I have a friend who works on ads for video games mostly. Their company uses Google and Facebook for the majority of those spend, which one has better value for money tends to change every time I ask them. They definitely made FB ads work well for them for many years.

In addition, I’ve noticed people here commonly tell stories about how X’s ads never work work. I find it ridiculous. All of those digital ads definitely work for many companies, even if they don’t work at all for others. Ads is a competitive market. If your ads don’t work, it doesn’t say much about the platform, and may say more about your ads/product.

(Disclaimer: FB employee, but I don’t deal with ads)
