I am surprised a lot of people are saying its more expensive than facebook ads. After running ads on both platforms for 3 years, I get MUCH better cost per acquisition on google/YouTube than facebook. I advertise primarily on YouTube and Its honestly amazing the amount of video views, CTR and conversions I can get vs what I pay and comparing it to facebook ads, I've barley been putting my ad budget into facebook ads the last 7-8 months because I get so much better results using google/YouTube vs facebook In terms of pricing and conversion rates.
