Google controls more than half of Internet traffic. Most people rely on Google services especially Google Search, image search and Youtube to find the stuff they need. This is why Google is very important for every blogger. The organic traffic from Google is the single most important source of traffic for every blogger.
If you have just started your own blog and have done everything right, it will take a few days or even a few weeks for Google to find and index your blog posts. Most bloggers create an account in Google Webmaster Tools and submit the sitemaps in order for Google to find their blogs quickly.
But the fact is that Google will only start crawling the pages until it sees some links pointing to your blog. So you will need to write something that gets attracted by some established sites and they link back to you in recognition. Otherwise, you may want to build links by yourself by guest posting on reputable sites in your niche.
Another easier method to get your blog indexed immediately by Google is the Fetch as Google function. This tool allows the user to fetch a URL as Google bot. This makes sure that Google can access, crawl and index your site.
Fetch as Google returns the following information:
The HTTP response returned by your server
The date and time of your crawl request
