Question though... by time MSN comes out with their ads, wont that drive down the people bid on Google and Y! ads therefore driving down what we can make per click? It is just simple mathmatics. if there are less people competing for ad spots (since the total number of companies advertising will be spread across 3 major adchains instead of just G) in adWords then the bids will be lower. lower bids = lower click $ for us? am i right or am i way off base here?
simple answer no One will ever able to compete google ..microsoft adcentre is still a little baby and yahoo ppc system will never come out of beta...
