That's pretty smart actually. Too bad everyone uses Adblock.
I use ad block. I use facebook to see what friends are up to. If I want to buy something I will goto ebay
Never a better reason to target Facebook servers......
Hackers will pay them more attention now.
Numbers never lie, and there's never been strong conversions of people buying things directly from a Facebook feed; less than 2% conversion rate.
This "Buy Button" system *may* prove to be useful for Company pages to get people to buy time-sensitive deals they generate for potential customers that are interested enough to follow them, but not ads.
No relationship has been built with the customer and the company paying Facebook to push an ad to their face randomly; why would anyone have the intent to buy right when they receive such an (likely) impersonal buying opportunity?
Buying without recommendations from people you trust (opinion leaders or sites for enthusiasts w/ frequent reviews such as this very site) or even comparing the product to the product of others is foolish in 2014.
For Parents, hopefully their kids aren't on their facebook account because we may run into another issue when they "accidentally" press the Buy button. I sure hope there are a lot of secure steps to actually purchase the item.
