Help with Native Advertising

Hello guys, I need some suggestions related with Native Advertising. Our competitors are running the next funnel: Comparison > Presell > Home Page (Product Page) > Checkout.
So we tried running the exact same thing just without the Presell page, like: Comparison > Home Page (Product Page) > Checkout; and we faced issues because of the presell. Are there any suggestions about how to run these ads successfully without having a presell page for every product?

Customized Home Page (Product Page).

But I guess that's the same amount of work like having presell page so not really what you're looking for.

Presell pages are most effective, they are simply designed to understand your product and help them into your call to action. They are also easy to make. You need to know what information can you put. I think add the presell page. So create a presell page similar to landing page and try to solve the problem related to that

I understand you both, but we want to try making a successful running funnel without presell pages. We're doing that at the moment but we're not having some good results. Any idea on how we should make it convert better without having presell pages?
