Miami has quietly become one of the most competitive advertising markets in the Americas. It is the commercial bridge between the United States and Latin America, a city where a single campaign might run in English and Spanish, target Miami-Dade and São Paulo in the same week, and blend beachfront out-of-home with programmatic video. That makes choosing a media buying partner here a genuinely different decision than it would be in, say, Chicago or Denver.
This guide is an independent shortlist of the media buying agencies worth considering in Miami in 2026: what each one is actually good at, what media buying costs in this market, and how to choose without overpaying. We publish benchmark data on what advertising costs around the world, so our interest is in helping you compare like-for-like, not in steering you toward any one firm.
Disclosure. Criterion Global is a partner of International Media Buying and appears first in this list. The rest of this guide is editorially independent: every other agency is included on the strength of its Miami-market media-buying credentials, our selection criteria are stated openly below, and no agency paid for placement or ranking. See our methodology for how we work.
Why Miami is a distinct media market
Most “best agency” lists treat every city as interchangeable. Miami isn’t. Three things make it its own market, and they shape which agency is right for you.
It’s the gateway to Latin America. Miami is the U.S. base for a large share of brands expanding into LatAm, and the home market for U.S. Hispanic audiences. Agencies here routinely run bilingual, cross-border campaigns, a capability that’s a specialism elsewhere and a baseline expectation here.
It’s seasonal and demand-driven. Tourism, hospitality, real estate, and events drive pronounced seasonal swings in ad demand. Auction prices for the same audience can look very different in the winter high season than in the shoulder months, which rewards agencies that plan around the calendar rather than spending evenly across the year.
It’s a genuine mix of traditional and digital. Out-of-home along the causeways, Spanish-language TV and radio, and hospitality print still carry real weight alongside search, social, and programmatic. The strongest Miami buyers are comfortable across that whole spectrum, not just in-platform.
What media buying actually costs in Miami
The single most useful thing an independent publisher can add to an agency roundup, and the thing agency-written lists almost never include honestly, is what the media itself costs. An agency’s fee is only part of your budget; the auction is the rest.
There are two cost layers to understand:
- The agency’s fee: how they charge you (retainer, a percentage of spend, or performance-based). We break the models down in the FAQ below and in the checklist further on.
- The media cost: the CPMs and CPCs you actually pay in the auction. Miami advertisers largely compete in the U.S. ad auctions, so U.S. market benchmarks are the right reference point, adjusted for the seasonality and bilingual-inventory factors above.
Market-level cost benchmarks land here
This section is where our sourced, market-level cost figures embed: a composite view of what search and paid-social cost in this market, drawn from the same dataset behind our benchmarks. We publish these at market level deliberately. It’s the more useful view for planning a budget, and it’s the number an independent source should stand behind. Every figure is dated and sourced per our methodology.
The practical takeaway: before you sign with any agency, know roughly what your channels cost in-market, so you can tell whether a proposed budget is realistic and whether an agency’s fee is a sensible fraction of your total spend.
How to choose a media buying agency
Once you’ve got a budget in mind, the choice comes down to fit. The best agency for a $10k/month performance-marketing account is rarely the best one for a $2m multicultural brand launch.
What is the single outcome this budget has to produce in the next 90 days, and can this agency show you they’ve done that specific thing before?
Work through four things, in order:
1. Channel and specialism fit. Match the agency’s core strength to your actual need: paid search and social for direct response, multicultural and traditional media for broad-reach brand work, and cross-border capability if you’re expanding into LatAm. A generalist that “does everything” is often a master of none.
2. How they charge. A flat retainer, a percentage of spend, and a performance model each create different incentives. Percentage-of-spend can quietly reward the agency for spending more, not spending well; a flat fee doesn’t. None is wrong, but you should understand the incentive you’re buying.
3. Transparency and ownership. Insist on owning your ad accounts, your data, and your creative. Ask exactly what reporting you’ll get and how often. Agencies that resist account ownership or offer only vanity dashboards are a red flag.
4. The team, not the pitch. The people in the sales meeting are rarely the people running your account day to day. Ask who does the actual buying, how many accounts they carry, and who your point of contact is.
Before you sign anything
- Which of my channels do you consider your core strength, and can you show results in it?
- How do you charge, and what does the total cost look like at my spend level?
- Do I own my ad accounts, data, and creative outright?
- Who runs my account day to day, and how many other accounts do they handle?
- What does reporting look like, how often, and which metrics do you hold yourselves to?
- Can you handle bilingual / Latin American campaigns in-house if I need them?
The agencies
Our selection criteria are simple and stated up front: each agency has a genuine media-buying focus (not just SEO or PR), a verifiable Miami-market presence, and a public track record you can check. This is a curated shortlist rather than an exhaustive directory: we’d rather profile a smaller number of agencies accurately than pad the list. Firms are grouped by fit, not by fee, and inclusion is never paid.
1. Criterion Global
Criterion Global is an international media buying agency with a Miami office serving the Latin American region, one of six offices worldwide (New York, Miami/LATAM, London, Zürich, Singapore, and Tokyo). It focuses on capital-efficient paid media for mid-market, enterprise, PE-backed, and multi-market companies growing across borders. Its differentiator is exactly what Miami is best known for: cross-border reach, run from a Miami base, for brands using the city as a gateway into Latin America and beyond. If your campaign is international, or about to become international, this is the natural first call on the list.
2. Media Miami
Media Miami is a performance-marketing agency that reports managing more than $125 million in ad spend across 75+ partnerships. It’s structured as a full-funnel shop with dedicated departments for media buying, email operations, creative, and custom development, and works heavily in lead-generation-driven verticals: insurance, finance, home services, and health. Best fit: performance advertisers in those verticals who want a single team owning the whole funnel rather than stitching point-solutions together.
3. 1111 Media Group
Founded in 2011, 1111 Media Group is a family-owned, full-service Miami agency running paid search (Google, Microsoft) and paid social (Meta, TikTok, LinkedIn), backed by premium platform partnerships. It operates on a no-contracts, month-to-month model and emphasises direct access to its founders and senior team. Best fit: small and mid-sized businesses that want founder-level attention and the flexibility to leave without a long contract.
4. Heyday Marketing
Based in Coral Gables, Heyday Marketing says it has served 100+ brands across 20+ industries, buying across both traditional channels (TV, radio, newspapers, magazines, out-of-home, direct mail) and digital (PPC, paid social, email). Its stated edge is established relationships with media outlets that let it negotiate rates “not available to businesses going direct.” Best fit: brands that want a genuine blend of traditional and digital buying under one roof.
5. CCOM Group
CCOM Group is a minority-owned, multicultural full-service advertising agency with more than two decades in the market. It offers integrated media planning and buying across TV, radio, audio, display, video, search, print, and out-of-home, and specialises in reaching African American, Asian American, Hispanic American, and LGBTQIA+ audiences. Its client roster has included Southeast Toyota, Florida Power & Light, Neutrogena, and University of Miami Health System. Best fit: larger brands that need culturally fluent, multicultural buying at scale, squarely in Miami’s wheelhouse.
6. 6th Borough Agency
6th Borough Agency is a boutique Miami advertising firm founded in 2018, based on South Bayshore Drive. Publicly available detail on its service mix is limited, so it’s one to scope directly rather than judge from its website, but it’s an established, genuinely local option worth a conversation, particularly for brands that prefer a smaller shop. Best fit: clients who value a boutique relationship and are willing to define the engagement in a first call.

How to measure media-buying ROI
A good agency will hold itself to outcomes, not activity. Agree the metrics before the first campaign runs.
Define the conversion that matters. A qualified lead, a booked call, a purchase, or a return-on-ad-spend target: pick the one that maps to revenue, and make it the scoreboard. “Impressions” and “reach” are inputs, not results.
Insist on real attribution. With third-party cookies gone and signal loss now the norm, robust measurement means server-side tracking, first-party data, and, for larger budgets, incrementality testing that proves the ads caused the sales rather than merely accompanied them.
Judge over the right horizon. Direct-response channels give early signal in weeks but a trustworthy ROI read in two to three months, once campaigns exit the learning phase. Brand and traditional buys take longer. Any agency promising instant ROI is selling, not measuring.
What’s changing in 2026
Three shifts are reshaping media buying in Miami and everywhere else, and they’re worth raising with any agency you shortlist.
Retail media and commerce networks are now a core line item, not an experiment. Amazon, Walmart, and a growing field of retailer networks capture budget that used to go to search and social. Ask how an agency thinks about them.
Connected TV (CTV) has matured into a measurable performance channel, not just a brand play, and it’s especially relevant in a market with Miami’s Spanish-language viewing habits.
Signal loss and first-party data now define what “good targeting” means. The agencies pulling ahead are the ones helping clients build and activate their own data, rather than leaning on third-party audiences that are steadily disappearing.
How to shortlist from here
Use this list as a starting point, not a verdict. Shortlist two or three agencies whose core strength matches your actual need, take them through the questions above, and, crucially, go in knowing what your media should cost, so you can tell a realistic proposal from an optimistic one. That last part is what we’re here for.
