All Social media platforms are effective. It's obvious some will be more than others, but at the end of the day, they all are effective. What I'm noticing is that some people are not prepared to spend money for advertising on Facebook and when no one clicks on the free ads or they get zero sales, they conclude that the platform is not effective for advertising. Yes, I agree; Facebook is not really effective to get sales...for free ads. I guess if I want to see Facebook's true colors I'll put my money where my mouth is.
