If you are having trouble getting a specific page or even en entire website indexed by Google, try these two steps:
1. Try bringing the site or page up in the Chrome browser. According to some people working at the big G, Chrome works as a pinging utility for Google.
2. Post a backlink to your site on Orkut.com This is a Google owned microblogging platform. But you aren’t limited to just 140 characters like you are on Twitter, and you can even use html and embed codes. All of Orkut.com’s pages carry a PR of 8, Your Kung Fu will be strong with this one…
