Google Ads Ad Scheduling for Small Businesses

What an ad schedule does

Everything below comes from Google Ads Help, starting with About ad scheduling. If you are new to Google Ads, start with our Google Ads basics guide; this page covers only the schedule settings.

By default a campaign is set to show ads "All day", which means ads can appear at any time of every day. An ad schedule changes that in two ways. You can choose the days of the week and the hours when ads may show, and you can set bid adjustments to raise or lower bids for particular days and times.

A schedule only limits when ads are allowed to show. It does not create searches. As Google puts it, "if no one searches for your keywords at the specified time or day you scheduled, your ads are not going to show."

Two limits to know before you start. Ad scheduling does not work with App campaigns. And you can create at most 6 ad schedules per day for each campaign, so a day can be split into a few time blocks but not dozens.

Setting up a schedule

Google's Set up an ad schedule page gives the steps:

1. In Google Ads, open the Campaigns menu and go to Ad schedule.
2. Select the pencil icon, then choose the campaign.
3. Pick the days and times when ads may show.
4. Select Save.

Once a schedule exists, it works as an allow list: "Your ad won't show during the dates and times that aren't listed on your ad schedule." If you add Monday to Friday, 8 AM to 6 PM, the campaign is off all weekend and every evening. Check that every period you want is on the list.

A schedule cannot cross midnight in one entry. To run ads from Monday 11 PM to Tuesday 7 AM, Google says to create two entries: Monday from 11 PM to 12 AM, and Tuesday from 12 AM to 7 AM.

To change a schedule later, go back to the same page, select the pencil icon, and remove a period with the "x", edit the times, or select Add for a new one.

Your account time zone

Schedules run on the time zone of your Google Ads account, not your customer's. Google's advice is to "adjust your ad schedule to account for any difference in your target customers' time zone." If your account is set to Pacific time and you advertise to customers in New York, a schedule of 9 AM to 5 PM in the account is 12 PM to 8 PM for them.

Check the time zone before you build a schedule. According to Google's time zone and currency settings page, "Your time zone is permanently set when you set up your account." It cannot be changed afterwards. To use a different time zone you have to create a new account. The same page notes that reports split by time also use the account time zone, and that the time zone does not affect where your ads show.

Bid adjustments by day and hour

Bid adjustments let you bid more at hours that bring more business and less at hours that do not, without switching ads off. Google's About bid adjustments page gives a range of -90% to +900% for ad scheduling adjustments, set at campaign level. You need a custom ad schedule first, then the adjustment is set on the Ad schedule page.

To set one, Google's Set up an ad schedule bid adjustment page says to open Ad schedule from the Audiences, keywords, and content menu, select the pencil icon next to the value in the "Bid adj." column, choose Increase or Decrease, enter a percentage and save.

A few rules from the same pages:

• An adjustment changes what you pay per click at that time, but "your average daily budget won't change."
• When the scheduled period is over, normal bids come back, unless other adjustments such as location or device apply.
• Adjustments combine by multiplying. Google's example: a $1.00 bid with +10% for Tuesday morning is $1.10, and an extra +20% for Anchorage makes it $1.32.
• Combined adjustments cannot raise a bid by more than 900%.

Location adjustments work the same way; our location targeting guide covers the places side.

Ad schedules and Smart Bidding

Many campaigns now use automated bidding. For these, the schedule and the bid adjustment behave differently, and Google is clear about it. Smart Bidding strategies, which Google lists as Target CPA, Target ROAS, Maximize conversions and Maximize conversion value, "don't use your manual bid adjustments (for example, +20% on Saturdays), they do respect your Ad Schedule settings."

So with Smart Bidding:

• The days and hours in your schedule still decide when ads may show. Google says "Your ads will strictly follow the days and times you have set in your Ad Schedule."
• A +20% for Saturday or -50% at night is ignored. Google says Smart Bidding "automatically optimizes bids based on performance data depending on the time of day".

The bid adjustment setup page says ad schedule bid adjustments are available for campaigns using the Maximize clicks automated strategy. If you are choosing a bid strategy, our Google Ads budgets and bidding guide explains the options.

How schedules affect your budget

Google changed how daily budgets work with ad schedules on June 1, 2026, as explained in Changes to Google Ads budget pacing for Ad Scheduling. The change applies to schedules that switch a campaign off on whole days of the week, not to schedules that only switch off some hours within a day.

The limits themselves did not change: you are not charged more than twice your average daily budget on any day, or more than 30.4 times it in a month. What changed is pacing. Google now tries to spend up to the 30.4 monthly limit even when the campaign runs on fewer days. Ads still never run on days your schedule turns off.

Google's own example: a campaign with a $100 daily budget that runs 20 days a month used to pace towards $2,000, and now paces towards $3,040. To spend about $2,000, Google suggests a daily budget of about $66. For campaigns that run 15 days a month or less, Google says the maximum is the daily budget times 2 times the number of active days.

If you run a weekday-only campaign, check your daily budget against what you want to spend in the month.

Call assets and business hours

If your ads ask people to phone you, the times matter twice: a call nobody answers is a lost lead you still paid for. Google's About call assets page says "You can set numbers to appear only when your business can accept calls."

This is a separate setting from the campaign schedule. In About assets, Google explains that for supported assets you can set an asset schedule, "For example, you can schedule call assets so they only show during the hours your business is able to take calls." So a campaign can run all day while the phone number appears only during office hours. To see which calls came from which ads, read our call tracking guide.

Reading the day and hour reports

Before you cut hours, look at the data. On the Ad schedule page, Google shows a chart of when your campaign's ads showed. It shows clicks by default; you can switch it to impressions, CTR, average CPC or cost, and use the "Day and Hour", "Day" or "Hour" subtabs.

These reports use the account time zone, so read the hours in that time zone. Look at conversions where you track them, not only clicks: an hour with many cheap clicks and no enquiries is a better candidate for a lower bid than an hour with few clicks that turn into calls.

A checklist for a small business

1. Check the account time zone and how it differs from where your customers are.
2. Run the campaign on "All day" first unless you have a clear reason not to, so you get day and hour data.
3. Look at the Day and Hour report, with conversions, before changing anything.
4. Turn off hours only when you cannot serve the customer then, for example when calls go unanswered.
5. On manual bidding or Maximize clicks, use bid adjustments for weaker hours instead of switching them off. On Smart Bidding, rely on the schedule only.
6. If you turn off whole days, review the daily budget under the June 2026 pacing rules.
7. Schedule call assets to your phone hours.

Frequently asked questions

Do Google Ads run all day by default?

Yes. Google says campaigns are set to show ads "All day" by default, so ads are eligible to appear throughout each calendar day until you add an ad schedule.

Which time zone does the ad schedule use?

Your Google Ads account's time zone. Google says this is set permanently when the account is created and cannot be changed, so adjust the schedule for customers in other time zones.

Do ad schedule bid adjustments work with Smart Bidding?

No. Google says Smart Bidding strategies such as Target CPA and Maximize conversions don't use manual bid adjustments, but they do respect the days and times in your ad schedule.

How many ad schedules can a campaign have?

Google allows a maximum of 6 ad schedules per day for each campaign.

Can I run ads overnight, from one day into the next?

Yes, with two entries. To run from Monday 11 PM to Tuesday 7 AM, schedule Monday 11 PM to 12 AM and Tuesday 12 AM to 7 AM.

Will turning off weekends lower my monthly spend?

Not by itself, since June 1, 2026. Google now paces towards 30.4 times the daily budget even when the schedule turns off some days, so lower the daily budget if you want to spend less in the month.
