Lesson notes

Four beats twelve. In Ad Manager, the lower number wins.

Priority is the number that decides which line items get first claim on an impression.

Here’s the ladder for one homepage slot on news.example. Priority four is Sponsorship, a guaranteed booking for a share of impressions, like a one day takeover. Six, eight or ten is Standard, guaranteed campaigns with an impression goal. Twelve is where price decides. Price Priority, Network and Bulk line items compete there with AdX and AdSense. Sixteen is House, your own promos, which serve only when nothing else will. So during Monday’s takeover, priority twelve demand barely sees that slot. One twist, AdX can still challenge guaranteed line items. That’s episode six.
