Since my ad is a site type what kind of traffic could turn my domain as invalid? This clarification would be wonderful for me so i could eliminated that kind of traffic for my site so they wouldnt count as non-unique.
If you embed your ad unit to the URL specified upon ad unit creation or to any other URL under the same domain then there is no problem. But if you embed it to sites from other domains or generate traffic directly from mobile apps, browser extensions, etc, then it won't be counted as unique because domain name won't match.
But can you please add option to create account?
Thanks for your feedback. Yes, this sounds like a good idea.
Do you think it would be sufficient to enable our users to get registered with their public email addresses? We'd prefer not to keep others' secrets (like private email addresses).
