New to Cape Check & Go: we’re taking the work out of manual ad quality checks with the new ‘Analyse’ feature: automatically check if your video, image and audio creatives are in the right format for Google DV360, Google CM360, YouTube, Disney+, Netflix, Amazon Prime Video and The Trade Desk (with more platforms being added soon).

Manually checking ads is too slow — having to manually check them against hugely complicated, varied and often confusing ad specs — the new ‘Analyse’ feature makes it much faster. Check creatives against ad platform and CTV specifications, helping you make sure ads will be accepted, so you can stick to campaign launch timelines and make the whole thing more efficient and way less stressful.

This feature will be available to users who are signed up to a free account, so register now or log in.

What we are checking

Here is a list of what we are currently checking against with our Analyse tool:

What’s next?

Over time, we will be listening to our customers and updating how we test and what we are testing for. We have been testing using AI to get even better results based on platforms with very broad or complex specifications, as well as best practices and effectiveness. Keep up to date with product updates from Cape Check & Go, or the rest of the Cape.io.
