1. Work on keyword research. Long tail keywords. Negative keywords. If you only rely on keywords Google recommends, you're missing out on quite a bit.
2. Creating ad groups. You can't create an ad group with a 100 keywords in it. They have to be narrowly focused and shouldn't have more than a handful of keywords in each of them.
3. Focus on landing page quality. Create headlines dynamically based on the keywords.
4. Track ROI. And pause the ad groups and ads that result in negative ROI.
And this is only for the search network. Not the display network.
Compared to this, Facebook is pretty simple. But yes - Facebook needs to do a better job educating folks how to best use their ad platform.
Yellow page ad strategies work for Google because people already have buying intent when they run a search. Radio ad strategies work for Facebook. Its more suitable for brand building. If you are selling cars, and an average person buys a new car every 7 years - you won't see a lot of sales in the first 3-6 months. Facebook needs to educate on this.
