In the Google Webmaster Guidelines (http://support.google.com/webmasters/bin/answer.py?hl=en&answer=66356) is recommended that advertising links shouldn't pass PageRank.
You can achieve this by setting the link to 'nofollow'.
If you enter
$link_attributes['attributes']['rel'] = 'nofollow';
in functions simpleads_preprocess_simpleads_img_element and simpleads_preprocess_simpleads_text_element the job is done.
