After researching on many
forums, I found that the ‘Page is not indexed: Redirect error’ issue is
because the new blogger crawls using ‘Googlebot Smartphone’ as the
default crawl, so every time a web link is opened using a phone or desktop, the
URL detected by Google's crawl engine is always the "?m=1" version.
To resolve the issue of Googlebot
indexing the mobile version with "?m=1" and ensure that it crawls and
indexes the correct desktop version of your pages.
I don’t know if this is a permanent solution
or not but working right now.
As per Google, to create a redirect
for a URL to help people find your blog on search engines
1. Sign in to Blogger.
2. In the top left, choose a blog.
3. From the menu on the left, click Settings.
4. Under "Errors and redirects," click
Custom redirects. Add.
5. Add the deleted URL and the URL you want to
redirect it to. If the original article was deleted, turn on Permanent.
6. Click OK. Save.
