Publishers offering "Floating Ad" spots

A floating ad is a small card or widget that stays on screen while the reader scrolls, usually in a corner. Pinpoll runs one inside its widget and SHE.com sells a sitewide floating card.

How it's sold: You book it with the publisher's sales team, and it usually runs for a set period across the whole site.
What it costs: Most publishers quote it on request, and a flat fee per week or month is the usual basis.
What you supply: You supply a compact image or short copy with a logo, and a landing link.
Best for: It suits steady visibility and clicks on a single offer.
Before you buy: Check that it can be closed and that it does not cover content on phones, since that affects both the reader and the click quality.
