Hello,
I must sign up for this topic, too.
I have noticed the following errors in mass amounts on my store:
403 and 404s with the following stucture (these are considered real urls by the googlebots!) and unfortunately,even though I have specified the url parametre to be non-crawable, it’s still showing them to me as errors:
– /some-category/?add_to_wishlist=..
-/some-product/?add_to_wishlist=..
– even the following, which is disallowed now by my robot.txt file already, but just for the record:
/wp-content/plugins/yith-woocommerce-wishlist/yith-wcwl-ajax.php?action=add_to_wishlist&add_to_wishlist=..
I guess it’s also my mistake I didn’t disallow the plugins folder earlier, but this mistakes of indexed plugins from the plugin folder are ONLY for the yith plugin and they are hundreds for me.
I have noticed the problem quite late, I must admit. It’s not unsolvable but if you leave it it may cause huge pagerank losses in time. So if this is caused by the plugin it should be at least documented I think so that measure are taken with these parametres in advance and not after seeing the 1k errors in GWT.
