(From daddario.fern@gmail.com) Hi,

We're wondering if you've ever considered taking the content from higleychiropractic.com and converting it into videos to promote on social media platforms such as Youtube?

It's another 'rod in the pond' in terms of traffic generation, as so many people use Youtube.

You can read a bit more about the software here: https://bit.ly/326uaHS

Kind Regards,
Fern
