Your blog is still very new. So it has not been indexed by Google and of course it has no Google PR.
What does Indexing mean?
It simply means a record of your website contents in the database of a search engine. Many times it refers to Google recognizing that your website exist.
When any of your webpage is indexed, it will be listed during a search for a relevant content by anyone using the search engine. For example, if you conduct a search for Nigerian Entrepreneur, all my website pages that have been indexed for the keywords will be listed alongside that of other websites.
Do you have one page?
No. You misunderstood the information in the letter. They did not say you have one page. They are simply informing you that none of your website pages can be found using a search engine. You can actually try this yourself. Pick the most popular article you have on your site. Use the exact words you have as the title in a search engine (I recommend Google) and click search. If your website is listed among the result, then it means that the page has been indexed. If not, it means it has not been indexed and as far as Google and the other search engines are concerned it does not exist.
I will be willing to provide you will further information if only you ask. Cheers.
You can hasten the indexing of your blog by requesting your friends who have Google PR1 or more to post a link on their website pointing to your website. That way, you will be index fast.
