I just happened to login to Lijit, a search widget for blogs, to check on my stats, and I noticed that they now offer a revenue share option.
The beta release of the Lijit Ad Network opened to advertisers and publishers today.
The advertising will be displayed in search results of blogs that opt-in to the Lijit Ad Network.
I haven’t seen a live example of the ads, yet, but I’ve applied as both an advertiser and publisher to give it a try.
It is not a requirement to run ads if you want to use Lijit. You can see an example of the widget on the left side of my blog.
In addition to displaying recent and popular searches on the blog, Lijit enables users to include links to their various social media accounts.
