Google is no doubt the best source of traffic for a website. You must properly index your site in this great search engine. Generally Google itself index the new sites with its regular crawling system, but you must ensure all of your content is there in google's notice. First check if google has index your blog, just go to Google Webmaster Tools and check your site. If your site is not there then login for Google Webmaster Tools and click "add a site" and enter your site address. After you submit your site it will be index by google on next crawl.
After indexing you will be promoted to verify your ownership. You should verify I recommend this. You can verify your site either by adding a meta tag (easier method) to your site or by uploading a provided html file.
After verification next thing you do is share the complete sitemap with google, this is very critical for complete indexing. To submit your site map on your Google Webmaster Tools dashboard click your site, and then click "site configuration" (drop down menu) and then go to sitemap option and hit "Submit a Sitemap" button and put your sitemap url. I have described how to create sitemap in another post.
Once you have done this Google will crawl your site in a better way, and you will Google Webmaster Tools will provide you detailed stats about your site.
This will also help you improve page rank of your URLs
