Should you use
rel=sponsored on internal links? Here is the scenario: a company accepts money from one of their partners to place a prominent link on their home page. That link goes to an internal page on the company's website that contains information about that partner's service.
If this was an external link that the partner was paying for, then you would obviously use
rel="sponsored" but since this is a link that goes from
awebsite.example/some-page/, it seems odd to qualify that link in this way.
Does this change if the link contains a "sponsored" label in the text (not in the rel qualifier)? Does this change if this link looks more like an ad (i.e. a banner image) vs. regular text (i.e. a link in a paragraph)?
