Eyeblaster released a research note - “Search and Display: Reach beyond the keyword” (get it here). It’s a brief note with very interesting findings, particularly for display folks. Using Eyeblaster’s proprietary “Channel Connect for Search” (CC4S) product, Eyeblaster tracked cross-channel campaigns and determined the source of the conversion.
The note starts with a really good overview of the purchase funnel as it pertains to display and search (using a very relevant analogy to the yellow pages). The funnel diagram shows how display and search can impact the funnel.
In the diagram, Display is shown to drive the entire funnel from Awareness to Intent to Purchase while Search only drives Consideration and Intent. I’d suggest that Search can and does influence “Favorability”. Once a consumer is aware of the need, she will search for generic, higher-level terms, and search can show ads that will drive brand favorability. For example, I might search for “BlueRay DVD player” and could then see a search ad for LG and view LG DVD players favorably. Additionally, while it isn’t clear if they mean this in the diagram, display is proven to drive repeat purchase (via retargeting). Search is unable to directly drive repeat purchase.
As to the results of Eyeblaster’s study, it was found that:
“Overall, for customers who used both search and display, 72% of conversions arrived as a direct result of the displaychannel. Only 23% of the conversions were a direct result of the search channel. 5% were the result of display ads that were followed by a search.”
Eyeblaster caveats that the share of display vs search is “the result of budget allocation decisions made by the advertisers.” It’s probably safe to assume that Eyeblaster clients lean a bit more towards display than search, particularly those using CC4S. The extremely low number of “search after display” conversions differs pretty dramatically from prior studies I’ve seen, which I believe has to be due to the types of campaigns being used in the study.
The report then digs into the share of display and search conversions by vertical. This is great data and you can see a wide variety in share by industry vertical. Entertainment, CPG, Financial and Careers lean far more towards display while B2B, Travel and Retail skew towards search. I’m actually surprised to see careers sitting more towards the display side, since jobs seems like a much more search-driven category, but the data tells a different story.
What would be really interesting here, given Eyeblaster’s leadership position in driving display engagement, is to get a sense of the breakout of display conversions by attribution type. How are these display conversions being attributed? It would be great to break these conversions out into post-view, post-click and even post-engagement. I’m petitioning for a follow-up Research Note.
The key takeaway here is that display is an extremely important part of any marketing plan and can drive conversions on its own. We in display intuitively know that and evangelize it every day, but it’s great to see a study from an industry leader showing some numbers to back it up. Next step is to dig even further into these numbers and really nail the point home.
