PPC to build a list?

The only question is how exactly do you build a list? Well, there are several ways, article marketing, joint ventures with other online marketers, and pay per click. Although by far the most expensive way, pay per click might easily be the quickest way to build a list that will pay you dividends month after month. Let's talk about how to make this happen.The first thing you need to do is to figure out your niche. You might already be working in a niche, or you might not have a niche, but if you're building a list, one thing you want to consider is your ability to sell your customers more than one product.
You see lists serve two purposes in internet marketing. One, they let you get your message to your customers more than once, so that hopefully, they'll buy on the fifth, sixth, or seventh advertising message. Two, (and this is the more important of the two), they let you sell your customers other products and more expensive products.
A prospect is in the best mood to buy when they've got the old credit card out and they've just input their number into your web form. That's actually the single best time to hit them with a complementary product (called a cross-sell), or a more expensive product (called an up-sell). Now, you can do this without a list, but the list only makes it work better!
It's five times less expensive to sell something else to a satisfied customer than it is to find a new customer!
So, your best bet for selling your more expensive products is to your already satisfied customers. This is, of course, assuming you have satisfied customers. So, you'd better not sell them junk the first go around!
A list, or in this case, lists, allow you to keep track of who bought what and lets you sell folks who've bought your introductory product more expensive products. Designing products that grow in price, completeness, and complexity is called creating a product funnel. If you really want to make money out of your list, you'd better give a lot of thought to this idea of a product funnel.
