I have a new blogger blog and I did not yet make any kind of promotion. I try to search it in google with the full blog address i.e. blog.blogspot.com. But google could not find it. Please tell me why, google can not find my blog? When google could find my blog?
Exactly, give it time to get indexed and then start promoting it. These things kind of take time, weeks for that matter.
Use Google webmaster tool and submit site map like atom.xml. Then submit your site to Google using this link http://www.google.com/addurl/?continue=/addurl. Then share your site to several popular social networking sites. Hope you will get indexed your site very soon.
Does the site have any content already? If it is a new blogger blog, then you should not worry as it will surely come up in Google, unless you have really done something wrong.
Most probably your blog has not yet indexed by google, create more links to your blog and ping it regularly.
get backlinks of competitor blogs and submit blog on those site..it will up hopefully, focus high PR blog submission directories.
submit your blog in blog directories and blog pinging sites. Also perform Social bookmarking of the blog. This will help in easy indexing of your blog.
your blog is not index by google till now, you just post on regular basis and try to ping your blog post in few days your blog will get indexed
