Facebook has better interest based targeting than anyone else on the web. Google is the king of intent based targeting.

Source: I've managed and tested $10 million+ of ad spend that needed provable ROI across a wide variety of platforms.

I'm curious about your experience here. In my experience Digital folks come with a lot of smoke and mirrors that crumble under standard statistical analysis.

I mean, you don't need too many stat techniques for basic tracking:

1) Set up Facebook pixel on your checkout thank you page + collect referral into into a database.

2) Spend $1,000

3) See how many purchases Facebook reports came from Facebook, check out how many sales you get recently have the Facebook referrer.

4) Repeat if sales revenue > $1,000.

This is obviously the simplest use case possible, but there you are. It's pretty reliable.

This is missing some testing. In multichannel environments you have the potential for multiple touches, as well as baseline if your company is large enough. For example, a traditional product like cars: you have a baseline of folks who come in, and then you have (ideally addtional/higher rate of) folks that come through the digital channel, such as engaging an online salesperson. Do the digital channels generate a higher rate of purchase than the baseline channel? If so, is the lift statistically significant? These are what I mean. Revenue moving through a digital pipeline could be because people happened to fall into that bucket but were already going to purchase anyway. In other words, some of the $1000 went to non-incremental marketing. The goal is to make sure the incremental marketing exceeds the spend.

I guess for (4) you mean, "repeat if [attributable] _profit_ increase [vs control] > $1,000"?

Not much point in driving $1,000 in _revenue_ with $1,000 in marketing spend unless your margins are 100%.

Thanks sib. That's exactly the point I was trying to drive home.

yes

Honestly in my experience they don't. The low quality ads is a major reason I have ramped down my Facebook usage. Google is sort of ok. The targeting on every platform is still 1999 quality. There literally has been zero change to the end user despite all the data collection. At the end of the day, it's low quality advertising.

Not if you are on Facebook or Amazon.

Most Facebook use is mobile and the Facebook app is one of the most popular.

Ad blocking works on Google’s website.
