A partner link should never be presented as if it were a neutral citation.
Disclosure
How partner links are handled
Some pages may include partner links in the future. When that happens, the relationship should be clear and the pricing comparison should stay readable either way.
Principles
What disclosure means on this site
If no partner relationship is active, the page should send users to the official pricing page instead of a placeholder destination.
A provider should not win the main spot purely because it pays more if the price gap stops being reasonable.
