A have a PR4 blogspot.com blog - but recently I placed it as a private blog, so I am the only one who can have access to it. Can other blogs still enjoy backlinks from this private blog of mine?
If Your blog posts don't show up on a google search then your outgoing links for that page isn't doing anything for those websites.
Hello! it is good that everybody can access your blog so that people can read your content also you'll share what is in your mind. I write my blog for purpose because I want to help others concerns and solve some people's problem.\ I don't know your reasons. it is your decision to placed in private. Thanks.
if no one cann access the blog without logging in, then there will be no seo benefit for anyone that are being linked to. you can edit your meta robot tag to allow access for googlebot which way googlebot can visit your site and index your pages. this way your site can pass link juice
