Lead tunnel, what do you prefer?

it can't be said readily what you are asking. It depends on the product, the niche, the audience and most importantly what is the business strategy here..

Any product can be promoted in any way known possible but that doesn't mean that it will do well. Some products may do well once you just pitched them. Some might need a little push. And some might need a whole lot of promotions and effort to get sales.
