Been doing well with search PPC, so I decided to reinvest that into trying a bunch of different kinds of traffic buying. After all scared money doesn't make money. Here's just the ones I tried personally in the last week and what I thought: (1) JuicyAds - With a $50 deposit, buying spot ads on websites also means getting lots of repeat views and non-geo-specific traffic. Still it does convert. Haven't tried RON. (2) TrafficJunky - The best I played around with. $25 deposits, low CPMs, got conversions. (3) Clicksor - put $20 in, got a phone call and the woman wanted me to pick keywords. I asked to do it later and they started my campaign anyway. paused it, haven't gotten around to testing the quality of the traffic, but it's an older name can't be all bad. (4) Adblade - couldn't stand for the $0.50 minimum CPC, but the $0.15 mobile CPC might be interesting. Haven't actually tested. (5) Adclickmedia - weird flat-rate CPC banner display system. no clicks yet. (6) Zeropark - solid domain redirect and popup provider. (7) DNTX - solid domain redirect and CPC ("one click") provider. (8) CPMFUN - funky little cpm banner display company with popups and iframes. definitely real (to the extent that the owner can ban botters) given the moaning from their publishers online about payouts etc. bought a popup package and couldn't see that it's definitely bots, but no conversions either. (9) Mctraffics - absolute shite, some scam operation out of Russia that mocks you with its obviously cheesy graphics and typos... yes I was in the buying mood and tested it, definitely bots, dishonestly denies refunds, save yourself the trouble. So that's what I tested, next on my list are some of the ones with higher minimums: Exoclick (adult), SiteScout (banner display), and Mediatraffic (PPV). Not even sure I like PPV in general, honestly, so may not ever try LeadImpact or TrafficVance, despite their good reputations. Last but not least, I will probably try adwords with some decent landers when I get around to it. Just thought I'd try some of the minor players first to see if there are any hidden gems. Happy testing.
