How do I read Google Ads reports?
You read Google Ads reports by focusing on the metrics that actually indicate whether your campaigns are making money, which is a much shorter list than what Google shows you. The three numbers that matter most are cost per conversion (what you pay per lead), conversion rate (what percentage of clicks become leads), and total conversions (how many leads you got). Everything else is either a diagnostic metric to help you fix problems or a vanity metric that makes you feel good while your budget evaporates.
Google's reporting dashboard throws 50+ columns at you by default, and most advertisers either get overwhelmed or fixate on the wrong numbers. I've seen business owners celebrate a 12% click-through rate while ignoring the fact that zero of those clicks converted into actual customers. Let me walk through every metric that matters, what "good" looks like, and which ones to ignore.
What do impressions, clicks, and CTR mean in Google Ads?
Impressions are the number of times your ad appeared on someone's screen. An impression doesn't mean anyone saw or read your ad, it means Google displayed it. Think of it as how many times your billboard was driven past, not how many people looked at it.
Clicks are the number of times someone clicked your ad and landed on your website or called your phone number. This is when you start paying, Google charges you per click, not per impression.
Click-Through Rate (CTR) is clicks divided by impressions, expressed as a percentage. A 5% CTR means 5 out of every 100 people who saw your ad clicked it. CTR tells you how compelling your ad is relative to the competition.
| CTR Range | What It Means | Action |
|---|---|---|
| Below 2% | Your ads are being ignored. Ad copy is weak or keywords are irrelevant. | Rewrite ad copy, check keyword relevance, review search terms |
| 2-5% | Average for most industries. Acceptable but room to improve. | Test new headlines, add extensions, improve offers |
| 5-10% | Strong performance. Your ads resonate well with searchers. | Maintain and test incrementally |
| Above 10% | Excellent, or your keywords are very branded/navigational. | Verify keywords aren't just branded searches |
Honest caveat about CTR: A high CTR is not always good. If your ad promises "Free Estimates" and attracts price-shoppers who never convert, your CTR is high but your bank account is empty. CTR is a diagnostic tool, not a success metric.
What is CPC and how much should I pay per click?
Cost Per Click (CPC) is what you actually pay each time someone clicks your ad. It's determined by an auction, you set a maximum bid, but you often pay less than your max because Google uses a second-price auction system. Your actual CPC depends on your Quality Score, your bid, and what competitors are bidding.
Here are realistic CPC benchmarks by industry:
| Industry | Average CPC | Low End | High End |
|---|---|---|---|
| Plumber | $25-35 | $18 | $50 |
| HVAC | $28-40 | $20 | $55 |
| Electrician | $20-38 | $15 | $45 |
| Roofer | $30-50 | $22 | $65 |
| Dentist | $15-30 | $10 | $45 |
| Auto Repair | $10-25 | $8 | $35 |
| Lawyer (PI) | $50-200 | $30 | $300+ |
| Lawyer (Family) | $25-60 | $15 | $80 |
| Landscaper | $12-25 | $8 | $35 |
| Pest Control | $15-28 | $10 | $40 |
What's "too much" for a click? It depends entirely on what that click is worth. A $50 click for a plumber seems expensive until you realize the average plumbing job is $350 and 10-15% of clicks convert to leads. That's a $333-500 cost per lead, with a 50%+ close rate giving you a $667-1,000 cost per customer, on a $350+ job. The math works.
A $50 click for a $40 oil change? That doesn't work unless you have an incredible upsell and retention process.
The metric to watch isn't CPC, it's cost per conversion.
What are conversions and conversion rate?
A conversion is any action you've told Google to count as valuable, a phone call, a form submission, a quote request, or a booking. The definition is entirely up to you, and getting this right is the single most important thing in your Google Ads account. If you're tracking the wrong conversions (page views, button clicks that don't submit anything), every other metric becomes meaningless.
Conversion rate is conversions divided by clicks, expressed as a percentage. If 100 people click your ad and 10 fill out your contact form, your conversion rate is 10%.
| Conversion Rate | What It Means | Action |
|---|---|---|
| Below 3% | Your landing page has serious problems, or your keywords attract the wrong audience. | Review search terms for irrelevant traffic. Rebuild landing page with clear CTA. |
| 3-7% | Below average for local services. Fixable with landing page improvements. | A/B test landing pages, simplify forms, add trust signals (reviews, badges). |
| 7-12% | Solid for most local service businesses. | Optimize incrementally. Focus on scaling volume. |
| 12-20% | Excellent. Your keywords and landing pages are well-matched. | Scale budget carefully, maintain quality while growing. |
| Above 20% | Either you've nailed it, or your conversion tracking is counting non-leads. | Verify conversion tracking accuracy. |
The conversion rate trap: I've seen businesses celebrate a 25% conversion rate that turned out to be tracking page views as conversions. Every visitor who loaded the thank-you page by accident counted as a "conversion." Their real conversion rate was 4%. Always verify that your conversions represent actual leads, real form submissions and real phone calls with a minimum duration (30+ seconds to filter out misdials).
What is cost per conversion and what's a good number?
Cost per conversion (also called cost per lead or cost per acquisition/CPA) is your total spend divided by total conversions. If you spent $1,000 and got 20 leads, your cost per conversion is $50. This is the single most important metric in your account because it directly tells you what you're paying for each potential customer.
Here are realistic cost-per-lead benchmarks by industry:
| Industry | Avg. Cost Per Lead | Good | Great | Too High |
|---|---|---|---|---|
| Plumber | $80-150 | Under $100 | Under $60 | Over $200 |
| HVAC | $100-200 | Under $130 | Under $80 | Over $250 |
| Electrician | $80-160 | Under $110 | Under $70 | Over $200 |
| Roofer | $120-250 | Under $150 | Under $100 | Over $300 |
| Dentist | $80-200 | Under $120 | Under $80 | Over $250 |
| Auto Repair | $50-120 | Under $80 | Under $50 | Over $150 |
| Lawyer (PI) | $200-500 | Under $300 | Under $200 | Over $600 |
| Landscaper | $50-120 | Under $80 | Under $50 | Over $150 |
| Pest Control | $40-100 | Under $60 | Under $40 | Over $120 |
How to evaluate your cost per lead: Compare it to your average job value and close rate. If your plumbing leads cost $100 each and you close 50% of them, your cost per customer is $200. If your average job is $350, you're making $150 profit per customer before overhead. That's healthy.
If your cost per lead is above the "Too High" column, something is broken, usually irrelevant search terms, a poor landing page, or targeting that's too broad. Check the VibeAds Benchmark tool to see how your numbers stack up against industry averages.
What is ROAS and how do I calculate it?
Return On Ad Spend (ROAS) is the revenue generated from your ads divided by the amount you spent on ads. A 3x ROAS means you made $3 for every $1 you spent on Google Ads. For local service businesses, ROAS is harder to track than e-commerce because your "sale" happens offline (a plumber fixing a pipe, a dentist doing a cleaning), but it's the ultimate measure of campaign success.
The formula: ROAS = Revenue from ad-sourced customers / Ad spend
Example: You spent $2,000 on Google Ads. You got 25 leads. 12 became customers. They generated $8,400 in revenue. Your ROAS is $8,400 / $2,000 = 4.2x.
For local services, a healthy ROAS ranges from 3x to 10x depending on the industry. Below 2x, you're probably not covering your overhead and cost of labor. Above 5x, you should seriously consider increasing your budget because you're leaving money on the table.
The honest caveat: Most local service businesses can't track ROAS precisely because they don't connect their Google Ads data to their actual job revenue. They know they got 25 leads, but they don't know which 12 became $8,400 in jobs without a CRM that tracks the full journey. If you're not tracking this, at minimum calculate ROAS using your average job value times your estimated close rate. It won't be perfect, but it's better than flying blind.
What is Quality Score and why does it matter?
Quality Score is Google's 1-10 rating of your keyword-ad-landing page combination. A higher Quality Score means Google thinks your ad is relevant to what the searcher wants, which rewards you with lower CPCs and better ad positions. A Quality Score of 7+ means you're paying below-average CPC. A Quality Score of 4 or below means you're paying a premium for every click.
Quality Score has three components:
| Component | Weight | What It Measures | How to Improve |
|---|---|---|---|
| Expected CTR | ~40% | How likely people are to click your ad | Write compelling headlines, use strong offers, include numbers |
| Ad Relevance | ~20% | How closely your ad copy matches the search query | Include the keyword in your headline, write service-specific ads |
| Landing Page Experience | ~40% | How useful your landing page is after the click | Fast load time, mobile-friendly, relevant content, clear CTA |
The CPC impact is real. A keyword with Quality Score 8 can pay 30-50% less per click than the same keyword with Quality Score 5. Over a $3,000/month budget, that's $900-1,500 in savings, or $900-1,500 more clicks for the same spend. Quality Score optimization is free money.
Honest caveat: Don't obsess over getting every keyword to 10. Anything 7+ is solid. Some competitive keywords with high CPCs naturally land at 5-6 regardless of what you do, because everyone's competing hard. Focus your optimization on keywords scoring 4 or below, those are the ones actively costing you extra money.
What is impression share and should I care about it?
Impression share is the percentage of times your ad appeared out of the total times it was eligible to appear. If your impression share is 60%, your ad showed 60% of the times someone searched your keywords, and you missed 40% of potential customers.
There are two reasons you lose impression share:
Lost to budget (your budget ran out before the day ended): This is the most actionable signal in your account. If you're losing 30%+ impression share to budget, it means there are people searching for your services, your ads are eligible, but Google stopped showing them because your daily budget was exhausted. Increase your budget or narrow your targeting.
Lost to rank (your bid or Quality Score wasn't high enough): Your ad was eligible but a competitor outbid you or had a higher Quality Score. Fix this by improving Quality Score (free) or increasing bids (costs money).
| Impression Share | What It Means | Action |
|---|---|---|
| Below 40% | Missing the majority of potential customers | Check if budget-limited. If yes, increase budget or reduce targeting scope. |
| 40-60% | Showing for about half of searches | Normal for competitive markets. Focus on high-value times/locations. |
| 60-80% | Solid coverage | Good position. Optimize for quality over quantity. |
| Above 80% | Dominating your market | You might have room to lower bids slightly without losing much volume. |
For local service businesses, 50-70% impression share is the sweet spot. Below that, you're leaving leads on the table. Above 80%, you might be overpaying because you're bidding against yourself (diminishing returns on marginal impressions).
What is ad strength and does it actually matter?
Ad strength is Google's rating of your Responsive Search Ad (RSA) from "Poor" to "Excellent" based on the variety and relevance of your headlines and descriptions. Google wants you to provide 15 headlines and 4 descriptions so its algorithm can test combinations.
Here's what I'll tell you honestly: ad strength is a vanity metric. Google's own data shows minimal correlation between ad strength and actual performance. I've seen "Poor" rated ads outperform "Excellent" rated ads by 2x because the "Poor" ad had tightly focused, keyword-relevant headlines while the "Excellent" ad had a bunch of filler headlines that diluted the message.
That said, don't ignore it entirely. "Poor" ad strength usually means you haven't provided enough headline/description variations for Google to test effectively. Aim for "Good", it means you have enough variety without padding your ad with irrelevant headlines just to please the rating system.
What to focus on instead: Look at your actual CTR and conversion rate by ad. Those metrics tell you if your ads are working. Ad strength tells you if Google's algorithm is happy, which is a different thing entirely.
Which metrics should I focus on first?
Focus on these five metrics in this order. Everything else is either a drill-down diagnostic or a vanity metric.
1. Conversions (total count), Are you actually getting leads? If this number is zero or very low, nothing else matters. Fix conversion tracking first, then fix your landing page.
2. Cost per conversion, Are those leads affordable? Compare to your industry benchmarks and your own unit economics. If you can't profit at your current cost per lead, you need to fix something before spending more.
3. Conversion rate, Are clicks turning into leads efficiently? Below 5% for local services means your landing page needs work. Above 10% means your system is working.
4. Impression share lost to budget, Are you missing potential customers? If you're profitable (metrics 1-3 are good) but losing 40%+ to budget, you should spend more.
5. Search terms report, Are the right people clicking? This isn't a metric, it's a report, but it's more important than most metrics. Check it weekly. If you see irrelevant search terms triggering your ads, add them as negative keywords immediately.
Metrics to deprioritize: impressions (meaningless without context), CTR (unless it's below 2%), ad strength (vanity metric), optimization score (Google's suggestion to spend more). These are diagnostic tools, not success metrics.
