I keep getting solicitied by Traffic Swarm. Their scheme is that they pop up a window when you leave a site. The pop-up contains ads. Its like a banner exchange program but is a pop-up exchange program. The thought is that if a surfer is leaving your site, there is nothing lost by spaming them with a pop-up. So if I had this on my site, as some one tried to leave, I would pop'em. THe pop up would contain ads for other sites, not my own. Likewise those other sites would have the same deal except perhaps there pop-up would contain my ad. The more users that leave your site and receive a pop-up the greater number of times your ad appears in the pop-up of other sites.
My concern is that search engines will probably frown on this activity and might even ban a site that uses this form of advertisement. Then again, many sites hit you with pop-ups when you first hit their site. THey offer free shipping or want you to know about some special. I don't like those any better, but there does not seem to be any repercussion from using them
Search engines won't care but your users will. It is highly unlikely that you'll make any money out of them anyhow if they are ppc. Just think: what's the first thing you do with a pop-under which opens up when you leave a site? You close it, hopefully before it finishes loading.
I too hate....HATE... pop ups. But being a webmaster I tend to be sensitive to such things. So I thought I would be open minded and give it a try. If no traffic came from it, the plan was to quickly remove it.
Well, I put the code on last night and gave it a try. Turned out that instead of a pop-up on exit, a pop-up appeared for every page you surfed on my site. I quickly removed the code and sent a message to their tech support.
Get this, they said that there code does not do that. Ha!
