Digital signage occupies an unusual position in the marketing toolkit. Unlike a social media post or an email campaign, it doesn't come with a built-in analytics dashboard. There's no open rate, no click-through metric, no algorithm telling you how many people saw your content. What it offers instead is something more nuanced, and in many ways more powerfu, than digital advertising: a physical presence in a space where attention is already directed, influence exerted at precisely the moment a decision is being made.
The challenge is knowing whether that influence is working. This article sets out the practical methods businesses use to measure the effectiveness of digital signage, from the straightforward to the sophisticated, and how to choose the right approach for what you're trying to achieve.
Understanding the Measurement Funnel
Before you can measure effectiveness, you need to know what you're measuring for. Digital signage serves different purposes in different environments - and the right metrics for a window display trying to drive footfall are completely different from those for a touchscreen kiosk capturing event feedback. The most useful framework is a simple funnel: Attention, Engagement, Interaction, and Action. Each stage is measurable in its own right, and not every campaign needs to reach the final stage to be considered successful.
Attention
The first job of any digital display is to be noticed. Motion, brightness, and contrast are the primary drivers; research consistently shows that dynamic content captures attention significantly more effectively than static imagery in the same environment. Before measuring anything else, the baseline question is simply: are people looking at the screen? This can be assessed informally through staff observation, or more rigorously through footfall analytics tools that track where attention is directed within a space.
According to a 2023 Insivia report, viewers retain 95% of a message when they watch it in a video compared to 10% when reading it in text..
Engagement
Attention and engagement are not the same thing. A person can glance at a screen without processing its message; engagement begins when they stop, read, and absorb what's being communicated. Dwell time is the primary proxy for engagement: how long does someone remain in front of the screen, and does the content hold them there? This is measurable through people-counting hardware, video analytics tools, or simply through staff observation in smaller environments. Content that performs well at the attention stage but poorly at the engagement stage usually has a clarity problem: the message isn't landing quickly enough.
Interaction
Interaction is the stage at which measurement becomes concrete. When a user touches a screen, scans a QR code, or submits information, there is a data point - something recorded, something trackable. This is why touchscreen displays and QR code integration are so valuable from a measurement perspective: they convert the passive experience of viewing a screen into an active event that can be logged and analysed. Not every digital signage deployment needs to reach the interaction stage to justify its investment, but those that do provide the clearest ROI picture.
Action
Action is the downstream consequence of successful signage: the sale made, the enquiry submitted, the route taken, the product picked up. It is rarely directly attributable to a single screen in the way a digital ad click is attributable to a specific campaign, which is why many businesses struggle to make the case for digital signage investment. The most effective approach is to measure action as a change from a baseline: sales of a promoted product before and after a display goes live, footfall through a door before and after a window display is installed, average transaction value before and after a self-service upsell screen is added at the till. The screen doesn't need to be the only variable, it needs to be a plausible contributing factor to a measurable change.
When it comes to sales, Google research cited on www.searchenginejournal.com states that 55% of consumers use video in their purchase making decision.
Your marketing team will have better insights into the popularity of a product launch, understanding the key features that excite the potential buyer. Your sales team will have leads to follow, with key questions already answered so they can fine tune their pitch. Warehouse managers and teams will be able to change operations to ensure they hit targets and keep customers happy.
Define Your Goal Before You Measure Anything
The single most common mistake businesses make with digital signage measurement is trying to measure the wrong thing - or measuring everything and drawing no conclusions from any of it.
Before a display goes live, define one primary success metric. For a retail window display, that metric might be footfall increase. For a self-service kiosk, it might be transactions completed without staff intervention. For an internal communications screen, it might be the reduction in "did you see the email?" conversations. For a loyalty sign-up screen at a café counter, it might simply be the number of new registrations per week.
A single clear metric, measured consistently before and after installation, tells you more than a dashboard full of inconclusive data. Additional metrics can be layered in once the primary one is established, but starting with one gives you a clean baseline and a clear story to tell stakeholders.
Setting Expectations
A crucial part of data measurement is to set expectations on the activity to be implemented.
Not every video or digital slideshow needs to capture a feedback form. Not every office or engineering dashboard needs to have catchy moving images to do its job.
When beginning your activity, it's sound business sense to first define the goals you have - as attention might simply be enough!
Placement and Personalisation
As a physical device - placement is important. As its aimed at human attention, personalisation may also become integral to your success.
Consider the placement of your hardware unit for maximum attention - should people have to walk around it or simply past it? Do you want people to linger - or would this create an obstruction?
Consider whether it is physically reachable if you require interaction - you can offer a questionnaire if the buttons can't be reached by everyone (including wheelchair users, or children).
Decide if you need language options, back buttons, or whether QR codes could move the experience into their handheld devices?
Maximising your Chances of Data
Touchscreen devices are the way to go if you want to maximise your chances of data collection. Put simply they give the customer more opportunities to engage and interact with your campaigns.

How to Measure Digital Signage Success Effectively
In terms of hard data - often for campaigns of interaction - there are several ways you can glean useful insights:
1. Use QR Codes
A powerful way to gather interaction data as well as extending the timespan of engagement is to use QR codes. By moving them to their mobile, you allow the user to browse at their leisure, and even come back time and again, making you more memorable and part of their life.
Ultimately the QR code will take them to a web hosted page that can be monitored - an event ticketing page, a downloadable product PDF, a video with views tracking. But imagine being able to track the location, duration and other activity after they've opened the QR code... Flowcode could help.
Tip: When using QR codes on digital displays, ensure the code is large enough to scan from the typical viewing distance - a minimum of 10cm square for a screen viewed from one metre, scaling proportionally for larger displays viewed from further away. Codes that are too small to scan reliably are one of the most common and easily avoided failures in digital signage QR integration.
2. Create Specific URLs
Similar to the QR code, specifically created web pages (urls) are trackable and continually editable so you can refine the message delivered.
Instead, a touchscreen DDV for example can show the webpage on the digital hardware unit directly - good for exhibitions, wayfinding, or answering immediate queries.
3. Use Tag Manager / Hotspots
Sometimes - to monitor engagement - you simply need to know a user has touched the screen. You might not wish to create multiple trackable web pages, instead wanting to keep the interaction on screen.
Whether an engineering floor passing crucial production data to its team, or a cafe customer being interested in the vegetarian menu options, a 'next page' or 'see more' click that reveals another screen can be enough to provide data - like how popular veggie options are.
4. Assess the Dwell Time
Data gathering can be more subtle and human than that, and can also have positive knock on effects.
Take a travel agency for example. Showcasing the latest hotels deals for Turkey, or the various destinations a user can fly to from Stansted, can increase dwell time - something easily noticeable by agency staff. In turn, the agents may be asked more questions, more brochures and leaflets might be taken away, or more sales opportunities might present themselves. In an agency environment, dwell time is rarely tracked formally, but it can be correlated with other outcomes. If the number of brochures taken, consultations booked, or simply questions asked by customers increases after a new display is installed, dwell time is the most likely mechanism. Sometimes the most useful measurement is the simplest: ask your staff whether the screen is changing conversations.
5. Monitor Footfall Changes
There's nothing like the buzz of a busy store, especially if your new digital promo get the people through the door. Your shop window sequence was far more eye catching than anyone else on the street, and it's you that are benefitting from so much more interest.
Yet footfall numbers can be harder to ascertain - which is why companies like HoxtonAI offer physical hardware to track incoming numbers. Hardware/software like these can help manage staff numbers, justify marketing spend, and can even relate to purchase conversion numbers.
For smaller businesses where hardware footfall counters aren't practical, a simpler proxy is transaction count - if the number of paying customers increases, footfall has likely increased. It's a less precise measurement, but it's directionally valid and requires no additional hardware.
6. Encourage Data Submissions
Feedback forms, questionnaires, offer newsletters sign ups - there's many ways to capture a person's email address or mobile number in order to begin follow up marketing.
A touchscreen unit makes it easy for your customers to claim offers, sign up for forthcoming events or leave a great review for your business.
The One Thing to Take Away
Measurement is not the same as proof. Digital signage rarely generates the kind of clean, attributable data that a paid search campaign does, and trying to hold it to that standard will always produce disappointing results. What it generates instead is a pattern: footfall goes up, dwell time increases, staff report more questions being asked, transaction values creep higher. None of those changes is solely caused by a screen. But together, over time, they build a picture that's hard to argue with.
The businesses that get the most from digital signage measurement are the ones that set realistic expectations before installation, track consistently against a clear baseline, and evaluate the screen as one component of a wider commercial environment - not as a standalone campaign with a single measurable outcome.
