My experience is that Facebook wants you to spend some money with them. Depending on the type of business, having a Page is a wise tactic. For bang from it, though, you need to use Boost Post or other types of FB promotions.
I’ve just put up a Facebook ad for a video post – I’m billed in GBP but this seems to get charged at around 1 cent per view.
Views have to be at least 3 seconds to trigger a charge which is slightly shorter than a YouTube ad but a lot cheaper and with a lot more targeting options. With my “massive” budget of £1 a day it’s getting a few likes and a few clicks through to an affiliate link but no sales yet (one sale every 2 – 3 weeks would break even)
Yes, it’s not a particularly long view (but probably longer than I see TV adverts on fast forward) and my thoughts were that it’s because it keeps people on Facebook longer plus they’ve got a lot of “inventory” available.
