Frequently asked questions
How the exchange works, in plain terms.
What's the difference between barter and cash?
A barter group shows other members' banners to earn credit, then spends
that credit having its own banners shown elsewhere. No money moves. A cash
group runs its own banners on its own pages and pays for the placements.
How do I add a banner to my site?
Create an ad group, and you'll get an account number and a snippet. Paste the snippet
where you want the banner. The id on the div is your account number and the
banner size joined by a hyphen.
Can I run more than one banner on a page?
Yes. Each slot is addressed independently, so a sidebar unit and a leaderboard can sit on
the same page. Give each one its own div and its own ovsShow call.
Why isn't my new banner showing?
New banners are pending until an admin approves them, and they never serve
before that. Check the size in the snippet matches the size on the banner, too — a
mismatch renders nothing.
What do I control about what appears on my pages?
Barter groups pick the categories they'll accept. Banners outside your list are never
eligible for your pages. Every banner has also been reviewed by a person before it can
serve anywhere.
What happens if vieworo is down?
The snippet gives up after five seconds and draws a neutral placeholder at the right size.
It won't collapse your layout or throw errors into your visitors' consoles.
