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 in the form. 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 highlight a slot.

Mini layouts — highlighted slot matches your form selection when you use View on page.
