Why is my blog not listed by Google? You'd think that Blogger and Google would work together! Every non Blogger blog that I have is automatically indexed - why not Blogger blogs??!!and
Why is my private blog indexed in Google? I don't want strangers reading my blog, certainly not from finding it listed in Google!!Both are valid concerns - and nether will ever be answered, unilaterally.
We are permitted to publish our blogs, anonymously. Major world events - such as the Iranian revolution in the first decade of 2000 - legendarily were enabled by use of anonymous Internet resources, such as Blogger blogs. However, true anonymity is extremely difficult to guarantee - and simply won't happen without a lot of planning, starting before we "Create a blog".
On the other hand, most people who publish a Blogger blog want the blog indexed by the search engines. But this won't happen, either, without a lot of work. If anonymity is to be an option, automatic search engine indexing cannot be possible.
All that aside, note that the terms anonymity, obscurity, and privacy are three different goals. None of the three are guaranteed - and none of the three, even if achieved, will guarantee either of the other two.
It's a dual edged sword here, folks. We all have to compromise. Neither true anonymity, nor true visibility, can ever be had, without hard work, planning, and persistent maintenance of any identities used, as blog owners.
