I have searched high and low for an answer to this:
How do I link my Google+ account to a free wordpress.com account?
Google+ asks me to do this:
By adding a short line of code to http://alexmarshallguitarlessons.wordpress.com/, you can make your Google+ page eligible to show up on the right-hand side of the Google search page for relevant queries and make your Google+ page more discoverable. Learn more
Ask your site's webmaster to add the following line of code to your site's homepage:
You can also email these instructions to your webmaster
I have pasted this code into the text on my homepage, but when I 'Test website' from Google+ I get this error message:
"Check that the line of code has been added to your site's homepage and that the modified homepage is live on your site. Then try testing again."
I feel like I have achieved this for another free wordpress blog, but can't make it work.
The blog I need help with is alexmarshallguitarlessons.wordpress.com.
