Google Ads vs CM360 HTML5 Creative Specs
Many design teams compile a single HTML5 creative ZIP and expect it to upload seamlessly to both Google Ads (AdWords) and Campaign Manager 360 (DoubleClick). However, these platforms belong to different branches of the Google ad ecosystem and have distinct technical limitations.
Specs Comparison Checklist
| Feature | Google Ads (AdWords) | CM360 / DV360 |
|---|---|---|
| Max ZIP File Size | 600 KB (Strict limit) | 10 MB (Permissive) |
| Max File Count | 40 files limit | 512 files limit |
| External CDNs | Google-approved CDN list only | Allows custom CDNs |
| local Storage API | Strictly forbidden (Policy block) | Permitted on most placements |
| Exit tracking method | clickTag variable only |

Trafficking Takeaways
If you are building campaigns targeting both setups, design your assets to fit the stricter Google Ads specs. That way, a single ZIP file can be used universally without modification.
