His ad-tech DSP example is horrible. In reality, advertisers care about (in order of importance)<p>- Target audience reach (measured in millions of people)<p>- Cost of engagement (CPA, CPM, etc)<p>- Engagement metrics for verification (clicks, views, etc; so you can send bills to your clients and not worry about claims and lawyers)<p>The junk he listed is probably the <i>least</i> 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.
