Making a blog searchable is the first step in getting search traffic, and readers, for our blogs - when we want them visible to the public. Not all blog owners want their blogs visible to everybody. Complementing the ability to publish a blog, and have it visible only to invited readers, Blogger gives us the ability to make the blog invisible, to the search engines. If we want readers for a blog, and do not have a private reader audience in mind, we first make it visible to the search engines.
