Why Google's 2x daily budget rule wrecks month-end
Google can spend up to twice your average daily budget on any single day. It promises only that a full calendar month will not exceed your daily budget times 30.4, so a campaign can post a run of double days during high-demand periods and quietly consume the month's money by the third week. The result is a dead final stretch, exactly when conversion rates are often at their best.
PPC Tuner tracks run-rate against your monthly plan throughout the day and stages intraday budget adjustments in the AI Action Center before depletion happens. Each change arrives as an exact Google Ads mutation with the pacing math attached, and it only publishes when you approve it. Campaigns are never paused or deleted to correct pacing, so Smart Bidding keeps its auction history.
Overpacing
Budget reductions and modest target tightening are staged on the campaigns burning fastest, rather than a blanket cut.
Underpacing
Freed budget is routed to campaigns already clearing target CPA or ROAS, using shared budget groups where they exist.
Guardrails
Target shifts are capped near 20% per cycle so Smart Bidding does not re-enter learning mid-month.

Google can spend up to 2x your average daily budget on any single day, so a $200 daily budget can post a $400 day. Over a calendar month Google will not bill you more than your average daily budget times 30.4, but within the month the spend curve can be extremely uneven, which is how accounts deplete their monthly budget in the third week.
