When it comes to building traffic and increasing pagerank there is no one you can ask rather than the Big G itself (Google). So Its very important to know how and now what Google has done is that it has put it up all in One presentation for fellow users to understand it.

You can watch a Half an hour presentation which tells users how their website gets noticed and how it is then slowly gets better and better. Check it out here. For slow connections it will take some time to load so have some patience.

Also one thing that i read written by Google and i wanted to say that “Writing One post a week is better than Writing Rubbish Daily” and do agree with them.
