Hello Anirudh,

Firstly, is the author info area disabled? If it is disabled, Google will not be able to find the author tag. The author info should be available in the author area below the blog post when you are viewing the full blog post.

If it is already enabled, ensure that you setup the authorship correctly here, https://plus.google.com/authorship

Firstly, is the author info area disabled?

Hello Anirudh Kumar,

I have replied in this post thread -> http://stackideas.com/forums/author-metatag-not-visible
By the way, you can enable the option from your backend > Easyblog > setting > layout > general tab > User > Display author info
Hope this help.
