OIO Publisher is a php ad management script that can also be used as a WordPress plugin, giving you complete control of your website’s ad space.
A single license can be used on all of your websites, making it one of the more cost-effective Google AdSense alternatives.
Once you’ve set it up, OIO automates the bulk of the selling process. You can also search the OIO ad marketplace and reach out to advertisers. This allows you to negotiate directly with them and build ongoing relationships.
To get the most out of the tool, you need to be quite proactive to find the best advertisers and deals.
However, there’s no middleman commission, so you keep 100% of the revenue, and you receive upfront payment instead of waiting for payouts, so the effort is well worth it.
