Not that any of you wanted to know, but wither may be derived from weder or weather, and means to dry up or lose freshness. There was a flap a while back when our dear friends at Comscore reported that paid clicks were declining at Google. Everyone went up in arms, and there was lots of analysis and Comscore felt compelled to publically defend itself. See – Comscore presentation on MediaPost. So I borrowed the title of this post from Giab Fulgoni’s presentation.
Click rates have been declining across the board, and if there is a novelty factor in the fact that video has a higher click rate than display, over time that’ll wear off and we’ll see a decline in video click rates as well. It’ll be interesting to see if, as postulated by the pundits, the overall higher engagement and interest in video and correlated ads will keep video click rates higher than display click rates in the long run.
At any rate, that’s not the reason for this post. It’s because there seems to be a sense amongst all the cognoscenti, insiders, publishers, ad network people, and even a few clients/advertisers that clicks may not be the perfect metric to judge everything. “Branding effects can’t be counted by a click.” “The fact that someone saw a display or video ad 10 times and didn’t click it doesn’t mean it didn’t engage him.” Go figure.
Most of us in the ad network and publisher business are sometimes frustrated by the singular focus by many an advertiser on CTR as the sole, defining metric. The point made by this article Why the Click Is the Wrong Metric for Online Ads and others is valid, which is that a CTR measurement isn’t the end-all and be-all for all campaigns.
But the problem with stating the obvious is not so much stating it, but what does one do about it. If we don’t understand the campaign’s goals enough to figure out what the correct set of metrics are for a campaign, we’ll all end up using the metrics that we’re used to, which are essentially CPM coupled with a CTR or CPA, which truth be told, ends up backing into an effective CPM anyway.
Rather than bash CTRs, we should stop generalising, and bemoaning the death of a particular metric and realize that this business is complicated and each advertising campaign may have a set of metrics, that taken together, in total will provide a measure of the campaign’s performance. I hesitate to say this, but some clients and advertisers should also be open to taking a look at engagement, view-through, mouse-over or other metrics as well, rather than the singular focus on CTR.
