I used to visit google webmaster tools for checking error related to my blog. Update new theme, changing hosting, domain propagation sometime went bad after sometime. Google webmaster tools is my friend to detect such error.
When I log in to google webmaster tools I found “exclamation mark” next to “search appearance” of this domain.
Further click lead me to structured data error.
Wow, 191 item with error.
Click the number give me ore detail error about blog post that affected with that error.
Further check using richsnippets tools give me exact error.
Its seem that I only need to fix ‘updated’ error section. Raymondware give great explanation about other error that might encounter.
Login to wordpress admin page :
1. Click Appearance -> Editor
By default you need to look for single.php and see the content.
Looking for ‘date’ section and wrap it with class “post-date-updated”. Unfortunately in my case ( I use Emphaino theme) I must digging more to find relevant php file that contain the target. Its in ‘content-single.php”.
<?php emphaino_posted_on(); ?>
<span class=”post-date updated”><?php emphaino_posted_on(); ?></span>
Save and retry look it up from richsnippet tools.
The error is gone now 🙂
