Welcome to the Q&A Forum

Hi William, Moz would be picking up these URLs because they are linked internally, and they are being reported as duplicates because these pages are identical and there are no canonical tags in place. https://im.tapclicks.com/signup.php should have a self referring canonical tag so that any query strings added to the end of the URL are canonicalized back to https://im.tapclicks.com/signup.php Adding this canonical tag will resolve these 'High Priority' issues Cheers, David
