How it works
- Inquiry — Tell us what you are promoting, which placements you want (or ask us to recommend), and your preferred dates.
- Quote & approval — We send a custom quote. Sponsored content must follow our sponsor rules. We may decline campaigns that are not a fit.
- Creative — You supply finished images in the sizes below, or ask us to produce assets.
- Go live — After payment and approval, your banner is scheduled for your campaign window.
Important: Sponsorship is brand exposure, not a performance guarantee. We do not promise clicks, conversions, or a minimum number of views.
Creator self-promo bundles are a separate product: creator promos.
Where your ad can appear
Each placement is a reserved slot on the site. When multiple sponsors share a slot, rotation is weighted — we confirm your share when quoting. Use View on page in the form to jump here and see where each slot sits.
Mini layouts — highlighted slot matches your form selection when you use View on page.

Creative production by Inkstra
We can produce a simple static banner from your logo, art, and copy. Production is a paid add-on (markup on top of the sponsorship quote), agreed before you approve.
