Just thought I'd share something that I have been testing out. Recently I added a voice (wave) file to one of my website pages as a test. As cheezy as it sounds, the results have been quite amazing. My bounce rates have reduced by around 40% and my registrations to that page have increased by three times what they used to be.
I'm now going to add some more wave files to my site to see if I can get a better measure of these results. Has anyone else here tried this?
