I was recently looking for a method to create an audible alert when a a clients website has a visitor. I did eventually find a solution via a 2012 post by Mike van Rossum.
- Click and Drag this Visitor Alert! into your Bookmarks to your Browser
- Access Google Analytics & open Realtime Overview (Home – Realtime – Overview)
- Once the Realtime Overview is open just click on the “Visitor-Alert” bookmarklet.
Now your ready…anytime time you have a new visitor to your website and you have Realtime Overview open you will hear a ringtone.
