Yes, links can be included in questions, but the format for including them may depend on the platform you are using. For example, in markdown format, you can create a clickable link like this:
[Link Text](http://example.com)
In plain text, you can simply paste the URL, and many platforms will automatically convert it into a clickable link. However, if you're using a specific application or website, please check their guidelines regarding the inclusion of links in questions.
