Web Links Component
The WEB LINKS component enables you organise your website's links to external websites.
You may also create links to content within your own website - providing you use the URL of the destination.

The WEB LINKS Component is decoupled
Decoupled means the core component is no longer shipped with the Joomla! CMS.
Decoupled core components will in future be made available by the Joomla! Project for separate download and installation.
Once installed they can be updated like any other extension.
If your Joomla! CMS does not include this component then you may download it from the Joomla! Extensions Directory - see link below.
Other ways of adding Web Links to your website
You could if you wish simply add an External URL Menu Link to a Menu.
And you can create a link in any Article when you use the Content Editor.
