Private blog posts and their uses

Hello

I have a question about publishing private blog posts. For example, if you want to add a substantial amount of text content to your blog (for the use of keywords and establishing your niche) but that format isn’t appropriate for your target audience (e.g. teenagers who want pictures, videos). Do google readers still pick up on the information in there and count it towards page rank?

Private means personal and it is not visible to Google readers and not able to pick up information and may it does not count toward page rank.

If you can’t see the content without logging in then neither can Google.

Any content that is technically available but is in some way hidden from normal users is likely to get you penalised.
