How to add nofollow to your wordpress posts

Posted in WordPress · September 20th, 2011 by Kazim · Comments (5)

I was searching around internet all over for adding rel=”nofollow” to external link in my posts. Suddenly, I came over a guy he has a blog that has many external links in its post but they weren’t at nofollow attribute, that blog has PR 0 and was there for more than 2 years. He randomly added no follow to his external links of WordPress posts. He raised up with PageRank 3 within very little time. Google actually links that how much you’ve been linking externally and what sites are they, So my suggestion to you is add no follow to your blog posts. Here is how.

How to add rel no follow to your WordPress posts?

  • Go to Your site > WordPress Admin Panel > Appearance > Editor (Theme editor)
  • Go to functions.php (Theme’s Function)
  • Copy the below code to the new line
function add_link_attr($func='', $args='', $attr='', $imgtag=false) {
 
    $tag = ($imgtag) ?  "<img " : "<a ";
    $tag_attr = $tag . $attr . ' ';
 
    $func_args = array();
    if(!is_array($args)) {
        $args_array = preg_split('/[\,]+/',$args);
        foreach ($args_array as $arg_array) {    
            array_push($func_args, $arg_array);
        }
    } else {
        $func_args = $args;
    }        
 
    if($func) {
        $func_args = array_map('trim', $func_args);
 
        ob_start();
        call_user_func_array($func, $func_args);
        $input = array(ob_get_contents());
        ob_end_clean();
 
        foreach($input as $line) {
            $output .= preg_replace("/$tag/", $tag_attr, $line);
        }
        echo $output;
    }
}
  • Save Changes!
  • Navigate through the page you want to enter the attribute rel nofollow. Mostly i recommend it to add it on single post page if you have summary on the home page
  • Go to single.php (for the single post view)
  • Replace the following:
    • <?php the_content(); ?>

    with

    <?php add_link_attr('the_content', 'Read more', 'rel="nofollow"'); ?>
    • Save changes

    Finally you’re done! You can now check the source of any post page that has external links.

      Dear Done,

      You want to place no follow on non external links, does this mean that you want to leave with follow to external links? Which WordPress version are you using currently?

      Thanks

      I’m afraid I don’t quite follow. What does “Copy the below code to the new line” mean?

      I can’t see where I put that line of code.

      Thanks
      Peter
