I am somewhat new to affiliate marketing and I am not sure if I need a landing/squeeze page when I am using ppc. I am not interested in building a list just yet.

It all depends on what your end goal is in terms of your marketing efforts.

A landing page is that extra piece of real estate that you could use to help you get the sale.
If you need more space to persuade a potential customer to make a sale, use landing pages.

I�ve made sales doing straight links & landing pages.

When you are ready to collect names and addresses for a list, a landing page is a great place to put up a subscription form.
