Why you should put Privacy Policy on your websites
There are certain parts of a typical website such as contact forms, and some that collect visitor information for tracking statistics such as Google Analytics. With this, every website should have a page stating its privacy policy so that the user is aware what kind of data you collect each time they visit and each time they submit something in a form.
Including a privacy policy would protect both the publisher and the user. It would protect the publisher if he/she abides by the privacy policy stated. And oh, if you use Google Adsense in your websites, forums, or blogs, remember to include a Privacy Policy. It is recommended to use a nofollow link for your Privacy Policy page.
