Indexing faster in Google is all about letting Google know that you have launched the website. As fast you invite Google in opening ceremony of your website that fast your website will get indexed in Google.
Now question is on which address you should send invitation card for the ceremony? You should send where Google visits very frequently. By doing this Google bot will come across your newly launched website link and it will crawl and index it in very less time.
You can use signature links of forums like Digital Point where Google crawls very very frequently. So you can change your signature link to your new website and then create a new topic. A new topic will be crawled by Google in 30 minutes or so and with that your new website too.
So you will get listed in Google usually within a day for free. Happy Indexing !
