A sticky sidebar ad is a banner that stays fixed in the side column as the reader scrolls down the page. It keeps your message on screen for the whole article.
How it's sold
Only a few publishers sell it, such as Bike Hub and Electrical Engineering Portal, and you book through their sales team. Expect to agree on dates and the pages it appears on.
What it costs
The median published rate is 109 USD per month, based on two rates.
What you supply
You supply a banner in the sidebar size, often 300x250 or 300x600, and a destination link.
Best for
It suits campaigns that need longer exposure on pages with long articles.
Before you buy
Ask for the average time on page, since a sticky ad only pays off when readers scroll.
