Want to see how many links your site is getting from Yahoo! Search? Try out the new Site Explorer Badge, just pushed live today from Yahoo! Search. The Site Explorer badge queries the Inlink Data method of the Site Explorer API, wraps the result in a callback, and shows it inline on your site, without requiring any extra bandwidth from your server. The example code is short and sweet, and provides an excellent Hello World example for those who are just getting started in the wonderful world of badge design.
