Live from the Googleplex, Hal Varian explains, the Google Ads Auction.
This is a must-see, even if Hal isn’t deserving of an Oscar…
Do you think the pie chart of Quality score is accurate?
- 60% CTR (“user feedback”)
- 30% Adwords Account Architecture (“relevancy”)
- 10% Landing Page Factors (that’s all? -WTF)
If that is true…
Landing page relevancy influence over overall Quality Score accounts for only 5% of Quality Score?!
March 21 2009 Update:
Richard Ball commented: "Keep in mind there are different Quality Scores for search: ad rank vs min bid. The landing page is only used periodically for the latter. The pie chart must have been a "blended" QS. IOW, landing page is a big factor when setting the min bid (now first page bid) but not a factor when calculating the ad rank.
See the Quality Score Formulas section. They should have done a different pie chart for the 2 different Quality Scores, IMHO."
Look for the newer post about this issue, with our experiment and screenshots.
