Welcome to the Q&A Forum

Thank you. Can you also not only check if the visitor is coming via search BUT also keyword used so I can make my notices more specific?

Thanks for you reply Alan.

it could be any one out of the following 3 scenarios. 1: The page in question was moved at some point and since the CMS still accepts the old URL, when google re-visits the old URL it still finds it. So in this scenario it will find both the old URL and the new URL and index both. 2: google hasn't revisited the page for a long while but it is still in it's index, even though it would get a 301 by the CMS when it visits the page. Can be easily fixed by going to webmaster tools and ask it to remove it from the index. 3: there are still links to the old URL either on site or off site and since the CMS doesn't 301 the oid page it will index it again with a new URL. 4:the page still exists in the CMS because of some strange setting or equivalent in the CMS. as mentioned before the easy fix is to use a robots.txt and deny access to the page and ask google to remove it from it's index. the better fix is to find the problem in the CMS and solve it. a midway fix could be to 301 it in the .htaccess or equvilent on an ISS server. hope it helped
