I'm getting so many Ads on Facebook about coaches who can help us create a 7 figures business or close clients using their systems.
The term "systems" is overused to say the least. In the context of the Facebook ads you're seeing you can consider their systems paid webinars, videos, ebooks, masterminds and/or a combination of any (or more) of these.
The systems that business coaches use vary greatly from no system at all to being part of a high cost/high-value group like the one run by Taki Moore (coachmarketingmachine.com). I am very familiar with Taki and what he teaches and think it is a fantastic "system".
The bottom line is, the Facebook Ads are nothing more than a targeted billboard.
Cheers,
Ryan
