I have added the following code for NoFollow for SEO purposes -
Social Widget
echo '<a target="_blank" rel="nofollow" href="'.$ref_url.'" class="preloading_background avia_partner1 link_list_item'.$kriesiaddwidget.' '.$firsttitle.'" >'.$image_url.'</a>';
if($this->add_cont == 2) echo '<a target="_blank" rel="nofollow" href="'.$ref_url2.'" class="preloading_background avia_partner2 link_list_item'.$kriesiaddwidget.' '.$firsttitle.'" >'.$image_url2.'</a>';
Footer
$kriesi_at_backlink = apply_filters("kriesi_backlink", " - <a href='http://kriesi.at' rel='nofollow'>Enfold Theme by Kriesi</a>");
However, when I check on console it doesn't seem to show??
Link to the site is - http://www.haramaintours.com/
It is working.
If you want to check,
open website and press CTRL + U, this will load the source code.
Then CTRL + F, this will open search, then type rel="nofollow" in search
You will get the desired result.
