## Services — Digital Advertising

Display ads that convert

Blackbook designs display ads that capture attention in a split second. We produce HTML5 banners, rich media and animated formats that work within the technical constraints – and exploit them instead of fighting them.

AI is part of our banner production – from automated format variations that scale one idea to 20 sizes, to dynamic content layouts that adapt to the audience.

## Attention has a deadline

### Display advertising and HTML5 banner production

A display ad has less than one second to stop the eye. There is no room to explain – there is room to hit. We design banners that communicate the message in the time the format allows: sharp visual hierarchies, precise animation timing and a click incentive that feels natural.

We know the specs for Google, AdForm, Campaign Manager and the major media agencies. File sizes, loop limits and fallback frames are conditions we design into – not problems we solve afterwards.

## Scalable quality

A campaign rarely lives in one format. We produce campaign packages that keep the visual expression consistent across top banners, skyscrapers, wallpapers and interstitials – without quality dropping with the sizes.

**What we deliver:** HTML5 banners · Rich media · Animated display ads · Campaign packages · Top banners & skyscrapers · Wallpapers · Interstitials · Retargeting banners · Dynamic content

## For brands that want to be seen – even in the sidebar

We work with retail, pharma, eCommerce and B2B – companies that use display as an active channel, not just overflow space for messages that did not fit elsewhere.

If you have a campaign that needs producing in format, [let's talk about your project](https://www.blackbook.dk/en/contact/).
