Another easy way is to just tweet it, which works for me - they usually get indexed < 1 hour later. Google has access to tweets and the URLs in those tweets.

Probably some sort of crawling. When Twitter became shortly logged-in only, google could not display tweets in search anymore.

No Paid.. just simply tweet it from a regular twitter account
