When You Publish a New Post WordPress Automatically Notifies the Following Site Update Services?

When you publish a new post, WordPress automatically notifies the following site update services: Google Webmaster Tools, YouTube, and your blog’s own RSS feed. This allows you to keep your blog up-to-date with the latest changes and SEO improvements made to the other sites on your blog network.

WordPress also notifies the blog’s administrator if there are any updates or changes to the post that need to be made.
