how much you'd pay for each search engine hit (you pick the keywords)
 

For example, if you have a mardi gras site, how much you'll pay for "nude mardi gras" "nude spring break" or someting like that hit ? 0.5 cent .010 cent

for penis enlargement ?
for webcam ?

and etc...

"$29.95 pay fat porn"

$1.00/hit.

Nothing
I do just fine tweaking my metatags :)
