What weight should my banner creatives be?
From February 2020, ExoClick is changing the maximum weight that it will accept from advertisers for all banner creatives to 150KB, this is to ensure that banner ads are aligned with the IAB’s industry recommendations as well as Google ones. This applies to ALL types of banners.
Maximum Banner File Size Changes:
Current Banner Maximum File Size: 1MB
New Banner Maximum File Size: 150KB
Please note: All existing campaigns will keep running normally for now, even if some banners are over 150KB. However, advertisers will NOT be allowed to upload new banners that exceed 150KB for new campaigns from February. Advertisers will be given until April 1st to update all their creatives, at which point, all banners over 150KB will be disabled from the system.
Recommendations/Tips:
Use MP4 Video Banners instead of heavy GIF banners. This improves quality.
Use JPG instead of PNG. PNG is a heavier format and is no better in terms of quality than JPG.
Here are some articles to help you optimise your banner sizes before uploading them to campaign variations:
