As above Facebook Ads is pretty much a joke for B2B - even if someone is the decision maker of a business you want to target, if they're on Facebook, they're not really there to buy.
I don't think the intent is there.
I've been testing Bing Ads because Google Ads is just getting ridiculous in terms of the CPC.
Don't get me wrong, the traffic from Bing Ads is incredibly low vs Google Adwords but then again so is the cost.
I have a particular ad which seems to hit the spot when it comes to CTR and also conversions.
Out of 40 clicks this week, 17 went through and made an enquiry - 7 of them seemed like no-goers.
Sent out 10 proposals in total, anywhere from £15k to £35k each - for this to be a "success" only 1 needs to accept - because I've spent pennies on CPC.
I know everyone only talks about Google, but there are businesses and people searching for stuff on Bing as well.
In the B2B space, I'd rather show an ad to someone searching for what I offer vs just showing an ad to someone based on what I think they might be looking for.
