26 Jan Best Practices After “Average Position” – Google Ads Search Impression Share Metrics Explained
Google Ads removed average position in September 2019. And whenever there’s a removal of a metric, advertisers want to understand the why behind removal- especially if it was a useful metric.
Google explains the removal by citing that average position resulted in runaway rising CPCs, and the removal attempts to curtail quickly rising CPCs. This is likely true because it’s become much harder for gung-ho advertisers to vie for the number one average position. If they want the number one position, they also have to aim for absolute top Google Ads search impression share and rate.
We’ve developed some clear best practices when it comes to optimizing your campaigns after Google eliminated average position six months ago. But first, it’s important to recap some of the most important competitive metrics in Google Ads:
Google Ads Search impression Share Metrics – useful for bidding and CTR optimization:
– Search top impression rate = Impressions on top/Impressions
The % of your impressions that showed above organic results (~1-4 position) out of all of your impressions.
– Search absolute top impression rate = Impressions on the absolute top/Impressions
The % of your impressions that showed in the number one position out of all of your impressions.
Metrics for all eligible impressions – useful for budget and reach (Google Ads Search impression share) optimization:
– Absolute top impression share = Impressions on absolute top/eligible impressions on top
The % of your impressions that showed above organic results (~1-4 position) out of all eligible impressions
– Google Ads Search top impression share = Impressions on top/eligible impressions on top
The % of your impressions that showed in the number one position out of all eligible impressions
Overall, top impression metrics are more precise than average position. Also, the new top impression rate and share metrics show what has the most effect on an ad’s position, bids, or budget. Average position told us the position of the ad, but this varied wildly depending on budgets and bids. Overall, the new “top impression” metrics are a more reliable gauge of your ad’s reach and cost-efficiency.
Best Practices for Google Ads “Top Impression” Metrics
In the past, advertisers targeted an average position of 2.5 to maximize the ad’s reach and visibility while minimizing costs. Now that average position is gone, it’s essential to focus on the % top metrics to optimize the ad’s reach and efficiency.
Generally speaking, we recommend applying the 80/20 rule whenever possible, and this situation is no exception. Focus on optimizing the following three metrics to around ~80%:
1. Search Exact Match IS = especially for exact match keywords. You can push this above 80% without worrying about diminishing returns.
2. Search Top Impression Share = this should be around 80% for most keywords, above that maybe pushing towards diminishing returns
3. Impr. (Top) % = this should be around 80% for most keywords, above that maybe pushing towards diminishing returns
