I have a shopping cart which uses AJAX to add/remove items to the cart from an
<a> styled as a button which links to an action like
These links keep getting crawled by search engines - however, since the nonce is different each time, the list of crawl errors keeps growing.
What's the most effective method to prevent search engines from trying to follow the link? I understand that a simple
nofollow may not be appropriate for internal links. Alternatively, I am misusing the
<a> tag and would another element and a bit of jQuery to follow the
admin-ajax.php link be better?
