the(G)thang, how many searchengines are there that will really deliver you the numbers ??
go.com -> gone
excite.com -> gone
voila.com -> gone
infoseek.de -> gone
lycos.com -> gone
northernlight -> gone
... the only searchengines that will get you a decent amount of free traffic today are, altavista and google. and it´s just a question of time until they will no longer give away their traffic for free, as we all know CMGI is in big trouble and google also has trouble to pay for their 6000+ cluster fuck. It´s kinda hard to believe your numbers, you´d be lucky if you get something like 20k out of them per day ... anyway, you wanted to know some numbers.
you can expect to get a 30% clickoutratio, pretty easy because all the surfers gets is a bannerfarm (if you manage to hide your spider site). the other 70% will be victims of your console hell ... so sooner or later you´ll get 90% to your sponsors, by click or forced. as of signup ratios, you´ll be looking at anything between 1:600 - 1:1500 !!
