Publishers offering "Footer Ad" spots

A footer ad is a banner at the bottom of a web page, often 728x90 pixels. Readers see it after they finish the content.

How it's sold: Publishers like OPOKA, Ubuntupit and Newsroom Panama sell it, usually through their sales team or by email. A few offer it as a companion to other banners.
What it costs: The median published rate is 1,200 USD per month, based on three rates.
What you supply: You supply a banner in the stated size, and a link to your page.
Best for: It suits remarketing and low-cost reach, because readers who scroll to the bottom are engaged.
Before you buy: Ask how many readers actually scroll that far, since footer views are often much lower than headline numbers.
