Why your Google Ads aren’t working (and how to fix them)

If it feels like you are pouring money into Google Ads and getting little back, you are probably right, and it is almost always one of a handful of specific, fixable faults. This is the diagnostic.

“Not working” is a feeling. To fix it you need to turn it into a specific fault. This guide does that: it names the five symptoms, traces each to its real root cause, and tells you what to actually do. None of these problems are exotic. All of them are diagnosable. Use the contents to jump to your situation.

First, define “not working”

“My Google Ads are not working” describes at least five different problems, and the fix for each is different. Before changing anything, identify which one you actually have:

  • Clicks but no conversions: traffic is arriving, nothing is converting.
  • Budget burning fast with little to show: spend disappears quickly, results do not follow.
  • Wrong leads: the phone rings, but with people you cannot help.
  • Impressions but no clicks: ads show, nobody clicks (low CTR).
  • It worked, then stopped: performance was fine and quietly declined.
Why this step matters
Most wasted “fixes” happen because the owner changed something before knowing which problem they had. Diagnosis before action is the entire discipline. Skipping it is how accounts get worse while everyone is busy.

The five symptoms, diagnosed

Find your symptom. Each card gives the most likely cause and the first thing to do. The deeper root-cause sections follow.

Clicks but no conversions
Most likely cause
Broken or missing conversion tracking, a landing page that does not deliver on the ad, or loose targeting bringing the wrong intent.
What to do
Verify conversion tracking first, before touching anything else. If tracking is sound, check that the landing page matches the ad\u2019s promise and has one clear next step.
Budget burning fast, little to show
Most likely cause
Broad match keywords and thin negative-keyword coverage flooding the account with low-intent clicks, or a bid strategy chasing volume.
What to do
Pull the search terms report and see what people actually searched. Add negatives aggressively, tighten match types, and check the bid strategy matches the goal.
Wrong leads coming in
Most likely cause
Location targeting set wider than you serve, or keywords matching adjacent searches that look relevant but are not.
What to do
Lock location targeting to your real service area and review the “presence or interest” setting. Then mine search terms for the queries pulling the wrong people.
Impressions but almost no clicks
Most likely cause
Low ad relevance and Quality Score: the ad does not match the search, or keywords are too broad to write a tight ad against.
What to do
Tighten ad groups so each one is about one thing, rewrite ads to match that intent, and cut broad keywords you cannot write a relevant ad for.
It worked, then stopped
Most likely cause
Account decay: a competitor changed bids, tracking broke after a site update, search behaviour shifted, or automation drifted.
What to do
Check conversion tracking still fires, review recent changes and the change history, and compare current search terms and competition to when it was working.

Root cause 1: broken or missing tracking

This is the most damaging fault and the most common, because it is invisible. If conversions are not tracked accurately, the account optimises toward bad data, and every other number you look at is unreliable. You can be “fixing” an account that was never measuring the right thing.

It breaks quietly. A website redesign, a new cookie banner, a changed thank-you page, a tag that got removed, all can stop conversions recording without any error message. The campaign keeps spending; the data just stops being true.

  • Conversions dropped to zero or spiked unrealistically right after a website change.
  • Google Ads conversion numbers do not reconcile with the enquiries or sales you actually received.
  • Nobody can clearly explain what a “conversion” in the account is even counting.
Fix this before anything else
Until tracking is verified, do not optimise, do not judge performance, do not cancel. Every decision rests on this. It is the first thing a competent audit checks for exactly this reason.

Root cause 2: targeting too wide

The most expensive setting in the account, and the easiest to get wrong. Targeting wider than you can serve means paying for clicks that could never become customers. For a local business this single fault can consume a large share of the budget.

It hides in three places: geographic targeting set to a province or country when you serve a suburb, the “presence or interest” location option left on its broad default, and broad match keywords with weak negatives pulling in unrelated searches. Each quietly widens who you pay for.

The local-business trap
If you serve a specific area, every click from outside it is pure waste. Fixing location targeting alone has turned around accounts that looked beyond saving. A real, anonymised example is on the results page.

Root cause 3: structure and Quality Score

A flat, sprawling account where everything is lumped together cannot be optimised, because there is no clean signal to act on. Structure is what makes everything else possible.

When ad groups mix unrelated keywords, you cannot write an ad that is tightly relevant to all of them. Ad relevance drops, Quality Score drops, and you pay more for worse positions. The fix is structural: tight, themed ad groups where keywords, ads and landing pages all point at one intent. This is also why a well-built smaller account routinely beats a bigger, messier one.

Quality Score is not vanity
It directly changes what you pay. Two advertisers bidding the same amount get different costs and positions based on relevance. Structure is how you earn the cheaper side of that.

Root cause 4: the landing page

The account is only half the system. The other half is the page the click lands on, and it is where a large share of “not working” actually lives. Perfect targeting into a weak page still fails.

  • Mismatch: the ad promises one thing, the page is about something broader. Every generic-homepage destination is this fault.
  • Friction: slow load, confusing layout, no obvious next step, or a form nobody wants to fill in.
  • No single action: the visitor is not told clearly what to do next.

If the ads bring relevant traffic but conversions do not follow and tracking is sound, the page is the prime suspect. Service-specific pages that match the ad are part of the campaign, not an optional extra.

Root cause 5: nobody is managing it

The quiet killer behind most of the above. Google Ads is not a switch; it is a system that decays. Competitors change bids, new irrelevant search terms appear weekly, tracking breaks after site changes, automation drifts. An account that is “running” but not actively managed is slowly getting worse the entire time.

The most common version in South African SMBs: a cheap monthly fee paid to someone who set the account up once and barely touches it. The fee feels small, so it goes unquestioned, while the full ad budget is spent badly month after month. Paying for ads and paying a manager and getting poor results from both is worse than running nothing.

“It worked then stopped” almost always means this
Decay is the signature of absent management. The fix is not a new tactic, it is someone actually working the account on a cadence.

How to diagnose it yourself, in order

Work the checklist top to bottom. The order matters: each step assumes the ones above it are sound, because a fault higher up makes everything below it unreadable.

  • 1. Conversion tracking. Is it firing, accurate, and reconciling with real enquiries or sales? If not, stop and fix this first.
  • 2. Location and targeting. Are you only paying for people you can serve? Check geo settings and the presence/interest option.
  • 3. Search terms report. What did people actually type? Irrelevant queries here are money burning now.
  • 4. Structure and relevance. Is each ad group about one thing, with ads that match? Is Quality Score weak?
  • 5. The landing page. Does it match the ad, load fast, and have one clear next step?
  • 6. Recent changes. What changed around the time it declined? The change history often holds the answer.
This is what an audit is
A free audit is this checklist run properly by someone who does it daily, with the findings ranked by impact. The honest version is described on the audit service page, and the underlying mechanics are in the complete Google Ads guide.

The “fixes” that quietly make it worse

Frustration produces a predictable set of moves that feel productive and usually deepen the hole. If you are doing any of these, stop before you do more.

  • Pausing and restarting repeatedly. Every restart can re-trigger a learning phase. Stop-start cycles keep the account permanently in its most expensive, least efficient state. It feels like control; it is self-inflicted cost.
  • Raising the budget to “force” results. More budget into a broken account just buys more of the same bad clicks faster. Spend amplifies whatever the account already does, good or bad.
  • Adding more keywords. The instinct is “reach more people”. The effect is usually a looser, lower-intent account that wastes more. Underperforming accounts almost always need fewer, tighter keywords, not more.
  • Switching bid strategy weekly. Automated strategies need stable conversion data and time. Changing them constantly resets learning and guarantees instability.
  • Turning everything on (Display, Search Partners, broad match) to “test”. This floods the account with low-quality traffic and makes diagnosis harder, not easier.
The discipline
When an account is not working, the right move is almost always to subtract and tighten, not add and broaden. Change one thing, with a reason, and let it run long enough to read. Thrashing is the most common way frustrated owners turn a fixable account into a write-off.

How long before you should worry

Half of “it is not working” is impatience reading the learning phase as failure. The other half is genuine faults left running for months. Knowing which is which comes down to timeline.

  • Days 1-14: learning phase. Cost per acquisition looks worse than it will be. This is normal. Do not judge, do not panic, do not cancel.
  • Weeks 3-6: the account should start showing direction. If there is genuinely zero signal of improvement and tracking is verified sound, now is the time to diagnose properly.
  • Weeks 7-12: performance should be stabilising and improving. Persistent poor results here, with sound tracking, point to a real structural fault, not bad luck.
  • Months, not improving: this is not “needs more time”. This is an unmanaged or broken account, and time alone will not fix it.
“Give it time” has a condition
Time only helps an account that is being actively managed. Time on a broken, unmanaged account just spends more money badly. The phrase is a reason to wait, not an excuse to ignore.

Fix, rebuild, or stop?

Once you know the fault, there are only three honest answers, and choosing the wrong one wastes more money.

  • Fix: the structure is sound and the problem is specific, broken tracking, a targeting setting, a weak page. Most accounts are here. Targeted fixes, not a teardown.
  • Rebuild: the account is so flat, mistargeted or tangled that optimisation has nothing to build on. Rebuilding beats endlessly patching.
  • Stop: the economics genuinely do not work, margins too thin, no real search demand, no trackable value, and no fix changes that. Stopping is the right call, and an honest specialist will say so.

The wrong move is the frustrated one: pausing and restarting repeatedly, which keeps the account permanently in its most expensive learning state, or rebuilding when a small fix would have done it. Diagnose first, then choose deliberately.

Frequently asked questions

Why are my Google Ads getting clicks but no conversions?
The click is working; something after it is not. The usual causes, in order: conversion tracking is broken so conversions are happening but not recorded, the landing page does not match the ad\u2019s promise, the traffic is the wrong intent because keywords or match types are too loose, or the offer itself is weak. Check tracking first, because if it is broken every other number is unreliable.
Why are my Google Ads spending so fast?
Usually broad match keywords or loose targeting pulling in a flood of low-intent clicks, an unrealistic bid strategy chasing volume, or no negative keywords filtering waste. Fast spend with poor results is almost always a targeting and structure problem, not a budget that is too small.
What is a good click-through rate, and why is mine low?
For search campaigns, above roughly 5% is generally healthy and brand terms run much higher. A low CTR usually means the ad does not match the search intent, the keywords are too broad, or ad relevance and Quality Score are weak. It is a relevance signal, not the goal in itself.
My Google Ads worked before and stopped. What changed?
Accounts decay. Competitors raised bids, search behaviour shifted, new irrelevant search terms crept in, conversion tracking silently broke after a website change, or an automated bid strategy drifted. “It worked then stopped” is the classic signature of an unmanaged account, not a platform fault.
How do I know if my conversion tracking is broken?
Signs: conversions suddenly dropped to zero or spiked unrealistically after a site change, the numbers in Google Ads do not reconcile with actual enquiries or sales, or you cannot explain what a “conversion” is even counting. Broken tracking is the single most damaging fault because the account optimises toward bad data.
Why am I getting the wrong kind of leads?
Almost always targeting or intent. Location targeting set wider than you serve, broad keywords matching unrelated searches, or no negative keywords. The fix is tightening location, match types and negatives so the budget only reaches people who can actually become customers.
Should I pause my campaign if it is not working?
Rarely the right first move. Pausing resets momentum and often forces a fresh learning phase on restart, making things more expensive. Diagnose and fix the specific fault first. Pause only when the economics genuinely do not work and no fix changes that, not out of frustration.
Can a bad agency be the reason my Google Ads do not work?
Yes, and it is common. The pattern: a low fee, an account that is set up once and never truly managed, vanity reporting that hides the lack of work, and slow decay nobody flags. An independent audit usually surfaces this within an hour.
Is Performance Max the reason my account is underperforming?
It can be. Performance Max is powerful but opaque, and without trustworthy conversion data and proper exclusions it tends to spend into low-value placements and brand searches you would have won anyway. It needs careful setup, not a default “on”.
How long should I give Google Ads before deciding it does not work?
Judge over 60 to 90 days of active management, not days or weeks. The first two to four weeks are a learning phase and are not a clean read. But “give it time” is only valid if the account is actually being managed; time alone does not fix a broken setup.
Why is my Quality Score low and does it matter?
It matters: a low Quality Score means you pay more for worse positions. It is usually low because keywords, ads and landing pages are not tightly aligned, or you are sending traffic to a generic homepage. Tightening that relevance chain is the fix, and it lowers cost while improving position.
Could my website, not my ads, be the problem?
Frequently, yes. If the ads bring relevant traffic but the page is slow, confusing, mismatched to the ad, or has no clear next step, the campaign cannot convert no matter how well it is run. Diagnosing “not working” means looking past the account to the page the click lands on.
Will adding more keywords or budget fix a struggling account?
Usually the opposite. More budget amplifies whatever the account already does, including the waste. More keywords typically loosen targeting and bring lower-intent traffic. Struggling accounts almost always need subtraction and tightening first, not expansion.
I keep pausing and restarting my campaigns. Is that a problem?
Yes. Restarting often re-triggers a learning phase, so frequent stop-start cycles keep the account permanently in its most expensive, least efficient state. Diagnose and fix the underlying fault instead of cycling the on switch.
How do I tell impatience from a real problem?
Timeline. The first two to four weeks are a learning phase and are not a clean read. By weeks three to six there should be direction; by weeks seven to twelve, stabilising improvement. Persistent poor results past that, with sound tracking, is a real fault, not a patience issue.
Should I get a second opinion on my account?
If you are unsure whether it is working and your current provider only reports activity, yes. An independent audit run by someone who does it daily usually surfaces the specific faults within an hour, and the findings are useful even if you never hire them.
