+Gitea doesn't include the canonical tag in their pages, leading to a lot of duplicate pages being indexed by Google. Each page being indexed has a different sorting option, or other superflous parameter.

+
+To fix this,
+
+1. Create a `custom/templates/base/` directory under your Gitea installation. In my case it is in `/var/lib/gitea/custom/templates/base/`.
+2. CD to the base directory and run `wget https://raw.githubusercontent.com/go-gitea/gitea/main/templates/base/head.tmpl`. Make sure your Gitea is updated to the latest version, or choose the right version instead of the `main` branch.
+3. Modify `head.tmpl`: Add this line somewhere in the `<head>` section:
+
+```html
+<link rel="canonical" href="{{AppUrl}}{{if $.Link}}{{slice $.Link 1}}{{end}}" />
+```
+
+4. Restart the gitea service
