A Marketer’s Introduction to DOOH Retargeting

Traditional billboards have become outdated in recent times, often serving as one-way broadcasts that hardly improve consumer traffic. Digital Out-of-Home (DOOH) retargeting, however, transforms physical advertisements into digital catalysts. This technology closes the gap between seeing a brand on the street and engaging with it on a mobile device. 

What Is DOOH Retargeting?

DOOH retargeting is when a physical display is connected to a private screen. A key benefit of retargeting is that it identifies who actually saw the ad using anonymized mobile location data, rather than sending a message to everyone. This allows for a level of audience-specific reinforcement that regular billboards could never achieve. 

The process begins with a geofence. Marketers draw a digital perimeter around a physical location, and when a consumer enters this zone with a mobile device, the system tags an anonymous ID. This allows the brand to serve a mobile ad later that reinforces the initial physical encounter. 

The Strategic Benefits of Physical-to-Digital Workflows

Combining high-impact assets with strategic follow-ups addresses the forgetfulness that passersby often experience, especially in areas with other physical advertisements and high foot traffic, such as transit hubs. 

A consumer might get intrigued by an impressive wrap while commuting, but forget the brand by lunchtime. DOOH retargeting can keep the message top-of-mind by serving social media content after. Studies show consumers are 28% more likely to notice social media ads when they have first seen the brand in a physical DOOH campaign.

This approach is also cost-effective compared to alternatives. DOOH retargeting enables precision, reducing wasted ad spend. Rather than blanket-advertising in a city with digital content, you can focus your budget on people who have already encountered your brand in the real world, leading OOH advertising companies with digital retargeting to have a higher volume of warm leads. 

How to Implement a DOOH Retargeting Strategy

The first step is finding the right location. You must choose a setting with high visibility for your target audience. This could be a tech corridor for B2B or a retail shopping district. The physical ad’s job is simply to build awareness and establish the visual hook for the entire campaign. 

The next step involves programmatic apps. These platforms help identify the device IDs of people who were within your geofence for processing. Then, this data is passed through a Demand-Side platform to create an audience segment, where a prospect list is built through real-world movement analysis. 

3 OOH Advertising Companies Doing Digital Retargeting Right

These three leading OOH companies have demonstrated excellence in implementing digital retargeting methods, serving as strong examples of the potential of DOOH retargeting campaigns for the marketing landscape. 

GOOD TRAFFIC

GOOD TRAFFIC has built a reputation as a leading OOH advertising company with digital retargeting, thanks to its bold physical advertising campaigns that turn high-end rideshare vehicles into moving digital primers. The company has been an innovative leader in the advertising space, particularly through its proprietary shadowfencing technology, which leverages street-level visibility to drive real digital conversions. Wrapped vehicles pass through city areas and identify close-proximity mobile devices to form a retargeting pool, whose data is interpreted by marketers who subsequently serve follow-up ads. 

For its Klarna campaign in New York City, GOOD TRAFFIC deployed a fleet of wrapped Teslas. This campaign brought together stunning aesthetics and precise data capture, resulting in mass awareness among urban shoppers and precise retargeting to a high-intent digital audience. 

Wrapify

Wrapify is a prominent OOH advertising company that specializes in vehicle wraps and digital retargeting. Its platform uses GPS and proximity data to identify mobile devices that have been exposed to their wrapped vehicles, allowing marketers to build a custom audience segment based on real-world exposure. This allows targeted digital ads to be served later. 

One of Wrapify’s most notable projects was an impressive campaign for ZOOM in 2019. Using Account-Based Marketing and sending wrapped vehicles to business hubs, the company successfully targeted high-value decision-makers who work and commute there. The strategy resulted in a staggering 102% increase in contact sales conversion rates.

Firefly

Firefly is a leading OOH advertising company that utilizes smart digital displays mounted on rideshare and taxi vehicles. Its technology captures anonymized mobile device data from people who pass within the vehicle’s proximity. This data enables advertisers to retarget specific individuals with mobile display ads later.

For a project that it did for Puma, Firefly deployed its digital toppers to target urban shoppers near the sports brand’s stores. The campaign successfully drove consumers into physical retail locations with effective retargeting, leading to a 136% increase in store foot traffic. This further demonstrates the power of linking mobile billboards with digital retargeting, especially when consumers have shown prior interest in physical stores. 

Maximizing DOOH Success

While many marketers believe the industry’s future is fully digital, blending the irreplaceable boldness of physical advertising is a powerful move. For brands looking to establish authority, this strategy creates a marketing funnel that is both highly visible and highly effective.

Transition from call ads to responsive search ads with call assets

Google Is Killing Call-Only Ads: Here’s What You Need to Do

If you’ve been running Google Ads for a while, you may have gotten an email recently with the subject line “Action Required: Transition from call ads to call assets.” Google has been talking about this change for a while, but now it’s official. Call-only ads are going away, and if you don’t make some updates, your ads will stop showing.

Here are the key dates:

February 2026 is when you lose the ability to create new call-only ads. February 2027 is when your existing call-only ads stop running entirely.

So you have time, but not unlimited time. Let’s walk through what this means and what you need to do.

First, Check If This Even Affects You

Not everyone needs to worry about this. Call-only ads are a specific ad type where the only thing the ad does is trigger a phone call. There’s no website link. When someone taps the ad, it just dials your number. These were popular with service businesses like plumbers, auto repair, locksmiths, and anyone else who just wanted the phone to ring.

If you’re running regular search ads that happen to have a phone number attached, you’re already set up the way Google wants. That phone number is a “call asset,” and you’re good to go.

To check, log into your Google Ads account and look at your ads. If you see ads that have a website URL and a phone number, those are search ads with call assets. You’re fine. If you see ads where the only action is “Call” with no website destination, those are call-only ads, and those are the ones you need to replace.

Why Google Is Making This Change

Google wants everyone using responsive search ads. These are the ads where you provide multiple headlines and descriptions, and Google’s system mixes and matches them to find the best performing combinations for different searches.

The old call-only ads were simple. You wrote your headlines, attached your phone number, and that was it. Google is moving away from that kind of static ad format across the board. They want the flexibility to test different combinations and optimize automatically.

Whether that’s actually better for your business is a fair question, but it’s the direction things are going and it is always good to stay in compliance.

How to Make the Switch

If you do have call-only ads that need to be replaced, here’s the process:

Start by documenting what you have. Look at your existing call-only ads and write down the headlines, descriptions, and which campaigns they’re in. Note the performance numbers too so you have a baseline to compare against later.

Next, create your call asset. Go to Assets in the left menu, then click the plus button and select Call. Enter your business phone number. You can set it to only show during your business hours, which is useful if you don’t want calls coming in at 10pm.

Then create a new responsive search ad in the same campaign or ad group where your call-only ad was running. You’ll need at least 3 headlines and 2 descriptions, but you can add up to 15 headlines and 4 descriptions. Use the copy from your old call-only ad as a starting point, then add variations.

Once your new responsive search ad is running with the call asset attached, let both ads run side by side for a few weeks. Compare the results. When you’re confident the new setup is performing well, pause the old call-only ad.

So to recap here is what you need to do:

Create responsive search ads with call assets.

This is the actual migration. You’ll need:

  • 3-15 headlines (at least 3 required)
  • 2-4 descriptions (at least 2 required)
  • A call asset attached at the campaign or ad group level with your phone number

Set up the call asset

This is under Assets > Call. You can set it to show only during business hours, which is nice for a service business like auto glass.

Let both run in parallel for a bit

Compare performance before sunsetting the old call-only ads.

Don’t Wait Until the Last Minute

You have until February 2027 before your call-only ads stop serving entirely, but I wouldn’t recommend waiting that long. Making the switch now gives you time to test and optimize. If something isn’t working, you want to find out while you still have your old ads as a backup.
