How long does a review of a site take? This is important when doing a review. Comparing what a film or food critic does with what 90% or more of pornsite reviewers do is comparing apples with baked beans.
A film or food critic eats the whole meal or watches the whole film. Unless it sucks and they walk out. A porn site reviewer reviews and gives marks on the menu, layout of the site, number of films/sets, DL speed and zipped content and little else. So reviewing a 30 day membership in anything less than a couple of hours is worthless. IMO
He has to sit and watch 4-5 movies and the same number of sets. The customer will be watching a whole lot more. He needs to know what makes the niche he's reviewing works. He needs to know what is good content and what is bad. It's far more important than the number of images or length of a video. He needs to look at the content and ascertain how much of it is all the same. 50 set and 50 videos all the same get very boring after 30 days. As does 500 of both.
We sell a product for a months consumption. We need customers to retain or/and upsell to other sites we own. AND we want to keep buyers buying. The strength of what we sell has never been more important.
