📞What is (Dynamic) Call Tracking?

Call Tracking is what allows you to track the marketing activities that drive calls to your business.

Dynamic Call Tracking is the display of unique phone numbers to your website visitors based on their referral source. Dynamic call tracking uses a technology known as Dynamic Number Insertion (DNI).

Whether visitors come from Google Ads, Facebook, organic search, or another channel, a simple script on your website swaps the default phone number with a tracking number in real time, and you get to see exactly which campaigns are driving high-quality phone leads.

⚙️How Dynamic Call Tracking works

Dynamic Number Swapping

The use of Dynamic Call Tracking is a seamless experience for your customers, who interact with the number just like they would with any other number. Meanwhile, you collect powerful data on which channels, ads, and keywords generate the most valuable calls. Here’s how you do it:

Step-by-step process showing how dynamic call tracking works

Step 1: Choose your call tracking preference

Decide how you want to track phone calls by either choosing Channel-Level Tracking, if you want all visitors from the same source to see the same number or, alternatively, opting for Visitor-Level Tracking, if you want each visitor to see a unique number for session-level attribution. More specifically:

  • Channel-Level Tracking: In this setup, DNI dynamically swaps phone numbers based on the marketing source (e.g., Google Ads, Facebook, organic search). ➡ ️ Everyone coming from the same channel sees the same tracking number. This helps you measure which channels are driving the most phone calls.
  • Visitor-Level Tracking: Here, DNI goes a step further. It assigns a unique tracking number to each individual visitor. ➡ ️ Even if two visitors come from the same channel, each one sees a different phone number. This enables granular tracking, allowing you to tie each call back to a specific session or visitor.

Step 2: Acquire Tracking Numbers & connect them to your business

Purchase tracking phone numbers and set them up with your call flow builder to route calls to the right destination (e.g. your sales or support team).

Step 3: Install the DNI script

Install the Dynamic Number Insertion (DNI) script through a JavaScript snippet via Google Tag Manager, a WordPress plugin, or directly to your site’s code.

Step 4: Detect source or session & Insert Dynamic Number

The DNI script automatically identifies the visitor’s source for channel-level tracking or assigns a session-specific ID for visitor-level tracking, and swaps in the appropriate tracking number on the site – either tied to the source or uniquely to the visitor.

Step 5: Call Attribution and Analytics

Once a visitor calls the number shown to them, the system logs the call and attributes it to the correct source or session, allowing you to analyze what’s truly driving phone conversions.

🎉Benefits of Dynamic Call Tracking

DNI is the engine behind dynamic call tracking. It connects marketing efforts to actual phone conversions at the visitor level – providing granular insights into user behavior before, during, and after the call. It also decreases your operating costs, helps improve marketing efforts, and leads to an increase in conversions – and that’s not even everything:

1. Visitor-level attribution

Understand the entire user journey by tying phone calls to specific traffic sources and behaviors.

Unlike static call tracking, dynamic call tracking allows for Visitor-Level Tracking. Visitor-level tracking is suitable for companies that gather and analyze data at the user level, i.e. the visitor’s journey before, during, and after a call.

Types of data you can track with Visitor-Level Tracking:

Call AttributionVisitor DataCall Data
Source (Google PPC, Google Organic, referrals from yelp.com, etc.)Caller IDs and caller namesCall duration
Campaign, ad group, ad attributionNew vs repeat callerTalk minutes
Keywords (for all PPC)Caller location (Country, state, city)Voicemails
Landing pages driving most callsCaller namesRecordings
Referring domainsPage views and visitsDate and time of the call
Custom Click IDs for A/B TestingCaller Journey: Touchpoints before, during, & after calls#️Call tracking number called

2. Budget savings & spend optimization

Know exactly which keywords, ads, or landing pages are driving conversions.

As a result of the above, dynamic call tracking helps you track all your visitors and campaigns without acquiring hundreds of numbers. That’s because DNI recycles idle tracking numbers, reducing the amount of tracking numbers needed. DNI allows you to understand which landing pages are performing better. This enables marketers to focus on the top converting landing pages and further optimize them.

3. Better SEO results

DNI allows you to identify your top-performing landing pages. 

When you know which of your landing pages bring in the most traction, you know where your optimization priorities lie, so you can improve what’s already there and maximize conversions. When you meticulously tend to your best-performing content, you are much more likely to reap the benefits of improved SERP rankings and, hence, visibility.

4. Enhance multichannel marketing strategy

Track users across multiple touchpoints -online and offline- for a complete view of performance.

Dynamic call tracking helps you understand the cross-channel complexity of your customer’s journey. The way DNI works is it assigns unique phone numbers to each of your marketing channels, so you can easily track customer journeys from the first touchpoint all the way to conversion. The data you collect can:

  • Help you understand which channels are driving the most conversions.
  • Show you what improvements you need to make to your multichannel marketing strategy so you can increase customer engagement.
  • Enable you to create a seamless customer experience across every single touchpoint.

Use these insights to deliver a consistent and personalized user experience and increase your customer’s loyalty. Your bottom-line stats will thank you.

5. Global reach with local trust

Use toll-free or region-specific numbers to connect with users across different countries or cities. 

Dynamic Call Tracking not only enhances your local activities, but also helps you target audiences across whole countries. With toll-free numbers, your callers will instantly feel familiar with your country-wide number instead of seeing a prefix that belongs to an area that’s far from them.

6. Improve conversion rates

Get deeper insights that help you refine your campaigns and increase high-value lead conversions. 

DNI collects all the info you need for your marketing strategy so choosing what works better for you, becomes an easy decision to make. By quickly understanding which keywords, pages and audiences are driving calls, you can easily determine which campaigns generate the most leads.
