Notes from inside the accounts.
We spend our days in ad accounts, tag containers, and analytics properties. This is where the patterns get written down, by the seniors doing the work rather than a content team. Same rules as everything else on this site: evidence first, numbers attributed, no recycled guru advice. If a note can't show its math, it doesn't get published.
