Let’s skip the boring, overused Google Ads metrics you’ve seen everywhere. We’re getting into the real deal—the metrics that’ll make your clients take notice.

We understand which metrics are most valuable to showcase to your clients because we have the data to back it up. We rely on insights from thousands of real-world metrics agencies use to drive success.

What do most agencies track for their Google Ads clients?

Top 6 Most Important Metrics (Based on Data)

However, we did some digging and tried to get into the core of what really matters to your clients.

And the results?

Top 6 Most Important Metrics (According to the Article)

We will review these metrics in this article. First, we will discuss each metric and why it is really important, then explain the difference.

You know the drill. You’re managing multiple Google Ads accounts, working with tight budgets, and your clients are eager for results.

We’re about to turn those Google Ads metrics into your secret weapon.

Essential Google Ads Metrics That Drive Ad Performance

As a marketing agency, focusing on the right metrics is crucial for optimizing Google Ads campaigns. 

We’ve identified seven key metrics that provide a comprehensive view of campaign performance, from initial user engagement to final return on investment. 

Let’s explore why these metrics matter and how to use them effectively.

MetricDescriptionWhy It Matters
CTR (Click-Through Rate)Percentage of people who click your ad after seeing itIndicates ad relevance and appeal to your audience
CPC (Cost Per Click)Average amount you pay for each clickDirectly impacts budget efficiency and ROI
Conversion RatePercentage of clicks that result in desired actionsShows how effectively your ads and landing pages drive results
CPA (Cost Per Acquisition)Average cost to acquire a customerHelps measure the efficiency of your ad spend in generating customers
Quality ScoreGoogle’s rating of ad quality and relevanceAffects ad rank and cost per click
Impression SharePercentage of times your ads are shown out of the total available impressionsIndicates potential reach and missed opportunities
ROAS (Return on Ad Spend)Revenue generated for every dollar spent on adsDirectly measures the profitability of your campaigns

1. Click-Through Rate (CTR) and Its Impact on Ad Quality

CTR is the ratio of clicks to impressions, expressed as a percentage. It measures how often people who see your ad end up clicking it. CTR is essential because it indicates the relevance and appeal of your ads to your target audience. It directly influences Quality Score and can affect your CPC and ad position. A high CTR indicates that your ad resonates with your target audience.

Sure, you know CTR. But are you really using it to its full potential? Let’s break it down:

  • Look at CTR by ad position. Is the top spot always king, or are you wasting money on position one when position three converts better?
  • Compare mobile vs. desktop CTR. If your mobile CTR sucks, you’re missing out on a huge chunk of traffic. Time to optimize those mobile ads and landing pages.
  • Analyze time of day and day of week CTR. Spot those golden hours when your ads are irresistible. Use this to fine-tune your ad scheduling and bid adjustments.

What can you do to improve CTR?  Google Ads Specialist Nick Jervis explains:

“Optimizing your ad copy and landing page is one of the most essential aspects. With an overload of multiple client campaigns, advertisers rely on Google AI’s suggestions to improve their ad copy and spend almost no time writing a good landing page. It is an incredibly important part of the process, and if you see people clicking on your ad but not converting – you know where the error lies. You’re paying for those clicks, and if they don’t turn into clients, you need to realign your messaging proposition and make sure your copy is relevant to the keywords you’re targeting. “

Also, try this: Create a CTR heat map by hour and day—it’s your go-to guide for knowing exactly when to ramp up bids in your Google Ads campaigns.

2. Cost Per Click (CPC) and Optimizing Your Ads Budget

CPC is the average amount you pay each time someone clicks on your ad. It’s calculated by dividing the total cost of clicks by the total number of clicks. CPC is crucial for budget management. It determines how many clicks you can get within your budget and affects overall campaign profitability. Keep a close eye on this to manage your budget effectively.

Forget what you’ve heard about always aiming for the lowest CPC. It’s about value, not just cost. Here’s how to level up your CPC game in Google Ads:

  • Calculate your maximum CPC based on conversion rates and customer lifetime value. You might be surprised how much room you have to bid up.
  • Use bid simulators. They’re like a crystal ball for your CPC. See how changes might impact your overall Google Ads performance before you make them.
  • Track CPC trends over time. Sudden spikes could mean increased competition or seasonal effects. Knowledge is power, people.

Word to the wise: Don’t let Google’s automated bidding run wild. Set up alerts for CPC spikes and regularly review your target CPA/ROAS. Trust, but verify in your Google Ads account.

3. Conversion Rate Metrics That Boost Campaign Performance

Conversion Rate is the percentage of ad clicks that result in a desired action, such as a purchase or sign-up. It’s calculated by dividing the number of conversions by the number of total ad clicks. This metric is crucial because it shows how effectively your ads and landing pages turn clicks into desired actions. It’s a key indicator of campaign success and ROI.

We’ve interviewed Sophie Logan, PPC Lead at Beauhurst and brightonSEO speaker and she said this is the first thing she looks for:

In my role, I’m looking at the Conversion Rate so that I can see how well the traffic I am sending to the page finds what they need and submits an inquiry form. A big red flag for me is when a PPC landing page receives a high level of traffic through search terms indicating the relevant interest and intent but fails to convert those visitors once they’re on the page.

Check out her interview here.

Conversion rate optimization is where the magic happens in Google Ads. Here’s how to become a conversion wizard:

  • Implement micro-conversions. Track user intent with actions like add-to-cart or email sign-ups. It’s like breadcrumbs leading to the big conversion.
  • A/B test. Use Google Optimize to test landing pages. Small tweaks can lead to big gains in your Google Ads campaigns.
  • Analyze conversion rates by match type. Are broad match keywords bringing in tire-kickers while exact match closes the deal? Adjust your ad groups accordingly.
  • Improve the landing page experience. Focus on faster load times, clear calls to action, and seamless user experience across devices.

Pro tip: Create a “conversion quality score” by weighing different conversion actions. Not all conversions are created equal in Google Ads, right?

4. Cost Per Acquisition (CPA) for Effective Campaigns

CPA is the average amount you spend on ad clicks or impressions to acquire one customer or conversion. It’s calculated by dividing the total cost of ad clicks or impressions by the number of acquisitions. CPA is essential for understanding the true cost of gaining a customer or lead. It helps determine if your campaigns are profitable and guides budget allocation decisions.

CPA is the metric that keeps your clients up at night. Make it work for you in Google Ads:

  • Set dynamic CPA targets. Product margins change, seasons change, and why should your CPA target stay the same?
  • Use the target CPA simulator. It’s like a “what if” machine for your Google Ads budget. Show clients the potential impact of budget changes.
  • Track CPA by audience segment. Find those golden customers who are worth their weight in gold in your Google Ads campaigns.
  • Relate CPA to customer lifetime value. Suddenly, that higher CPA doesn’t look so bad when you see the long-term value of their Google Ads investment.

5. Quality Score and How It Affects Your Google Ads Account

Quality Score is Google’s 1-10 rating of the quality and relevance of your keywords, ads, and landing pages. It’s used to determine your ad rank and CPC. Quality Score is critical because it affects both your ad rank and CPC. Improving Quality Score can lead to better ad positions at lower costs, improving overall campaign efficiency.

Quality Score impacts everything in Google Ads. Master it, and you’ll rule the Google Ads kingdom:

  • Create a Quality Score dashboard. Track changes over time and spot trends before they become problems in your Google Ads account.
  • Use the “Miner and Mother Lode” technique. Find high-volume, low QS keywords (miners) and create hyper-relevant ads and landing pages for them (mother lode).

Agency pro move: Develop a proprietary “Quality Score Improvement Process” for Google Ads.

6. Impression Share Metrics for Maximizing Ad Visibility

Impression Share is the percentage of impressions your ads receive compared to the total number of impressions your ads were eligible to receive. It’s calculated by dividing actual impressions by total eligible impressions. This metric is important for understanding your market presence and identifying missed opportunities. It helps you gauge how much more potential reach your campaigns have.

Impression share tells you how much of the pie you’re getting in Google Ads. Here’s how to use it:

  • Improve “Search lost IS (rank)” by enhancing ad quality and relevance. It’s like a report card for your ad quality in Google Ads. Low score? Time to step up your game.
  • Address “Search lost IS (budget)” by optimizing budget allocation across campaigns. Show clients where they’re leaving money on the table in their Google Ads campaigns.
  • Use Auction Insights to compare your Impression Share with competitors. Know thy enemy in the Google Ads auction, right?

Food for thought: 100% impression share isn’t always the goal in Google Ads. Find the sweet spot where incremental impressions still drive profitable conversions.

7. Return on Ad Spend (ROAS) and Its Importance

ROAS is a ratio that measures the revenue generated for each dollar spent on advertising. It’s calculated by dividing the revenue attributed to ads by the cost of ads. ROAS is essential as it directly measures campaign profitability. It shows how much revenue you’re generating for every dollar spent on ads, which is crucial for justifying ad spend and optimizing campaigns.

ROAS is king in Google Ads, but it’s not always straightforward. Here’s how to crown yourself ROAS royalty:

  • Implement value-based bidding. Optimize for revenue, not just conversions in Google Ads. After all, it’s the bottom line that really counts.
  • Use data-driven attribution. Get the full picture of the customer journey in Google Ads, not just the last click.
  • Track ROAS by product category. Use this to inform inventory and promotion decisions in your Google Ads campaigns.
  • Segment ROAS by campaign type (e.g., brand vs. non-brand) to set appropriate targets for each. Not all campaigns are created equal, and your ROAS goals should reflect that.

Client wow factor: Create ROAS forecasts based on historical Google Ads data and planned promotions. Show them you’re thinking three steps ahead.

Why These Metrics Matter More Than What Agencies Currently Track

Let’s explore why we’re taking a different approach. With insights from over 2,000 agencies on what they’re tracking, we’re not just following the norm. Here’s what we’ve found:

The Usual Metrics Everyone is Tracking

Many agencies focus on Clicks, Impressions, and Cost (Micros). While these are essential Google Ads metrics, they don’t always tell the full story:

  • Clicks and Impressions: They show how many people saw and clicked your ad, but are those clicks turning into actual revenue? That’s the real question.
  • Cost (Micros): Track spending, but if you’re not aligning it with actual value or return, the budget isn’t being used as effectively as it could be.

Key Metrics for Maximum Impact

Now, let’s focus on the metrics that can truly elevate your campaigns: CTR, CPC, Conversion Rate, CPA, Quality Score, and ROAS. These are the metrics that matter, and here’s why:

  • CTR and Quality Score: These two go hand in hand. A high CTR means strong engagement and a high-quality Score helps you pay less while appearing more often—delivering better results for your budget.
  • CPC and CPA: CPC tells you how much you’re paying for a click, but CPA? That’s the money metric. It reveals the cost of each conversion, which is what your clients care most about.
  • Conversion Rate and ROAS: This is where the rubber meets the road. Conversion Rate shows you how many clicks turn into customers, and ROAS? That’s the “show me the money” metric. It tells you how many bucks you make for every dollar you spend.

Why We’re Taking the Road Less Traveled

We’re not just going with the usual approach; we’re focused on leading with what works best. And here’s why our metrics are the real MVPs:

  • Client-Centric Approach: Your clients aren’t interested in impressions alone; they care about impressions that lead to sales. Our metrics are designed to reflect what matters most—driving real profit.
  • Efficiency and Optimization: With key metrics like CPA and ROAS, you’re not relying on guesswork. You’re making strategic, data-driven decisions to maximize impact.
  • Holistic Campaign View: We’re not just skimming the surface here. Our metrics dive deep, giving you a 360-degree view of your campaign’s performance.

Sure, the CSV crowd is playing it safe with their clicks and impressions. And most likely these metrics were awesome back then.

But now?

But you?

You’re playing to win. By focusing on our power-packed metrics, you’re not just showing your clients that their ads are running – you’re showing them that their ads outperform the competition.

How to Choose the Right KPIs for Your Google Ads Campaigns

Choosing the right metrics is like cooking a great meal—get the ingredients just right, and you’ll impress everyone at the table. Miss the mark, and you risk leaving a bad taste that’s hard to fix.

Why KPIs Matter (And Why Choosing the Wrong Ones Hurts)

Think of KPIs as the GPS for your marketing campaigns. The right KPIs will steer you directly toward increased ROI, while the wrong ones can lead to wasted time, budget, and missed opportunities.

Choose the wrong KPIs, and here’s what you’re risking:

  • Your strategies will be as off-target as a mismatched campaign
  • You’ll waste time chasing metrics that don’t drive real value
  • Your clients will start questioning the return on their investment
  • You’ll miss opportunities that could have positioned you as the expert they rely on

In short, poor KPI selection can turn your Google Ads ship into the Titanic – impressive on the surface but headed straight for an iceberg.

Understand Your Client’s Metrics Inside and Out

First things first: you need to get inside your client’s head. Don’t just guess what they want – ask them directly.

Discovery Questions:

  • “What’s the one metric that would make you pop champagne if it improved?”
  • “If you had to choose between more traffic and higher conversion rates, which would it be?”
  • “What’s your biggest fear when it comes to ad spend?”

Pro Tip: Schedule a goals workshop to really understand what success looks like for your client.

Play Detective with Past Data

Look at what’s worked before. Past performance isn’t guaranteed, but it’s a good place to start.

Data Diving Tips:

  • Use Google Ads’ date comparison feature to spot trends
  • Look for correlations between metrics (e.g., does higher CTR lead to better conversion rates?)
  • Don’t ignore seasonality – what worked in December might bomb in July

Map Out the Customer Journey

Identify the key points in your customer’s journey. This will help you choose metrics that matter at each stage.

Create a visual funnel with your client. Mark each stage with potential metrics. It’s like playing KPI Pictionary.

Match Metrics to Your Mission

Align your KPIs with your campaign goals. A lead gen campaign needs metrics different from those of a remarketing one.

Goal-Metric Matchmaking:

  • Brand Awareness Goal → Impression Share, Reach
  • Lead Generation Goal → Cost Per Lead, Lead Quality Score
  • Sales Goal → ROAS, Conversion Rate

Mix It Up

Use both predictive metrics (like CTR) and results-based ones (like ROAS). It’s like having both a weather forecast and an umbrella.

Metric Mixing Recipe:

  • 2 parts lagging indicators (results)
  • 1 part leading indicators (predictive)
  • A dash of diagnostic metrics

Keep It Lean and Mean

Don’t be a metric hoarder. Focus on 3-5 key metrics that’ll actually move the needle.

  • Use the ICE framework: Score each potential KPI on Impact, Confidence, and Ease of implementation.
  • Implement a scoring system: Rate metrics based on their alignment with business goals and actionability.

Ensure Measurability

All the fancy metrics in the world won’t help if you can’t track them.

  • Audit your tracking capabilities: Make sure you have the necessary tools and integrations in place.
  • Set up proper conversion tracking: Use Google Ads conversion tracking and Google Analytics goals.
  • Consider additional tools: Look into call tracking software or heat mapping tools if needed.

Test, Learn, Repeat

Start with your chosen KPIs, but be ready to pivot. If something’s not working, don’t be afraid to change it.

A/B Testing your KPIs. Run two dashboards side by side – one with your gut-feel KPIs and one with alternatives. May the best metrics win!

There are no one-size-fits-all KPIs to choose from. The metrics you choose vary from business to business. If you’re an e-commerce marketer using Google Ads, your KPIs will vary from those of a B2B company that primarily uses the platform to generate leads. PPC and SEO expert Veronika Holler says:

“Analysis and reporting are the A to Z of successful campaigns. The most important KPI for me is the conversion value – but of course, the KPIs depend on the campaign’s goals. If I have a brand awareness campaign, I look at the impressions and clicks. Ultimately, however, I bring everything together and examine the revenue.” 

As an agency, choose KPIs that not only impress your clients but drive real, measurable results. Remember, the goal isn’t just to report numbers – it’s to use those numbers to continuously improve your campaigns and deliver value to your clients.

Questions to Ask Yourself (Before You Commit to a KPI)

Before you put a ring on that KPI, ask yourself:

Is this KPI right for where we are in the customer journey?

  • Good: Email sign-ups for a top-of-funnel campaign
  • Bad: Purchase value for a brand awareness campaign

Does this KPI actually relate to what we’re trying to do?

  • Good: Conversion Rate for a sales campaign
  • Bad: Impressions for a direct response campaign

Can we measure this thing without a degree in rocket science?

  • Good: CTR (easy to track in Google Ads)
  • Bad: Brand sentiment (requires complex social listening tools)

Will this KPI give us actionable intel, or just look pretty?

  • Good: Cost Per Acquisition (tells you when to adjust bids)
  • Bad: Number of ad variations (doesn’t indicate performance)

Will our client actually care about this metric?

  • Good: ROAS (directly ties to revenue)
  • Bad: Ad relevance score (a component of Quality Score, but may be too granular for some clients)

Dodge These Common KPI Pitfalls

Even the pros sometimes step into KPI quicksand. Here’s how to avoid joining them:

Vanity Metrics: These are the Instagram filters of the ad world. They might make you look good, but do they pay the bills? Spoiler: They don’t.

One-Metric Wonder: Don’t put all your eggs in one metric basket. You need a team of KPIs, not a solo artist.

Context Blindness: Remember, KPIs don’t exist in a vacuum. Always consider the bigger picture when you’re number-crunching.

Set It and Forget It: Your KPIs aren’t a slow cooker. Don’t set them and walk away. Keep checking and adjusting as your campaign evolves.

Funnel Vision: Make sure your KPIs match where you are in the sales funnel. Don’t expect bottom-of-funnel results from your top-of-funnel efforts.

Wrapping Up

CTR to ROAS: We’ve covered the numbers that’ll make your campaigns pop and your clients swoon.

But note that these metrics aren’t just fancy figures to impress your boss (though they’ll do that too). They’re the real tools you need to dominate your ad performance. Track, report and monitor them consistently.

While these are essential metrics, your client will only consider what aligns with their goals. What works for Jim’s Plumbing might bomb for Joan’s Software. Keep testing, keep learning, and keep optimizing.
