For product owners
Promote Calculator Campus
Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Calculator Campus in front of people instead.
- Back in the X and Threads rotation: Calculator Campus gets posted again instead of once.
- A promoted slot on the AppRater homepage, carrying a Promoted badge.
- A direct link to Calculator Campus from a DR41 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.
