(From eric@talkwithwebvisitor.com) Hi, my name is Eric and I’m betting you’d like your website bretowchiropractic.com to generate more leads.

Here’s how:
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 signals you as soon as they say they’re interested – so that you can talk to that lead while they’re still there at bretowchiropractic.com.

Talk With Web Visitor – CLICK HERE http://www.talkwithwebvisitor.com for a live demo now.

And now that you’ve got their phone number, our new SMS Text With Lead feature enables you to start a text (SMS) conversation – answer questions, provide more info, and close a deal that way.

If they don’t take you up on your offer then, just follow up with text messages for new offers, content links, even just “how you doing?” notes to build a relationship.

CLICK HERE http://www.talkwithwebvisitor.com to discover what Talk With Web Visitor can do for your business.
