ok this is what you do: sign up for a google account, sign up for google webmaster tools, once you have your account click add site and add your site. sometimes it takes google awhile to crawl your site but it will eventually so be patient. also in the future if you have a website thats pretty good size id submit your sitemap to them. but if its just a regular blogger blog or something then id skip that. anyways once your site is crawled it should show your backlinks and how many you have.
