What is media buying?
Media buying is the purchase of advertising placements: a slot, an impression, a click or an action on a site, in an app, on a social platform or inside an ad network. The word comes from classic advertising, where it meant booking television, radio, print and outdoor space. Today most media buying is digital and happens in auctions or through direct deals with publishers.
In general marketing, planning and buying are separate steps. A planner decides who to reach and with what budget; the buyer negotiates or bids for the inventory, launches the ads and optimises them once they run.
In performance and affiliate marketing the word has a narrower, practical meaning. A media buyer pays for traffic, sends it to an offer from an affiliate program or a CPA network, and earns a commission when visitors complete the target action. The goal is not reach or brand awareness. It is a campaign where commission income is higher than the cost of the traffic that produced it.
What does a media buyer do day to day?
A media buyer owns the loop between spend and result. The job usually breaks down into five repeating tasks:
- Choosing an offer and a GEO. The buyer picks what to promote and where, reading the program’s terms: allowed traffic types, restricted sources, payout model, hold and minimum payout.
- Selecting a traffic source. Each source suits different offers and audiences, and each has its own rules for what may be advertised.
- Building the campaign. That means creatives, a landing page or pre-lander, tracking links, targeting and a starting bid and budget.
- Testing. Small budgets go to several creatives, audiences and placements. Most tests do not pay back, and the point is to find the few that do quickly and cheaply.
- Optimising and scaling. The buyer excludes weak placements, adjusts bids, refreshes creatives as they wear out, and raises budgets on campaigns with stable profit.
Alongside this runs routine work: reporting, reconciling tracker numbers with the offer’s statistics, checking that payouts arrive on time, and keeping accounts and payment methods in order. Platform policies also need regular review: rules for gambling-related advertising differ by source and country, and they change often.
Media buying vs affiliate marketing vs traffic arbitrage
The three terms are often used as if they were interchangeable. They describe different things: a model for earning, a way of getting traffic and a business approach.
| Affiliate marketing | Media buying | Traffic arbitrage | |
|---|---|---|---|
| What it is | A commission-based model: you promote someone else’s offer | A way of getting traffic: paying for ad placements | A business model: buy traffic for less than the offer pays |
| Where traffic comes from | Content, SEO, email, communities, or paid ads | Paid sources only: ad networks, social platforms, other inventory | Paid sources |
| Who earns what | Commission from the advertiser | Commission, salary or revenue share, depending on the setup | The spread between payout and traffic cost |
| Main skill | Content, audience building, partner negotiation | Campaign setup, bidding, testing, analytics | Unit economics and scaling |
| Time to results | Often slow for organic content | Fast feedback, so fast losses too | Fast feedback |
Media buying is therefore not an alternative to affiliate marketing but one way of doing it. A content affiliate who publishes reviews earns traffic over time; a media buyer who runs paid campaigns to the same offer buys it. For the business-model view, see our guide to what traffic arbitrage is. The two overlap heavily: arbitrage names the strategy, media buyer names the person and the process.
How is paid traffic priced: CPM, CPC and CPA?
Sellers of traffic charge in a few standard ways, and the choice decides who carries the risk.
- CPM (cost per mille): you pay per thousand impressions, whether anyone clicks or not. Common for awareness formats and some display and video inventory. The buyer carries the full risk of poor conversion.
- CPC (cost per click): you pay for each visit. It is the usual model for search, social, push and native advertising. The buyer carries the risk after the click: landing page and offer conversion.
- CPA (cost per action): you pay only when a defined action happens, such as a registration or first deposit (FTD). The seller carries more risk, so access is narrower and prices higher.
On the other side of the deal, offers pay affiliates in CPA, RevShare or Hybrid models. The choice between them changes cash flow and risk for a buyer who pays for clicks up front, so check the model before you launch.
Among the 66 ad networks in the CPA GURU catalog with a recorded pricing model, 82% list CPC, 80% CPM and 48% CPA (as of 31 October 2026). Most networks offer more than one model, so the shares add up to more than 100%.
Where do media buyers get traffic?
Traffic sources fall into a handful of families. Each has a different audience, price level and policy position on gambling-related offers.
- Ad networks sell several formats through a self-serve dashboard. You can compare them in our ad network directory. Among 67 ad networks with listed formats, 67% offer native ads, 64% push, 63% pop formats, 58% banners and 46% video (as of 31 October 2026, in the CPA GURU catalog).
- Social platforms offer detailed targeting and creative-led campaigns, but with strict advertising policies and a higher risk of account restrictions.
- Search and display advertising: search captures existing intent and display extends reach, but both apply their strictest rules to restricted categories such as gambling.
- In-app and mobile traffic is bought through app-focused networks and supply platforms.
- Direct deals with publishers and communities need negotiation and trust but can give stable, less contested placements.
An offer’s own terms come first. Programs and networks list which traffic types are allowed and which are banned, and breaking those terms can mean unpaid conversions or a closed account. Among 264 CPA networks with traffic rules recorded, 66% accept Facebook ads, 62% accept SEO traffic, 57% accept PPC and 36% accept push (as of 31 October 2026, in the CPA GURU catalog). Always read the specific program’s terms on the program’s website rather than assuming a source is allowed.
Which tools does a media buyer need?
A working set has a few core parts and several optional ones.
- Tracker. The central tool. It records clicks, passes the click ID to the offer, receives postbacks with conversions and shows spend, revenue and ROI by source, creative, landing page and GEO. Without it, optimisation is guesswork. Browse the tracker directory.
- Spy services. These show creatives, landing pages and offers that other advertisers are running, which speeds up idea generation and offer research. They show what is being run, not what is profitable. See spy services in the catalog.
- Antidetect browsers and proxies. Teams that manage many ad accounts use them to keep browser profiles and connection data separate and organised.
- Cloakers and traffic filters. These screen out bots and invalid clicks before they reach a page. Ad platforms prohibit showing their reviewers different content from what users see, so check platform policies and local law before using any of them.
- Payment methods. Ad networks and platforms need a funding method, so payment tools form a practical part of the stack.
As of 31 October 2026, the CPA GURU catalog lists 42 trackers, 33 spy services, 43 antidetect browsers and 27 cloakers. Start with the tracker: it is the one tool every other decision depends on.
Which metrics matter in media buying?
A handful of numbers explain almost any campaign. Learn their formulas first, then compare them across sources.
- CPC (cost per click): spend divided by clicks. What each visit costs.
- CR (conversion rate): conversions divided by clicks, or by landing page visits. How well the funnel turns visits into actions.
- EPC (earnings per click): revenue divided by clicks. What each visit earns you.
- CPA (cost per acquisition): spend divided by conversions. What each target action costs you.
- ROI (return on investment): revenue minus spend, divided by spend. Positive means the campaign earns more than it costs.
A campaign covers its advertising cost when EPC is higher than CPC, or equivalently when the payout per action is higher than CPA; full profitability also requires revenue to exceed other campaign costs, such as tools, proxies, creatives and team time. A further caveat is timing: the offer’s approval process, hold period and payout schedule mean that revenue in your tracker is not yet cash. Among 301 CPA networks with a recorded minimum payout, the median is $100 or €100, and among 46 ad networks with one, the median is $50 or €50 (as of 31 October 2026, in the CPA GURU catalog). Among 339 CPA networks with a recorded payout frequency, 30% pay once a month and 24% once a week.
Negative carryover matters too. Under this rule, a negative balance (a period in which referred players won more than they lost) is carried forward and deducted from future earnings. Of 2,786 affiliate programs with this field recorded, 433 apply negative carryover (as of 31 October 2026, in the CPA GURU catalog). A buyer who pays for traffic up front should know which side of that line the offer is on.
How do media buying teams work?
Many media buyers start alone, but larger operations split the work. A typical team has:
- Media buyers, who run campaigns and own the numbers;
- Team leads or heads of buying, who set budgets, choose sources and verticals, and review results;
- Creative specialists, such as designers and video editors, who produce ad materials continuously because creatives wear out;
- Tech specialists, who set up trackers, domains, landing pages and account infrastructure;
- Analysts, who reconcile data and find the weak spots;
- Affiliate managers on the program side, who agree terms, caps and payout conditions.
If you want to hire a team or see how existing teams present themselves, the media buying teams directory lists them.
What affects how much a media buyer earns?
There is no honest single answer, because earnings depend on how the buyer is paid and on the campaigns themselves. These factors matter most:
- Employment model. A salaried buyer in a company, a buyer with a revenue share on results and an independent buyer spending their own budget have very different risk and income profiles.
- Experience and track record. A buyer who has taken campaigns through testing to stable profit on several sources is a different hire from a beginner.
- Managed budget. Larger budgets generally mean more responsibility and higher rewards, and larger losses when tests fail.
- Vertical and GEO. Payouts, competition and traffic costs vary widely by vertical and country.
- Costs and payout terms. Tools, creatives, accounts and delayed payouts all reduce what is left after revenue.
Treat any income figure you see without these details with caution.
How do you start in media buying?
A sensible path for a beginner looks like this:
- Learn the vocabulary: payout models, traffic types, the metrics above.
- Read how an offer’s program works and what its terms allow, using the catalog’s program pages as a starting point.
- Pick one traffic source and one format and learn them properly before adding more.
- Set up a tracker before spending anything.
- Fix a test budget and a stop-loss in advance, so a failed test is a lesson rather than a crisis.
