I tried FB, Google, and Amazon Ads with an IoT Product I Develop. FB wasn't good. Instagram too. Even the ads I get as a consumer is bad. Instagram seems good for hyper local services though. Amazon ads seems good in terms of sales compared to Google but the cost ends up high. They're essentially double dipping since you have to pay for FBA fees and Ads if you choose to. I plan to just spend on Google Ads since it's DTC so there are no retailer fees to pay for. As a consumer I like both Google and Amazon. I definitely buy more on Amazon and the ads are pretty effective in bombarding the customer, but the quality of the products from Google is much better. Partly because Google (and Youtube) is a great research tool when deciding which product to purchase. Also, a lot of the Google search results point to Amazon or other Shopping Portals. Also article doesn't mention Oculus at all :$
