Most performance marketers monitor Google Ads the same way: log in, scan the numbers, hope nothing broke overnight, close the tab. It works right up until the day it does not. A budget runs away on a Saturday. A top campaign's cost per conversion doubles on a Tuesday and nobody notices until Thursday. By the time you spot it, you have already paid for the mistake.
The fix is not to check more often. Checking more often just trades your attention for peace of mind, and your attention is the whole point. The fix is to make the account watch itself. Google Ads automated rules do exactly that. They are the simplest way to catch problems early without living inside the platform. In over a decade of managing paid campaigns, a small set of well-built rules has saved me more wasted spend than any dashboard ever did. Here is how to set them up.
What Google Ads automated rules actually are
A Google Ads automated rule is a condition plus an action, run on a schedule. You define the condition ("cost today is greater than 200"), the action ("email me" or "pause the campaign"), and how often the rule runs. When the condition is true, the action fires. That is the whole model. No code, no external tools, all configured inside the Google Ads interface under Tools, then Rules.
The important shift is philosophical, not technical. Instead of you asking the account "is everything okay?" ten times a day, the account tells you the moment something is not. Your default state becomes silence, and silence means on track. You only spend attention when there is a real reason to. For a deeper look at the numbers behind proactive checks, our guide on how to track ad spend covers the metrics worth watching.
Rules versus scripts
Automated rules are the no-code option. If you have heard of Google Ads scripts, those are JavaScript programs that do far more complex logic but require coding. For monitoring and guardrails, rules cover almost everything without a developer. Reach for scripts only when a rule genuinely cannot express what you need.
Five automated rules every account should have
You do not need dozens of rules. You need a few that cover the ways an account quietly loses money. Start every rule as email-only so you can watch what it catches before you let it take action. Here are the five I set up first on any account.
1. The overspend guardrail
Email me when a campaign's cost today is more than a set threshold, for example 150 percent of its average daily budget. This catches runaway spend from a bidding change, a broad match term gone wrong, or a tracking break the same day it happens instead of at month end.
2. The performance drop alert
Email me when a campaign's cost per conversion over the last 7 days is above my target. This is your early warning for a campaign that has slipped, before the damage compounds across a full month of spend.
3. The zero-conversion spend alert
Email me when an ad group has spent more than a set amount in the last 3 days with zero conversions. Money going out with nothing coming back is the clearest signal that something needs a human look, whether it is intent, tracking, or a landing page.
4. The budget pacing check
Email me a weekly summary of spend by campaign so you can see whether you are on pace for the month. Pacing problems are boring and expensive. A weekly nudge keeps them from becoming an end-of-month surprise. Our guide on ad budget pacing goes deeper on this.
5. The low-impression or disapproval alert
Email me when a campaign that should be spending drops to near-zero impressions. This surfaces disapproved ads, an exhausted budget, or a paused campaign nobody meant to pause. A campaign serving nothing is invisible in a normal spend review, which is exactly why it needs its own rule.
A note on automatic actions
Rules can pause campaigns and keywords on their own. That is tempting, but a rule acting on delayed or incomplete data can pause something it should not. Run every rule as email-only for a few weeks first. Once you trust what it flags, promote the safest ones, like the overspend guardrail, to automatic actions. Keep judgment calls in human hands.
How to set up an automated rule, step by step
Setting up the overspend guardrail takes about two minutes. The same flow works for any rule. Here is the path inside Google Ads.
Open the Rules panel
In Google Ads, go to Tools, then under Bulk actions choose Rules. Click the plus button to create a new rule.
Pick what the rule applies to
Choose the type, for example a campaign rule, then select the campaigns it should watch. You can apply it to all enabled campaigns or a specific set.
Set the action and condition
Choose "Send email" as the action. Add the condition: Cost greater than your threshold, over the time range Today. This is your overspend guardrail.
Choose the frequency
Set the rule to run Daily at an hour that suits you, or more than once a day for fast-moving spend risks. Remember that Google evaluates the rule on data available at that moment, which can lag by a few hours.
Preview, name, and save
Use Preview to see what the rule would catch with current data, give it a clear name like "Overspend guardrail 150 percent", and save. Repeat for the other four rules.
Google's own documentation on automated rules lists every available condition and action if you want to build something more specific. Once your five rules are live, add them to a broader review habit. Our Google Ads optimization checklist covers the deeper work that rules cannot do for you.
Where automated rules fall short
Rules are a strong first layer, not a complete system. Being honest about the gaps helps you decide what to build on top.
- infoThey live inside one account. Rules are set per account. If you manage ten accounts, you rebuild every rule ten times and watch ten inboxes. There is no single roll-up of what fired across everything you manage.
- infoThey only see Google. A rule cannot tell you your Meta budget is pacing hot or your LinkedIn cost per lead spiked. Cross-channel blind spots stay blind.
- infoAlert fatigue is real. Too many rules, or thresholds set too tight, and the emails become noise you learn to ignore. Fewer, sharper rules beat a flood of them.
- infoData can lag. Rules act on the data available when they run, which is not always real time. For most guardrails this is fine, but do not treat a rule as a millisecond-precise circuit breaker.
Building a calmer monitoring system
The goal of all of this is not more alerts. It is fewer moments where you have to wonder whether the account is okay. Automated rules get you most of the way there for a single Google Ads account. Set the five rules above, run them email-only until you trust them, and your daily check shrinks to a glance.
If you run paid media across several accounts and channels, the account-by-account gaps start to add up. That is the problem aubado is built to solve. It sits on top of your channels and watches spend and performance across all of them, so a single daily check tells you what actually needs attention, no matter which account or platform it lives in. Rules inside Google Ads are the right first move. A tool like aubado picks up where they stop, so you can check once a day, stay in control, then close the tab and do your real work.
- checkStart with five rules. Overspend, performance drop, zero-conversion spend, pacing, and near-zero impressions.
- checkEmail first, act later. Watch what each rule catches before you let it pause anything.
- checkKeep it sparse. A few sharp rules beat a wall of alerts you learn to ignore.
- checkAdd a cross-account layer once one account's rules are no longer enough to see the whole picture.
