In the world of law firm marketing, understanding how your campaigns perform is critical to making informed decisions. Two metrics often discussed by marketers are ROI and ROAS. While they both measure effectiveness, they serve different purposes and provide different insights. Knowing how to interpret these numbers can help law firms allocate budgets wisely and achieve measurable results.

What ROI Measures and Why It Matters

Return on Investment, or ROI, is a financial metric that evaluates the overall profitability of an investment. In the context of law firm marketing, ROI helps determine whether the money spent on a campaign generates more revenue than it costs. To calculate ROI, you subtract the cost of the investment from the revenue it generated, then divide that number by the cost of the investment.

For example, if a law firm spends $5,000 on an online ad campaign and gains $15,000 in new client revenue, the ROI would be calculated as follows: ($15,000 – $5,000) ÷ $5,000 = 2, or 200%. This means the firm earned double the money it invested.

ROI is valuable because it gives a clear picture of the bottom line. It accounts for all costs associated with the campaign, including ad spend, personnel, software, and other resources. This comprehensive perspective is essential for law firms, which often operate with tight budgets and need to ensure every dollar contributes to profitability.

What ROAS Measures and Why It Is Useful

Return on Ad Spend, or ROAS, is a metric that focuses specifically on the revenue generated by advertising efforts. Unlike ROI, it does not factor in all operational costs, making it a narrower but more immediate measurement of ad effectiveness.

To calculate ROAS, divide the revenue generated by a campaign by the amount spent on advertising. Using the previous example, if $5,000 was spent on ads and it resulted in $15,000 in revenue, the ROAS would be $15,000 ÷ $5,000 = 3, or 300%. This indicates that every dollar spent on advertising returned three dollars in revenue.

ROAS is particularly useful for digital marketing campaigns where ad spend is easy to track. Platforms like Google Ads or Facebook Ads provide real-time reporting, allowing law firms to monitor which campaigns are performing best. By focusing on ROAS, marketers can quickly identify which ads bring in the most clients and adjust strategies accordingly.

Key Differences Between ROI and ROAS

While ROI and ROAS are related, they are not interchangeable. ROI takes a broader view, incorporating all costs and providing a picture of overall profitability. ROAS, in contrast, is specific to advertising spend and helps identify which campaigns generate revenue efficiently.

For law firms, understanding this distinction is critical. A campaign may have a high ROAS but a low ROI if operational costs are high. For example, a paid search campaign could generate substantial leads, but if the firm spends heavily on follow-up consultations, staff time, and legal paperwork, the overall profit may be modest. Conversely, a campaign with lower ROAS but minimal additional costs could still yield a strong ROI.

How Law Firms Can Use ROI and ROAS Together

The most effective marketing strategies rely on analyzing both ROI and ROAS. ROAS helps law firms identify high-performing campaigns and allocate budgets where they deliver the most revenue. ROI, on the other hand, provides a full picture of profitability, helping firms ensure that investments contribute to sustainable growth.

By tracking both metrics, law firms can make smarter decisions about ad spend, campaign types, and overall marketing strategy. For example, a firm may notice that social media ads generate a high ROAS but low ROI due to additional internal costs. In this case, they could optimize internal processes or shift resources to campaigns that balance both metrics.

Practical Steps to Improve ROI and ROAS

1. Set Clear Goals: Define what success looks like for each campaign. Is the focus on new client acquisition, consultation bookings, or brand awareness? Clear objectives make it easier to measure both ROI and ROAS accurately.

2. Track All Costs: Include all relevant expenses in ROI calculations. This includes advertising, staff time, software tools, and any third-party services. Overlooking hidden costs can give a misleading picture of profitability.

3. Monitor Campaign Performance: Use analytics platforms to track ad performance in real time. Identify which ads or keywords generate the highest ROAS and adjust campaigns accordingly.

4. Optimize Client Acquisition Processes: Reducing internal costs or streamlining intake procedures can improve ROI without increasing ad spend. Efficiency in handling leads and clients directly affects profitability.

5. Test and Refine: A/B testing ad creatives, targeting options, and landing pages can improve both ROAS and ROI. Small adjustments often lead to significant improvements in campaign performance.

Common Mistakes to Avoid

One common mistake is focusing solely on ROAS without considering ROI. High revenue from ads may seem promising, but if the firm’s operational costs are high, profitability may be limited. Another pitfall is neglecting to track all expenses or not accounting for intangible costs like staff time and software subscriptions. Both oversights can create an incomplete picture of campaign success.

Law firms also sometimes fail to analyze performance over time. Short-term ROAS may be high, but sustainable ROI requires long-term tracking and continuous optimization. Failing to review trends and adjust campaigns can lead to missed opportunities and wasted budgets.

Making Data-Driven Decisions

The ultimate goal of tracking ROI and ROAS is to make informed, data-driven decisions. Law firms that understand these metrics can allocate marketing budgets effectively, identify profitable campaigns, and maximize client acquisition. Rather than guessing which strategies will succeed, firms can rely on measurable results to guide future campaigns.

Tracking both ROI and ROAS also allows law firms to set realistic expectations. Understanding the full costs and revenue potential of campaigns ensures that investments are aligned with overall business goals. By combining careful analysis with strategic planning, law firms can build marketing programs that are both efficient and profitable.

Conclusion 

Measuring ROI and ROAS is essential for law firms that want to grow while maintaining profitability. Each metric provides unique insights that, when used together, allow firms to make strategic marketing decisions and maximize the return on every dollar spent. By monitoring campaigns, optimizing processes, and analyzing data carefully, law firms can improve both client acquisition and overall revenue.
