5 automation rules every Google Ads account should have running 24/7

Google Ads' native automation rules are functional but limited — you can set simple if/then conditions, but they don't understand context, can't explain their decisions, and give you no audit trail worth reading. AdNexus AI lets you define smarter, plain-English rules that Claude interprets and acts on with your approval.

Here are the five rules we recommend setting up the moment you connect a Google Ads account.

1. The overnight budget guard

"If any campaign spends more than 120% of its daily budget before 6pm, pause it and notify me."

Budget pacing anomalies are one of the most common and expensive Google Ads problems. They usually happen because of a sudden surge in auction competition, a targeting change that broadened reach unexpectedly, or a new remarketing list that matched far more users than anticipated.

Catching this before end-of-day saves you from waking up to a campaign that burned 3x its daily budget overnight.

2. The zero-conversion kill switch

"If a campaign has spent more than $50 in the last 7 days with zero conversions and a CPC above $2, flag it for review."

This is the single highest-ROI rule you can run. Every account has campaigns that look active but are functionally dead — spending consistently, converting never. This rule surfaces them before they quietly drain another month of budget.

3. The Quality Score watcher

"If any keyword's Quality Score drops below 4, add it to a review list and suggest whether to pause, rewrite the ad, or improve the landing page."

Low Quality Scores inflate your CPCs and reduce impression share. Catching them early and getting a concrete recommendation (not just an alert) makes the fix faster.

4. The impression share floor

"If a top-performing campaign's search impression share drops below 40% for 3 consecutive days, check if the cause is budget or rank and suggest an adjustment."

Impression share drops are often invisible until you're losing significant ground to competitors. This rule keeps a floor under your best campaigns and gives you the diagnosis alongside the alert.

5. The weekly performance digest

"Every Monday morning, give me a plain-English summary of last week's performance: top 3 campaigns by ROAS, bottom 3 by CPA, any anomalies worth investigating, and one suggested action."

This replaces the Monday morning dashboard ritual. Instead of exporting data and building a summary yourself, Claude reads your account, synthesizes it, and gives you a briefing you can share with a client or stakeholder in 30 seconds.

Setting these up in AdNexus

Each of these rules can be configured in AdNexus by simply typing them into the conversation. Claude will confirm the rule, ask any clarifying questions (e.g. "Should the zero-conversion check apply to all campaigns or only non-brand?"), and schedule it to run on your chosen interval.

Every action triggered by a rule goes through the same confirmation step as manual actions — nothing executes without your approval, and everything is logged.
