Improve pages that lead to external ressources

[hirasso]

Describe the problem

If you google for example "swup gtag plugin", the first result will be the (empty!) gtag-plugin page on the docs, that's only there to direct visitors directly to what is set in external_link:

Right now these links are broken due to the new docs structure: https://swup.js.org/docs/third-party-integrations/gtag-plugin.html. But they will appear again. This time at https://swup.js.org/docs/third-party-integrations/gtag-plugin/ (without the .html extension):

An empty page with no information.

Describe the proposed solution

We have a few options to make this experience smoother:

• Completely exclude these pages but still have them in the menu (I'm not sure if this is easily possible)
• Keep the pages around for search engines but improve their layout, for example (my favorite solution):

• We could even improve the pages but also introduce a <meta name="robots" content="noindex, follow"> tag

What's your opinion on this?

Another solution could be a html redirect on these pages:

<meta http-equiv="refresh" content="0; URL='https://github.com/joshuaHallee/swup-gtag-plugin'">
