In a previous article, "In the Mix: Search in the Overall Marketing Mix," I outlined how ups and downs in search activity and success metrics are often related with activity in other media channels, such as TV, radio, print, and online. One common finding is that as media activity increases, impressions and clicks go up as well.
In reaction to this situation, we often just expand the budget to ensure sufficient capacity and exposure to our search campaigns. Keywords are often added as well, that reflect any unique phrases conveyed in the other media. Destination URLs are adjusted, etc. End of story? Hardly.
The top-of-mind reaction to external media pushes is to increase bids and budgets. If a brand, product or service is being made more visible via TV or radio, for example, it is a simple corollary that a client wants more visibility (read: more widespread and prominent positioning) in the search results. But that approach can get you into trouble.
Adjusting Search Bids to External Media
We already know that an increasing number of clicks will drive up costs. Bid (position) boosting will drive up costs even further. And for what? Our research on the timing of external media activity and search activity shows that click-through rates increase no matter what position the search result occupies (OK, so the cost per click may come down as your quality score goes up). But conversion rates may actually decrease.
Increasing budget + increasing bids + increasing clicks + lower conversion rates means exploding costs per conversion and declining ROIs. What explains this phenomenon?
Simply said, the media blitz oftentimes drives brand awareness to less "qualified" leads. Think about it this way. If there’s no external media on your brand or product/service, and someone does a search, they are probably very intent on finding an answer to a specified question. In contrast, in the post-media blitz phase, all sorts of people suddenly are piqued about your brand or product/service, even those that were marginally interested earlier. Those "activated searchers" tend to convert at lower rates.
That is not to say that external media NEVER drives "highly qualified" searchers through the search conversion process. Sometimes conversion rates do increase with a coordinated media blitz (especially if the media has a very strong call to action, like "limited time offer," etc.). Nor does it mean that lower ROIs are necessarily bad. Perhaps the goal is to increase brand awareness. But if you’re counting the dollars spent against the dollars coming in, it is quite likely that increasing your budget and bids will be counter-productive.
Less is More
In fact, one way to react to an external media blitz may be counter-intuitive: lower your bids (position) and keep your budget the same. When people search for you or your products/services, they are just as apt to notice you in the lower position (as before the media blitz). That lower position and/or lower CPC will stretch your budget, yield more conversions by virtue of greater traffic (impressions and clicks), and boost your ROI.
Am I advocating "going dark" when there is an external media blitz occurring? Certainly not. Several studies show the simultaneous presence of a brand/product/service in multiple marketing channels is beneficial, and often produce the so-called "1+1=3" effect, where the impact of more than one marketing channel on sales is greater than the sum of their independent parts.
But what we don’t want is to have the 1+1=3 equation apply to your cost per conversion. Map it out. Track your CTR and CPA over the time before, during, and after the media blitz. Consider your rank and total conversions at the same time. Figure out the tradeoffs and identify where search best fits into the mix.
The relationship between external media activity and search budgets/bids is not a simple 1:1 strategy. You need to carefully examine historical data to see how media activity has influenced your search campaigns. What happened to click-through and conversion rates? How many more conversions did you get? What happened to CPCs? And what happened to your ROI? You may be surprised by the answers you get, and that untying the knot of media mix and search requires more thought and effort.
