Each time your ad appears for a given keyword, it'll most likely be in a different position, depending on your Max CPC and CTR as compared to your competitor's Max CPC and CTR.
If you were to take each actual position and add up those numbers, then divide by the number of times you've appeared, that would be your Avg. Pos.

If not, it should be :)
Hey, but now you know your postion is much better than you thought it was! ;)
...If I show up on the 3rd page of results but I'm the ad on the top of that third page, does it count as position 17 or position 1. I'm assuming there are 8 ads on each search result page.
Assuming 8 ads per page, then it counts as postion 17.
