I'm looking to test out a handful of ads on a couple of to-be-determined sites that get ~50k pageviews per day. Instead of asking someone for an easily faked screenshot, would it be smarter to keep the ad on my server and have the publisher just access it from there for each pageview? That way I could change things at will to experiment ad copy, while getting a clearer view of the impressions. Obviously it's not a foolproof guarantee, but has anyone done anything similar? Thoughts? Thanks, TSE
