Blogs already have a number of services dedicated to indexing and searching their content, now Google has got into the game itself. Google Blog Search is still in beta, but I’ve just taken it for a test spin and it seems pretty fast.

Google blog search scans content posted to blogs and feeds in virtually real-time, according to Jason Goldman, Google product manager for blog search.

“We look for sites that update pinging services, and then we crawl in real-time so that we can serve up search results that are as fresh as we can,” said Goldman.

Google defines blogs as sites that use RSS and other structured feeds and update content on a regular basis.

Google is not offering any means of submitting a blog or feed to the new service. However, if you publish a feed and want to include it in Google blog search, the easiest way to make sure it’s included is to make sure your publishing system is set up to notify popular blog pingservers that are monitored by other blog search services. The easiest way to do this is via pingomatic, which can ping more than a dozen popular pingservers, according to Goldman.

If you ever needed a reason to ping the update servers when you actually update your blog, now you have one. If you’re looking for a way to exploit this for spam purposes, please don’t - you’ll only ruin a good thing.
