Effective display advertising
Having been involved in a fair few consultations regarding online display creative, I thought I’d share a few nuggets with you.
People aren’t interested in a story
You need cut-through, so get to the point. No more than 5 frames of animation; less if you can manage it.
Show me the money(shot)
Your incentive should appear fairly soon in your animation frames in order to grab attention. Money off, vouchers, a specific offer – whatever it is, do it quickly.
Know your enemy: banner sizes
There are a set number of specific banner sizes that you can use to get your message across. Certain formats will allow you to do more: others will allow very little room for messaging.The IAB set out guidelines for ad unit sizes, as follows:
Banners and Buttons
Skyscrapers
| 160 x 600 IMU – (Wide Skyscraper) | 40k | :15 | |
| 120 x 600 IMU – (Skyscraper) | 40k | :15 | |
| 300 x 600 IMU – (Half Page Ad) | 40k | :15 |
The takehome? A teeny-tiny 88×31 space will NOT allow you to tell a lovely, 21st-century-BT-esque-family story. Choose your sizes/locations wisely, and apply the ‘Storyboard’, ‘Moneyshot’ and ‘In-situ’ rules appropriately.
Know your enemy #2: in-situ
You know when you look at banners on a designer’s screen, or printed out on lovely pristine white presentation boards? Yeah – that’s NOT how people will see your ads: they’ll be in amongst other content – stuff that they’re actually interested in reading. Your ad is, essentially, a distraction. Make it a good one.
Who are you?
Remember: people don’t know who you are. ALWAYS include your company logo, and if at all possible, a persistent URL. People may not click on your ad, but display can be used as a Brand Response mechanism as well as Direct Response. Therefore, including your logo and a URL can only help brand recall.

Very Comprehensive George. Simple and to the point just like good creative should be. Only point I would like to add is in the case of Financial services display ads – make sure you are clear on the product being promoted – this will ultimately help with conversion through to sale.
@Sian Birks
You make a very valid point! Thanks for the comment.
As always George an interesting read.
We’ve just been though a creative review and all these points came up. As ever we faced the issue of offline creative being shoe-horned into a diplay space.
Again, from a financial services perspective there seems to be debate around the use of T&C’s, actually in the creative for price saving propositions! Your thoughts?
Hi Mark – thanks for the comment
FS, as you know, tries to be as squeakily-clean as possible in terms of a) not mis-selling products and b) keeping the FSA happy that that is the case. Striking that balance between creative & compliance is always tricky: one runs the risk of neutering marketing messages entirely and being left with something that’s completely uncompelling. I personally feel it’s not the job of display ads to outline all the risks – that’s the job of the main site.
There are, I suppose, a couple of points to make regarding not adequately providing all the info/caveats/assumptions in price-saving creative:
* You risk customer complaints, and then all the associated TCF issues
* The quality of customer that clicks through could go down if you don’t disclose certain things (i.e. “saving based on a 60-year-old male with 10 years NCD”) – and that in turn will affect…
* …conversion rates
However, I feel there’re compromises that could be made:
* Ensuring the customer lands on a page that DOES adequately convey the caveats would help (even though the display CTR/ROI could still suffer)
* Engage in some heavy ad-targetting for the creative (I appreciate this is not always possible, but that could offset the risk of poor-quality-customer CT?)
* Perhaps utilise some different ad unit formats (flyouts, perhaps) that could allow more space for creative, but also for the dreaded T&Cs.
Specific ad unit effectiveness isn’t my forte, so someone more knowledgeable would be better placed to answer that last one!
