So why are we as marketers (especially agency marketers) so stuck on the term "engagement?" Industry trends suggest that digital brand advertising -- particularly on major publisher sites like YouTube -- tend to favor engagement and awareness-oriented campaigns over performance-based campaigns. If you ask 100 different marketers to define engagement, you'll get almost as many answers. Some will talk about click-through rate (CTR), impressions served and ad viewability. If they are familiar with video, they might talk about completion rate. If they dabble in social, they might throw around platform-specific metrics such as likes, shares and comments. Each of these has its own issues. The shortcomings of common engagement metrics The vast majority of clicks are not valuable. They're often a result of accidental clicks or (worse yet) fraudulent bot traffic. Although accidental clicks might convert occasionally, CTR is a relatively useless metric. When your agency partners project a CTR of 2% (or higher) and claim that the traffic is genuine, they're lying through their teeth. Impressions served and ad viewability are no more useful as metrics. Impressions are simply the number of times the ad was delivered and don't speak to the quality or value of whom the ad was delivered to. And although ad viewability tech projects the notion that those ads were seen by human eyes, the definition of viewability (e.g., 50% of pixels are visible for 1-2 seconds) is so loose that it's essentially meaningless. Worse yet, it's easy to fake. I've personally seen hundreds of sites that have a third-party verified 100% viewability score but are cookie-cutter sites that are put up en masse and flooded with robotic traffic to defraud advertisers. Completion rates, likes, shares and comments are nearly as inconsequential as clicks and viewable impressions. Although these metrics do give some indication of a user interacting with the campaign or brand, it's a major stretch to claim that they're driving revenue. Employ all the sentiment analysis and on-target audience tech you want. Those likes your video on Facebook received aren't worth what you're paying your most junior community manager. Marketers who are proudly touting impressive stats in these areas dread the day that someone important asks, "OK, but so what?" The path forward So if everyone knows deep down that these metrics are bogus -- and they are bogus -- why do agencies keep pitching them? Quite simply, they're easy to understand and communicate to brand clients who generally have a fairly primitive understanding of the real purpose of advertising. Also, they sound good. After all, if your brand spends thousands of dollars on a video ad, don't you want people to engage with it? Don't you want to know that they watched the whole thing? Don't you want to know that a highly touted algorithm reported that the impressions were served to the audience that your marketing team wanted to reach? Of course you do. But there's that pesky question again … "OK, but so what?" But there's a better way: performance-based measurement. Third-wave e-commerce brands and mobile game publishers are leading the way and have seen massive successes in operating lean, data-driven marketing departments that are uniquely focused on performance. The problem for most brands and agencies is that implementing and measuring against real metrics is hard -- and they get harder to measure the more established your brand is. But just because things are hard doesn't mean they aren't worth doing. So come on, marketers. It's time to stop being scared of the metrics that you know you should really be tracking. It's time to ditch engagement and focus on driving real value.
Using engagement as a means of measuring ad viewability may be easy to understand and explain to brand marketers, but it is far from the best method of estimating an audience. This is because the majority of clicks are not valuable and can be generated by fraudulent traffic. Clicks, viewable impressions and completion rates all come a poor third to performance-based measurement. Mobile game publishers and e-commerce brands have recorded "massive successes", despite the difficulties and challenges in measuring against performance.
