  1. Hey, my name’s Eric and for just a second, imagine this…

    – Someone does a search and winds up at genie-electrique.net.

    – They hang out for a minute to check it out. “I’m interested… but… maybe…”

    – And then they hit the back button and check out the other search results instead.

    – Bottom line – you got an eyeball, but nothing else to show for it.

    – There they go.

    This isn’t really your fault – it happens a LOT – studies show 7 out of 10 visitors to any site disappear without leaving a trace.

    But you CAN fix that.
