For many small business owners, running Google Ads campaigns can feel like a leap of faith in a black hole — hoping that the money spent will translate into meaningful sales. The key to making informed decisions lies in understanding how much profit your ads are generating and whether increasing your budget will lead to more profitable customers. This process is different depending on your type of business. Calculating budgets may look different for a (like home improvement, HVAC, or cabinetry) vs a recurring revenue model business (like fitness studios or medspas).
SINGLE PURCHASE
For businesses that rely on large, one-time purchases, calculating the profitability of your ad campaigns is relatively straightforward. Start by determining how much profit you’re making from customers acquired through Google Ads. If the profits from these ad-driven sales exceed your ad spend, you have a positive return on investment (ROI). From here, the question becomes: should you spend more on ads? The answer is yes—but incrementally. Increase your budget in small steps and monitor whether the additional spend generates new customers whose profits also exceed the ad cost. Continue this process until you reach a point of diminishing returns, where further budget increases don’t result in acquiring more customers.
LIFE TIME VALUE (LTV)
For recurring revenue businesses like medspas or fitness studios, the calculation shifts from a single transaction to a customer’s lifetime value (LTV). A medspa customer, for example, might spend a few hundred dollars on an initial treatment but could continue returning for years. By analyzing your existing customer base, you can estimate their lifetime value, which for medspas often ranges from $2,000 to $5,000. This lifetime value acts as your guide, much like the initial purchase price for one-time purchase businesses, helping you determine whether your ad spend is yielding a profitable ROI.
MEASURE THE THANK-YOU
Regardless of your business type, the foundation of success lies in accurate measurement. The most reliable way to track sales from your Google Ads campaigns is to use a Thank-You-For-Your-Purchase page. This page, equipped with tags for each campaign and ad set, allows you to track conversions directly and assess the performance of your ads in real-time. With this data, you can continuously optimize your campaigns, tweak ad copy and targeting, and identify the spending levels that maximize profitability.
THE DETAILS
To measure traffic from multiple campaigns or ad sets using a single thank-you page, you can leverage URL parameters or Google Ads auto-tagging to differentiate the sources of traffic. Each campaign or ad set can have unique tracking parameters added to the landing page URL, such as "?campaign=summer-sale or ?adset=retargeting". These parameters are carried through the customer’s journey, including to the thank-you page. By configuring your Google Ads conversion tracking tags or using Google Tag Manager (GTM), you can set up triggers that capture these parameters and attribute the conversion to the correct campaign or ad set. Alternatively, enabling auto-tagging in Google Ads appends the gclid parameter to URLs, allowing Google Ads and linked analytics tools like Google Analytics to automatically track which ad and campaign drove the conversion. This ensures that all purchases tracked through the thank-you page are correctly attributed, giving you granular insights into which campaigns are performing best
EXPANDING YOUR ADVERTISING STRATEGY
Most businesses start by advertising their main product or service. Once you've optimized your Google Ad spend in this initial area—maximizing customer acquisition at an acceptable ROI—you can begin to explore additional opportunities. Experiment with new campaigns targeting other parts of your business, such as different products, services, or target audiences. Start small and apply the same data-driven approach you've already used successfully. This strategy ensures that every dollar you spend on ads continues to work as hard as possible to grow your business profitably.
In addition, consider experimenting with promotions by creating specific offers, ads, and landing pages. This can further drive profits around a new service, special events, or holiday specials. Tailored promotions not only attract new customers but also re-engage existing ones, providing fresh incentives to choose your business over competitors. By continuously testing and optimizing these new campaigns, you can uncover additional avenues for growth while maintaining a strong return on your advertising investment.
Optimizing your Google Ads spend is key to driving profitable growth for your business. By leveraging thank-you pages for precise conversion tracking, analyzing ROI, and applying a data-driven approach, you can ensure that every dollar invested in advertising works effectively. Once you've successfully maximized your ad spend in one area, the opportunities for expansion—whether through new products, target audiences, or promotions—are limitless.
