Index sites online
 

Here is an easy and absolutely free trick you can use to get your new blog indexed by Yahoo and Bing. Believe it or not, but these two search engine behemoths (and not just them) will almost instantly (sometimes within 48 hours or less) index your blog the second one of your visitors includes your blog RSS feed in their search engine specific account. For instance, Yahoo will spider your RSS feed and blog when a visitor of yours will include your feed into their personal Yahoo account. Once that happens, Yahoo will do this within 48 hours - an amazingly short time for such a fit, wouldn't you agree?

Is there a similar trick for Google. In my opinion the only method there is to get a backlink from high PR website.

Ya i think there is no trick for google just work honestly
