Hi, I am creating a PHP login page that will allows specified users to login to view MySQL data stored in a table. I am concerned that the pages the user uses to view sensitive (sales) information might somehow become available to people whom have found the page using a search engine?! I am aware of 'no follow' coding which stops search engines ranking the page but Google does not like sites that use the no-follow rule. Given that the pages are only accessible if you enter a correct username and password, am I worrying about something that is not actually a problem? Or could pages indeed become viewable via search engines even though the user has not entered a username and password?!? Matt.
You can declare "noindex, nofollow" meta too on the page's header. The same on declaring the exempted file to be indexed on robots.txt
