We run a SAAS subscription business. It's a church management software. Churches use our software to manage their people, groups, online giving, etc. Within their church account, they can get a unique link to embed on their church website where people can give a financial contribution. That link is a "sub-domain" link. For example: app.website.com/yourchurchname I am trying to determine if we are getting SEO help to our main website when somebody embeds that subdomain link on their church website or if we need to be doing this differently to capture all these free backlinks. Thanks for your help!
