Why are sales/info pages all the same

I find it funny when you aren't actively seeking any sort of product that sales page just pop up all over the place.

Worse still, they all look the same.

I just copied this from another thread [i can't submit links cause i only have 5 posts : )]

As soon as I see a page like this i know exactly what it's doing. Why do people create the same look and feel for these pages when by now, most people know exactly what they are for.

For me, if i'm looking for some info product and I come across these designs i'm turned off straight away as i know the revenue is probably forged. I know that the person selling the product is trying to make money and tell me how rich they are - when they may or may not be. Everything about it to me is untrustworthy.

I know the design works, or has, but where did it come from - who said that all info/sales pages need to look like this or is everyone buying templates?

Can anyone recommend a product that is effectively the same, but their method of design is different? I wonder the success rate of various designs and which ones actually turn more profit.

When and if I ever decide to create a digital product to sell - I won't be looking at these pages for inspiration. Surely if these people are making 6 figures, they could hire a designer to make them unique..hahaha...hmmm?
