10/10 Quality Score Mystery
October 21, 2008 1:05 pm Stuff...This truly confuses me.
- The keywords in red are “Inactive for Search”
- Keywords Four through Eleven have been deleted with no change to
the other keywords.
- Keyword One is a 3 part keyphrase. Lets say “Rubber Baby Buggy”
- “Rubber” is not mentioned on the landing page and “Baby Buggy” is only
mentioned once in the body, with no anchor or any other tags.
- “Rubber Baby Buggy” is not mentioned in either of the 4 ads. “Baby Buggy”
appears in only two of the ads headlines.

The only thing I can think is they are relying more on CTR than anything else. Makes sense with Hal Varian’s recent post about Quality Scores: “an ad that gets very few clicks shouldn’t really be shown”
No complaints, just an oddity I thought I would share.
