Hi Diawn,
Allow me to interject some information. When the link in Pages isn't active it won't be active when created to a PDF. Yes Adobe Reader will see it as active, Preview won't. Typing a web address doesn't make it a active link.
To activate a hyperlink in Pages:
1. Highlight the entire link in pages
2. Open the inspector, click the second to last icon, Link Inspector.
3. Click Enable as a Hyperlink.
4. Chose Link to: Webpage
5. Fill in the URL line as needed.
You're active hyperlink is now created. Both Preview and Adobe Reader will see it as active.
Do let us know if this helps you.
Sincerely,
RicD
