In some cases, you publish a blog to generate a feed. You want people (specific people) to read the feed, but you don't want the world at large to know about the blog. When you do that, there are two settings, in Settings - Basic, which will interest you.
- Add your blog to our listings? - If you select "No" your blog will not appear in the Blogger home page, Blogger Play, the "Next Blog" link, and similar places, but it will still be available on the Internet.
- Let search engines find your blog? - If you select "No", everyone can still view your blog but search engines will be instructed not to crawl it.
