Most Google Ads accounts quietly bleed money. Not because the platform doesn't work, but because things drift. Campaigns that made sense six months ago stop performing. Keywords accumulate like barnacles. Conversion tracking breaks and nobody notices for weeks.
A proper audit fixes that. It's a systematic check of every moving part in your account — and it doesn't need to take days. Set aside a few hours, follow these steps, and you'll walk away knowing exactly where your money's going and what to fix first.
1. Review Your Account Structure
Before you look at any numbers, zoom out. Open your account and look at how it's organised.
A well-structured account groups campaigns by clear themes — by product line, service type, geography, or funnel stage. Each campaign should have tightly themed ad groups, with each ad group targeting a focused cluster of related keywords.
What to look for:
- Bloated ad groups — if an ad group has 30+ keywords covering different topics, it needs splitting. You can't write relevant ad copy for a group that targets both "emergency plumber London" and "boiler installation quotes."
- Campaign sprawl — old campaigns left running with tiny budgets, duplicated campaigns from past experiments, or campaigns with no clear purpose.
- Naming conventions — if you can't tell what a campaign targets from its name, rename it. Future you will be grateful.
A clean structure makes everything else in this audit easier. If your account is a mess structurally, sort that before optimising anything else.
2. Check Your Conversion Tracking
This is the single most important step. If your conversion tracking is broken or incomplete, every decision you make based on your data will be wrong.
Run through this checklist:
- Are conversions actually firing? Go to Tools > Conversions and check the status column. Look for "No recent conversions" or "Inactive" tags.
- Are you tracking the right actions? Phone calls, form submissions, purchases — whatever matters to your business should be tracked as a primary conversion. Newsletter signups and page views should be secondary at most.
- Is the attribution model sensible? If you're still on last-click attribution, consider switching to data-driven or at least position-based. Last-click undervalues everything at the top of the funnel.
- Google Tag check — open your site, fire up Google Tag Assistant or the browser's developer console, and confirm tags are loading on the correct pages. Pay particular attention to thank-you pages and confirmation steps.
If you find broken tracking, fix it before drawing any conclusions from the rest of the audit. Garbage in, garbage out.
3. Audit Your Keyword Strategy
Keywords are where most of the wasted spend hides. This step takes the longest but usually delivers the biggest savings.
Match types
Check the balance of your match types. Broad match can work brilliantly with smart bidding and solid conversion data, but if you're running broad match on manual CPC with thin conversion history, you're probably paying for a lot of irrelevant traffic.
Search terms report
Pull the search terms report for the last 90 days. Sort by cost and read through it. You're looking for:
- Irrelevant queries eating budget — add these as negative keywords immediately.
- Patterns — if you keep seeing the same irrelevant theme (e.g., "free," "jobs," "DIY"), create a negative keyword list for it.
- Hidden gems — search terms converting well that you haven't explicitly targeted. Add them as exact match keywords.
Negative keywords
Check your negative keyword lists. Most accounts don't have enough of them. If you've never built out negatives properly, this single step can cut wasted spend by 10-20%.
Also check for conflicts — make sure your negatives aren't accidentally blocking keywords you actually want to bid on. Google's "Search keywords" report under Recommendations sometimes flags these.
4. Review Ad Copy and Extensions
Open each ad group and look at the ads running in it.
Questions to ask:
- Do you have at least 2-3 responsive search ads per ad group? Google needs options to test.
- Are headlines relevant to the keywords in that ad group? Generic headlines reduce quality score and click-through rate.
- Are you using all available ad extensions? Sitelinks, callouts, structured snippets, call extensions, location extensions — each one gives you more real estate on the results page and typically improves CTR.
- Is the call to action clear? "Get a Free Quote," "Book a Consultation," "Shop Now" — the user should know exactly what happens when they click.
Check the asset performance ratings on your responsive search ads. Pin or replace anything rated "Low" and test new variations of your best-performing headlines.
5. Assess Landing Page Quality and Relevance
Your ads are only half the equation. If someone clicks through and lands on a page that doesn't match what the ad promised, they'll bounce — and you've paid for nothing.
For each major campaign, check:
- Message match — does the landing page headline reflect the ad copy? If your ad says "Get a Free Roof Inspection" and the landing page is your generic homepage, that's a problem.
- Page speed — run your landing pages through PageSpeed Insights. Slow pages kill conversion rates and hurt your quality score.
- Mobile experience — load the page on your phone. Is the form easy to fill in? Is the CTA visible without scrolling endlessly? Is the text readable?
- Clear conversion path — can a visitor complete the desired action (call, form, purchase) within seconds of landing? Remove friction wherever possible.
Google explicitly factors landing page experience into your quality score, so this isn't just about conversions — it directly affects what you pay per click.
6. Analyse Bidding Strategy and Budget Allocation
Open each campaign and check what bidding strategy it's using. Then ask yourself whether it still makes sense.
Common issues:
- Manual CPC on campaigns with enough conversion data — if a campaign gets 30+ conversions per month, it's usually a candidate for target CPA or maximise conversions.
- Maximise clicks on campaigns where you care about conversions — this strategy optimises for volume, not value. Fine for brand campaigns or awareness, but risky for lead generation.
- Budgets spread too thin — if you've got ten campaigns each with a fiver a day, none of them have enough budget to learn or compete effectively. Consolidate spend into your best performers.
- Limited by budget — check the "Limited by budget" status. If your best-converting campaign is budget-limited while a poor performer has headroom, reallocate.
Look at impression share data too. If you're losing significant impression share to budget on high-converting campaigns, that's a clear signal to shift money around.
7. Check Geographic and Demographic Targeting
Open your location settings and make sure you're targeting the right areas — and, crucially, that you've selected "Presence: People in or regularly in your targeted locations" rather than the default "Presence or interest," which will show your ads to people merely searching about your area.
Also review:
- Location performance — are certain regions converting better than others? Consider bid adjustments or separate campaigns for your best and worst areas.
- Demographic data — check age, gender, and household income breakdowns (where available). If a demographic segment is spending heavily with zero conversions, consider excluding or reducing bids.
- Device performance — mobile vs. desktop vs. tablet. If mobile converts at a fraction of desktop's rate, apply a negative bid adjustment rather than paying the same per click.
8. Review Quality Scores Across Keywords
Quality score isn't just a vanity metric — it directly affects your cost per click and ad position. A keyword with a quality score of 10 can pay roughly half the CPC of one scoring 5.
Filter your keywords by quality score and focus on anything below 6. For each low-scoring keyword, check the three components:
- Expected CTR — is the ad compelling enough? Improve headlines and descriptions.
- Ad relevance — does the ad copy closely match the keyword? You may need tighter ad groups.
- Landing page experience — is the landing page relevant, fast, and useful? (See step 5.)
Don't chase perfect 10s everywhere — focus on your highest-spend, highest-value keywords first. Improving quality score on a keyword that costs you hundreds a month is far more valuable than tweaking one that spends a fiver.
9. Check for Suspicious Click Patterns
This is one that most audit guides skip, but it's worth five minutes of your time — especially if you've noticed any of the following:
- Unusual spikes in clicks that don't correspond with any campaign changes or seasonal trends
- High click-through rates paired with zero conversions — real users convert at some rate; if a campaign suddenly shows sky-high CTR with nothing to show for it, something's off
- Rapid budget depletion — your daily budget exhausting far earlier than usual, particularly if it's concentrated in short bursts
- Repeated clicks from the same geographic areas or IP ranges (visible in your analytics if you track IP-level data)
These patterns can indicate click fraud — competitors, bots, or click farms draining your budget without any genuine intent. Google does have built-in invalid click detection, but it doesn't catch everything, particularly more sophisticated attacks.
If you spot anything suspicious, it's worth investigating further. Tools exist that monitor your traffic in real time and automatically block fraudulent sources before they chew through your budget.
10. Review Performance Trends Over Time
Finally, zoom out again. Look at the last 3, 6, and 12 months of data and track the direction of your key metrics:
- Cost per conversion — is it trending up? That might signal increased competition, audience fatigue, or degrading ad relevance.
- Conversion rate — a declining conversion rate with stable traffic often points to landing page issues or a shift in search intent.
- Impression share — are you losing ground to competitors?
- Click-through rate — a dropping CTR can mean your ads are going stale or competitors are writing better copy.
- Average CPC — rising CPCs across the board might reflect market trends, but sharp spikes in specific campaigns warrant investigation.
Plot these on a graph if you can. Trends are far easier to spot visually than in a table of numbers. Look for inflection points — moments where performance shifted — and try to correlate them with changes you made (or didn't make).
Pulling It All Together
An audit isn't a one-off exercise. The best-run Google Ads accounts build this into a regular rhythm — a light check monthly, a deeper dive quarterly. The goal isn't perfection; it's making sure your money is working as hard as it should be.
Start with conversion tracking (because nothing else matters if that's broken), then work through the rest in whatever order feels most urgent. Even fixing two or three issues from this list can meaningfully shift your return on ad spend.
If step 9 raised any red flags, ClickClickBlock monitors your Google Ads traffic in real time and automatically blocks fraudulent clicks before they waste your budget. It takes about two minutes to set up — worth a look if you suspect your campaigns aren't getting a fair crack.
