Looking for a great way to attract those search engines to index and rank your site? Check out these WordPress plugins to help you spread the word about your blog.

Google XML Sitemaps
This nifty little plugin will allow you to index your blog to create a sitemaps.org-compliant sitemap of your WordPress blog – most importantly, this sitemap is supported by Google, MSN Search and Yahoo!. While it doesn’t create a physical sitemap page, it traverses your blog’s content and automatically builds an XML report that search engines can easily digest. Our only complaint? It slooooows the site’s administration down when saving posts, due the sitemap being rebuilt.
