Google Ads campaigns fail quietly. Nothing crashes, no red banner fills the screen, the account simply stops producing impressions and the phone stops ringing. If you are asking why your Google Ads are not showing, the answer is almost always one of a short list of causes, and each has a specific place in the account where you can confirm or rule it out. This guide walks through them in the order that finds the fault fastest, with the checks a UK business owner can run in under an hour.
Why can I not see my Google ad when I search for it?
Google's help page for the Ad preview and diagnosis tool explains that the tool exists so advertisers can check eligibility while avoiding accumulating ad impressions and impacting performance statistics. Every time you search for your own ad and do not click, you log an impression with no click, and your click-through rate drops a little further. Do that thirty times in a week and you have trained the account to think the ad is unappealing.
Open the tool under Tools, then Troubleshooting. Type the keyword you expect to trigger the ad, set the location to a town you target rather than your own postcode, pick the device, and run it. Three outcomes matter. If the ad is showing, the campaign is fine. If the ad is eligible but not showing on this search, the tool will say why, and the reasons below explain the fix. If the tool cannot find your keyword, you may be searching a phrase that is not in the account at all, which is a common surprise after a colleague has tidied the keyword list.
Is my ad still under review or disapproved?
Google's page on the ad review process sets the expectation clearly. Most ads clear within one business day, some take longer if a more complex review is needed. If yours has sat in review for more than 2 full business days, check the status for a specific message. If it passes a week, contact Google Ads support. UK bank holidays and weekends do not count, so an ad submitted on the Friday before the August bank holiday can legitimately stay in review until the following Tuesday.
Two habits cause needless delay. The first is editing the ad while it is under review, because any change to the ad or its assets restarts the clock. The second is ignoring the Eligible (limited) status, which means the ad runs in some places but not others, often because of restricted categories such as alcohol, healthcare or financial services. A Cheshire wine merchant, a Leeds physiotherapy clinic or a Bristol mortgage broker will each hit this and each needs the relevant certification or policy step completed before the ad serves fully.
If the ad is Disapproved, hover over the status to read the policy named. Trademark use in headlines, a landing page that does not match the ad, and missing contact details on the site are the most frequent UK small business disapprovals. Fix the cause, then resubmit rather than duplicating the ad, because the duplicate inherits the same problem.
Has my campaign run out of budget for the day?
Google's help page on average daily budgets describes two limits. The daily spending limit is two times your average daily budget for most campaigns. The monthly spending limit is 30.4 times your average daily budget. So a campaign set to £10 per day can spend £20 on a Tuesday when searches spike, but Google will pull back on other days so that the month lands at £304 or under.
The practical symptom is ads that show at 9am and vanish by early afternoon. Look at the campaign row for the words Limited by budget, then open the Overview and switch the chart to hourly. If impressions collapse at the same hour every day, you have your answer. You can raise the budget, but the better first move is often to cut. Remove the broad keywords that spend without converting, add negatives for the searches that were never going to buy, and set an ad schedule so the budget is only spent during the hours your team can answer the phone.
Is my bid too low to win the auction?
Check the keyword-level Status column for the messages Below first page bid or Low search volume. The first tells you the bid is not competitive for that term. The second means Google has paused the keyword because too few people search it, which is common for hyper-local phrases such as a service plus a small village name.
Before raising bids, improve the quality side. Group keywords into small ad groups with one clear theme, write headlines that repeat the keyword, and send the click to a page about that exact service rather than the homepage. A Birmingham electrician bidding on emergency electrician Birmingham should land on a page that says emergency electrician in the heading, shows a phone number above the fold, and loads fast on a phone in a car park. That work raises Quality Score, which lowers the bid needed to show. The guide on AI tools for plumbers and electricians covers how trades can build those pages without a full site rebuild.
For a sense of what competitive looks like, the WordStream by LocaliQ 2026 Google Ads benchmarks report an average click-through rate of 6.64% across all industries for search campaigns between April 2025 and March 2026, with an average cost per click of $5.42 and an average conversion rate of 8.18%. Those are US dollar figures drawn mainly from US campaigns across a broad mix of sectors, so treat them as a rough yardstick rather than a UK target, but a search campaign sitting well under that click-through rate is usually paying more per click than it needs to.
Am I targeting the wrong location, language or device?
Open the campaign settings and read the Locations panel slowly. Three UK-specific traps come up again and again. The first is a radius drawn around the business address rather than the area customers come from, which suits a café but not a plumber who drives forty minutes each way. The second is a target of United Kingdom on a campaign meant for one city, which does not stop ads showing but spends the budget in London before your local town gets a look in. The third is the location options setting under advanced, where Presence or interest lets people in another country who searched your town see the ad and burn budget.
Devices deserve a glance too. A minus 100 percent bid adjustment on mobile, sometimes left over from an old agency setup, removes most local searches in one stroke. Set adjustments back to zero, let the campaign run a fortnight, then decide from the data.
Are negative keywords or ad schedules blocking my ads?
Negatives live in three places: the keyword, the campaign, and shared negative lists applied at account level. Someone adding free as a broad match negative to stop bargain hunters will also block searches for free quote and free callout, which are exactly the queries a UK tradesperson wants. Check the Negative keywords tab in each campaign and the Shared library for lists applied across the account.
Ad schedules are simpler to spot. Open the Ad schedule tab and look at which days and hours are ticked. A schedule copied from a solicitor's office campaign will not suit a takeaway that does most of its business after 6pm. If in doubt, remove the schedule, let the ads run all week, and add limits back once the hourly report shows when conversions actually arrive.
Could billing or account status be the problem?
Billing failures are the cause that catches the most experienced advertisers because nothing changes in the campaigns themselves. The status column still says Eligible. The budget still looks fine. Meanwhile the card that was used to set up the account has been replaced after a fraud alert, and Google has stopped serving until the balance clears.
Advertiser verification is the other quiet blocker. Google asks UK advertisers to verify their identity and business details, and an account that ignores the verification deadline can have its ads paused. The notice sits in the bell icon at the top of the account and in the email attached to the login, which is often an old address nobody checks. Set a calendar reminder to look at the notifications once a week.
Account suspensions are rarer and louder. They come with a banner and an email naming the policy. Circumventing systems and unacceptable business practices are the ones that catch small businesses, usually because a previous agency ran something questionable on the same payment profile. Appeal through the form in the banner rather than opening a new account, since a new account linked to the same details will be suspended too.
What order should I check things in to find the fault fastest?
A practical sequence for a UK small business that has just noticed the phone has gone quiet looks like this.
- Open the Ad preview and diagnosis tool, enter your top keyword and target town, and read the diagnosis.
- Look at the campaign, ad group and ad rows for Paused, Under review, Disapproved or Eligible (limited).
- Open Billing, Summary, and confirm the payment method is valid and there is no outstanding balance.
- Open the campaign Overview, switch to hourly, and check whether impressions stop at the same time each day.
- Read the Locations, Languages and Devices settings, including the advanced location options.
- Read every negative keyword list and the ad schedule.
- Open Change history filtered to the week the ads stopped and see what moved.
- Only now look at bids, Quality Score and the Below first page bid message.
Most faults are found by step three. Bids, the thing most people jump to first, are the last item because raising a bid on a campaign that is disapproved or unfunded changes nothing except future spend.
How do I stop this happening again?
The accounts that stay healthy are not the ones with the cleverest bidding. They are the ones where somebody looks at them regularly and knows what normal looks like. Write down the baseline: impressions per day, clicks per day, cost per day and calls per day for a typical week. When any of those drops by half, you notice inside a day rather than at month end when the accountant asks why the enquiries dried up.
If you run a trade, the wider setup around the campaign matters as much as the campaign. The guide on AI tools for UK tradespeople covers how to answer the leads the ads produce once they arrive. If you would rather hand the account to someone who checks it every week and reports in plain English, the paid media service page sets out how that works.
Google Ads rarely breaks in a dramatic way. It stalls on a review, runs out of budget by lunch, targets the wrong town or loses its card. Every one of those is visible in the account within minutes if you know where to look, and the order above finds them without guesswork.
Why Are My Google Ads Not Showing? UK Fixes — FAQ
Why can I not see my own Google ad when I search for it?
Searching for your own ad is the least reliable test there is. Google shows ads based on your location, device, search history, time of day, the campaign's remaining budget and the auction on that exact query, so a perfectly healthy campaign will often not appear for you. Worse, every search you run without clicking registers an impression, which drags down your click-through rate. Google's own guidance on the Ad preview and diagnosis tool says to use the tool precisely because it avoids accumulating ad impressions and impacting your performance statistics. Open it under Tools, Troubleshooting, type your keyword, set the location to the town you target, and read the diagnosis. If it says the ad is eligible, the campaign is working even if you personally cannot see it.
How long does Google Ads review take in the UK?
Google's ad review help page states that most ads are reviewed within one business day, with some taking longer if the ad needs a more complex review. The same page says to check the ad's status if it has been under review for more than 2 full business days, and to contact Google Ads support if it has been under review for more than a week. UK bank holidays and weekends do not count as business days, so an ad submitted on a Friday evening before a long weekend may not clear until the following Tuesday. Every edit to an ad or asset restarts the review, so avoid tinkering with copy while you wait.
Why do my ads stop showing in the afternoon?
Almost always budget. Google spreads your average daily budget across the day, and once the campaign has spent what it can, ads pause until midnight in the account's time zone. Google's average daily budget help page explains that a campaign can spend up to two times the average daily budget on a busy day, but no more than 30.4 times that budget in a calendar month. If your keywords are expensive and your daily budget is small, the money is gone by lunchtime. Look for the Limited by budget status on the campaign row, then either raise the budget, narrow the keyword list, or restrict the ad schedule to the hours that convert.
Does a low Quality Score stop my ads showing at all?
It can. Google runs an auction for every search, and your position is decided by Ad Rank, which combines your bid with the expected quality of your ad and landing page. If your keyword has a low Quality Score and a modest bid, your Ad Rank may fall below the threshold needed to appear on the page at all, so you get very few impressions rather than a low position. The fix is not always a higher bid. Tighten the match between keyword, headline and landing page, group keywords into smaller themed ad groups, and make sure the landing page loads quickly on mobile. Check the keyword's status column for the phrase Below first page bid or Low search volume, which points to the specific cause.
My campaign says Eligible but has zero impressions. What now?
Eligible means the ad passed policy review. It does not mean the ad is winning auctions. Work through four checks. First, confirm the keywords are not marked Low search volume, which suspends them until searches pick up. Second, check location targeting, because a campaign set to a single postcode radius in a rural area may see almost no searches. Third, open the negative keyword lists at campaign and account level, since one broad negative can silently block every query. Fourth, check billing under Billing, Summary, because a declined card or an unverified payment profile stops serving without a loud warning. The Ad preview and diagnosis tool will usually name which of these is the problem.
