I hope this thread will be active since I'm very interested in white hat SEO techniques.

Here is a list of my favorite techniques:

First of all you must focus on quality content. In my opinion this is the most important factor ! For me the content is always a priority. I also recommend making proper use of heading elements since search engines give more weight to the content within the heading elements. Also provide pages with proper titles and meta data.Keywords and key phrases are important as well. You should assign each page 2 or 3 keywords throughout the important elements of the page (title,meta description,meta keywords,heading elements,text,alt tag,title tag,links). And pay attention to the inbound links.

Feel free to add other techniques.

I though that the best way is buying traffic , isn't it? Because it is the best and the easiest way !

thanks for the techniques.

This techniques is good yes, but i didn't heard about white hat so much that why i prefer better using black hat methods which really working but not white hat! White hat technique is legal?
