Free Mass Ping Unlimited Websites or Blogs or RSS on BulkPing.com
Bulk Ping is a mass pinging service that attracts search engines to the entered web site. Do this for new content on a site or for new websites. Attracting the search engines first gets your pages spider-ed and then hopefully indexed, so that your web pages are on the virtual tip-of-their-tongue of the search engines. Single web page pinging is supported as well.
This site will also submit RSS feeds and ping them. RSS submission is to twenty-seven different rss engines and rss directories using over 2000 randomized proxies. The benefit of this is better acceptance of rss feeds and subsequent indexing.
