I've been trying to figure out why my Quality Score for most of my keywords is just OK, and why I'm having such a hard time getting my ads to show even with super high bids. But this has to be the reason...
I just went and created a sitemap and submitted it to Google. Hopefully they will crawl all my content pages pretty quick, and this will help my Quality Scores.
Have I ruined this adwords account? Should I create a new one and start over once all my content pages have been spidered? Or do I just wait it out?
They aren't just going to show 'any ad' right away, especially when that new ad takes up the spot of another ad with good performance history. They know that ad will get clicks...they're not so sure about the new one.
What if the new ad doesn't work? What if nobody clicks on it? This is why Google slowly rolls out new keywords and ads. If they show it for a whole day, and nobody ends up clicking on it, they lost everything they could have made with the older, more established ad.
Therefore, the system will test it out little by little, until it gets enough clicks for google to say "ok, this ad is working pretty good...people seem to like it, so i'll loosen up on showing it."
