Hi, Can you be specific on your thread because its confusing. Ranking 2 position is better than 4th position so why do you want to downgrade its rank.
He meant PR. You need to have a lot of external links. And the best way to do that is to build a lot of quality content
Except that PR is obsolete and isn't being updated publicly. So, unless he has some secret way to get data from Google he'll never know if he's successful.
You need to work little hard for increasing page rank from 2 to 4. It is never easy. But any way Page Rank will be obsolete in future in-case you still want to work on it, you need to generate backlinks from higher page rank site then yours to increase to PR.
Doesn't matter how hard he works, his page rank is never going to increase. Wrong! Page rank is obsolete NOW and it is never going to increase, Educate yourself before trying to increase your post count.
Your page rank toolbar will no longer have accurate PR data as PR is officially not being updated for public view.
