How to Add nofollow to Specific or All Links in the_content

Are you looking for a way to add nofollow to specific or all links in the_content? While there’s probably a plugin for this, we have created a quick code snippet that you can use to add nofollow to specific or all links in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

function example_link_nofollow( $content ) {
	$url     ='http://example.com';
        $content = str_replace( '<a href="'.$url.'', '<a rel="nofollow" href="'.$url.'', $content );
	return $content;
}
add_filter('the_content','example_link_nofollow');

The above code will add nofollow to specific links with the URL mentioned above. To add nofollow to all links within the_content(), you need to add the following code:

function example_all_links_nofollow( $content ){
        $content = str_replace( '<a href="', '<a rel="nofollow" href="', $content );
	return $content;
}
add_filter('the_content','example_all_links_nofollow');
