(From eric@talkwithwebvisitor.com) Cool website!

My name’s Eric, and I just found your site - drstopa.com - while surfing the net. You showed up at the top of the search results, so I checked you out. Looks like what you’re doing is pretty cool.
 
But if you don’t mind me asking – after someone like me stumbles across drstopa.com, what usually happens?

Is your site generating leads for your business? 
 
I’m guessing some, but I also bet you’d like more… studies show that 7 out 10 who land on a site wind up leaving without a trace.

Not good.

Here’s a thought – what if there was an easy way for every visitor to “raise their hand” to get a phone call from you INSTANTLY… the second they hit your site and said, “call me now.”

You can –
  
Talk With Web Visitor is a software widget that’s works on your site, ready to capture any visitor’s Name, Email address and Phone Number.  It lets you know IMMEDIATELY – so that you can talk to that lead while they’re literally looking over your site.
