You'll see result instantly as more new posts will be indexed faster, thereby bringing more visitors to your website. Although I'm not sure till how long Google will keep this feature up (by default it the crawl rate settings expire in 90 days.. which indicate that Googlebot might be indexing more websites than it was originally built to) but nonetheless, if you're constantly publishing articles to your website it can be a great help.
Step 1: Getting a Google Webmaster Tools AccountOkay, so in order to get started, the first thing you'll need is a Google Webmaster tools account. Getting one is as simple as it can be – simply head on over to the Google Webmaster Tools website and sign up for an account. Or if you already have a google account, simply sign into Webmaster tools.
Step 2: Add your website and Verify ItOn your dashboard, you'll see a textbox where you can add your website. Type in the URL for your website, and then click Add Site. Once you do that, it'll take you through the procedures to verify the website / blog that you've added to your account. Once you're all done it'll look something like this on your dashboard page:
Step 3: Tell Google / Googlebot to crawl your website faster!Okay, once you do all the above (well verifying the website does take some time though, so it might not be as quick as you expected it to be). You can then tell Google to index your website faster. To do so, click on your blog/website in dashboard, till you get to the Overview Window. Then on the left hand side, click on "Tools" in the menu and then click on "Set Crawl Rate".
Then, you can set your crawl rate to faster, to get Google to crawl your website much more faster.
Instant indexification! Not really, but better than the usual slow (this of course depends on how "popular" your website is) indexing by google.
