Inside the New Google Display Network Performance Metrics

Some clever eyes spotted this as early as late last week, and yesterday Google officially announced it:  You can now see your “Relative CTR” compared to other content ads (text or display ads) shown in the same ad spots on the same content network pages.

Google also now says that your ‘relative CTR’ is a ‘good indicator of your content network quality score (not that that’s a big surprise though, we’ve always pretty much known content QS was driven by CTR relative to other advertisers’ ads in that same ad spot).

How to View Your Relative CTR

You can view your “relative CTR” rating at the campaign or adgroup level. To see it, go to “Customize Columns” and check the box to display it. This works in the All Campaigns screen as well as when you drill into a specific content-only campaign:

To evaluate these numbers, HIGHER IS BETTER.  Anything below 1x is “below avg” and will likely have fewer impressions that “above average” 1x adgroups.

So if my relative CTR is 2.3x, I have a 2.3 times better CTR for that adgroup than my competitors.

If my relative CTR is .8x, I have a 20% worse CTR than the average CTR for that adgroup.

How To Use This Data

Now you can clearly see with it which adgroups desperately need new ads: ads that can get a relative CTR above 1x to bump out your competitors. Work on new ads for these right away, and evaluate your relative CTR for that adgroup daily until you get up over 1x. Then keep going to improve even more if you want to really lock your competitors out.

If you use the date selector to look at a longer period of time (say the last 30 days) you can get an idea of how the competitive landscape moves and shifts in your campaign. You’ll also be able to tell when a competitor comes up with a killer new ad that’s forcing down your relative CTR, reminding you to go check the ad out on your top content placement pages and see what’ they’re doing and beat it:

Impression Share % for the Display Network is Also Back

Google has shown you your campaign’s Impression Share % column for a while now, but for Search campaigns only.

A while ago a similar metric appeared for display network only campaigns, but then disappeared.

Google is now showing Impression Share % again for display campaigns. This shows you how much of the total display ad or content ad pie you’re getting for your campaign.

To enable it, on your All Campaigns screen, click “Customize Columns” and check the box for the “Impression Share” column. You’ll then see it likeso:

Overall, we’re seeing a lot more information on what’s happening behind the scenes in the display network auction: very cool. Prior to this you just had to make assumptions about what to tweak and rely on fuzzy metrics like avg position and actual CPCs.

Out of interest’s sake, in my top content campaign that gets around 50 million impressions a month, all of my relative CTRs are over 2x, which might be why that campaign has 73% impression share.

One More Thing…

Google has also announced that they’re adding an ad diagnostic indicator to help you see whether your ad is showing on a particular placement page or not:












This feature isn’t live yet for all advertisers, but should be by the end of July.

Relative CTR is the big one because on display, CTR = Traffic bottom line

I missed out on that announcement, so thank you! Half of my campaigns are at a .9 and .8 so I’m off to make more display ads. 

I’ve heard that adding a new ad copy to the adgroup within a display campaign may result in you losing your position since Google has to review the whole thing over again. True?

Thanks for the great article!

When kicking off with the GDN I also found the stats seriously lacking.

The relative CTR is certainly great once ads are running.

I do however feel the GDN is in serious need of more accurate bid estimates for new placements.

What’s your personal strategy for determining initial bid amounts?
