We advise using the Google AdWords HTML5 validator to check the HTML5 ads before submitting to be served in any campaign, by clicking here.
For a full list of ad sizes and specifications please see the IAB guidelines click here.
We can also use third-party ad tags. The actual ads files trafficked through the tags must adhere to the same requirements as listed for static/HTML5 ads (i.e. size, format, animation duration, etc.).
Some ad exchanges require the ad server to be a certified third-party vendor such as Google’s Ad Exchange (click here).
Here are the general specifications for the ads trafficked through third-party ad tags:
|Initial load size||150 KB maximum is recommended for the fastest initial load time
|Viewer-initiated load size||Up to 10 MB per interaction.2.2 MB maximum total load size is recommended for optimum performance.|
|CPU capacity usage||For an optimum viewer experience, third-party served ads must not exceed 40% of the central processing unit (CPU) capacity of a viewer’s computer. Common causes of high CPU usage are continued animation, heavy animation sequences and animation that surpasses the 30-second limit. If applicable, then you can use the Task Manager feature in Windows to check for compliance with this rule.|
|Animation length||Maximum host-initiated play: 30 seconds
Maximum user-initiated play (click required): 4 minutes
