Help > Adwords - Average Position By Google
This is the estimated rank of your ad on the page.
1.0 is the highest possible position. (Because these positions are averages, you may see fractional numbers like 1.2 or 7.4.)
Keep in mind that Google domains display up to 10 ads on the search results pages.
If your estimated position is higher than 8, your ad may appear on our second page of search results, where it is likely to receive fewer clicks.
