This is one of the first questions business owners ask when they start paying attention to their Google Ads. The office closes at 5, nobody's there to answer the phone, so why would you run ads when you can't take the call? It makes intuitive sense. You're paying for clicks, and if nobody is there to convert that click into a customer, it feels like wasted money.
The problem is that the intuition is wrong for most businesses, and what we see in real accounts tells a different story. On the accounts we manage, anywhere from 30% to 50% of form submissions come in outside standard business hours. The 5pm to 9pm window is consistently one of the busiest periods for lead submissions, and the cost per lead during evening hours is almost always lower because fewer competitors are bidding. If you’re turning your ads off when the office closes, you’re going dark right when a huge chunk of your potential customers are searching and the auction is cheapest.
This post is part of our 12-point Google Ads audit. We look at ad scheduling as step 9 because it requires conversion data from earlier steps to evaluate properly. You can’t make good scheduling decisions without knowing which conversions are phone calls, which are forms, and when each type actually happens.
When People Actually Search
Think about when you personally research a service you need. You don’t do it at 10am on a Tuesday when you’re in the middle of your own workday. You do it at 8pm on a Wednesday after the kids are in bed, or on Saturday morning with a cup of coffee, or Sunday night when you’re planning the week ahead. Your customers behave the same way. The people searching for your business are often doing it outside the hours you’re open because those are the hours they have time to look.
The data backs this up consistently across industries. 30-40% of all lead form submissions across service businesses come outside the 9-to-5 window. Friday evening through Sunday accounts for 25-30% of total weekly lead volume for consumer services. Saturday generates roughly the same lead volume as a weekday, and Sunday is only slightly behind. These aren’t people casually browsing. They’re people with a problem who are actively looking for someone to solve it.
An accounting firm we work with was turning ads off every evening and all weekend. They assumed nobody would be searching for a CPA at 9pm on a Thursday. When we turned the campaigns on 24/7 for a 30-day test, evening and weekend form submissions accounted for 41% of their total leads that month, and the cost per lead during those hours was 28% lower than during business hours because fewer competing firms were bidding.
Almost half their leads were coming from hours they had been dark for over a year.
Calls vs. Forms: The Distinction That Changes Everything
The reason ad scheduling gets so much wrong advice is that people treat all conversions the same. They’re not. A phone call at 8pm to an office that closed at 5 is a different situation than a form submission at 8pm that sits in an inbox until morning. The conversion type determines whether after-hours ads make sense, and most businesses have both types running simultaneously without thinking about how that affects their scheduling decisions.
Phone calls need someone to answer them. That’s not negotiable. If your primary conversion action is phone calls and nobody picks up after 5pm, those after-hours clicks are generating voicemails that may or may not get returned the next morning. The data on callback rates is not encouraging for most businesses. But even here, the answer isn’t necessarily to turn ads off. It might be to set up a simple after-hours answering service, or to make sure the form on your landing page is prominent enough that people who can’t get someone on the phone still have a way to reach you.
Form submissions, scheduling widgets, and online booking tools work 24 hours a day. Someone filling out a contact form at 10pm doesn’t need you to be at your desk. They need a confirmation that their form went through and a response by the next morning. If your website has a functional form or scheduling tool, there is essentially no reason to turn ads off outside business hours. The form captures the lead, your team follows up in the morning, and you paid less per click to get that lead because the auction was less competitive at 10pm than it was at 2pm.
The approach we recommend on most service business accounts is to start ads one hour before the office opens (to capture early-morning searchers who are planning their day) and run them continuously through the evening. If the account generates enough data, we break conversions out by type and hour to see exactly when phone calls happen versus form submissions. On accounts where 80% of evening conversions are forms, running ads 24/7 is almost always the right call. On accounts where 80% of conversions are phone calls with no after-hours answering, the decision is more nuanced, but even then we usually keep ads running in the evening with a strong form CTA on the landing page.
Why Your Competitors Being Off Is Your Advantage
Google Ads is an auction. Every time someone searches, the advertisers who are running ads at that moment compete for the available slots. The more advertisers competing, the higher the cost per click. During business hours, when every competitor in your market has their ads turned on, you’re in the most crowded and most expensive auction of the day. At 7pm, when half of them have turned their ads off for the evening, you’re competing against fewer advertisers for the same searcher.
This is why evening and weekend CPCs are consistently lower for service businesses. It’s basic auction economics. Fewer bidders means lower prices. The searcher at 7pm has the same intent and the same need as the searcher at 2pm, but you’re paying less to reach them because your competitors decided that 5pm was quitting time for their ads too.
Smart Bidding Already Handles Time of Day
If your campaigns are running on a Smart Bidding strategy (Maximize Conversions, Target CPA, Target ROAS, or Maximize Conversion Value), there’s an important technical point that most business owners and a surprising number of agencies don’t know. Smart Bidding already factors time of day into every bid it places. It knows from historical data which hours are more likely to produce conversions and adjusts bids automatically. It will bid higher during high-conversion hours and lower during low-conversion hours without anyone telling it to.
This also means that manual bid adjustments on your ad schedule don’t do anything on Smart Bidding campaigns. If your agency set up a schedule that says "bid 20% higher from 9am to 12pm" and the campaign is running Max Conversions, Google ignores that adjustment entirely. The algorithm makes its own real-time bidding decisions based on signals that include time of day, day of week, device, location, and dozens of other contextual factors. Layering manual schedule adjustments on top of that is redundant at best and confusing at worst.
The only scheduling action that still works on Smart Bidding is turning ads on or off. You can tell Google "don’t show ads between midnight and 6am" and it will respect that. But percentage-based bid adjustments on the schedule are ignored. So if your agency is charging you to "optimize your ad schedule" on a Max Conversions campaign by adjusting bids by hour, they’re making changes that have zero effect. The algorithm was already handling it.
The Speed-to-Lead Problem
Running ads after hours solves the visibility problem, but it creates a follow-up problem that you need to plan for. Research consistently shows that the speed of your response to a lead has a massive impact on whether that lead converts to a customer. Contacting a lead within 5 minutes makes you 21 times more likely to convert them compared to waiting 30 minutes. After an hour, the odds drop dramatically. After 24 hours, you might as well not bother.
If your ads run until 10pm and a form comes in at 9:47pm, that lead sits in your inbox for 11 hours before anyone sees it. By the time you respond at 9am, that person has already submitted forms to two other businesses who responded faster, or they’ve moved on entirely. Without after-hours lead response, those leads sit for 10-12 hours before anyone sees them. By then, the prospect has already submitted forms to two other businesses or moved on entirely.
This doesn’t mean you shouldn’t run after-hours ads. It means you need a plan for handling after-hours leads. An automated email or text confirmation that says "Got it, we’ll call you first thing tomorrow morning" buys you time. A simple answering service that takes messages and sends them to your phone costs a fraction of what you’re spending on the ads that generated the lead. Some businesses set up automated scheduling tools that let the customer book an appointment directly without waiting for a callback. The lead comes in at 9pm, they book a 10am consultation, and your team walks in the next morning with an appointment already on the calendar.
The worst approach is running after-hours ads with no follow-up system and letting leads pile up until someone checks the inbox at 9am. That’s paying for leads you’re almost certainly going to lose.
When You Actually Should Turn Ads Off
There are situations where pausing ads during certain hours makes sense, but they’re more specific than "the office is closed."
If your conversion data clearly shows that a particular time window generates clicks with zero conversions over a 90-day period, and the sample size is large enough to be meaningful (not 5 clicks on a Saturday, but 50+ clicks over three months with nothing to show for it), then pausing during that window is reasonable. This is a data-driven decision, not an assumption.
If your business truly cannot handle after-hours leads in any form, and I mean no form on the website, no scheduling tool, no answering service, no automated confirmation, and every conversion requires a live human conversation to move forward, then running ads when nobody can have that conversation is genuinely wasteful. But this situation is rarer than people think. Most businesses can put a form on a landing page.
If you’re on a very tight budget and need to concentrate spend into the hours with the highest conversion rate, narrowing your schedule can make sense as a budget allocation strategy. But check the data first. The hours you think are highest-converting might not be, and removing evening hours might cut your lowest-cost leads rather than your lowest-quality ones.
How to Check Yours
Go to your Google Ads account. Pull up the campaign you want to evaluate, then segment the data by hour of day and day of week. You’re looking for three things: when your clicks happen, when your conversions happen, and what those conversions cost by time window.
If you can, break conversions out by type. Most accounts have phone calls and form submissions tracked as separate conversion actions. Look at when each type fires. You might find that phone call conversions cluster between 8am and 6pm (when someone answers), but form submissions happen steadily through 10pm. That tells you the ads should keep running in the evening, even if the phones are off, because the forms are still converting.
Check at least 90 days of data. Anything less and you’re looking at noise, not patterns. If the account only generates 5 conversions a month, there isn’t enough data to make meaningful scheduling decisions at all, and you should leave the schedule open and let Smart Bidding handle the time-of-day optimization on its own.
Also check what your competitors are doing. If you see a spike in impression share during evening hours (meaning your ads are showing more often because competitors dropped out), that’s confirmation that you’re getting cheaper access to the same audience. You can find this by segmenting impression share data by hour, though Google makes this harder to see than it should be.
Why This Matters
Ad scheduling sounds like a minor optimization, but it controls when your ads are eligible to show, which directly affects how much of the available demand you’re capturing. A business that turns off ads at 5pm and back on at 8am is invisible for 15 hours a day, including the hours when the majority of their potential customers are searching. Over the course of a month, that’s a lot of leads handed to whoever stayed on.
If your agency set your schedule to business hours when the account was launched and never revisited it, that’s worth a conversation. Pull the hour-of-day data together and look at what’s actually happening. The answer might be that your current schedule is fine. But it might also be that you’ve been leaving your best leads on the table every evening for the last year, and the fix is as simple as leaving the ads on and putting a form on the landing page.
