Can I link to my institution's site from Reddit & Quora ads?

No, that will cause your ad to be flagged as spam

Reddit and Quora do not support one account (like Keystone's) running ads that link to multiple websites. They do not yet offer partnership ads like Meta do to help facilitate this.

Your ad will instead be linked to your profile on Educations.com and you will receive a report on all impressions of your Reddit & Quora ads as well as clicks through to your Educations.com profile.
