If you think back as far as 2010 or even further and then I asked you a question; have you bought any Facebook products, software or plugins or eBooks would your answer be yes; well if so, you may find a lot of the stuff out there being purchased still is outdated and doesn’t work anymore?
The reason being is since 2010 and to date Facebook have made regular updates of functionality which basically have turned many people away from using their social platform, especially marketers...
