If your blog is newly made it wont show up at google yet at least wait for a month that's how it works.
Have you submitted your blogs to search engine? yes you need to put a little effort for your blog to show up on search engines.
There are three major search engines right now and it GOOGLE,YAHOO and MSN LIVE!.
Since GOOGLE is widely used. I will teach you how to submit your site on google to be indexed so that when you search your site it will come up.
1. Visit google webmaster here: CLICK HERE
2. Log in using your blog email and password.
3. add your site on Click Here to add your site.
4. verify your site. Choose meta tag as your verification method the code will look like this.

Do not close webmasters page.
5. In you blogger account go to Layout then EDIT HTML.
6. Paste your verification code above this "b:skin ![CDATA[/*". Save template.
7. Go to webmasters and Click verify button. Your done.
Wait for a week or two til your blog will be shown on google search engine. If you see a Not Indexed warning when you verify it, its ok it will be verified after a few weeks.
Your blog will now be shown to other people. But this does not mean that when people search for your tags it will come up at the number one spot. Most likely other blogs will be at number one. If you want to be at the number one use SEO search engine optimization.
