For many law firms, phone calls remain the most important channel for acquiring new clients. But do you actually know where your calls are coming from – a Google Ads click, a referral, or perhaps an advertisement in the local weekly newspaper?
This is exactly where call tracking comes in: This technology allows calls to be evaluated using data, campaigns to be made more efficient and the marketing budget to be used in a targeted manner.
This article explains what call tracking is, how it works, and what specific benefits it offers your law firm.
What is call tracking?
Call tracking – also known as incoming call tracking – is a method that allows you to analyze incoming calls: Where did the call come from? Which advertising campaign triggered it? What can be deduced from this for your marketing strategy? The goal is to make the so-called "customer journey" transparent – that is, the path from the first contact to the phone call – and to draw conclusions for better customer acquisition.
Why is call tracking useful for law firms?
Call tracking provides valuable data that allows you to measurably improve your advertising efforts – regardless of whether you advertise regionally, nationwide, or even internationally. The key benefits at a glance:
- Better overview of the ROI
Identify which measures actually lead to calls and client inquiries – and how your budget can be used effectively. - Optimizing your marketing strategy
By assigning calls to specific channels or ads, you can see what works – and what doesn't. - Greater efficiency in everyday law firm work
Call tracking can also improve internal processes, for example when it comes to frequently asked questions or unnecessary calls. - Multichannel tracking
Track inquiries across different channels – whether Google Ads, SEO, social media or print ads.
Which call tracking solutions are right for your law firm?
Before choosing a tool, you should ask yourself some basic questions:
- What exactly would you like to measure? (e.g., number of calls, call duration, mandate requests)
- What are your goals? (Efficiency, ROI, improved accessibility)
- Should other channels such as SEO or email also be included?
- Are simple reports sufficient – or do you need integration into your law firm software?
Tip: Choose a solution that fits your actual needs – not the one with the most features.
Call tracking methods: Overview & comparison
| method | How it works | Advantages | Disadvantages |
| Individual phone numbers | Each advertising campaign receives its own number. | Simple assignment | No detailed analysis by keywords |
| Telephone number pools | Visitors are dynamically assigned a number from a pool. | Tracking down to the keyword level is possible | Prone to errors on subsequent calls |
| Virtual call assistants | AI takes over call answering and forwards calls | Efficient & data-driven | Some callers prefer human contact. |
Individual phone numbers
Ideal for a quick overview: Assign a unique number to your website, flyers, and advertisements, for example. This way, you can see where your calls are coming from – and when they arrive.
Telephone number pools
Each website visitor receives their own temporary phone number. When they call, you can track exactly which page they visited and which keyword they used – ideal for Google Ads and SEO campaigns.
Virtual call assistants
Automated call answering via AI: The virtual assistant asks about the caller's needs and forwards them accordingly – including data analysis to optimize processes and accessibility.
