote it in forums, blogs, press releases, etc.

Blog posting and forum posting is my favorite seo techniques.

White hat seo techniques for off page and unique and good content writing, meta tags, internal links, alt tags etc for webpages.

Engage on Social media. Think of a world without search engines and do your job

Do quality work, everything should be on quality base..

Uniqe content,High PR Bookmarking,Forums,Guest Posting.....

Some Best SEO techniques are:
fresh content
keyword
forum posting
blog commenting

There is no best seo technique in promoting your site. You need to learn how to analyze things and see what's working and what's not. That's the best thing that you can offer to your site rather than opting to the methods that are widely used by other people that pay little to no good results.

I think Social Media Marketing, Social Bookmarking, Link Building And Goods Content.

Quality content and high PR link building

SEO is mainly used for generating quality based backlinks so try Article Posting, Forum Posting, Blogging so also updating your websites with fresh content because content is king.

submit original content written uniquely and should distribute constructive information :)

high quality content and inbound links from high pr sites can make it perfect seo technique
