Promote Reaction Test Lab

Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Reaction Test Lab in front of people instead.

  • Back in the X and Threads rotation: Reaction Test Lab gets posted again instead of once.
  • A promoted slot on the AppRater homepage, carrying a Promoted badge.
  • A direct link to Reaction Test Lab from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
  • A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
  • Stays on the first screen however old the listing is, while new submissions push everything else down.
