How to get PR4 in 3 weeks after you bought the domain

3 weeks ago we bought a new domain, – google keyword tool showed that there are a huge number of searches (110k monthly searches) and there was medium competition.

After creating the site and getting some links to it (from several PR4 and several PR3 sites), I was nicely surprised to see that google gave to hp cheap page rank 4, with nice PR3 for secondary pages. Also the associated twitter account, get PR4.

Usually, until now it took 1,5months to get at best PR3 for a similar site. Maybe is Caffeine effect, as SEO guru Mateescu pointed out.

Now we must make sure it gets links also next months, otherwise it will drop fast to PR3.
