I have been building my list in the water4gas niche for about 2 weeks now and get about 3 leads per day out of 100 or page views or so. I tried the pop-up box and did not get a better opt in rate. I guess this is about what I can expect for that landing page. Is that a good opt-in rate or not? I am not sure. I make plenty of sales from the landing page but hardly anybody signs up for my newsletter. Maybe there is some way to optimize your page to increase the opt-ins without detracting from your affiliate link that you of course want them to click on. I thought the hover ad would be the silver bullet but I think people may find it irritating. Does anyone have any thoughts on that? Half the time people never verify their address which I don't understand. Oh well...its slow going but we'll get there.
