What is QR Code tracking? A beginner’s guide to how it works

QR Codes are on almost everything now; from product labels, menus, packaging, to posters, and even email signatures. In fact, a 22% increase in usage of QR codes is expected across different regions by 2025.

But creating and placing a QR Code is just half the job. 

What happens after someone scans it? 

Did it lead to a sale, a website visit, or just… nothing?

That’s where QR Code tracking comes in. It helps you answer one big question: is this working?

In this guide, we’ll explain how QR Code tracking works, how to use it effectively, and why Replug is one of the best tools to manage your QR codes.

What is QR Code tracking?

QR Code tracking is the ability to analyze what happens after someone scans your code. It lets you collect data like how many times it’s been scanned, where those scans happened, when they happened, and what device was used.

Whether you’re running a marketing campaign, linking to a product manual, promoting an app, or sharing a digital menu; tracking helps you understand how people are interacting with your QR Codes. 

Why QR Code tracking matters in modern marketing

Marketing today is all about data. You want to know what’s working, what’s not, and where your audience is actually engaging. With QR Code tracking, you get exactly that.

How Dunkin’ Donuts brewed up big wins with QR Code tracking

Dunkin’ Donuts, the popular coffee and donuts brand, launched a massive giveaway campaign using custom QR Codes printed on specially marked coffee cups. Customers could scan the code to visit the website, fill out a quick entry form, and enter to win prizes like $1,000 cash, free coffee for a year, DD cards, and daily rewards.

But this wasn’t just a fun promo, it was a smart marketing move powered by QR Code tracking. Dunkin’ could see how many people scanned the codes, where the scans were happening, and which stores were generating the most engagement. This gave them valuable insights into customer behavior and campaign performance, helping them refine their strategy on the fly. The results? Higher sales, stronger brand engagement, and more loyal DD Perks members.

And that’s just scratching the surface. With trackable QR Codes, brands can also:

• Promote their app and increase downloads
• Grow their social media following
• Redirect customers to limited-time discounts
• Educate buyers with videos, tutorials, or product info
• Add QR codes to displays or tags for product details, reviews, or augmented reality experiences
• Analyze QR Code usage to uncover audience behavior
• Use QR Code UTM parameters to track post-scan actions
• Adjust campaigns in real-time based on scan data

And it gets better. With QR Code customization, you can design codes that match your brand, logo, colors, style, without sacrificing trackability. So whether you’re placing a QR Code on your website, a product label, or a flyer; you’re not just adding a shortcut, you’re adding a data touchpoint.

In short: Scans are good. But knowing what happens after the scan? That’s great marketing.

Static vs. Dynamic QR Codes 

Not all QR Codes work the same way, especially when it comes to tracking. If you’re looking to monitor scans, gather data, or update your links without reprinting, it’s important to understand the difference between static and dynamic QR Codes. 

Here’s a quick breakdown to help you choose the right type for your needs:

Feature	Static QR Codes	Dynamic QR Codes
Trackable	❌ Not trackable	✅ Fully trackable (scans, location, device, time)
Editable after creation	❌ No	✅ Yes, you can change the destination URL anytime
Best for	Simple, one-time use (e.g. contact info, menus)	Marketing campaigns, app promotions, product packaging
QR Code analytics support	❌ None	✅ Supports full QR Code analytics
Scan data insights	❌ Not available	✅ Real-time scan data (location, device, timing, etc.)
Includes UTM parameters	✅ But hard-coded	✅ Easily add and update UTM parameters

Why QR code tracking is important

You’re not just creating QR codes for the sake of it. You’re creating them to drive action; visits, signups, installs, purchases. Tracking tells you if that’s actually happening.

Let’s break down the benefits of QR Code tracking:

1. Real-time insights: No need to wait until your campaign ends. With QR code tracking, you can watch scans happen as they come in. That means if something’s off, you can pivot fast.
2. Data-driven marketing: Guessing is expensive. QR Code analytics give you exact numbers, such as: how many people scanned, from where, using what device, and when. This helps you make better decisions, faster.
3. Tracking offline to online engagement: You can track traffic from QR codes placed on flyers, packaging, posters, or business cards and connect your offline materials to real online activity.
4. Track scan behavior by time, location, and device: Want to know if people scan more at night? Or if users in a certain city are more active? QR code tracking answers that. You’ll know where a code has been scanned and on what OS, so you can tailor future campaigns accordingly.
5. Improve campaign performance: If one version of a QR code ad is doing better than another, tracking lets you spot that early. Double down on what works and fix what doesn’t.
6. Enhance ROI: You’re already spending time and resources. Trackable QR codes prove whether you’re getting a return on investment. By analyzing QR Code usage and scan behavior, you’re in a better position to justify your campaign spend.
7. Optimize user experience: Maybe your iOS users are bouncing. Or people scanning from certain cities aren’t converting. QR code tracking gives you the clues to tweak landing pages, content, and CTAs so users have a smoother journey.

And with tools like Replug, all of this becomes seamless. You get dynamic, editable, fully trackable QR Codes along with a complete dashboard that breaks down scan data in real-time; no complicated setup, no extra plugins.

Key QR code tracking metrics to know 

QR codes have become a go-to tool for connecting offline and online experiences, but their real power lies in what you can track. From location and device type to referral sources and total scans, the right tracking can give you a clear view of how your campaigns are performing.

Here’s an example of a QR code created using Replug:

From Replug’s QR code dashboard, you can easily track the following metrics:

1. Total QR scans

See how many times your QR code has been scanned. This is helpful for measuring reach.

2. Total Clicks

Counts every time your link is clicked, including multiple clicks from the same user.

3. Unique Clicks

Tracks individual users. If someone scans your code five times, it still counts as one unique click.

4. Location (country, city, and region)

Track where a code has been scanned to fine-tune your geotargeting strategies.

5. Device/Operating system

Knowing if users scan via Android, Windows, or iOS helps you optimize the landing page or app store experience.

6. Browser

Track which browser was used to open the QR code link to ensure compatibility and optimize performance.

7. Referral

Track where scans come from (e.g. WhatsApp, Instagram) to spot your top-performing channels.

8. Day and month

Track engagement trends by day and month to figure out when people are most active.

In Replug, all of these metrics are displayed inside a dedicated QR code analytics dashboard; fully filterable and exportable.

What is the best way to track QR Code scans?

The best way is to use an advanced dynamic QR code generator or a link management tool with built-in analytics. Static codes don’t offer tracking, but dynamic ones let you monitor scans by location, device, browser, and referral source.

Replug does all this and more. You can edit links anytime and view real-time insights from one clean dashboard.

Best practices for QR code tracking

1. Nail the design and placement

• Make it easy to scan
• Use a call-to-action (e.g., “Scan for 20% off”)
• Don’t hide it in a corner or put it too low

2. Route traffic smartly with one QR code

With Replug’s link rotator, you can send different users to different URLs, all from a single QR code. Set up routing rules based on device type, location, time, or traffic split. It’s ideal for running localized campaigns, showing platform-specific pages, or simply personalizing the experience without ever reprinting your code.

3. A/B test up to 10 URLs behind your QR code

Not sure which landing page will perform best? With Replug, you can A/B test up to 10 different URLs linked to your QR code. Rotate between variations and let the scan data reveal which headline, CTA, or offer drives the most conversions.

4. Retarget every QR code scan

Don’t let your traffic go cold. Replug lets you add retargeting pixels to the links behind your QR codes. This way you can reduce cart abandonment and add anyone who scans your QR code to your ad audiences. This is perfect for staying top-of-mind across Facebook, Google, and other platforms.

5. Stick with dynamic QR codes

Static codes are a one-and-done deal. But with Replug’s dynamic QR codes, you can update destinations anytime, and track real-time QR code analytics.

Avoid common mistakes

• Linking to non-mobile-friendly pages: Most scans happen on smartphones. If your landing page isn’t mobile-optimized, you’re setting yourself up for high bounce rates. Always test your landing page on different devices.
• Skipping UTM tags: Without UTM parameters, you lose the ability to track traffic accurately. Make it a habit to tag every QR code link. Tools like Replug make this easier with their UTM parameter builder.
• Ignoring scan behavior: Pay attention to when, where, and how people are scanning your QR codes. This helps you fine-tune campaigns for better performance. Look for platforms that offer detailed analytics to help spot trends.
• Using low-quality or blurry codes: Poor-quality or blurry QR codes can fail to scan, especially when printed. Replug allows you to download your QR code in JPG, PNG, SVG, and WEBP; all in high quality.
• Forgetting to test before launch: Test your QR code on multiple devices and camera apps to ensure it works under real-world conditions. 
• Over-designing your QR code: It’s tempting to brand your QR code with colors and logos, but don’t compromise readability. Stick to high-contrast colors and make sure there’s enough white space around the code.
• Sending everyone to the same page: Different users may respond better to different content. With Replug, you can use traffic routing (link rotation) to send users to different URLs based on device, location, or time.
