We have many partner links leading to unique form pages (for example, site.com/partner1) that are closed from indexing. We plan to change this strategy so that all partner links lead to our main page, using UTM tags for tracking (for example, site.com/?utm_source=partner1), and at the same time, show users a pop-up window with a unique offer from the partner. Are there any risks or recommendations we should consider to maximize the positive effect and minimize potential negative consequences?
