This plugin allows you to make a WordPress page (or post or custom post type) link to a URL of your choosing, instead of its WordPress URL. It also will redirect people who go to the old (or “normal”) URL to the new one you’ve chosen.
Common uses:
Set up navigational links to non-WordPress sections of your site or to off-site resources.
Publish content on other blogs (or other services, like Medium) but have them show up in your WordPress posts stream. All you have to supply is a title and a URL. The post title will link to the content on the other site.
For store operators, you can link to products on other retailer’s sites (maybe with an affiliate code) but have them show up like they’re products in your store.
Create a “pretty URL” for something complicated. Say you have https://example.com/crazy-store-url.cgi?search=productId&sourceJunk=cruft … just create a WordPress page called “My Store” and use Page Links To to point it to the ugly URL. Give people the new URL: https://example.com/my-store/ and it will redirect them!
