Can I advertise a hospital and laser clinic website on Google? Do i have to show any certificate to googel or it is same as other websites. Would you please help me?
That largely depends on where you are in the world, see Google's help page on this: http://support.google.com/adwordspolicy/answer/176031?hl=en&ref_topic=1310883 There you can find links to certification forms too, if required.
