Advertise on CliffMap
Reach developers at the moment they ask where a free tier ends and what the next step costs. Prices are public, a sponsored card is always labelled, and it never moves a number or a chart.
Status: waitlist only. Payments are pending approval with our payment provider, so nothing on this page can be bought yet. Join the waitlist and we will write to you before sales open. Until then no card is taken and no click is sold. The first 20 vendors on this site get 30 days of sponsorship free, with no card, then decide.

How clicks are counted and delivered
- What counts: a click on your sponsored listing that leaves CliffMap for your own website, through our counting redirect (
/out/<vendor>-<slot>). - De-duplication: one valid click per visitor per 24 hours, identified by a salted hash of IP address and browser string. The salt changes daily and the hash is discarded after 24 hours.
- Not counted: known bots and crawlers, your own staff clicks if you tell us your IPs, and repeat clicks within 24 hours.
- Delivery: clicks are not guaranteed. Your slot or pack is shown on the pages you bought; clicks arrive as readers choose to click. A pack is “delivered” when its clicks have been counted. You see impressions and valid clicks in a public statistics page and a monthly email report.
- Status today: the counting redirect and public statistics page are built and tested before the first paid slot starts. Until then we do not sell clicks.
How sponsored placements are labelled
- Every paid placement sits in its own block marked Sponsored and is never mixed into the ranked tables, charts or calculator results.
- Sponsored links carry
rel="sponsored nofollow". We do not sell dofollow links. - Sponsored cards never change a chart, a total or an order. A configuration change that only affects sponsors is not allowed to change ordering or any calculated number.
- Sponsors cannot edit, hide or delay a price, a source or a correction. Corrections are free for everyone and handled within 7 days.
- Read the full policy on How we make money.
Refunds and cancellation, in short
- Click shortfall: if your slot gets fewer than 15 valid clicks in its first 30 days, We check the count at the end of the first 30 days and email you the result. We either refund that month promptly after the check or credit the next month free, as you prefer.
- Monthly subscriptions renew automatically each month at the price shown here until you cancel. Cancel any time by emailing contact@clioos.com or with the link in your receipt; it ends at the close of the paid period.
- Full wording: Refund & Cancellation and Terms of Service. Payments will use a third-party hosted checkout; this site never sees card numbers.
