Firstly you have to ask yourself, "Are all surfers the same?" Then think it through.
My
There are three kinds of surfers. Ones who buy, ones who might buy and ones who will never buy.
The ones who buy are not first timers, they've bought in this niche before, they know, understand and love the niche. THEY NOTICE EVERYTHING.
The ones who might buy have a good understanding of the niche, they know what they like and if you hit them with the right stuff they will buy.
The third ones don't give a damn and are happy to surf the free porn.
The bigger question is does the webmaster know the details and buy accordingly?
I know I'm an arrogant bum, but hear me out.
I learned to shoot in a tougher market them the Internet. The work had to be right and the competition was tough. You make a mistake on a set and you did not sell it, you get it right you make $3,000 for a solo girl set and upwards.
Now go around the Net and see what prices are being offered for solo girl sets exclusive. There are shooters boasting they can do 15 sets in a day and for $200 a piece. What attention to detail do you think you get for that price/quantity, or how the model and shooter are feeling after 4 hours?
Many webmasters put a lot of emphasis on things they understand and tend to ignore things they do not. They concentrate on the layout, text, speed, quantity, quality of the site and ignore the porn. Because they understand the first things and not the last.
Do you really think the surfer looks at anything if the porn turns him off. do you really believe he will click on a link if it says
HOTTEST BABE IN THE WORLD WILL FUCK YOUR BRAINS OUT if the picture says "I'm bored, ugly and want to go home"?
Get the porn right and see the difference.
