I used to be in the domain parking business and parked pages can either be 1 click or 2 clicks. Below are examples of what I am talking about.
I see a lot of similarities between domain parked pages and lead generation pages. You have one shot at converting them and after that you never see them again. Generally, 2 stage landers are better for broader topics where people could be searching for a lot of different things so it requires two clicks to get them what they are looking for. And, when the traffic is more targeted you generally use a 1 stage parked page. Do many people use a similar concept with landing pages and if so does anyone have some examples they could provide?
