A selling process for any product, not just membership sites must be REALLY fine tuned.
When checking other pages, it is REALLY easy to see flaws and where these sites miss the point.
Now, this means that the selling process must be super fien tuned.
The offer must be clear and compelling
The page must be clear
Too much time on the design is a turn off - It means that this is where the energy was put...
But not enough time + overloaded pages are turn offs too!!!
No need for flashy graphics, simply need for clarity!
Again, simplicity is key!
