For a while now we’ve had a system we’ve used internally to send messages to our users in the search sidebar. We’re able to tweet a link and have it appear in the sponsored section at the top of the sidebar.

Some partners such as OneRiot have also used this to get the word out about breaking news. Now we wanted to let any of our users take advantage of this ability to tweet out cool links and get them on Google, Yahoo and Bing straightaway. We hope people will use it to break news and advertise cool products.

You’ll need to pay $5 to get started with an account, but for the next couple of weeks, while we’re in beta, that will get you as many page impressions as we can serve – up to 300,000 per day though you’ll have to share that with other AdTweeters. In any case you won’t have to reload your account until we’ve shown at least 5,000 impressions of your text ad and link.

Here’s how to get started:

1) With WebMynd for Firefox installed go to:

2) Once you’ve confirmed your Twitter account, click on $5 to load up your account using Amazon payments.

3) From the Twitter account you registered, tweet out a link like this:

@_wm_publish 5000 Get your link here http://blog.webmynd.com

Obviously you can use your own text and link. 5000 is the number of impressions that you’re “buying” but remember you can pick any number and you won’t be charged for them for the next couple of weeks while the beta trial is running. You must include @_wm_publish though.

You can go back to the credits page to see the number of impressions that have been delivered, keep track of your AdTweets, and add funds to your account.

Please let us know how you get on!
