I need help - clickbank products

I work with reddit traffic but I've been told that clickbank offers improve the possible conversion rate if I try to create a pre-lading, but I'd like to hear from people who know what ideas they have about it.

For example, I really like the GlucoTrust product and it has a nice sales page, but I thought about creating articles and driving traffic to a blog and that the links are in banners. I don't know if it's a good idea for pre-landing
