So does display (ie banner) advertising work? There’s always a lot of discussion around this (and we’ve been looknig in to this with our Oohgle campaign) - is it brand building? Can you measure the ROI?
Comscore have just done a paper on this - you can request the full copy here - and they found the following
It’s clear that display advertising, despite a lack of clicks, can have a significant positive impact on:
- Visitation to the advertiser’s Web site (lift of at least 46% over a four week period)
- The likelihood of consumers conducting a search query using the advertiser’s branded terms (a lift of at least 38% over a four week period)
- Consumers’ likelihood of buying the advertised brand online (an average 27% lift in online sales)
- Consumers’ likelihood of buying at the advertiser’s retail store (an average lift of 17%)
So essentially - the display ad doesn’t result directly in a click, bit can have a big impact on the number of searches performed and the clicks from search results.
Low click rates on display ads are not evidence that the ad hasn’t had an impact on consumer behavior - the ads aren’t present in themoment of purchase intent - but display ads have a significant impact on interest in the product or service which is realized at some later date in the form of a site visit, a search query, and possibly on online or offline purchase.

It shows that display ads can have a significant lift in site visits for up to 4 weeks after the ads have run.
One of the most interesting findings is:
….it must be remembered that the reach of display ads is typically much higher than that of search ads. For example, in the studies conducted by comScore, approximately 81% of the consumers who saw an ad received only a display ad, while a much lower 8% received only a search ad.
So - this reinforces conventional wisdom which says that:
media works best when multiple programs are used together, and we do indeed see clear synergies between search and display. Both in terms of the impact on buyer penetration and dollar sales (per thousand consumers exposed), it’s clear that the combination of search and display together is greater than the sum of the impact of display and search ads separately. The synergy is notable.
This fits in very well with the research we’ve been conducting with Posterscope on the Oohgle campaign to demonstrate how display (particularly OOH) drives search and brand awareness.
