I was advertising Windows Vista pre-orders for OVER 2 WEEKS and the minimum activation bid was S$0.05. Soon after Windows Vista launched, more advertisers came on board, Adwords deactivated my account and asked for S$0.15 minimum bid. A couple of days later the minimum bid was once again raised, and this time to S$0.24! The question is why was I allowed to advertised at S$0.05 for over 2 weeks and then had the min. bid raised twice to $0.24 when I didn't changed anything, i.e. landing page or ad? Is this Google's way of pushing me out from the system for a keyword that's rising in popularity?
Yeah, funny isn't it. It says that I should try to improve the quality of my landing page or pay more.
