Google recently announced a change to how budget pacing works for campaigns that use ad schedules; specifically, those that are turned off on certain days of the week. On the surface, Google positions this change as an improvement for advertisers, but if you have any campaigns structured around deliberate day-parting, this change requires your attention before June 1st.
Right now, if your campaign runs on an ad schedule that limits to certain days (such as Monday through Friday only) Google will roughly spend your daily budget multiplied by the number of active days in the month. Depending on your day parting schedule that could be wildly different from 4 days a month up to 30 days.
Starting June 1, Google will pace all campaigns toward the full monthly cap, 30.4 times your daily budget, regardless of how many days your ad schedule actually runs. Although your ads still won't show on disabled days, the system will now try to spend more on the days they do run. This will push spending higher on active days to compensate for the idle ones.
Simply put: the same daily budget will go further per active day than it used to if you are not running your ads everyday of the month.
Say you're running a campaign with a $100/day budget, scheduled Monday–Friday only.
In a 30-day month with 22 weekdays:
That's an $840 difference billed across the same 22 active days. Your cost per active day will increase meaningfully even if you haven't touched a single setting, or paid attention to your spend throughout the month.
Note: Your billing protections remain intact. Google will never charge more than 2× your daily budget on any single day or more than 30.4× your daily budget in a month. The change is in pacing behavior and how aggressively the system tries to reach those limits.
This change is largely invisible if your campaigns run 7 days a week. The impact is concentrated on campaigns where ad scheduling is doing real work:
Google's framing is that this change helps you "hit your monthly spending goals." The honest reality is that it assumes your monthly goal is always the maximum allowed spend, and that's isn’t true for everyone’s set up.
Many advertisers use ad schedules precisely because their target audience isn't available or converting on certain days, and the budget is finite. If you've been getting predictable, comfortable daily spend based on active-day pacing, you may see a noticeable jump in monthly charges starting June without any intentional change to your settings.
Additionally, if your campaigns are conversion-target driven (Target CPA or Target ROAS), the system has more flexibility to bid aggressively on active days, which could push CPCs higher during the hours and days you do run, even if total conversion volume doesn't scale proportionally.
Here's a straightforward action plan based on your situation:
Pull a list of all campaigns using ad schedules that disable entire days. If you're a Two Trees client, we'll flag this proactively during our next review cycle. If you manage your own account, go to Campaigns → Ad Schedules and look for any campaign not running all 7 days.
For each affected campaign, multiply your current daily budget × 30.4. If that number is higher than what you've been spending or budgeted to spend monthly, action is needed.
If you want to maintain approximately the same monthly spend as before, reduce your daily budget. The formula is straightforward:
New daily budget = (Current daily budget × Active days per month) ÷ 30.4
Example: $100/day × 22 active days ÷ 30.4 = $72/day new budget to maintain ~$2,200/month spend.
If conversion data supports running on the disabled days, this change is actually an opportunity to reconsider those restrictions and let the algorithm work with a fuller dataset. If the schedule is there for a good reason such as service hours, staffing, industry demand patterns, keep it, and adjust the budget instead.
There's a secondary concern that deserves its own callout and Google's announcement does not mention it.
Google has always had the ability to spend up to 2× your daily budget on a single high-performing day. That mechanic is unchanged. What is changing is the pressure the pacing system is under, and that matters
Under the old system, a campaign running 22 days a month was pacing toward ~$2,200. The algorithm had modest incentive to push hard on any given day. Under the new system, that same campaign is pacing toward $3,040, delivered across those same 22 days. That's a meaningfully higher target to close, with the same number of opportunities to spend. When the system sees strong conversion signals early in the month, it now has both the incentive and the mechanism to bid more aggressively: potentially burning $200 on a day that previously would have seen $100.
For campaigns with compressed active schedules (such as three days per week) this pressure is amplified further. The algorithm is trying to hit a 30.4-day target across 12–13 actual days. A strong Monday could accelerate spending before you've had a chance to review the week's performance.
Set up budget alerts in Google Ads before June 1. This is a simple, low-effort safeguard that gives you early warning if spend accelerates faster than expected. To set one up: navigate to your Campaign, click Budget and then enable alert thresholds at a percentage you're comfortable with (we recommend 75% and 90% of your monthly target).
For the first 4–6 weeks after the change goes live, we'd also recommend checking daily spend reports more frequently than usual, particularly if you have a compressed schedule and an automated bidding strategy. A strong early-week performance signal could accelerate spend faster than you've been accustomed to, and catching it early gives you time to adjust before it compounds.
We're conducting a full audit of all client accounts ahead of the June 1 deadline. Any campaigns with day-based ad schedules will be flagged, and we'll reach out with specific recommendations before the change takes effect. We won't make unilateral budget adjustments without client sign-off, but we'll make sure you have the information to make the right call.
If you have questions about your specific account or want to get ahead of this now, reach out to your account manager directly. You can also read more about the pacing update from Google themselves.
