WordPress announced that WordPress 5.3, coming next month will support Google’s UGC Nofollow attribute by default. Starting November 12, 2019, all links in the comments section will automatically use the UGC nofollow link attribute.
UGC Nofollow Attribute
Impact of Rel UGC to WordPress Sites
Any WordPress plugin that is involved with user generated content and links may have to update their code in order to support the new code.
The old callback:
has been deprecated in favor of a new callback:
The WordPress announcement did not specify if plugins using the old code would break the site or simply gracefully degrade.
Multi-Search Engine Compatibility
Google has indicated it will support rel=ugc. However other search engines have no indicated support for that code. In order to support all search engines, WordPress will output the UGC nofollow in a manner that supports all search engines.
This is the code:
Does Rel UGC Help WordPress Publishers?
There is no ranking benefit to the publisher for using the UGC nofollow attribute.
The UGC nofollow attribute benefits Google because it helps Google understand that a link was created by someone outside of the publisher’s control and that the link should not be trusted.
WordPress Code Deprecation
This change is important for WordPress developers because it involves a change to the code.
Here is how WordPress explains the change:
“In WordPress 5.3, wp_rel_nofollow_callback() will be deprecated in favor of more generic callback function, wp_rel_callback(), which is now used to add other rel attribute values to a specified link.
wp_rel_callback() is used by the existing wp_rel_nofollow() function to add a single “nofollow” value, and with the new wp_rel_ugc() function, developers can add both “nofollow” and “ugc” values to the rel attribute.”
And this is an example that WordPress shared on how to use the new code:
- Change to the rel nofollow link attribute goes into effect with WordPress 5.3 scheduled for November 12, 2019
- The change to the new UGC nofollow attribute will still work with other search engines
- Old nofollow callback has been deprecated
- The average WordPress user may not experience any inconvenience
