With most advertising mediums, you can only show correlation.

But with many parts of digital, you can show certain pages of your website exclusively to those who have clicked on ads (ie. hide those pages from regular browsers).

In this way you can directly measure the direct effects of the advertising spend.

There are many businesses, including three that I own, that have grown as a sole consequence of social media advertising. We have not promoted these businesses in any other way (no SEO, no trade shows, nothing).

I'm not going to share my advertising accounts with you; I'm just going to ask you to trust that when I get my laptop out and show my results to my 'marketing skeptical' friends, they stop being skeptical.

Actual words, from one of these friends: "wow. That is like a money printing machine."

Consider for a second: how many advertisers that are actually succeeding are going to publicly call attention to their success? Would you?

The only hint is Facebook and Google's revenues. They go up, and I am one of the people who makes their revenues go up.

I'm not publishing a paper in the comments. This is HN. Regardless, you cherry picked one aspect of my comment, and it's very hard from my perspective to see that it was done in good faith.

I'd like to be proven otherwise, so, here are my key points, which you didn't contend with:

-> It's possible to completely isolate the effect of advertising spend, thereby making the effectiveness (or not) measurable.

-> I pointed to growing revenues on Google/FB's platforms, two platforms which make isolated measurement feasible.

In terms of _externally_ verifiable facts, that's the best I'll be able to give you.

The rest, you (and others) have to take on a/ good faith b/ using basic logic, that I'm telling the truth.

What about the rest of the post? Is it too much to ask you to engage constructively?

if you mean make claims with no evidence to back them up, yes I can engage more with you.
