Automated rules are instructions you set in Google Ads that make a change on a schedule when certain conditions are met. A rule might pause an ad group every Friday evening, raise a budget on the first day of a sale, or email you when a campaign’s cost per conversion climbs above a figure you choose.
How automated rules work
Each rule has four parts. First, what it acts on: campaigns, ad groups, ads, keywords or budgets. Second, the action, such as pause, enable, change a budget, change a bid or send an email. Third, the conditions, which can be based on settings or performance over a date range you pick, for example “cost over £200 in the last 7 days with zero conversions”. Fourth, the frequency: once, daily, weekly or monthly, at a set time.
At the time of writing (October 2026), rules sit under the bulk actions area of the Tools menu. Each run is logged, so you can see what the rule changed and undo it. Rules work alongside change history, which records the edits a rule makes in the same way as manual ones.
Rules are simple by design. Anything that needs calculations across campaigns, external data or more complex logic is better handled by Google Ads scripts.
Why it matters
Rules take routine housekeeping off your plate and protect you while you are not looking. A restaurant group might enable promotions for a bank holiday weekend and pause them again on the Tuesday without anyone logging in. A small business owner can ask for an email whenever a campaign spends a set amount without a single enquiry, rather than discovering the problem at month end.
They also carry risk. A rule runs whether or not the situation is what you imagined when you wrote it. A rule that pauses keywords with no conversions in 14 days will pause good keywords during a quiet fortnight, or during a tracking fault. Rules that change bids also sit badly with Smart Bidding, which sets its own bid at every auction, so a bid rule on those campaigns either does nothing or works against the strategy.
Common mistakes
- Writing conditions on too little data, so normal week-to-week variation triggers changes.
- Using rules to change bids on campaigns that run on Smart Bidding.
- Two rules acting on the same item in opposite directions, so one undoes the other.
- Forgetting a one-off rule exists, so a seasonal budget increase repeats the following year.
- Pausing items on zero conversions without checking first that conversion tracking was working.
How to act on it
Begin with rules that alert rather than act. An email when cost passes a threshold without conversions, or when a campaign stops spending altogether, gives you the information without the risk of an automatic mistake. Once you trust the conditions, let well-tested rules take actions such as scheduled pauses for sale periods.
Give every rule a clear name that says what it does and why, so anyone else working in the account understands it. Review the list of active rules every quarter and delete any that no longer apply. If you want a second opinion on what your account should automate and what it should leave to a person, that is part of how I run monthly PPC management. Bid decisions themselves are usually better left to automated bidding strategies than to rules.
