Last week Google accidentally let slip that they will be penalizing AdWords advertisers for slow loading times of landing pages. You can view the Google’s FAQ on this topic here.
(For those not intimately familiar with AdWords, if you are bidding $.05 for the keyword phrase “best keyword ever”, you may have to increase your bid anywhere from $.20 to as much as $10.00 if Google thinks your landing page is too slow.)
For those of you who don’t know: Google periodically cleans house in their AdWords program. They single out websites and assign them a poor “quality score”. These sites hit by this bad score have their minimum bid prices skyrocket to $5 or $10 per click. This effectively bans you from AdWords since most webmasters cannot afford to pay $10 for every click Google sends their way.
