I bet you could make a fortune
It costs around five cents per piece.. $50-$60 per thousand, usually..
I mean, hell, compare that to direct mail .. junk mail probably converts like SHIT and costs MANY TIMES as much
Highly targeted search traffic costs alot of money
Last time I used it, I tried buying low traffic low price keywords.. worked well until they refused to send me traffic because of "low search volume" IE: they couldn't charge me enough. .. sigh
Man if you can stay ahead of the cost you can make a FORTUNE with search traffic
I'm hopeless with SEO so free search traffic ain't there ... LoL
