CPMs back to previous levels

After a dip in Q4 of 2017, CPMs in Q1 2018 stabilized at $116.9, just a dollar below the averages we observed in Q3 2018, and up 13% from last year.

For the past two quarters, median CPCs for Google Search ads were continuously declining. The prices plummeted at the end of last year, averaging at $0.90 per click. This downward trend seems to be over; Search ads CPCs surged to $2.76 per click in Q1 2018.




CTRs show a steep decline from last year

 After a dip in Q2 2017, Search ads CTRs rose up to the previous level, before dropping way below the 2017 average. Q1 2018 CTRs are 47% lower than they were at the same time last year.




Google Search ad trends in Q1 2018

 As you can see, the prices for Google Search ads rose significantly in the beginning of 2018, while the click-through rates dropped by almost half compared to end-of-2017 results on the AdStage platform. It’s important to note that the AdStage benchmarks represent aggregated data from the accounts linked to our reporting platform, so the numbers don’t necessarily illustrate the larger Google AdWords trends.

Many factors can affect an individual CPM, CPC, and CTR. Internal factors like historical campaign performance and unique optimization strategies are obvious reasons these prices differ. In addition, the dynamic and fragile nature of the ad ecosystem, and a change in balance of supply and demand can drive the ad costs up and down very quickly.
