(From tomas.fifer@outlook.com) Hi,

We're wondering if you've ever considered taking the content from romanofamilychiropracticandwellness.com and converting it into videos to promote on Youtube using Content Samurai? You simply add the text and it converts it into scenes that make up a full video. No special skills are needed, and there's access to over 1 million images/clips that can be used.

You can read more about the software here: https://turntextintovideo.com - there's also a link to a totally free guide called the 'Youtube SEO Cheat Sheet', full of fantastic advice on how to help your site rank higher in Youtube and in Google.

Kind Regards,
Tomas
