Hello guys, its not just your ads but in general google html validator is often showing me error, but I found out that that in campaigns these errors doesn’t exist. So does google have any validator before adding playables to real campaign?

Hello Paul, Most of the times users write us asking about this one - [HTML5 Validator](https://h5validator.appspot.com/adwords/asset)
But to be honest google validator never works properly. What we do is we test our playables in campaigns directly (creating campaign for 1 euro and let the verification of assets pass - it always works).
Second option is to build of other adnetworks and try their validator, for example unity or mintegral - the latter has great online tool for verification [Mindworks-Upload-Playable Testing](https://www.playturbo.com/review)
But in any case, don’t be afraid to write us directly or here for any questions, we are always here to help you out.
