How to Tell if Your Google Ads Are Actually Working

You’re spending money every day and your agency is sending you reports full of charts. Clicks, impressions, reach. The problem: none of that tells you whether your ads are actually performing. Most people don’t know what to look at — and the people who manage their accounts are often happy to keep it that way.

Here’s what actually matters and what “good” looks like on each metric.

The Short Answer

Five metrics tell the whole story: CTR, conversion rate, CPC, CPL, and Quality Score. Everything else is either derived from these or a distraction. Before you even look at any of them, though, there’s one check that comes first.

Step Zero: Check Pacing First

The single fastest diagnostic on any account — before you look at a single metric — is whether the account is spending what it’s supposed to.

Take the daily budget, multiply by 10. Compare that to actual spend over the last 10 days. Are they the same?

If your daily budget is $100, you should see roughly $1,000 in spend over 10 days. If you’re seeing $250–500 — less than half — the campaign is underspending. That almost always means the account isn’t configured right. Wrong bid strategy, over-restricted match types, ad groups with no real traffic, or a structure that’s fighting itself. A well-built campaign, given enough budget, will spend the budget.

Underspending looks like a minor housekeeping issue. It isn’t. It usually means the machine is broken at a structural level, and the metrics below will also be off.

The Five Metrics That Actually Matter

CTR — How Good Are Your Ads?

Click-through rate tells you whether your ad copy is resonating with the people who see it. If someone searches for your service and your ad doesn’t make them want to click, you’ve got a messaging problem — not a budget problem.

The cross-industry average search CTR is somewhere around 3.5–6%. That’s the average, and the average account is mediocre. Here’s what I’d look for:

If CTR is low, the problem is usually that the ad copy isn’t clearly connected to the keyword. Someone searches “emergency plumber Dallas,” they need to see “Emergency Plumber in Dallas” in the first line. That sounds obvious but most ads don’t do it.

Conversion Rate — How Good Is Your Landing Page?

Once someone clicks, your landing page has to close the deal. Conversion rate (CVR) tells you whether it’s doing that. If your CTR is solid but your conversion rate is low, the traffic is fine — the page is dropping the ball.

The cross-industry average conversion rate on Google Ads is around 3.75%. Again, average is mediocre.

These two metrics together let you triangulate exactly where the problem is. High CTR, low CVR: ads are great, landing page is the issue. Low CTR, decent CVR: fix the ads — the people who do click clearly like what they find. If both are low, you’ve got work to do on both ends.

CPC — Can You Afford to Play?

Cost per click is a read-only number, mostly. CPC is set by the auction — your CPC is approximately what every other advertiser in your space is paying. You can shave it down a bit with a higher Quality Score (more on that below), but you’re not going to dramatically undercut the market. That’s not how the auction works.

What CPC actually tells you: can your business afford to buy traffic at this price? Software custom development at $60/click — that’s just what it costs to play. If your CPL math works at $60/click, great. If it doesn’t, the answer isn’t to “lower CPC” — the answer is to evaluate whether paid search is the right channel for your unit economics.

What CPC can flag as a red flag: if your CPC looks too low — like unusually low for the category — it usually means you’re running display, YouTube, or Performance Max. Those platforms show cheaper clicks because they’re not search. Cheap traffic from people who weren’t looking for you is rarely good traffic.

CPL — Scorekeeping, Not a Lever

Cost per lead is the number everyone obsesses over, and it’s largely out of your control. Your CPL is approximately what your competitors are paying — it’s an efficient auction. You will not get leads at 10% of what the market pays. Anyone who tells you otherwise is either misrepresenting the tracking or running junk traffic.

Here’s the counterintuitive truth most people aren’t ready for: if the market CPL is $100, don’t try to get leads at $10 — try to get them at $200. You’ll get more of them, and they’ll be more qualified. The leads that convert at a higher threshold tend to be the ones worth having. Most people’s instinct is to chase a lower CPL. The game is actually to maximize qualified leads, which usually means bidding up, not down.

CPL is a scorekeeping number. It tells you what the market has decided your leads cost. What you should actually be focused on is what you make off a lead — which is a business question, not an ads question.

Instant red flag: CPL in the single digits, or around $13. That number is almost always broken tracking. If you’re running home services, legal, or B2B and your CPL reads $13, someone’s counting page visits or chatbot interactions as conversions. The real number is almost certainly much higher — and your account decisions are being made on fiction.

Quality Score — The #1 Predictor

I’ve managed 200+ accounts. We took a sample and ran statistics on what correlates with a performant account. Quality Score was the #1 predictor — over everything else. Ahead of budget, ahead of bid strategy, ahead of account age.

Quality Score is a composite of three things Google measures: expected CTR (will people click your ad?), ad relevance (does your ad match the search term?), and landing page experience (what happens after the click?). It’s not a separate thing you optimize — it’s a wrapper over the same three levers you already control: ad copy, keywords, and landing page.

Why it matters beyond the score itself: a higher Quality Score lowers your CPC. Improving Quality Score from 5 to 8 can cut your cost per click by 30–40%. That’s not theoretical — we ran this on an account recently and saw a 20% CPC drop in two weeks. Not typical, but the direction is reliable. QS is the one place where you can meaningfully move your cost structure, as opposed to just accepting the auction rate.

The fastest way to raise a low-QS keyword: tighten your ad groups so every keyword in a group shares the same theme, and write ad copy that speaks directly to that theme. Ad relevance and expected CTR should basically be 10/10 every time — they’re simple to get right. Landing page experience is where most accounts drop the ball, because people spend $5–10k on a nice website that wasn’t built to convert paid traffic, and then wonder why their CVR is 1%.

What Agency Reports Usually Show (and Why It Doesn’t Help)

If your agency sends you monthly reports full of impressions, CPM, impression share, and absolute numbers — total clicks, total conversions, total calls — that’s not a performance report. That’s theater.

The single worst thing in an agency report: absolute numbers with no normalization. Total conversions went up? Great — did you also increase the budget by 3x? Spend $10,000/day and you’ll get a lot of clicks and calls. That doesn’t mean the account is performing well; it means you spent more. What matters is the rate: clicks ÷ impressions (CTR), conversions ÷ clicks (CVR). Percentages and ratios tell you about performance. Absolute numbers tell you about budget.

CPM is irrelevant for search. Impression share sounds important but is mostly a function of budget. Reach, frequency, engagement — those are display metrics that have no bearing on whether your search leads are generating revenue.

If a report can’t tell you your CTR, your CVR, your CPC, and your CPL with a clear “here’s what’s changed and why,” it’s hiding something. Probably just that nothing’s been touched.

Bad/Okay/Good At a Glance

The Pacing Check and the Ratios Together

The PACING check tells you if the structure is broken. The five ratios tell you if the performance is broken. Run both.

If the account is underspending significantly, the performance metrics may look fine (or even great) because you’re only showing for the most obvious, uncontested searches. That can mask structural problems that’ll surface the moment you try to scale.

If the account is spending correctly but CTR is below 5% and CVR is below 5%, you’ve got optimization work to do — ad copy and landing page, in that order.

If CTR is good, CVR is good, QS is above 7, and the account is spending its budget — the account is doing its job. At that point, your focus should shift to whether your business is converting those leads, which is a separate conversation. For a more systematic walk-through of pulling up an account and running these checks, see how to audit your account in 30 minutes. And if you’re seeing any of the red flags above — single-digit CPL, too-low CPC, chronic underspending — most of them show up in the pattern of signs your Google Ads are wasting money.

When to Get Help

If your account is underspending and your agency can’t explain why, that’s not a minor issue — it means the structure is wrong and every metric you’re looking at is suspect.

If CTR is below 5% after the first 90 days, someone isn’t working on the ad copy. If CVR is below 5% after the first 90 days, either the landing page needs work or the traffic is wrong. Both of those should be actively addressed, not just reported on.

The metric I’d stake the most on: Quality Score. If it’s consistently below 5 across your core keywords, that’s almost always fixable with tighter ad groups and a more focused landing page — and fixing it has a direct, measurable effect on your CPC. If no one managing your account is talking about Quality Score, they’re probably not optimizing at the level that produces results. Start there. Then pull the pacing check. If both look wrong, you’re likely looking at a money-wasting account that needs real attention, not another month of reports.

The how long Google Ads take to work timeline is relevant here too — inside the first 90 days, some of these metrics will be rough even in a well-run account. But by month three, CTR and CVR should both be in the good range. If they’re not, it’s a diagnosis problem, not a patience problem.
