Is there any ways to put advertisement on .github.io domain, many ads needs a sever to type command to it, and I can’t type command to github sever, so is the any way to put ads ?
I don’t think you’re supposed to even try, as I understand the Pages terms:
GitHub Pages is not intended for or allowed to be used as a free web hosting service to run your online business, e-commerce site, or any other website that is primarily directed at either facilitating commercial transactions or providing commercial software as a service (SaaS). Some monetization efforts are permitted on Pages, such as donation buttons and crowdfunding links.
Yup, so monetization just like donation buttons are allowed. What is not allowed is to use GitHub Pages as a full hosting platform for an e-commerce or anything similar to that.
