Rules

A rule watches this ad account's own figures and either tells you what it found or acts inside what you allow.

Rules, under the ⋯ on the Campaigns bar, opens them: what runs, what each one watches, and every night it has checked.

When a rule runs

Every night, after the figures for the previous day come in.

The tape Nomi keeps is daily, so a rule reads whole days. There is no hourly check: an hour of a campaign is mostly noise, and a rule that fired on it would pause things that were fine by morning.

A rule runs no model. It costs no credits, however many objects it reads.

Writing one

Start from one of the three, or press New rule. Before you save it, See what it matches reads today's figures and lists the objects it would have found, with the arithmetic beside each. A rule that matches nothing today is not broken; it says so and is still checked every night.

What a rule is made of

What it watches: campaigns, ad sets or ads.

When: a figure, above or below a value, over the last day, 3, 7 or 14 days. The figures are cost per purchase, return on spend, spend, purchases, click rate, frequency and cost per 1,000 views.

A minimum spend, under which it says nothing. Below that one purchase either way decides the answer, which is not a finding.

Two conditions at most, and both have to be true.

Then: tell you, pause it, or cut its budget.

Suggest or act

A rule that suggests writes you a notification. Opening it takes you to that object on Campaigns and opens its detail, with the rule's name, the arithmetic behind the match and two answers beside the object's own controls: do what the rule wants, or dismiss it.

A rule that acts does it that night and tells you afterwards. It may only pause something or lower a budget; no rule raises a budget on its own. It acts at most three times a night for the whole brand, never switches off more than about a fifth of what the account spent over the last week in one night, and every change still goes through the same permission and the same daily ceiling your own press does. Anything past those limits waits for you as a finding.

Writing a rule that acts needs a brand admin. Anyone who can work in the brand can write one that suggests.

Dismissing

Dismissing one quiets that rule about that object for a week.

An answer nobody gives expires after two days, because the figures behind it have moved on by then.

Where to see what happened

Every night's run is listed, including the nights nothing matched. A list that only shows findings cannot tell a quiet night from a rule that never ran.

Each change a rule made is in the same log as the changes you make by hand, marked as the rule's.
