"What is the accepted standard flow to a porn site, top to bottom."
Love ya Amp, very good question and out of respect I must answer you
Accepted standards for Pornsites.
Humm.
Well I think all "Standards" for pornsites is pretty broad but I am sure it certainly concerns the business model at hand of course.
I will take a subscription site tour for an example of "Standardised" since it is seemingly overly standardised in my opinion to a point of hysteria. I believe the way of 5 page presentation hallmark tours are over. Its 80's porn style with crops fades and textures must end. I believe your selling the content not "Shock and Awe" of perfect symetry and colors IE " Graphical Cosmetics".
Firstly from the top of the page, I believe "The deal" at hand needs to be mentioned. In a big way.
FREE ACCESS or things along those lines.
"Get ACCESS FOR 66 CENTS A DAY!" or What ever. I think that what ever your selling is the most important in a tour. The click was already delivered to the tour via something that appealed to the visitor, these days most often I think Galleries are selling sites primarily which contain the girls or niche that the click liked and wants more of.
Then again many other considerations if possible should be taken and accounted for before developing a tour as to where traffic sources are mostly comming from.
After the deal follow with the site name. The domain preferably of course.
Below that a Members button "Members Enter Here" Then another Get access button next to it.
Content. Sell the girl and sites features. Tell the potential client "WHAT THEY GET!" Show em the chicks also but grace it with the matter at hand with casual text
EXAMPLE:
"WE GOT THE FULL COLLECTION OF SANDRA! SHE 19 YEAR'S OLD AND HORNY! 500 PHOTOS PLUS 10 DOWNLOADABLE VIDEO CLIPS!".
I like reading about a girl sometimes on a tour. A little info is always good about the chicks inside.
Bottom Offer a Next page, and to the right of it a ACCESS NOW stating the deal.
With the intelligent use of animated GIF's you can use them to attract attention to once again the matter at hand.
You know as well as I do that this is basic. but then again. Standard.
