Auction insights Averaging

Visitor ✭ ✭ ✭

Hi all,

 

I have a quick question regarding the calculation of Impression Share figures across multiple keywords in the auction insights report. Is this figure based on a weighted average of Impression Share at the keyword level or a straight average or some other method? I've done some calculations for one of my accounts and cannot come to the same IS figure Auction Insights displays for the keywords and date range I've selected.

 

Any help would be appreciated.

Hello;
Google does NOT disclose the formula...so, you cannot check the numbers. Google's formula involves a "forecast" / prediction of "if -then", based on an algorithm it developed.

For IS due to rank and impression share I would use the numbers with some caution, because you do not know what is  (in Google's language- see below) "impressions you were eligible to receive." and what are "ads weren't shown on the Search Network due to poor Ad Rank."

Hello all,

 

I've come across an interesting thing in the Auction Insights report recently: when I open the report, I find a nice "disclaimer" saying: "10% of available impressions (from 53070 keywords) were used to generate this report. Learn more"

 

Of course, I tried the "Learn more" thing, but I cannot find the reason why only 10% of available impressions are taken into the report. Tried another campaign with a little bit more luck - 66%. Has anybody got any ideas considering this? Should be interesting!
