The average placement of page on search engine results pages (SERP).
Anyone familiar with mathematics or statistical analysis knows that average ranking can be a misleading indicator. For example; suppose an ad is triggered to be displayed 6 times (6 impressions) in the following positions: the average position of 8, 8, 8, 8, 8, 2 is 7, although it never appeared in the 7 position, but only appeared In two positions.
As mentioned earlier, the average is an average, so the number of impressions your ad receives in each position will be weighed against the final average accordingly. Even for very effective ads, the average position rarely reaches 1 (especially if they get hundreds or thousands of impressions), and we see the average position more often.
The ranking of 1.1 or 1.2 is only 1. You can also extract reports from dimensions to show the average position of each hour of the day and day of the week to understand when the ad appears in the high or low position.
