Advertising, clearly labeled.
Paid placements help support the directory. They are separate from organic search results.
How to recognize an ad
Every paid banner is marked Advertisement and identifies its advertiser. Ads do not change organic ranking. We do not use search terms to target ads, and we do not send searches to advertisers. Empty development placeholders are not advertisements or study recommendations.
Standards for advertisers
Before publication, we review advertiser identity, the study destination, and proposed claims. We reject misleading enrollment guarantees, unsupported treatment claims, fake endorsements, and deceptive formatting. Advertisers must supply accurate, current information and any recruitment approvals required for their study. Review does not establish trial suitability or guarantee results.
External destinations
Clicking an ad opens the advertiser’s destination, where separate privacy practices apply. We do not place tracking pixels or behavioral advertising scripts on the directory. Financial relationships must be disclosed prominently at the placement.
