Case Study: Improving Google Ads ROI Through Better Attribution
Case Study
Google Ads
Front-end Google Ads data can show clicks and conversions, but it does not always show which campaigns are truly driving revenue. This case study explains how Magnetic North helped a regional commercial security provider use attribution data to better understand campaign ROI.
Overview
A well-established commercial security and access solutions company hired Magnetic North to build, manage, and optimize its Google Ads strategy across multiple service lines.
After MagNorth built out and optimized the ad campaigns over months of collecting data and tweaking settings, the campaigns were producing strong front-end results, including consistent lead volume and efficient cost per conversion. But as the account matured, Magnetic North saw an opportunity to go beyond the standard Google Ads dashboard and better understand which campaigns were creating the strongest business return.
The security provider client provides a range of services, including locksmith solutions, commercial door and frame work, access control systems, and automatic door operator installation. Because each service line carries a different level of demand, project value, and sales complexity, basic conversion reporting could only tell part of the story.
To make better decisions, Magnetic North worked with the client to establish a deeper attribution process that connected campaign activity to quoted opportunities, closed-won revenue, and actual business growth. The goal was not simply to generate more leads. The goal was to understand which campaigns were producing the most valuable opportunities and use that insight to guide smarter ad spend.
The Objective
The objective was to improve how Google Ads performance was evaluated by connecting paid search campaigns to real business outcomes.
Rather than judging campaigns only by clicks, conversions, and cost per conversion, Magnetic North worked with the company to better understand which campaigns were generating the most valuable opportunities and the strongest return on investment.
The Challenge
The company had multiple Google Ads campaigns running across several service lines. On the surface, the campaigns appeared to be performing well. They were generating a strong number of clicks and conversions, and some campaigns showed a very low cost per conversion.
However, as the account matured, it became harder to scale the campaigns based only on front-end Google Ads data. The reporting showed which campaigns were producing the most conversions, but it did not clearly show whether those conversions were becoming qualified opportunities, quoted jobs, or closed-won revenue, especially due to the long sales cycle for the company, which sometimes lasted 3-6+ months.
This created a common but important problem: the campaign with the highest conversion volume appeared to be the strongest performer, while a lower-volume campaign seemed less significant in the platform data.
If budget decisions were made using only cost per conversion and lead volume, the company risked shifting spend toward campaigns that looked efficient in Google Ads but did not necessarily produce the best business outcomes and ROI.
The Attribution Gap
A conversion is an important signal, but it is not the same as revenue. A form submission or phone call may represent interest, but it does not automatically mean the lead became a quote, a project, or a profitable customer.
The missing layer was attribution between the marketing source and the final sales outcome. Magnetic North needed a clearer way to connect each campaign to the value of the opportunities it produced after the initial lead came in.
That meant looking beyond what happened inside Google Ads and building a more complete feedback loop between marketing data and sales data.
The Strategy
Magnetic North and the company developed a more detailed monthly attribution process. The company began sharing information about quoted opportunities, including the contact, company, and quoted dollar value associated with each job.
Magnetic North then cross-referenced that information with lead tracking data from tools such as HubSpot, CallRail, and Google Ads. By reviewing names, phone numbers, email addresses, company names, and campaign source data, the team could connect individual quoted opportunities back to the campaigns that generated them.
As the process developed, the attribution work expanded beyond quoted revenue to include closed-won revenue as well. This allowed campaign performance to be evaluated based on both the value of opportunities created and the revenue ultimately won.
This gave the team a much clearer view of which campaigns were producing the most valuable business outcomes, not just the highest number of leads.
What the Data Revealed
Once campaign performance was compared against quoted revenue and closed-won business, the results told a more complete story.
The campaign producing the highest number of conversions on the front end was not always the campaign producing the strongest return at the end of the day. In contrast, one of the lower-volume service-line campaigns generated fewer leads but produced stronger opportunities and a better return relative to the amount spent, and a better ROI.
This was a critical insight. If the team had relied only on front-end Google Ads data, it would have been easy to prioritize the campaign with the most conversions. With deeper attribution in place, Magnetic North could identify where the company’s marketing dollars were creating the most meaningful revenue impact.
The result was a more accurate understanding of lead quality, campaign value, and budget efficiency.
The Results
The improved attribution process gave the company and Magnetic North a more reliable way to evaluate paid search performance. Instead of focusing only on surface-level conversion metrics, campaign decisions could be made with a clearer understanding of quoted revenue, closed-won revenue, and overall ROI.
This created several important benefits:
- Smarter budget allocation based on revenue potential, not just lead volume.
- Better visibility into which service lines generated the strongest opportunities.
- More confidence when testing new campaigns, service areas, and markets.
- Stronger long-term optimization as campaign performance shifted over time.
- A clearer connection between marketing spend and actual business growth.
The process also helped the company avoid overvaluing campaigns that looked strong in the ad platform but did not necessarily produce the same level of return after the lead entered the sales process.
Why Ongoing Attribution Matters
One of the most important takeaways from this work is that attribution is not a one-time project. Campaign performance changes over time. Seasonal demand shifts, competition changes, and customer needs evolve.
A campaign that produces strong ROI for several months may not remain the strongest performer indefinitely. In the same way, a lower-volume campaign may become more valuable as market conditions change.
Because of that, Magnetic North continues to evaluate campaign performance through an ongoing attribution lens. The goal is not to set a budget once and leave it alone. The goal is to keep watching how marketing spend translates into real business value and adjust strategy as the data changes.
Conclusion
For this regional commercial security provider, stronger attribution turned Google Ads reporting into a more complete view of marketing performance.
By connecting campaigns to quoted opportunities and closed-won revenue, Magnetic North helped the company better understand which campaigns were truly producing value. This made it possible to make smarter budget decisions, identify higher-quality lead sources, and continue improving ROI over time.
For businesses with multiple service lines, high-value projects, or longer sales cycles, front-end conversion data is only part of the story. The deeper insight comes from understanding what happens after the conversion.
That is where attribution becomes essential.
When businesses understand where revenue is actually coming from, they can make better decisions about where their marketing dollars should go.
