Senior Sourcing Specialist
A Senior Sourcing Specialist finds and vets offers and traffic sources for affiliate teams, negotiates terms with advertisers, and keeps a steady flow of launch-ready offers coming in.
What a Senior Sourcing Specialist does
A Senior Sourcing Specialist, or sourcer, makes sure the team gets working offers and traffic sources. In affiliate marketing, the offer largely determines whether a campaign is profitable, so sourcing is treated as a core function rather than a support role. In the nutra vertical, the sourcer also makes sure offers meet platform and regulatory requirements, because campaigns get blocked quickly otherwise.
Companies working in high-risk verticals need this role because the market changes fast: advertisers change their terms, platforms tighten their rules, and offers burn out. The sourcer continually updates the database of offers and sources so that arbitrage and media buying teams work with current data. The senior level means working independently with networks, direct advertisers, and partners without constant supervision.
A sourcer usually reports to the head of affiliate or the head of partnerships. In larger teams, the senior sourcer manages junior sourcers or coordinates their work. The role works closely with media buying teams, analysts, lawyers, and compliance managers who review creatives and landing pages.

By vertical
Nutra
In nutra, the sourcer works with supplements and health products, where claims and wording are the most tightly regulated. Offer evaluation includes checking the product, certificates, and platform block risks. Negotiations often center on high hold and refund requirements, which occur more often in nutra than in other verticals.
Levels
Senior
A senior sourcer independently conducts negotiations, is responsible for the quality of the entire offer and source base, and makes decisions about priorities and risks. They mentor junior colleagues and take part in choosing new GEOs and directions. Their responsibility for the team's overall results is greater than at the middle level.
How to get there
People usually move into sourcing from media buying, partner management, ad-tech sales, analytics, or arbitrage, where they worked with offers and traffic sources. Experience with affiliate networks, correspondence with advertisers, and an understanding of tracking are valuable. To enter nutra, it is important to know the advertising restrictions on supplements and health products on major platforms.
To prepare, learn affiliate metrics (EPC, CR, approval rate, hold), learn to read tracker reports, keep an offer database in a spreadsheet, and understand why offers get blocked. It helps to maintain your own list of offers with evaluations and record which ones worked and why.
Growth comes from expanding your scope of responsibility: from selecting offers for a single GEO to working across several directions, then to independent negotiations with large networks and advertisers. Moving to the senior level usually requires consistent results from the offers you pass along and the ability to work without constant oversight.

FAQ
How is a sourcer different from a media buyer?
A media buyer launches and optimizes ad campaigns, while a sourcer finds and vets the offers and traffic sources those campaigns use. Sourcers usually negotiate with advertisers and networks, while media buyers are responsible for results in the ad dashboards. The tasks overlap, so good sourcers work closely with media buyers.
Do you need medical knowledge to work in nutra?
Deep medical knowledge is not required, but it is important to understand which health claims are prohibited in advertising and why. A sourcer should be able to tell a platform-safe offer from a risky one and bring in lawyers or compliance in time. Basic knowledge of supplement ingredients and categories helps you evaluate products faster.
What determines a sourcer's income?
Income usually depends on the size of the team, the type of company (network, arbitrage team, or advertiser), the quality of the offers passed along, and the share of payouts that can be secured. For freelance or project work, reputation and portfolio matter. Exact figures depend on the market and the specific company.
What skills are needed to move into sourcing from another field?
Negotiation skills, analytics, the ability to work with spreadsheets and trackers, and an understanding of the affiliate model are important. Experience in sales, partner management, or media buying speeds up the transition. Nutra-specific knowledge can be built on the job by studying platform rules and real cases of blocks.
What does a sourcer usually check before launching an offer?
They check the product and its compliance with requirements, payout and hold terms, rejection and block history, GEO, and traffic requirements. They also look for terms that create risk for the team, such as unstable payouts or complicated refund conditions. The results are recorded in the offer database.
Can a sourcer work remotely?
Yes, most sourcing tasks are done online: correspondence, negotiations, and work with trackers and spreadsheets. Remote work is common in affiliate, but some companies require office presence or work in a specific time zone. Conditions depend on the employer.
