I run a wordpress blog and it has a voting plugin installed, the problem is that the voting button using Ajax technology and when Google crawl my site it looks for the "voting" URL too which doesn't exist, therefore Google showing error message in Google Webmaster Tools that the no. of Not followed pages have increased. The links are like - wp-admin/admin-ajax.php?action=wti_like_post_process_vote&task=like&post_id=6571&nonce=9e0ce65073 I want to ask that is it possible to "block" wp-admin/admin-ajax.php and all links after that so that Google should not go after them? Or may be some other option you suggest?
You can use <meta name="googlebot" content="noindex"> Since you are using Wordpress, create another header php for to include for no-index pages.
