This is the part that got me:
We've also added some language to anticipate Google's retrieval of advertiser landing pages. To further improve program quality, our system will soon visit and evaluate all landing pages specified in AdWords ads.
Umm... I kind of thought that was already happening. I thought landing page was already part of the quality score?
Note: Your site's inclusion or ranking in the Google search index won't be affected (positively or negatively) by AdWords system visits.
Confusing because all along I thought I was paying so much because Google didn't give me much "ad quality score". So I made sure to follow every SEO principle and still no change.
Now what will happen?
Far too many surprises and contradictions in Adwords of late!
