Google has just made available its new blog search engine, becoming the first major search engine to offer full-blown blog and feed search capabilities.

“While Google web search has allowed you to limit results to popular blog file types such as RSS and XML in web search results for some time, and its news search includes some blogs as sources, Google hasn’t had a specialized tool to surface purely blog postings. In fact, while all of the major search engines have been dabbling with blog and feed search, none has done much with blog search until now. Google’s new service (in beta, naturally) is available both at google.com/blogsearch and search.blogger.com.“

But Google doesn’t provide any direct way to submit your own RSS feeds to it in order to be indexed. To make sure your blog RSS feed gets all of Google’s attention you need to use XML-RPC pings, and here’s more info on how you can do so.
