Publishers offering "Widget Ad" spots

A widget ad is a sponsored box inside a small tool that other sites embed, such as a live scores widget or a music player. Cricwaves, Mixcloud and the Philippine Daily Inquirer sell versions of it.

How it's sold: You book it directly with the publisher's sales team. Four publishers list it today, all on the web.
What it costs: Most publishers quote this on request, and it is commonly a flat fee per month.
What you supply: You supply a logo, a short line of copy and a link, and sometimes a banner image.
Best for: It suits you if you want your brand to travel with a tool that people use again and again.
Before you buy: Ask where the widget is embedded and how many people see it, since it can run on many sites.
