My advice to people starting in media buying is to simply start small. By small I mean local, some of the highest CTR of any ads I've purchased have been on local news sites. If you live in America go to KGB Channel 9 news and click the advertise with us link, then try to find a local based offer, or just make an ad that says (for example) Great new auto-insurance deals in Iowa! Then have the ad go to your auto website that basically has a CPA offer for auto quotes integrated into it. Anyone else tried smaller market media buying?
