It is 9:40 on a Tuesday night. Somebody's water heater just started leaking into the garage, so they grab their phone, search for a plumber, and tap the first ad with a call button. The phone rings at your shop. Nobody is there. It rings out to voicemail, they hang up without leaving a message, and they tap the next ad down.
You paid for that click. Google charged you the same for it as it would have at 10 in the morning, when someone was sitting next to the phone. And unless you have opened one specific setting in your account, Google will do it again tomorrow night, and the night after that.
That setting is the ad schedule. In a lot of the small business accounts we look at, nobody has ever touched it. That isn't always a mistake. Plenty of businesses should run around the clock. But it should be a decision you made, not a default you never saw.
Google Ads Doesn't Know What Time You Lock the Door
Every new Google Ads campaign is set to show ads "All day." Google's own help page puts it plainly: unless you change it, your ads are eligible to appear throughout each calendar day. Google has no idea you close at 6, that your office manager leaves at 5:30, or that nobody answers the phone on Sundays. Nothing in the setup flow asks.
There is a second default hiding underneath the first. The schedule runs on your account's time zone, not your business's. If the account was set up by someone in another state, or set up years ago on whatever the setup screen picked, a schedule of 8 to 6 might actually be running 6 to 4 where your customers live. Check it before you set anything else. It is in your account settings, and it takes about ten seconds to read.
So the starting point for most owners is a campaign that runs 24 hours a day, every day, on a clock that may not match theirs. Whether that is costing you money comes down to a question Google can't answer for you.
The 9 p.m. Caller Is a Real Customer, Until Your Voicemail Sends Them to the Next Ad
The easy conclusion is "turn the ads off when you close." It is often wrong, and the people who argue for running ads around the clock have a real point.
People search when they have time to search. For a lot of households that is after dinner, after the kids are in bed, or on a Saturday morning. A homeowner researching a new roof at 9 p.m. is just as serious as one researching it at 10 a.m. Online stores should almost never switch their ads off at night, because the checkout doesn't need anyone to answer it. Booking systems are the same: if a customer can grab a 2 p.m. Thursday slot themselves at midnight, midnight is a perfectly good hour to advertise.
So the useful question is not when do people search for us. It is what happens to the person who reaches us after we have gone home. Your answer puts you in one of three groups:
- Urgent work. Plumbing leaks, locked-out cars, a tow, an emergency vet. This person needs someone now. If you don't answer, they don't wait until morning, they call the next number on the page. A click you can't answer is a customer handed to your competitor, and you paid for the handoff.
- Considered work. A kitchen remodel, a new HVAC system, a consultation with an attorney or an accountant. Nobody expects you to pick up at 10 p.m. They will happily fill out a form if you call them back promptly the next morning. Night clicks here can be some of your best, as long as someone actually makes that call.
- Self-serve sales. Online stores, ticketing, anything booked or bought without a human. Leave the ads on.
A note on voicemail, because it matters for everything below. A voicemail is a real lead. The person called you, they had a need, and they left their number. The problem is not the voicemail. It is the gap between the message and your callback. For considered work, a voicemail returned at 8:15 the next morning is fine. For urgent work, it was gone by 9:45 the night before.
The Ad Schedule Report Already Shows Which Hours Lose Money
You don't have to guess which group your night traffic falls into. Your account has been recording it the whole time.
Open a campaign, go to the Ad schedule page, and look at the three views it offers: day, hour, and day-and-hour. Set the date range to at least the last 90 days, longer if your budget is small. You are looking for two things in each time block: how much it spent, and how many conversions it produced. This is the first report we open when we manage Google Ads for a local service business, because it answers in five minutes a question owners have usually been arguing about for months.
Then open the report that tells you what actually happened on the phone. In Report editor, under ads and assets, there is a Call details report. If you use Google's forwarding numbers, it lists every call from your ads with its start time, its duration, and whether it was missed or received. Sort it by start time and compare it to your hours. If you see a cluster of calls between 6 and 9 p.m. on weekdays, that is real demand you are paying for. If a large share of them were missed, or were short calls that never turned into a booked job, you are paying for it and not collecting.
Two cautions before you act on what you find.
Don't judge an hour on a handful of dollars. A two-hour block that spent $40 with no conversions hasn't told you anything yet. A block that spent three or four times your target cost per lead with nothing to show for it has. Small accounts need a longer window to get there, which is why 90 days is the minimum, not the goal.
Be suspicious of night "conversions." If you count calls from ads as conversions, Google counts a call once it lasts longer than the minimum you set. A caller who reaches your voicemail and leaves a full message can clear that bar. That call shows up as a conversion at 9:40 p.m., and the hour looks profitable. Before you decide nights are working, check whether those calls were returned and booked. If you are not sure what your account counts as a conversion in the first place, start with why the conversion number in Google Ads can rise while sales don't.
Switching Off Nights Won't Shrink Your Bill on Its Own
Here is the part almost nobody explains, and it changes how you should think about the whole decision.
Your daily budget doesn't know about your ad schedule. If your campaign usually spends its full daily budget, and you switch off the hours from 6 p.m. to 8 a.m., Google doesn't spend less. It tries to spend the same daily budget in the hours you left on. The money that was going to night clicks moves into daytime clicks.
That can be exactly what you want. Daytime clicks are the ones you can answer, so shifting the same money into them is a good trade. But if your goal was to spend less, you also have to lower the budget. Turning off the hours alone won't do it.
The opposite case is also worth knowing. If your campaign rarely spends its full budget, because there isn't enough search volume in your area to use it up, then switching nights off really does lower your spend. There was never extra daytime demand for the money to move to.
Google changed how budgets work with ad schedules in June 2026, and it is worth being precise about what that change touched. It applies to schedules that switch a campaign off on certain days of the week: those campaigns now pace toward the full monthly amount across the days they do run. Google's documentation says the change does not affect schedules that switch off certain hours within a day. We covered the day-of-week side in detail in Google Ads Can Spend Twice Your Daily Budget. It Is Supposed To. If you close on weekends as well as at night, read that one before you change anything.
So decide what you are actually trying to do before you touch the schedule: save money, or move money to better hours. Then set the budget to match.
Smart Bidding Ignores the Discount You Set for Nights
The ad schedule page has a second control next to the on/off hours: a bid adjustment. You can tell Google to bid 30% less between 6 p.m. and 10 p.m., for example, so you still show up at night but pay less for it. It sounds like the perfect middle ground, and on the right campaign it is.
Most small business campaigns are not that campaign. If you use Smart Bidding, which includes Maximize Conversions, Target CPA, Maximize Conversion Value and Target ROAS, Google's own documentation is direct about it: your ads will strictly follow the days and times in your schedule, but manual bid adjustments won't be used. The page still lets you type in a number. It still saves it. It does nothing. Hourly bid adjustments only do their job when you set bids manually.
That isn't Google ignoring time of day. Smart Bidding already adjusts every bid using the searcher's local time and day of the week, along with dozens of other signals. If 11 p.m. clicks rarely turn into conversions, it bids less for them on its own. The catch is the same one from the last section: it is learning from whatever you told it counts as a conversion. If after-hours voicemails count, it will learn that nights are excellent and bid up for them.
So on a Smart Bidding campaign you have two real levers for nights, and a typed-in discount is neither of them:
- The schedule itself, which strictly decides whether your ad can show at all.
- What counts as a conversion, which decides what Smart Bidding thinks a good hour looks like.
If those two are right, the bidding takes care of the in-between hours. If they are wrong, no discount will fix it.
This is the same principle behind setting a bid target in Google Ads: the system does exactly what you instruct, including the mistakes.
Once You Close for the Night, Your Ad Should Ask for a Form, Not a Phone Call
For most service businesses, the best answer isn't "on" or "off." It is keeping the ad running at night but changing what it asks the customer to do.
Schedule the call button, not just the ad. A call asset is the phone number and call button that appears under your ad. Google lets you schedule it separately from the campaign, in the call asset's advanced options, so it only shows on the days and hours someone is answering. After hours, the ad still shows, but it sends people to your website instead of to a phone that rings out. Google's help page describes this exact use: scheduling the call asset to show only when your business is answering phone calls. If you still have call-only ads running, those are being retired, and what replaces the ad that only rings your phone is worth reading alongside this.
Give the night visitor a page built for night. Someone landing on your site at 10 p.m. should see a short form and a clear promise: Leave your details and we'll call you by 8:30 tomorrow morning. Not a giant "Call Now" button that connects to voicemail. The promise matters as much as the form. It tells them a real person will follow up and exactly when, which is the thing a voicemail greeting never quite says.
For more control, split day and night into two campaigns. Copy your main campaign. Give the original a schedule that matches your open hours, and the copy the opposite schedule with a smaller budget, no call asset, and a final URL pointing at that callback page. Now you can see night performance on its own line, budget it separately, and switch it off in one click if it doesn't earn its keep. The tradeoff is that each campaign gets less data to learn from, so only split if the night campaign will still see steady traffic.
Close the loop on missed calls. Many business phone systems can automatically text anyone whose call goes unanswered: Sorry we missed you, reply here and we'll get back to you first thing. It costs little, it turns some hang-ups into conversations, and it makes night clicks worth more without changing a single setting in Google Ads.
None of this works if nobody follows up. Every one of these options moves the after-hours lead to the next morning, and the next morning is where it either becomes a customer or doesn't. If that callback isn't happening reliably, fix that first. It is cheaper than any ad change. We made the Meta version of this argument in Meta Can Make Your Phone Ring. Most Service Businesses Send People to a Form., and the same logic holds on Google: the click only pays off if someone picks up the conversation.
Two Weeks of Nights Is Not Enough to Judge Your Ad Schedule
Once you have decided, setting it up takes a few minutes. A few mechanics trip people up:
- Time zone first. The schedule follows the account's time zone. If your customers are in a different one, shift the hours to match their clock, not yours.
- Fifteen-minute steps. Start and end times move in 15-minute increments. If you open at 8, starting at 7:45 catches the people searching on the way in.
- Six blocks a day, no overlaps. Google allows a maximum of six schedules per day in each campaign, and they can't overlap. Even if you run all 24 hours, splitting the day into four six-hour blocks (overnight, morning, afternoon, evening) costs you nothing and gives you a cleaner report to read later.
- Overnight needs two pieces. A schedule can't cross midnight. To run from 8 p.m. Monday to 7 a.m. Tuesday, set Monday 8 p.m. to midnight and Tuesday midnight to 7 a.m.
Then leave it alone. One quiet week of nights is not a verdict, and a schedule flipped every few days never produces a clean read on anything. Review the day-and-hour view and the call details report once a quarter, and change the schedule when the pattern is clear, not when one bad Tuesday makes you nervous. We wrote about that habit in general in Checking Your Ad Account Daily Is a Habit. It Is Not Management.
The point of all this isn't to cut hours. It is to make sure every hour your ads run, someone, or something, is ready for the customer who shows up. Sometimes that means switching nights off. More often it means keeping them on and changing what the ad asks for.
If you would rather have someone read those reports and set this up with you, it is the kind of thing we do every week, and we are happy to help. And if you would rather do it yourself, everything you need is already sitting in your account.
