If true, external URL links in wiki text will be given the rel="nofollow" attribute as a hint to search engines that they should not be followed for ranking purposes as they are user-supplied and thus subject to spamming. Defaults to true.

Setting nofollow for red links

It may be desirable to configure MW to append rel="nofollow" to internal links that point to pages that haven't yet been written (so-called "red links") for various reasons that include avoiding unnecessary crawler traffic to non-extant pages or for the possibility of improved SEO by avoiding punitive action against a site's ranking due to the presence of "broken links" that aren't broken, just not yet authored.

This may be accomplished by using the HtmlPageLinkRendererEnd hook as follows:

// Add rel="nofollow" to links to pages that don't exist (redlinks)
$wgHooks['HtmlPageLinkRendererEnd'][] = 'noFollowRedLinks';
function noFollowRedLinks(
    $linkRenderer, $target, $isKnown, &$text, &$attribs, &$ret)
    if (!$isKnown && preg_match('/\bnew\b/S', $attribs['class'] ?? "")) {
        $attribs['rel'] = 'nofollow';
    return true;
