which is a totally legitimate page and has <title>Blue Widgets</title> and <h1>Blue Widets</h1>. I have "buy" and "blue widgets" in the ad text but it still says the QS is OK. It's been about a week now. Is there something else I need to do to raise the QS?
"Blue widgets are blue and every one can use a blue widget since blue widgets are great! Buy a blue widget today and you'll be very happy."
The above text seems to work well for a lot of people across 100's of subjects. Don't forget to slap 25 ads along the borders - Google seems to like that too.
Here is an example I find:
blue widget have OK QS
but
blue widgets have Poor QS
I agree that Keywords, Ads and Landing Pages should have some quality score, but their algorithm is not good enough. I think they should in alpha phase, and not to be released.
