This is all controlled and done automatically through Javascript which picks up the class placed on the link – so add the class=”authenticatelink” to a link in a widget, post, page, excerpt or even in your site comments and the link will dynamically control its target URL address based on your Web Site users login state.

This is highly beneficial for SEO purposes as you do not need to block entire site pages from unregistered users, just the link is altered – which allows search engines to still index your pages and content. You can grab the plugin from the Dynamic Registration Links page directly.
