I have been able to get a really good ROI so far, but Myspace pretty much refuses to let me scale my campaigns. It seems no matter what I raise my budget or bid prices to, there is absolutely no change in impressions. I have about 10 different campaigns running all to the same offer with the same ad copy, each campaign has a CTR between .1% and .16%. My budget for each campaign is $10k, and they are all set to run for 3 days.
I'm continuously pausing and running campaigns; getting the more or less the same amount of traffic daily. Just give the platform some leeway when starting campaigns - roughly an hour - so that there's a sufficient flow. Also, have several campaigns with the same creatives. At least a few will get clicks with the initial load of impressions. MySpace will then keep favouring those particular advertisements and send you clicks throughout the day.
I'm doing wonderful on it =). I don't know why you guys are hating- guess you should just give up on it and stick to adwords.
What do you guys do once the ad is approved but wont kick start at all for a couple of days.
