Google is now a pay to play engine from being an organic search engine. It seems to have done so unknowingly. When it comes to a high PR, the number of backlinks you have is taken into consideration. If you have money, you can pay for text link advertising which will lead to great ratings. Spamming blogs is yet another way to boost the ranking of a site. With just a few paid for text ads, you can have your rankings boosted. There are some webmasters who rank high on MSN and Yahoo but they don’t rank well on Google.
