How to recover your deleted
blogger post
1. Using Google Cached Pages.
If your blog isn’t pretty young
and you have your posts
indexed on google search
engine, then this method is for
you.
Simply visit ‘www.google.com’ ,
now in the search box, type in
‘site:yourdomain.com’ . Replace
‘yourdomain.com’ with your
domain. For instance, this blog
would be ‘site:oscarmini.com’ ,
then hit the search button.
The indexed posts would
appear, now scroll down to any,
below the link, click on the
Cached link.
After clicking the Cached link,
the post would appear, now you
can copy the post title and
content, login to your blogger
dashboard and make the blog
post again. The permalinks and
social shares would remain
same.
If your blog has not been
indexed by Google Search
Engine, then the second method
is for you.
2. Using Feeds
This method requires that you
subscribed to you blogs feeds by
email.
Simply log in to the mail you
used in subscribing for the
feeds, search for all mails from
your feed.
Now you do have a backup copy
of your posts. You can copy it.
Log in to your blogger
dashboard, create a new post,
then paste the copied post as a
new post, but with same title so
as to retain the permalinks.
