Why is my Google Ads not working? 15 real reasons, fixes & audit checklist (2026)

If you've typed "Google Ads not working" into a search bar at 11 pm while staring at a dashboard full of spend and no sales, you're in good company. It's one of the most common frustrations in paid search, and almost always, the answer isn't "Google Ads is broken." It's that one (or several) predictable set of things has gone wrong.

We run Google Ads accounts for clients across trades, professional services, and local retail businesses, so this diagnosis is one we run constantly, the same checklist, in the same order, every time a client tells us their Google Ads has "stopped working."

This guide walks through that process: how the platform decides what to show, the 15 real causes behind most under performing accounts, how to check each one yourself, a free audit checklist, and when it's time to bring in a specialist.

Key Takeaways:

Google Ads usually "isn't working" for one of five root causes:

• You're targeting the wrong keywords or match types.
• Your ads and landing page aren't relevant enough to earn a good Quality Score.
• Your budget or bidding strategy is choking impressions
• Your conversion tracking is misreporting results,
• Your offer/landing page simply doesn't convert the traffic you're paying for.
• The sections below cover all 15, roughly ranked by how often we find them in practice.

How Google Ads Actually Works (the 60-second version)

Most of the 15 reasons below make more sense once you understand the mechanics they're breaking. In short:

1. Someone's search pattern. Google matches that search against your keywords (or, in Performance Max/Demand Gen, against your assets and signals) alongside every other advertiser targeting similar terms.
2. An auction runs. Your Ad Rank, a combination of your bid, your Quality Score, and the expected impact of ad extensions, decides whether your ad shows, in what position, and roughly what you'll pay per click.
3. Quality Score is the multiplier that makes or breaks the economics. Google's own documentation describes it as a diagnostic built from three components: expected click-through rate, ad relevance, and landing page experience. A high score means you pay less for a better position; a low score means you're outbid by competitors even with a bigger budget.
4. Bidding strategy decides how aggressively Google chases your goal. Manual and Smart Bidding strategies (Maximise Clicks, Target CPA, Target ROAS) all need a data-gathering "learning period" before they stabilize.
5. Conversion tracking closes the loop. Everything above is optimised toward whatever you've told Google to count as a conversion. So, if that signal is wrong, every downstream decision Google's algorithm makes will be wrong too.

Once you can place your problem somewhere in that five-step chain to diagnose “why your Google Ads isn't working", the issue becomes a lot less overwhelming.

Diagnose the type of problem you have

Before you assume Google Ads isn't working, separate the campaign that are "not showing" from those "showing but not converting”, they have completely different fixes.

• No impressions at all? Points to disapproved ads, an exhausted budget, overly restrictive targeting, or a Quality Score so low your ads aren't clearing the auction. See reasons 5, 10 and 11.
• Impressions but no clicks? An ad relevance or messaging problem. See reasons 5 and 6.
• Clicks but no conversions? A landing page, tracking, or offer problem. It’s not a Google Ads problem at all. See reasons 8, 12 and 15.

Google's Quality Score diagnostic tool is the fastest way to see which bucket you're in, because it breaks performance down into those same three components.

15 reasons your Google Ads isn't working

1. You're targeting the wrong keywords

This is the single most common reason we hear "my Google Ads isn't working." Broad, high-volume terms feel like the obvious choice, but they often bring in people who were never going to buy eg. browsers, job seekers, DIYers, or people searching for something adjacent to your service.

Diagnose it: Pull your search terms report and read the actual queries triggering your ads, not just the keywords you added. If most of the ads spend is landing on searches only loosely related to what you sell, this is your problem.

Fix it: Rebuild ad groups around tightly themed keyword clusters that mirror real buyer intent. Google's guidance on keyword prioritisation and query matching explains how Google decides which keyword competes in each auction, which makes it much easier to predict and control the searches you'll win.

2. You're using the wrong match types

Broad match sounds efficient. Google finds "similar" searches for you. However, in reality, it can pull in only loosely related queries, particularly on newer or lower-budget accounts that haven't built up enough conversion data for Smart Bidding to compensate.

Diagnose it: In the search terms report, filter by match type. If broad match keywords are generating high spend and low conversion rate relative to phrase/exact, that's your signal.

Fix it: For anything transactional, lean on phrase and exact match. Save broad match for well-optimised campaigns feeding a strong automated bidding strategy with a solid conversion history. The Search Engine Journal guide to query matching controls is a useful primer on how match types interact with Google's prioritisation logic.

3. You're not using negative keywords

This is the fastest, cheapest fix on this list, and the one most account skip. WordStream's analysis of over 15,000 Google Ads accounts found that accounts with even one negative keyword saw far higher conversion rates than accounts with none. Moreso, most accounts without negative keywords have been found to have wasted over £1,000/month on unqualified clicks.

Diagnose it: In the search terms report, sort by cost with zero conversions. Anything irrelevant sitting at the top is money you're actively leaking.

Fix it: Build a negative keyword list and apply it at the account level so it covers every campaign automatically. Google explains the mechanics in its guide to account-level negative keywords.

4. Your ads aren't relevant to the search

If your ad copy is generic and doesn't mirror the intent behind the keyword, people scroll past it, even in a good position. Check whether your headlines contain the terms people are searching for, and whether the offer in the ad matches what's on the landing page.

Diagnose it: Compare your Click-Through Rate (CTR) against Google's "Expected CTR" status in the Quality Score columns. "Below average" is a direct signal that relevance is the issue.

Fix it: Split ad groups by theme so each can run tightly targeted copy, rather than one generic ad serving ten search intents at once. This is standard structure advice covered well in PPC Hero's guide to Google Ads account structure.

5. Your Quality Score is poor

Quality Score isn't used directly in the auction, but it's the clearest public signal of how Google rates your ad-keyword-landing page relevance, and poor scores mean you pay more for worse positions.

Diagnose it: Add the Quality Score columns (Quality Score, Expected CTR, Ad Relevance, Landing Page Experience) to your keywords view and sort by spend. Anything below 5/10 with real spend behind it needs attention first.

Fix it: Work through each of the three components individually rather than trying to fix "Quality Score" as a singular problem. See Google's guide on using Quality Score to improve performance. Tighter ad groups (reason 4) do more for this metric than almost anything else.

6. Your account structure is a mess

A flat account with a handful of broad campaigns and huge, loosely themed ad groups makes every other problem on this list worse, it dilutes relevance, makes budget allocation blunt, and makes the search terms report almost impossible to action.

Diagnose it: Count the keywords per ad group. If you're seeing 30–50+ keywords spanning multiple product lines or services in one ad group, structure is likely capping your performance.

Fix it: Group keywords by tight themes, separate branded from non-branded traffic, and structure campaigns around business goals or locations rather than convenience. WordStream's 2026 guide to Google Ads account structure and PPC Hero's account structure guide both cover this in detail.

7. Your landing page doesn't convert

You can do everything else right and still lose the sale here. If the page is slow, unclear, or doesn't match what the ad promised. When visitors bounce on your landing page, Google notices too since landing page experience feeds Quality Score.

Diagnose it: Benchmark yourself honestly. Unbounce's analysis of 41,000 landing pages and 464 million visits puts the median landing page conversion rate at around 6.6%. Their piece on what counts as a good conversion rate explains why comparing your number against similar pages (not an arbitrary target) matters more than the raw figure.

Fix it: Prioritise message match (the headline should echo the ad), page load speed, and a single, obvious call to action. Cut form fields to the minimum you actually need.

8. You're attracting the wrong audience

Sometimes the keywords are right but the people behind them aren't your buyers. Also, wrong location, wrong budget, wrong stage of the buying journey. This shows up as decent click volume with poor lead quality.

Diagnose it: Cross-reference conversion rate by location and audience segment in your reporting. A specific area or audience dragging the account average down is usually visible within a few clicks.

Fix it: Layer in audience signals (in-market, affinity, remarketing) and tighten geographic targeting. If you're a local or regional business, narrow the location to where your service is one of the highest impact fixes available. Something we regularly do when auditing Local Service Ads and Search accounts for trades clients.

9. Your budget is too low

If your daily budget runs out by lunchtime, you're missing a sizeable chunk of the day's search volume, often the highest-intent evening or weekend searches, depending on your industry.

Diagnose it: Check "Lost impression share (budget)" in your campaign metrics. Anything above 10–15% on your best-performing campaigns is lost revenue, not saved money.

Fix it: Raise budget on proven campaigns, narrow targeting your highest-converting segments, or both. WordStream's account study found budget allocation and structure sophistication correlate strongly with overall performance,  it's rarely just about spending more, but about spending enough to compete for the searches that matter.

10. Your bidding strategy is fighting you

An overly aggressive Target CPA or Target ROAS goal can cause Google to throttle your impressions altogether. It simply stops showing your ad to people it doesn't think will hit an unrealistic target, which looks identical to "my ads have stopped working."

Diagnose it: Check "Lost impression share (rank)" alongside your Target CPA/ROAS setting. If it's high and you set a target well below your account's real average cost per conversion, this is almost certainly your issue.

Fix it: Give automated bidding strategies realistic targets based on actual historical cost-per-conversion, and don't switch strategies every few days. Each change resets part of the learning process. Search Engine Journal's piece on diagnosing dropping Google Ads clicks covers this bidding-friction pattern in more detail.

11. You're not tracking conversions properly

This is the sneakiest one, because everything can look broken when it's just unmeasured. AJAX-based form submissions, GTM misconfiguration, or a conversion tag that fires on the wrong page can all make a perfectly good campaign look like a failure, or worse, mislead Smart Bidding into optimising for the wrong signal entirely.

Diagnose it: Compare Google Ads conversions against GA4 conversions for the same date range and goal. A large, unexplained gap is a tracking issue, not a performance one.

Fix it: Verify your setup using Google's conversion tracking troubleshooter and conversion measurement guide. If your forms submit via AJAX/JavaScript without a page reload, double-check the conversion tag is firing on submission and not just on page load.

12. You're making changes too often

Every time you edit a bid strategy, budget, or key ad group setting, Google Ads re-enters a learning phase where performance can dip while the algorithm relearns your account's patterns. Tinkering daily out of anxiety is one of the most common ways well-intention advertisers sabotage their own results.

Diagnose it: Check your change history against your performance graph. If every dip lines up with a change you made the same week, this is your problem.

Fix it: Make one change at a time, then leave it for at least 7–14 days (longer for lower-volume accounts) before judging the result. Search Engine Journal's guide on diagnosing click drops makes the case for controlled testing over "all at once" swaps for exactly this reason.

13. Your competitors are simply outperforming you

Sometimes nothing in your account is wrong. It might just be that a competitor has entered the market, increased budget, or sharpened their offer, and the auction has become more expensive as a result.

Diagnose it: Pull your Auction Insights report and check for new entrants or rising overlap rate/top-of-page rate among existing competitors.

Fix it: Optmyzr's free Auction Insights Visualizer turns Google's raw auction data into readable charts, making it much easier to spot when competitive pressure, rather than your own account, is behind a performance dip.

14. Your offer isn't competitive enough

If your price, guarantee, or value proposition is simply weaker than what's shown alongside you on the results page, even a technically perfect campaign will underperform.

Diagnose it: Search your own keywords incognito and read the ads and landing pages around you like a customer would. Be honest about how yours compares.

Fix it: Small, testable changes, a stronger guarantee, clearer pricing, a lower-friction first step (like "get a free quote" vs "book a consultation"), often move the needle more than any bid or keyword tweak.

15. You're expecting results too quickly

New campaigns, new bidding strategies, and Smart Bidding in general all need a data-gathering window before they stabilise. Judging a campaign after three days is one of the most common (and most understandable) mistakes we see, particularly under pressure to show quick wins.

Diagnose it: Check the campaign or strategy start date against your performance dip. If it's within the first 1–2 weeks, this is likely the learning phase, not a genuine failure.

Fix it: Give a new campaign or significant change at least 2–4 weeks, and more if your conversion volume is low, Smart Bidding strategies typically need a decent volume of conversions per month to exit the learning phase reliably.

Not sure if it's Google Ads or your website? Get a free audit

Point 7 on this list, landing pages that don't convert, is the one issue we can't fully diagnose from inside the Google Ads dashboard, because the problem usually sits on your website rather than in your campaign settings.

Slow website/landing page load times, unclear messaging, weak call to action, and poor mobile layout will all suppress conversions no matter how well the rest of the account is built.

If you've worked through the audit checklist above and everything in Google Ads looks correct, the next step is to check the site itself. We offer a free website audit that reviews speed, structure, and on-page factors that affect both SEO and paid traffic conversion, a useful sense check before you spend more on clicks that a slow or unclear page was always going to waste.

Mistakes we see most often in client accounts

A few patterns come up repeatedly enough across different industries that they're worth calling out on their own:

• Trade and home services (heating, solar, installers): Location targeting left far wider than the actual service area, meaning budget is spent on enquiries the business can never fulfil. Also common: no call tracking, so phone enquiries, often the majority of conversions for trades, aren't counted at all, making the account look far less effective than it is.
• Specialist/professional services (therapy, legal, consultancy): Ad copy and landing pages that focus on service descriptions rather than the specific concern the searcher typed in. A page titled "Our Services" converts worse than a page titled to match the exact query that brought someone there.
• Local retail and niche ecommerce (antiques, boutique products): Category-level keywords competing against national retailers on price, when long-tail, descriptive terms ("Victorian brass table lamp" vs "table lamp") convert at a fraction of the cost with far less competition.
• Every industry, constantly: Conversion actions set up once at launch and never revisited, so the account is still optimising toward a goal (like "page view" or "contact form load") that stopped being the real business objective months ago.

Real examples: how we diagnosed three "not working" accounts

These are anonymised, composite patterns drawn from real diagnostic work. Details have been anonymised to protect client confidentiality, but the root causes and fixes are exactly as we found them.

Example 1:  “We're getting clicks but Google Ads isn't converting."

A tender-writing and bid-preparation service saw steady clicks but a stark mismatch between Google Ads' reported conversions and Google Analytics 4's numbers. The cause: the enquiry form submitted via AJAX without a page reload, and the conversion tag was set to fire on a URL change that never happened. Google Ads was reporting far fewer conversions than were happening, and, worse, Smart Bidding was being starved of the signal it needed to optimise properly.

Fixing the tag to fire on the form's actual submission event resolved both the reporting gap and within a few weeks, the bidding performance.

Example 2: Local Service Ads with high spend, low-quality leads.

A trades business running Local Service Ads was generating leads well outside its genuine service radius, alongside broad keyword messaging that didn't distinguish between service types.

Narrowing geographic targeting to the specific counties served, correcting keyword-message alignment, and disabling irrelevant service categories brought lead quality up sharply without increasing spend.

Example 3: App install campaign with strong clicks, weak reported installs.

A cashback app install campaign showed strong click-through rates but installed lagging expectations. Coordination with the client's mobile SDK provider revealed the install-tracking integration hadn't been fully verified end-to-end, meaning a portion of genuine installs simply weren't attributed back to the campaign.

Once the SDK-to-Ads connection was confirmed and tested, reported performance caught up with what the click data had been suggesting all along.

The common thread in all three: the campaigns weren't broken. The measurement was.

When to hire a Google Ads Specialist

Working through this guide yourself is entirely realistic if you're comfortable spending a few hours a week on the platform. It's worth bringing in a specialist when:

• You've worked through the audit checklist above and still can't find the issue
• Conversion tracking discrepancies persist after basic troubleshooting (this often needs GTM/GA4 expertise, not just Google Ads knowledge)
• You're managing multiple campaigns or a growing budget and don't have the time to review performance weekly
• You want a second opinion before committing to a bidding strategy change or Performance Max migration
• The account has history you didn't set up yourself and you're not confident in its structure

A good specialist should be able to walk you through exactly which of the 15 reasons above applies to your account, with evidence from your own data, not just generic recommendations. Our Google Ads management service covers Search, Shopping, Display, Local Service Ads, and Performance Max, and every account starts with an audit against this same checklist before we recommend anything.
