How the length of a sales page is good for conversions?

[Mjlivera]

Hello webmasters,
I'm pretty new to affiliate marketing and online business, and I'm trying to select a product to promote from affiliate program providers. I decide to try coaching and traffic niche.
Just starting steps but I'm facing a problem. Some of the products on my sale page need to look pretty and I want it to bring as many conversions as possible.
So, my question is: How long should a sales page be for conversions or getting new sales?

Your suggestions would be appreciated!

I think it should cover all the main factors that the customers need.

In my personal opinion, I would like to read a sale page around 300 to 500 words but must be enough information.

The general rule is that the more
the product costs the longer the sales page
has to be. That is because it will take a lot
more for you to convince people to fork
out large sums of money.

However, if what you are promoting is cheap then
a short sales page will do.
