Why dont you leave that site on the free domain, buy 10 domains and set up sites about other cars - get them up to $12 a day aswell, then youll have $120 a day
No, don't do this. Google doesn't like traffic from these programs and could ban your site becuse of it.
I don't think Google would ban your site from using traffic exchanges. But anyway, I don't see the point in traffic exchanges. Although you gain visitors to your site from using it, you also lose visitors from using this type of service. I just don't see any benefits of using traffic exchanges.
You might want to listen to JenSense's first "Click This!" radio show, when her guest was Kim Malone from Google. She talks about dubious traffic sources, see: http://www.admoolah.com/blog/index.php/2006/05/jennifer-sleggs-new-radio-show-click-this/
I have not read or heard it, but I guess you are saying that you can get banned. It doesn't really worry me to much as I don't do traffic exchanges, auto exchanges, banner exchanges, etc. I only try and use the best forms of advertising. These include articles, submitting to quality web directories, ppc advertising in adwords and overture, seo, etc. As mentioned above, I don't see the point in doing traffic exchanges, but even though I don't see the point, I wouldn't have thought you would have got banned or anything like that as what about if your competitors just puts your site into the traffic exchange.
I've had some good experience with just building quality links and then google within few days has indexed over 20,000 of my pages. Now I have about 2000 uniques/day and generate about $25/day. Cheers! I'd post a link but I'm a newbie in this forum.
