Hey guys,
After running a bunch of mobile gaming offers with varying degrees of success and reading comments from others here, it's become obvious that perhaps more than anything, high-ctr custom banners are crucial for campaign performance in this vertical.
I'm a person who procrastinates and drifts from one thing to another unless I have a very rigid process to stick to. Because of this, I am designing a system for creating a testing gaming banners.
My first step is to prioritise testing those elements that have the largest potential impact. I break this down broadly into 3 sections:
- Banner style / layout
- Imagery (whether from promo material, other banners, in-game screen caps etc.)
- Text angles / cta
I would be interested in hearing from anyone who has had success in mobile gaming on which of the above they consider to be the best place to start.
Thanks 
Zeno wrote a bunch of tips about making gaming banners over here: http://stmforum.com/forum/showthread...l=1#post140547 . They're intended for Facebook but will work for mobile too.
Mr Green's post on mobile banners here will also be useful: http://stmforum.com/forum/showthread...late-inside%29
I'd recommend that you split your text section up. CTA, headline, and any other text on the banner should be considered as separate elements, not all together as a single element.
In addition, I would strongly advise you to consider angle entirely separate from other elements, and indeed from the single banner. Angle is hugely important.
Hope that helps!
Thanks Caurmen, very helpful 
Would you suggest testing angles first before playing around with imagery and banner layouts?
The reason I ask is because many gaming banners seem to rely solely on the imagery with basically no text apart from CTA.
Do both at the same time! Definitely test angles, and then test different banner types within them.
Also - are you sure those no-text banners are converting? A lot of the stock gaming creatives are very short on words, but stock creatives tend to convert terribly.
