| 107.175.92.118 | attack | (From eric@talkwithwebvisitor.com) Good day, My name is Eric and unlike a lot of emails you might get, I wanted to instead provide you with a word of encouragement – Congratulations What for? Part of my job is to check out websites and the work you’ve done with svchiropractic.com definitely stands out. It’s clear you took building a website seriously and made a real investment of time and resources into making it top quality. There is, however, a catch… more accurately, a question… So when someone like me happens to find your site – maybe at the top of the search results (nice job BTW) or just through a random link, how do you know? More importantly, how do you make a connection with that person? Studies show that 7 out of 10 visitors don’t stick around – they’re there one second and then gone with the wind. Here’s a way to create INSTANT engagement that you may not have known about… Talk With Web Visitor is a software widget that’s works on your site, ready to capture any |
