How clinical trial sponsors and recruiters can advertise on Reddit: approval, licenses and cost

What counts

Reddit treats these as restricted.

Patient recruitment for sponsored trials
Research sites and site networks
Recruitment firms working for sponsors
Registries and pre-screening for studies

Which vertical you are in is settled at step one: banking, insurance, credit, investment and crypto; real-money gambling and lotteries; prescription drugs, telemedicine, devices, pharmacies and clinical trials. Some adjacent products, like basic supplements, fall outside all of this and buy Reddit ads the ordinary way.

Getting verified

How clinical trial sponsors and recruiters get approved, step by step.

Nothing here is a favour or a shortcut. It is the route Reddit provides for licensed advertisers, and it is mostly paperwork done in the right order. The first two steps cost you nothing.

1ApplyTwo minutes: your vertical, the markets you want, the licenses you already hold, and your site. No license numbers and no documents at this stage.
2We pre-check you against the license mapFor each market you named, we check the regulator Reddit verifies against and tell you which markets are open to you now, which need a license you do not yet hold, and which are closed whatever you hold. Most applications get that answer within three business days, with a free audit of the opportunity attached. If nothing is open for you, we say so and you have spent nothing.
3You fill in the document packA short set of forms: legal entity details, the license number and issuing regulator for each market, the landing pages the ads would point to, and the creative you have in mind. A few products, NFTs and some crypto offers among them, add Reddit's own diligence questionnaire.
4Vertical approval with Reddit's agency teamThe pack goes to Reddit's agency team, who run the vertical approval alongside the account setup. That review is theirs and so is its timing. We submit it, chase it, and tell you where it stands each week.
5The managed account opensCampaigns run on a managed agency account alongside Reddit's agency team. That is the account type these verticals are approved on, and it is the part most advertisers cannot arrange for themselves.
6Creative written to the vertical's rulesNo guaranteed returns, no approval promises, no health outcome claims. Every ad is checked against the vertical's rules before it is submitted, so review is a formality rather than a round of rejections.
7Track and report as usualReddit Pixel and Conversions API, qualified leads, and a weekly scorecard. Approved does not mean unmeasured.

What gets checked

What Reddit and the regulators look for.

Registration and ethics approvalThe study registered where required, for example with the NIH in the US, the NIHR in the UK or the DRKS in Germany, and the recruitment materials approved by the ethics committee or IRB that oversees the study.
The approved wordingAds use the wording the ethics committee approved. A new headline is a new submission, so creative variants are planned up front.
No inducement or promiseNo promise of benefit or cure, and compensation described only as the approved materials describe it.

What it costs

Free to find out. A fixed fee to run.

The pre-check and the auditFree. The license verdict for your markets within three business days for most applications, and the audit of the opportunity when a market is open. No commitment at the end.
Ad spendBilled to you by Reddit directly, at the budget you choose. The audit shows Reddit's own delivery estimates at three budgets, including the smallest one that still lets a campaign learn.
Running itA fixed fee for a fixed scope, written down after the audit and before any work starts. Never hourly. At higher spend levels, campaign management can be included.
Your licensesYou hold them already or you do not; nobody can buy them for you. The pre-check tells you which ones matter for the markets you want.

Campaigns run on a managed agency account alongside Reddit's agency team, who handle the vertical approval with the account setup, targeting and optimisation. You keep full visibility of spend and results, and the ad spend is billed to you by Reddit.

Worth it?

The Reddit opportunity for clinical trial recruitment.

Where your buyers talk on Reddit, and what to say →

Start here

Apply for the pre-check. The audit comes with it, free.

The pre-check answers one question: given your licenses and the markets you sell in, can you run Reddit ads at all, and where. We answer that within three business days for most applications. When the answer is yes, an audit of the opportunity comes with it, built the way we build them for paying clients, with Reddit's agency team. There is no fee for either and no commitment at the end of them.

What the audit includes

The license verdict, market by market. Which of your products fall in a restricted vertical, which markets are open to you today, which regulator Reddit would check, and what is missing.
A community map. The subreddits your buyers are actually in, with deduplicated reach and screenviews for the last 30 days, from Reddit's own planner rather than our guess.
Keyword and interest targeting. The search terms and interest categories, grouped the way the campaign would use them.
A campaign structure. Objective, geo, flight, and which single conversion the campaign should optimise toward, with the reasoning for choosing that one over the more valuable but rarer action.
Three spend scenarios. Reddit's own delivery estimates at each budget: impressions, clicks and conversions, including the smallest spend that can still learn anything.
Benchmarks for your category. CPM, CTR, CPC and CPA from recent auction activity, marked clearly as planning benchmarks and not promises.
A measurement plan. The conversion events to fire, the Pixel and Conversions API setup, and the CRM field that decides whether the test worked.
Four creative directions. Written headlines, body copy and calls to action for each, mocked up as real Reddit ads.
Success criteria and one decision metric. What good looks like at day 30, and the single number you judge it on.

About a week from a complete application, and it is yours whether or not you work with us.

Questions this answers

What people ask before they call.

Can clinical trials recruit patients through Reddit ads?

In twelve listed countries, yes, through a managed account, with the study registered where required and the recruitment materials approved by the ethics committee or IRB. The ads use the approved wording, so variants are planned with the approval in mind.

Why do trial recruitment ads need ethics approval?

Because recruitment materials are part of the study, and the committee overseeing it approves what participants are told. That applies on Reddit like anywhere else. We plan the variants before submission, so testing does not mean going back for approval each time.

Can recruitment firms advertise trials on Reddit for sponsors?

Yes, on behalf of a sponsor, with the study's registration and approved materials, and with the approvals Reddit requires for the market. The pre-check confirms the markets and the study details before anything is built.
