How to Do Advertisement: A Practical Guide to Running Ads That Work

By Livy Phillips | American Guerrilla Marketing

Advertising sounds simple until you try to do it. Then the questions pile up fast. Where do you place your ads? What do they say? How much do you spend? How do you know if it worked? We have been in the advertising business for a long time, and we still think through every one of those questions on every campaign we run. This guide breaks down how to do advertisement from beginning to end.

Whether you are promoting a product, an event, an artist, or a brand, the fundamentals are the same. You need a message. You need an audience. You need a medium. And you need a way to know if it worked.

Step One: Define What You Are Advertising and Why

Before you touch any creative or spend any money, get clear on the core purpose. What are you advertising? What do you want the person who sees your ad to do? Those two questions sound obvious, but most advertising problems start with vague answers to them.

Your advertisement serves one of a few core purposes. Sometimes it is awareness. You want people to know your brand exists. Sometimes it is conversion. You want people to buy, register, attend, or download. Sometimes it is both, with awareness now and conversion later.

Write down the purpose in one sentence before you go further. That sentence will guide every decision about message, format, timing, and placement.

Step Two: Know Your Audience

The best ad in the world fails if it reaches the wrong people. Audience definition is the most important step in the advertising process, and it is the one most brands rush through.

Ask these questions. Who buys what we sell? Where do they live? How do they commute? What do they read, watch, and follow? What neighborhoods do they spend time in? What events do they attend? What time of day are they most receptive to new information?

Those answers determine your medium. If your audience walks through Soho every day, outdoor advertising in Soho reaches them. If they spend two hours a day on Instagram, social ads reach them. If they commute on the subway, transit advertising is your channel. The medium follows the audience. Never the other way around.

Audience First, Always
We have never seen an advertising campaign succeed by starting with the medium. The brands that win start with deep audience knowledge and then find the channels that access that audience most efficiently.

Step Three: Choose Your Advertising Medium

There are more advertising mediums available today than at any point in history. The challenge is not finding options. It is choosing the right ones for your audience and goals.

Most effective campaigns use more than one medium. A launch might combine outdoor postering to build street-level awareness, social ads to capture intent, and experiential events to deepen engagement. The mediums reinforce each other. Someone who sees your poster on the street and then sees your social ad is far more likely to respond than someone who sees only one of those touchpoints.

Step Four: Develop Your Creative

Creative is the message your audience actually sees or hears. It is the ad itself. Strong creative follows a few principles that hold across every medium.

One Clear Message

Every advertisement should communicate one thing. Not three things. Not a list of features. One compelling idea that makes the audience stop and pay attention. The more you try to say, the less gets retained. Clarity beats comprehensiveness every time.

A Reason to Care

What is in it for the audience? Why should they pay attention? Your ad needs to answer that question in the first second. The benefit, the emotion, or the intrigue needs to be immediate. If you lead with what the brand wants rather than what the audience gets, you lose them immediately.

A Call to Action

Every ad needs to tell people what to do next. Visit this website. Call this number. Come to this location. Use this code. The call to action does not need to be aggressive. But it needs to exist. Ads without clear next steps generate attention but not results.

Visual Hierarchy

The eye moves in patterns. The most important element of your ad should be the most visually dominant. For an event, that might be the artist’s name. For a product, it might be the product image. Design your ad so the most important information gets seen first, and secondary details support rather than compete.

Step Five: Set Your Budget and Allocate It

Budget conversations are uncomfortable, but skipping them is more expensive. A vague budget produces a vague campaign.

Start with what you can realistically spend. Then divide it across three areas. Creative production takes a portion. Media placement or campaign execution takes the largest portion. And measurement and reporting takes a small portion.

A common mistake is spending almost everything on production and leaving almost nothing for distribution. A beautifully produced ad that no one sees is worthless. A simpler ad placed with enough frequency in the right locations will always outperform a polished one that never reaches the audience.

Step Six: Execute the Campaign

Execution is where most advertising plans break down. The strategy was good. The creative looked right. But the actual rollout was late, inconsistent, or poorly managed.

Good campaign execution requires a timeline that works backward from the launch date. It requires clear ownership of every task. It requires a quality check at every stage. And it requires flexibility, because campaigns that run in the real world encounter real-world problems.

For physical advertising like postering, street teams, or experiential activations, we manage the full execution. We put crews on the ground, document every placement, and report back with confirmation of what ran and where. We do not outsource verification to the client.

Step Seven: Measure and Learn

Measurement is the part of advertising that most brands underprioritize. After a campaign ends, the instinct is to move on to the next one. But campaigns that are not measured are campaigns that cannot improve.

Match your measurement to your objective. If the goal was awareness, measure reach and recall. If the goal was traffic, measure visits and page views. If the goal was sales, measure revenue. Then compare the result to the investment and the baseline before the campaign. That comparison tells you what worked, what did not, and how to do better next time.

The Most Important Question After Any Campaign
What did we learn? Not what happened, but what does it mean for the next one? Campaigns that inform future campaigns compound in effectiveness over time. That is how brands build sustained advertising advantage.

How Outdoor Advertising Fits Into the Mix

Out-of-home advertising is one of the oldest advertising mediums and one of the most effective in urban markets. Street posters, transit ads, and large-format prints reach people in the physical world where they cannot turn the channel, close the app, or scroll past your message.

In cities like New York, Los Angeles, and Chicago, where walkability is high and screens are everywhere, outdoor advertising creates presence in a way digital cannot. When someone sees your poster on their walk to work, it occupies a different mental space than the banner ad they ignored on their phone. Physical ads have weight. They claim territory.

We specialize in outdoor advertising campaigns that combine street postering, snipe campaigns, and large-format installations to build comprehensive physical presence in target markets. If your audience walks, we can reach them.

Advertising for Different Business Sizes

The principles of advertising are the same regardless of budget. The execution scales.

Small businesses can run hyperlocal campaigns in one neighborhood with poster placements and social ads at a very modest budget. The focus is tight and the impact is concentrated. That concentration is an advantage. You are not trying to reach the whole city. You are dominating your block.

Mid-size brands expand the geographic footprint, add channels, and increase frequency. More placements, more platforms, more touchpoints. The audience encounters the campaign at multiple points across their daily life, which increases both recall and response.

Large brands run multi-channel, multi-city campaigns with coordinated creative across every medium. The scale requires more sophisticated planning and execution but follows the same principles. Clear message, right audience, right medium, strong creative, measurement.

Testing Your Advertising Before You Scale

Most brands skip testing. They develop creative, commit budget, and launch at full scale. If the creative is wrong, they find out late and the loss is large.

Smart advertisers test before they scale. That means running a smaller version of the campaign in one neighborhood, on one social platform, or to one audience segment first. You read the results. You assess what resonated and what did not. Then you adjust and scale what works.

In digital advertising, this is A/B testing. You run two versions of an ad at the same time and measure which produces better results. The winner gets the bulk of the budget. The loser teaches you something about your audience’s preferences that you can apply to the next campaign.

In physical advertising, testing looks different but follows the same logic. We sometimes run poster campaigns in two different neighborhoods at the same time to see which generates more social documentation, more brand search lift, or more direct response. That comparison tells us which audience segment and which geographic environment is most productive for the brand, and we concentrate the next campaign budget accordingly.

Testing is not a luxury for brands with large budgets. It is a discipline that saves money and improves outcomes regardless of budget size. A brand spending $5,000 on advertising that tests two creative directions with $1,500 each and scales with the remaining $2,000 will outperform a brand that puts all $5,000 behind a single untested concept every time the data is available to inform the decision.
