Because your blog is new and has only one post. Search engines are in the business of directing people to things they want to read; the more original information on the site, the faster it gets ranked. Simply blog more and it’ll happen.
Thanks for that. But that doesn’t explain why, when I input my exact blog address into a search engine, e.g. Google, it doesn’t find my blog! Why the heck is that? I literally can’t find it ‘public facing’ anywhere, so feel like I am talking to myself.
Yes, it does explain it. As far as search engines are concerned, your blog doesn’t exist. Until you have more content and/or incoming links from other people who think your stuff is good enough to link to, you will remain invisible to them.
