Out of hoursOut of hours

At 23:47 on a Sunday, a sale lands in your network's report: publisher 41207, a £64.00 order, from a shopper who searched for your name.

At 10:04 on Monday you search your brand. Your own ad is at the top, with no other ads near it. The page is spotless, at ten in the morning. The ad that brought Sunday's sale has finished its shift.

Most brand checks happen in office hours, from a desk. An ad that runs only in the evening, overnight or at weekends can go unseen by anyone who only checks then. Here's how the schedule works, why Google's reports struggle with the night, and where it does show.

How the schedule works

An ad schedule sets the days and hours a campaign may serve. It's a standard setting on Search, Shopping, Performance Max, Display, Demand Gen and video campaigns, so any advertiser, an affiliate included, can run on your brand searches only in the evening, overnight or at weekends.

The schedule follows the advertiser's own account time zone, not yours and not the searcher's. That zone is fixed when the account is created and can't be changed, and the account's reports by time use it too. Imagine an account five hours behind London: its 18:00 is your 23:00. Your team's Monday morning isn't necessarily that account's Monday morning.

Start and end times go in quarter-hour steps (:00, :15, :30, :45), with up to six time blocks a day. A block can't cross midnight, so an overnight run takes two entries:

• Monday, 23:00 to 24:00
• Tuesday, 00:00 to 07:00

Two ordinary rows, nothing exotic. Ads stop serving exactly at the schedule's edges, though clicks can still be recorded for up to an hour after a window closes.

Smart Bidding, Google's automated bid strategies (Target CPA, Target ROAS, Maximise conversions, Maximise conversion value), ignores schedule bid adjustments, which otherwise run from −90% to +900%. It still follows the schedule itself, strictly. The on and off windows do the work: hours are switched off by leaving them out of the schedule.

Since 1 June 2026, a campaign switched off on whole days paces towards 30.4 times its daily budget a month, and can spend up to twice its daily budget on any day it runs. So a weekend-only campaign can spend double its daily budget on each day it's live. Schedules that only switch off certain hours aren't affected.

A schedule isn't the only clock. Automated rules can pause and enable a campaign Once, Daily, Weekly or Monthly at a set time, and may run up to two hours late. Schedules know days of the week, not dates, so going quiet around particular dates takes rules, scripts, end dates or pausing by hand.

Why your reports miss it

An empty results page at ten in the morning says nothing about ten at night. Your morning check can miss the entire run, and Google's own tools don't fill the gap.

Auction Insights, the report comparing you with other advertisers in your auctions, covers Search, Shopping and Performance Max. It splits by date, day of week, week, month, quarter and year, never by hour. A competitor under 10% impression share (the share of auctions it showed in) appears as “< 10%”, and a night-only bidder averaged over a month can sink below that line.

There's a harder limit underneath. Auction Insights only compares you with advertisers in auctions you entered. If your own brand campaign switches off overnight, the night's auctions aren't in your report at all. Round the edges meets the same limit from another side.

Ad Preview and Diagnosis has no clock either. It has settings for location, language and device, and none for time, so a daytime preview can't replay last night's auction. It shows you now.

Even your network can mislead if you read the wrong column. A sale's time isn't its click's time: sales can arrive hours or days after the click, within the cookie window (how long a click can still earn credit). A publisher whose clicks happen at night can show daytime sales.

What the night costs

If your own brand campaign switches off overnight, that paid placement is open to any other eligible advertiser. An affiliate's ad can reach someone already looking for your shop and earn commission on the sale.

Every one of those shoppers typed your name. If your terms allow a partner on brand search at set hours, that may be a price you agreed. If they don't, it's worth a question. Check your own coverage before anyone else's.

Finding the night in your own data

Start in your own account: open your brand campaign, set the range to the last 30 days and segment by Hour of day. Look at Avg. CPC. Imagine £0.23 a click at 10:00 and £0.47 at 21:00, with nothing in Change history on your side. A price that climbs every evening is a lead: another bidder's Ad Rank can push your cost per click up without you touching a bid.

Then run Auction Insights on your brand keywords over three to six months, segmented by day of week, and look for a domain that appears or gains share only on Saturday and Sunday.

In your network, take each publisher's transactions by click time, not sale time. Compare one publisher's share of clicks between 19:00 and 07:00, and at weekends, with the programme's own pattern. In GA4, the Hour and Day of week dimensions do the same for your sessions.

The ordinary explanations

An ad seen only at night usually has a plain reason behind it.

• A partner your programme allows on brand search at agreed hours, perhaps agreed before your time.
• Your own brand campaign switching off overnight, leaving the placement open to anyone eligible.
• Your agency, or another team at your company, running a campaign on a schedule.
• A time zone gap: an account hours behind London running what it thinks of as an evening schedule.
• A sub-network's publisher who didn't know your rules.
• An old campaign or automated rule still running after the arrangement behind it ended.

Each has a record behind it. Ask for it, with the times attached.

What to do

1. Check your own coverage: your brand campaign's ad schedule, and whether it serves all day, every day.
2. Note the time zone of your Google Ads account, your GA4 property and your network, and convert everything to London time.
3. Pull Avg. CPC by Hour of day for your brand campaign over 30 days, beside Change history for the same weeks.
4. Run Auction Insights on brand keywords over three to six months, by day of week.
5. Ask the network for transactions with click times, and compare each publisher's share of clicks from 19:00 to 07:00 and at weekends with the programme's.
6. Look at your brand search in the evening and at weekends too, without clicking any ad. Record each sighting: the time and time zone, the search, the device, the location, the ad as it read and the advertiser Google names in “About this advertiser”.
7. If partners may bid on your brand at set hours, write those hours into your terms. If none may, say so, at any hour.

For a documented case outside your terms, Google's Unfair advantage policy lists “affiliates that advertise on Google Ads against the applicable affiliate program rules”. What you can do covers that route and the evidence it needs.

Seeing it in Godotoro

For brands on its schedule, Godotoro searches google.co.uk for the bare brand name and “yourbrand discount code” every four hours by default, from 00:00 to 20:00 London time: six times a day, midnight and four in the morning included. “Voucher code” and “promo code” are searched weekly, and a check refreshes whatever is out of date.

Who's bidding counts, for each advertiser, how often it was seen in office hours (09:00 to 18:00 on weekdays, London time), out of hours and at night. A moon (☾) marks one seen only out of office hours, with the counts beside it: “Seen only out of office hours: 9 of 32 searches out of hours, 0 of 10 in office hours”.

Every ad carries the advertiser Google names for it, the identity to take to your network. Godotoro never clicks an ad. It describes what was seen, and what that means under your terms is for you to decide. To see your brand's nights, check your brand.
