Hi RainMaker,
Actually, driving traffic to several websites, I use a combination of tactics. In regards to PPC, the traffic generated is very specific to what I want to accomplish (ie. collect data, gather market worldviews, test AD copy, etc), and not for casual viewing.
Talking about converting visitors to paying customers is a new thread in itself

So in short, before any monetary transactions are made, I would have already tested the copy, tested the Google Adwords Campaign, found the keywords that people are using to search for my product(service), and developed a marketing plan that answers the questions gathered from my previous campaign.
So, if we're talking about converting traffic, I have already used the data to tell me if there was a market in the first place. As a direct marketer, I make sure there is a market that wants the product, and then I develop the product. So, no problems converting traffic
When I think of resistance, specifically to the product, I think "FANTASTIC!" Once I know that my product (service) generates resistance, it tells me that my product is "shooting for the edges." WHICH I WANT.
From there, it's a matter of finding the people (early adopters), who want the product, are enthusiastic about the product, and cater to them. These early adopters are the key to my marketing strategy.
Sorry, more theory this time than tactics.
