Recent detections in Marketplaces

  • copy PoshmarkJun 25, 2026

    Visit 5 (Chrome) shows 'MOST SEARCHED BRANDS THIS WEEK' with different brand listings (Coach, Louis Vuitton, Nike, Lululemon Athletica, Chanel, Michael Kors), while visits 1, 3, and 4 show 'MOST LISTED BRANDS THIS WEEK' with different brands (Lululemon Athletica, Free People, Nike, Louis Vuitton, Zara, Anthropologie). The section headline copy and brand content differ. Visit 2 (Chrome) appears to be a partial/broken render showing a completely different layout.

  • hero UpworkJun 25, 2026

    Visit 2 (Chrome, first crawl) shows a distinctly different hero section with headline 'Connecting businesses in need to freelancers who deliver', a different hero image (woman with glasses), different CTA buttons ('Find talent' / 'Browse jobs'), different search bar placeholder, different logo strip, and a simplified pricing section labeled 'Clients only pay after hiring' with fewer feature bullets. Visits 1, 3, 4, and 5 all show 'Work at the speed of your ambition' hero with AI-amplifier subhead, 'I want to hire / I want to work' toggle, and a fuller pricing section. The divergence is isolated to visit 2, which uses a different VWO UUID, confirming a real experiment bucket assignment rather than a browser rendering difference.

  • form FaireJun 13, 2026

    Two distinct signup form variants are present. The control (visits 1 and 5, Safari and Chrome) shows a single-step form with headline 'Sign up to sell on Faire.' and fields for Brand name, Email, Website, Country of tax residence, wholesale product count, store count, and Primary category, with a 'Sign up' CTA. The variant (visits 2, 3, and 4 — Chrome, Firefox, and Edge) shows a multi-step form with headline 'Welcome! Sign up to sell on Faire.' and fields for First name, Last name, Business email, Phone number, and Password, plus a marketing opt-in checkbox, with a 'Next' CTA.

  • hero AirbnbMay 14, 2026

    The hero headline differs across visits: Safari shows 'Your home could make $1,092' (a specific earnings estimate), Chrome shows 'Your home could make $ during the FIFA World Cup 2026™' (an event-specific promotional variant), and Firefox shows 'Your home could make $1,008 on Airbnb' (a different earnings estimate with map visible). The Chrome visit is the only one showing the FIFA World Cup copy, which differs meaningfully in messaging strategy.

  • navigation The RealRealMay 13, 2026

    Visit 2 (Chrome) shows a different navigation item: 'Get an Estimate NEW' (with a green 'NEW' badge) replacing 'How We Price' seen in visits 1 (Safari) and 3 (Firefox). The EXP_beed972e0b localStorage key diverged between visits, confirming bucket assignment differs. Since only the Chrome visit shows the different nav item while Safari and Firefox share the same nav, this appears to be a Chrome-only divergence. However, the experiment cookie diverged, suggesting this is tied to experiment assignment rather than browser rendering.
