Unlock Marketing ROI: Google Ads & Looker Studio

Want to prove your marketing efforts are actually working? That’s where marketing analytics comes in. It’s the process of measuring and analyzing the performance of your marketing campaigns. But where do you even begin? Are you ready to transform your data into actionable insights and boost your ROI?

Step 1: Connecting Google Ads to Looker Studio

Looker Studio (formerly Google Data Studio) is a free data visualization tool that’s fantastic for creating reports. And the best part? It integrates seamlessly with Google Ads.

Creating a New Report

1. Open Looker Studio.
2. Click the “Create” button in the top left corner.
3. Select “Report.”

Expected Outcome: A new, blank report opens, prompting you to connect a data source.

Connecting to Google Ads

1. In the “Add data to report” panel, search for “Google Ads.”
2. Select your Google Ads account.
3. Grant Looker Studio the necessary permissions to access your Google Ads data.
4. Click “Add to Report.”

Pro Tip: Make sure you’re logged into the Google account associated with your Google Ads account to avoid permission issues.

Common Mistake: Forgetting to grant Looker Studio permissions. If you skip this step, you won’t be able to access your data.

Expected Outcome: Your Google Ads data is now connected to Looker Studio, and you’ll see a default table populated with some of your campaign data.

Step 2: Setting Up Conversion Tracking in Google Ads

Conversion tracking is the bedrock of effective marketing analytics. Without it, you’re flying blind. Considering the importance of data, are data-driven insights winning in your marketing strategy?

Defining Conversion Actions

1. In Google Ads Manager, navigate to “Tools & Settings” in the top menu.
2. Under “Measurement,” select “Conversions.”
3. Click the blue “+” button to create a new conversion action.
4. Choose the type of conversion you want to track. Common options include:
   • Website actions (e.g., form submissions, button clicks)
   • Phone calls
   • App installs
   • Imported conversions (e.g., offline sales)

Pro Tip: If you’re tracking form submissions, use the “Page load” option and specify the “thank you” page URL as the trigger. This is far more accurate than relying on button clicks alone.

Tracking Form Submissions

1. Select “Website” as the conversion source.
2. Enter your website domain.
3. Google Ads will scan your website. You can either let Google Ads automatically set up conversion tracking or manually add a tag. For more control, I recommend manual setup.
4. Select “Manually add conversion actions using code.”
5. Choose “Page load” as the trigger.
6. Enter the URL of your “thank you” page.
7. Assign a value to the conversion (optional, but recommended if you can estimate the value of a lead).
8. Set the “Count” option to “One” if you only want to count one conversion per ad click, even if the user submits multiple forms. Set it to “Every” if you want to count every submission.
9. Click “Create and Continue.”
10. Install the provided global site tag and event snippet on your website. (This usually involves pasting code into your website’s header or using a tag management system like Google Tag Manager.)

Expected Outcome: Form submissions on your website are now tracked as conversions in Google Ads.

Tracking Phone Calls

1. Back in the “New Conversion Action” setup, select “Phone calls.”
2. Choose whether to track calls from ads using Google forwarding numbers or calls to a phone number on your website.
3. If using Google forwarding numbers, select the call length threshold (e.g., 60 seconds) to qualify as a conversion.
4. Complete the setup and save the conversion action.

Common Mistake: Setting the call length threshold too low. A 10-second call is unlikely to be a qualified lead.

Expected Outcome: Phone calls originating from your Google Ads are now tracked as conversions.

Step 3: Building a Marketing Analytics Dashboard in Looker Studio

Now that your data is flowing, it’s time to build a dashboard that provides actionable insights. This is where the real marketing magic happens.

Adding Key Metrics

1. In Looker Studio, click “Add a chart” in the toolbar.
2. Select a chart type. For overall performance, “Scorecard” charts are great for displaying key metrics. For trends over time, use “Time series” charts. For comparing campaign performance, use “Bar charts.”
3. Drag and drop the desired metrics from the “Available Fields” panel to the chart. Essential metrics include:
   • Impressions
   • Clicks
   • Cost
   • Conversions
   • Conversion Rate
   • Cost per Conversion (CPA)
   • Return on Ad Spend (ROAS)

Pro Tip: Use calculated fields to create custom metrics. For example, you can calculate ROAS by dividing total conversion value by total cost.

Filtering and Segmenting Data

1. Select the chart you want to filter.
2. In the “Properties” panel, click “Add a filter.”
3. Create a new filter or select an existing one.
4. Define the filter criteria. For example, you can filter by campaign name, ad group, or device.

Expected Outcome: Your charts now display data based on your specified filters, allowing you to drill down into specific segments of your campaigns.

Creating a Time Series Chart

1. Add a “Time series” chart to your dashboard.
2. Drag “Date” to the “Dimension” field.
3. Drag “Cost” to the “Metric” field.
4. Add a second metric, such as “Conversions,” to the chart.

Expected Outcome: You can now visualize your cost and conversion trends over time.

Adding a Bar Chart for Campaign Comparison

1. Add a “Bar chart” to your dashboard.
2. Drag “Campaign” to the “Dimension” field.
3. Drag “Cost per Conversion” (CPA) to the “Metric” field.
4. Sort the chart by CPA to quickly identify the most and least efficient campaigns.

Case Study: Last quarter, I used this exact method to analyze a client’s Google Ads performance. We were running three campaigns targeting different demographics in the Atlanta metro area. The initial dashboard showed a high overall CPA. However, after creating a campaign comparison chart in Looker Studio, it became clear that one campaign, targeting young professionals near Midtown, had a significantly higher CPA than the others. We paused that campaign and reallocated the budget to the better-performing campaigns, resulting in a 25% reduction in overall CPA within a month.

Step 4: Analyzing and Acting on Your Data

Building the dashboard is only half the battle. You need to regularly review the data and make adjustments to your campaigns based on what you find. Here’s what nobody tells you: data paralysis is real. Don’t get bogged down in every single metric. Focus on the ones that directly impact your business goals.

Identifying Underperforming Campaigns

Look for campaigns with high CPA, low conversion rates, or declining ROAS. Consider pausing or restructuring these campaigns. It’s also worth revisiting your content strategy to ensure alignment.

Optimizing Ad Copy and Targeting

Analyze the performance of your ads and keywords. Are certain ad copies driving more clicks and conversions? Are you targeting the right audience?

Adjusting Bids

Use the data to inform your bidding strategy. Increase bids on keywords and placements that are performing well, and decrease bids on those that aren’t. For continued success, consider how AI marketing can boost your leads.

I once had a client who was convinced that broad match keywords were the way to go. But after analyzing their search term report, we discovered that a significant portion of their budget was being wasted on irrelevant searches. Switching to phrase match and exact match keywords drastically improved their conversion rate.

By following these steps, you can harness the power of marketing analytics to improve your Google Ads performance and drive better results for your business. The key is to be consistent, data-driven, and always willing to experiment. If you’re making mistakes, learn from demand gen fails.

Don’t let your marketing budget be a guessing game. Start implementing these marketing analytics techniques today to gain control of your campaigns and drive meaningful results. Begin by connecting Google Ads to Looker Studio and setting up conversion tracking—you’ll be amazed at the insights you uncover.
