His ad-tech DSP example is horrible. In reality, advertisers care about (in order of importance)

- Target audience reach (measured in millions of people)

- Cost of engagement (CPA, CPM, etc)

- Engagement metrics for verification (clicks, views, etc; so you can send bills to your clients and not worry about claims and lawyers)

The junk he listed is probably the least interesting information to an advertiser. All of it is technical details that affect your margins as an intermediary, something your clients couldn't care less about.
