Earlier quoted context omitted.
I see this a lot but I find that it can't be true on the whole for many many. We buy ads for political clients. On FB I could get a positive immediate roi for donations. Scaling huge is hard (i got one client to over $1 million last cycle for context). Admittedly but you could go a lot bigger if you look at ROI down the line with email donations. And we're not alone. I don't think the many many direct to consumer bra…
Where is the control for the experiment? What is the ROI on non-targeted ads?
For us we make a donation page. The only links that go there are from FB ads. We also use different refcodes for different ad groups AND the FB pixel passing in purchase value which is really good at optimizing FB's delivery to highest ROAS
FB is very very very good at this
I feel like people who question it or like don't understand basic attribution should do some more research before denigrating
There are other non-direct measurement, FB for instance allows you to upload offline purchases. Definitely not as clean especially if you're hitting across different channels. But a basic A/B holdout test is pretty good in that case too.
