Let’s be honest — if you’re not tracking which marketing channels drive results for your law firm, you’re essentially throwing darts in the dark. Many legal marketers struggle to measure the effectiveness of their digital efforts, leaving valuable insights on the table and wasting budget on underperforming tactics.
Enter UTM parameters: the unsung heroes of digital marketing analytics that can transform how you understand your audience’s journey to your website. These simple text codes added to your URLs provide crystal-clear insights into which channels, campaigns, and content actually drive engagement and conversions.
What Are UTM Parameters?
UTM (Urchin Tracking Module) parameters are short text codes appended to URLs that help you track the performance of your digital marketing campaigns. They’re named after Urchin Software, the analytics platform Google acquired before launching Google Analytics.
Many legal marketers assume that Google Analytics alone provides sufficient tracking information. However, without UTM parameters, GA often misclassifies traffic sources or lumps them together as “direct traffic” — leaving you with incomplete data about what’s actually working.
The five standard UTM parameters each serve a specific tracking purpose:
- utm_source: Identifies where traffic originates (e.g., LinkedIn, newsletter, legal-directory)
- utm_medium: Specifies the marketing medium (e.g., email, cpc, social)
- utm_campaign: Tracks specific marketing campaigns (e.g., “2024-spring-webinar” or “tax-law-guide”)
- utm_term: Used primarily for paid search campaigns to track specific keywords
- utm_content: Differentiates variations of the same link (e.g., “header-button” vs “footer-link”)
Here’s how a typical UTM-tagged URL might look:

Why Law Firms and Legal Marketers Need UTM Parameters
Why do law firms need to start using UTM parameters? Because they provide the evidence you need to justify your strategies and budget allocation, such as:
- Attribution Clarity: Without UTMs, up to 60% of your traffic might be misclassified. That LinkedIn post your marketing team spent hours crafting? It might show up as “direct traffic” without proper tracking, making your social media efforts appear less effective than they truly are.
- Better ROI Measurement: Law firms investing in multiple marketing channels need to know which ones generate qualified leads. UTM parameters connect the dots between marketing activities and business outcomes, helping you understand which channels not only drive traffic but convert visitors into clients.
- Optimized Budget Allocation: When you discover that your email newsletters generate three times more case inquiries than your paid LinkedIn campaigns, you can make data-driven decisions about where to focus your resources.
- A/B Testing Content Effectiveness: Testing different headlines or calls-to-action? UTM parameters help you track which variations perform better, allowing you to refine your messaging for maximum impact.
- Email & Social Media Tracking: Particularly relevant for law firms, UTM parameters can track which specific links in your newsletters or social media posts drive the most engagement — essential for understanding what content resonates with your audience.
How to Create UTM Parameters (Without Overcomplicating It)
Creating UTM parameters doesn’t require technical knowledge. Follow these five steps to implement them effectively:
Step 1: Download LISI’s Free UTM Builder
Our free Attribution Tracking Builder makes creating UTM parameters straightforward. Simply fill in the fields, and it generates your tagged URL.
Step 2: Be Consistent with Naming Conventions
Consistency is crucial for accurate tracking. Establish clear naming conventions:
- Use lowercase letters throughout
- Use hyphens instead of spaces or underscores
- Be specific but concise
- Document your conventions for team reference
For example, if you’re promoting a webinar on estate planning, your UTM parameters might look like this:
utm_source=linkedin
utm_medium=organic-social
utm_campaign=estate-planning-webinar-2024
Step 3: Shorten URLs Using Bitly or a Custom Shortener
Long UTM-tagged URLs can look unwieldy, especially on social media. URL shorteners like Bitly maintain your tracking while creating cleaner links for sharing. Some social scheduling tools like Hootsuite might automatically shorten your links for you – just be sure they don’t strip any UTM tags in the process!
Step 4: Test Your UTM Links Before Deploying
Always test your UTM links before including them in campaigns. Click through and check your analytics platform to ensure data is being captured correctly.
Step 5: Track Results in Google Analytics (GA4) and/or Your CRM
In GA4, find your UTM data under Reports > Acquisition > Traffic acquisition. Many CRMs also capture UTM parameters, allowing you to track not just visits but conversions tied to specific marketing efforts.
Real-World Example: Law Firm Event Promotion
Let’s say your firm is hosting a webinar on “Legal Implications of AI in Healthcare.” You’re promoting it across multiple channels and want to understand which drives the most registrations.
LinkedIn Ad:

Email Newsletter:
https://www.yourfirm.com/ai-healthcare-webinar?utm_source=newsletter&utm_medium=email&utm_campaign=ai-healthcare-webinar-2024
Google Ads PPC:
https://www.yourfirm.com/ai-healthcare-webinar?utm_source=google&utm_medium=cpc&utm_campaign=ai-healthcare-webinar-2024&utm_term=healthcare-compliance
After the campaign, your analytics revealed that while LinkedIn drove more clicks, email newsletter recipients had a 40% higher registration rate and better attendance. This insight might lead you to focus on nurturing your email list for future events rather than increasing your LinkedIn ad spend.
Common Mistakes to Avoid
Even savvy marketers make these common UTM tracking errors:
- Not Using UTMs at All: This is the biggest missed opportunity. Without UTMs, you’re making decisions based on incomplete data.
- Inconsistent Naming Conventions: Using “Email,” “email,” and “e-mail” as source parameters creates three separate data points for the same channel, fragmenting your results.
- Overcomplicating the Parameters: Keep your parameters intuitive and manageable. You don’t need to track every possible variable.
- Forgetting to Check Analytics: Implementing UTMs without regularly reviewing the data defeats their purpose. Schedule monthly reviews of your UTM performance.
- Not Aligning UTM Tracking with CRM Data: The real power comes when you connect website traffic to business outcomes. Ensure your CRM captures UTM data for closed-loop reporting.
Start Tracking, Start Improving
UTM parameters provide the visibility legal marketers need to prove value and optimize performance. They transform vague marketing reports into precise data stories that demonstrate impact and inform strategy.
The good news? You can start small. Begin by adding UTM parameters to your next email campaign or social media post. Analyze the results. Then gradually expand your tracking to cover all your digital marketing channels.
With each campaign, you’ll gather invaluable data about what works for your firm — allowing you to make smarter decisions about where to invest your marketing resources for maximum impact.
