There is no surefire way to get backlinks crawled faster and i asure you 99 percent of things you may try will cause problems, why beacuse this is not natural indexing of links to your site, this is you trying to force google and google may see it as spam links. The older your site , gets the more trust it build, having good content and getting links from qaulity websites all effect how often google crawls your site and whomever points to it. If you wnat to be in business for a few months try some pinging site get your site banned and be forever on the backfoot with google, IF you waith that same period of time growing your traffic and not forcing google , you will have a better standing with google and a much stronger site. Most guys oon page one and two are playing the long game, there no point in trying to force your way in.
