Twitter links are no-followed, then how will Google index it?

Here are several ways to get index in Google and other search engines:

Search Engine Submission - submit only once
Ping your site -
Create quality of inbound links

I create social bookmarking links and forum signature links - but am afraid that sites often take 1 week to get indexed like this.

From my own experience I submit my blog in social bookmarking site and get indexed quickly within 24 hours. I'm sure that my first link is on social bookmarking so this could be the reason on why I get indexed quickly..

Google cannot ignore you for long when other popular websites take notice. Sometimes posting an ad on Craigslist can get you indexed within a few hours. You can also try using a social bookmarking service such as Digg or Del.ic.iou.us to create a link. Better yet, create a Wikipedia entry about your new product, website or service.
