Guerrilla marketing with creators: city actions, ambient marketing and spreading them on social media

Guerrilla marketing is a low-budget action in public space that surprises passers-by and gets people talking. Seen only on the street, the action reaches just the people who happen to walk past. When local creators film it and post it on social media, that single day in the city can be seen by their audiences across the whole region. That is why guerrilla marketing today is planned for the camera from the start: idea, location, creators on site, brief, filming, publication and measurement.

The simplest way to gather such creators is to publish a task describing the action, the city and the date — this is how Blogger Bank works, among others: local creators apply to the task themselves. You can also look for them manually on social media or through an agency. Below we walk through the whole process step by step.

What guerrilla marketing is and how it differs from ambient marketing

Guerrilla marketing is promotion built on an idea rather than a media budget. Instead of buying ad space, a brand does something unexpected where people already are: a square, an underpass, a bus stop, a park. What counts is the surprise and the moment someone pulls out their phone.

In practice, guerrilla marketing with creators combines two things: an offline action and online distribution. The action provides authentic footage, and creators give it reach and credibility, because they show the event through their own eyes rather than as a brand ad.

Why creators multiply the reach of a city action

A physical action has a natural limit: only those passing by see it. A creator removes that limit in three ways.

• They film reactions, not just the object. The most interesting part of guerrilla is the faces of people discovering something. Creators know how to capture that in the first seconds of a video.
• They speak to a local audience. A Kraków creator showing an action in Kraków's main square reaches people who could come there the day after tomorrow. That turns the video into an invitation.
• They leave footage for further use. Recordings of the action are ready-made UGC that the brand can, once rights are agreed, use in its own channels and ads.

It is worth distinguishing this from viral marketing. A viral is content designed so that people share it online themselves — we cover that in the article on viral marketing with creators. Guerrilla starts in the physical world, and the internet is its amplifier. Word-of-mouth recommendations in conversations and comments are a separate topic again: whisper marketing.

Ambient marketing — advertising built into the surroundings

Ambient marketing is a type of guerrilla in which an element of the environment becomes the carrier of the message: a bench, stairs, a tram handrail, a puddle, a building's shadow. The ad does not hang next to the space, it uses it. A good ambient object is understandable without a caption and instantly linked to the product.

Ambient has one advantage when working with creators: the object stays longer than a one-off action. Creators do not have to be there at a specific hour; they can come over several days, film it their own way and show their friends' reactions. You get several different takes on the same idea instead of one report.

Example directions, without pointing to specific campaigns:

• a pet food brand turns a city drinking fountain into a "dog bar" with a bowl and a slogan;
• a home goods brand sets up a complete, cosy living room with a sofa in a park where people can rest;
• a car brand paints an oddly shaped parking space that refers to a feature of the car;
• a food brand places a "fridge" with free snacks at a bus stop during set hours.

Guerrilla marketing formats that look good on camera

Not every format works equally well on social media. These perform best because they have a clear moment of reaction.

Street action

A short interaction with passers-by: an invitation, a challenge, a game, an unusual question. For a creator it is a ready video structure: set-up, reactions, punchline. Participation should be voluntary and pleasant for people.

Ambient object

An installation built into the surroundings, described above. It lasts longer, produces lots of content from different creators and does not need staff all day.

Pop-up

A temporary spot for a few hours or days: a mini shop, a tasting stand, a test zone. A pop-up gives creators a reason to invite their followers: "I'll be there on Saturday, drop by". It is also a good format for brands that want people to touch the product.

Light flash mob

A short, planned moment in which a few people do something in sync: a dance, freezing in place, a shared shout. You do not need hundreds of participants. A dozen or so people plus well-placed creator phones are often enough for strong footage.

Product in an unexpected place

The product appears where nobody expects it: an exercise bike at a bus stop, a game console in a waiting room, a blanket and thermos on a cold platform. A simple idea, easy to film and understood in seconds.

How to plan a guerrilla action with creators step by step

Step 1. One idea, one sentence

Start with a sentence describing the action the way a passer-by would tell a friend about it. If you need three sentences, the idea is too complicated for a video. Also note what the viewer should remember: a product feature, a slogan or a place they can visit.

Step 2. Location and permissions

Choose a spot with foot traffic, good light and a background that does not hide the action. Before you set anything up or organise anything, check the required permissions with the city or the owner of the site.

Step 3. Local creators

For a city action, look for creators who live there and whose audience is local. For example, in the catalogue of Warsaw creators or Kraków creators you can browse profiles by city. Match the niche to the idea: an action with dogs calls for pet creators, a snack pop-up for food creators, an unusual parking space for automotive creators. For such actions micro-influencers often work better, because their followers live nearby.

Invite several creators, not one. Each will film the action differently, and if one does not make it, the action still gets shown.

Step 4. Brief for creators

A guerrilla brief is shorter than a standard ad brief, but it must include a few things:

• date, hours and exact location, with a backup plan for rain;
• what will happen and the moment that must not be missed;
• one thought the viewer should remember;
• what not to do: do not film faces of people who did not agree, do not block the way;
• format and platform, publication date and the collaboration label;
• scope of rights to the footage if the brand wants to use it in its channels.

Give creators freedom in how they tell the story. The action should look like something they stumbled upon and found interesting, not a script read out loud.

Step 5. Filming on site

Appoint one person from the brand who is on site and handles contact with creators. Agree who films from where so creators do not stand in each other's shots. The first minutes are the most valuable, because reactions are most spontaneous then — creators should be ready before the start.

Step 6. Publication

Set a publication window: ideally the same or the next day while the action is fresh, and for a pop-up or ambient object, while it is still running so followers can come. Posts spread over several hours stay in feeds longer than all at once. Every piece must be labelled as a collaboration.

Step 7. Measurement

You measure guerrilla in two layers. Offline: how many people took part, how many samples were handed out, how many people came to the pop-up with a slogan from the video. Online: views, saves, shares and comments for each creator, clicks on a link with a code or UTM parameter, growth in brand-name searches in that city. Record a baseline before the action so you have something to compare against.

How to test the idea before you go out on the street

A guerrilla action happens once, so there is no room for fixes along the way. Before you order props, run a few simple tests.

• The five-second test. Describe the action to someone outside the team in one sentence and ask what they understood. If they cannot repeat it, the viewer on a phone will not get it either.
• The silent test. Many people watch videos muted. Picture the first frame without commentary — is it already clear that something unusual is happening.
• The product test. Remove the logo from the idea. If the action still evokes your category, for example electronics or home, it works. If it fits any brand, viewers will not remember yours.
• The safety and kindness test. Check that the action will not scare anyone, block a walkway or leave a mess. Negative comments under a video can bury the whole idea.

It also helps to ask one of the creators for an opinion before the action. Creators in technology or home think every day about what stops their followers' thumbs, and often suggest a simpler version of the idea.

Checklist for action day

• Confirmed permissions and a contact for the person responsible for the site.
• A list of creators with arrival times and the coordinator's phone number.
• Props, spare product and a rain plan.
• Agreed filming spots and start moment.
• A sign or board telling passers-by what the action is about.
• A person counting participants and samples handed out.
• An agreed publication window and collaboration label.
• A clean-up plan for the end.

The most common mistakes in guerrilla with creators

• An idea that only works live. If the action cannot be understood from a short silent video, it will not work online.
• One creator for the whole action. One late arrival and there is no footage.
• Too much brand. A logo on every inch turns surprise into a regular ad.
• No plan for weather and crowds. Rain or too much interest can stop the action halfway.
• No offline measurement. Without counting participants you do not know whether the action or just the video worked.

How Blogger Bank solves gathering local creators for a guerrilla action

The hardest part of guerrilla with creators is having the right people with cameras on site in a given city on a given day. On Blogger Bank it works like this:

• Instead of hunting for creators in a city by hashtags — you publish a task describing the action, the city and the date, and local creators apply themselves.
• Instead of sending the brief across several messengers — you describe everything you expect once in the task, and the contract with each chosen creator opens automatically.
• Instead of collecting videos and links from different places after the action — conversation with the creator, content approval and payment are in one place.

You can also browse the influencer catalogue by city and niche and invite specific people. Create a brand account and publish a task for your first city action.
