What is an Arbitrageur?

An arbitrageur (also called a media buyer when the focus is ad purchasing) is a specialist who earns from the gap between the cost of ad traffic and revenue from monetizing that traffic through advertiser offers. The work centers on traffic arbitrage: buy on one side, convert and get paid on the other.

In Russian-speaking communities “арбитражник” often stresses the “buy low, monetize high” model (per conversion). A corporate media buyer may only promote an in-house product; an arbitrageur typically works with external offers and networks.

Typical responsibilities

• Pick vertical, GEO, and source to match offer terms.
• Build the funnel: creative → landing → offer; configure tracker and postback.
• Launch and run ad campaigns; control spend and bids.
• Analyze reports: ROI, CR, approval rate; cut losing segments.
• Work with an affiliate manager on caps, payout, and traffic quality.

Skills

Technical: tracker operation, URL parameters, pixel/CAPI, basic landing HTML/JS. Analytical: funnel reading, fast cost vs revenue checks. Creative: ad copy, designer briefs, format tests. Platform policy knowledge is critical — violations cause account bans and lost budget.

Soft skills matter too: negotiating payout bumps with network managers, reacting quickly to creative rejections, daily discipline reconciling numbers. One wrong postback parameter or click ID macro can hide profit for days until the chain break is found.

Organizational formats

Solo arbitrageur (alone or with outsourced creatives), team (buyer + creative + tech), agency across verticals. Larger teams split roles — buying, pre-landers, account farming, analytics — but the economic logic stays the same.

Entry paths include CPA network internships, freelancing on small budgets, or learning on self-funded test funnels. Experience in one vertical (e.g. nutra) does not always transfer to another (gambling): moderation, postback statuses, and traffic-quality expectations differ.

White, grey, and black hat

White hat — within platform and offer rules. Grey hat — aggressive creatives and borderline niches without explicit moderation bypass. Black hat — cloaking, fraud, policy circumvention; high short-term risk. “Arbitrageur” is not tied to a hat category — that describes methods, not the job title.

Tools

Ad cabinets, tracker, spy tools, spreadsheets, sometimes anti-detect browsers and proxies for multi-accounting. Tracker data quality determines whether profit is real or “painted” ROI from unmatched conversions and wrong cost.

Reporting breaks down by source, campaign, creative, GEO, device. Scale decisions need statistically meaningful samples — one day with two conversions is not enough to call a funnel profitable.
