Boy, I must be the world's worst searcher because I'm sure you have discussed this by now (but I can't find it). I want to have several products at clickbank. I have one account, have 2 products now and have the one landing page and the 2 thank you pages. But how do you deal with the landing page? Do you have it basically be a list of the products, which people then click through to go to a particular item's sale page? And if so, do you think that's a problem? I hate to add an extra step for buyers if I don't have to. Or am I just being too cheap, and should instead have multiple accounts?
I think the answer depends on what category of your products is. If they are all similar, then you can absolutely put them together. However, if they are diverse, I'd suggest to put them in different places for catching separate targeted customers.
