The point of a disclosure page is to disclose and make certain interests obvious that otherwise might not be.
While not required, it’s a good idea to create such a page that you can link to from any content where you’re engaging in affiliate marketing.
- Disclose how your website makes money.
- Disclose any conflicts of interest.
- Disclose any form of compensation you receive. An example would be if you run a travel site and companies occasionally pay you to visit their hotel and accommodation for a review. That needs to be disclosed. If you receive payment for any products or services you recommend. That needs to be disclosed.
The point is to be transparent to your end visitor and make clear any compensation and/or conflicts of interest that might not otherwise be obvious. That’s what needs to be disclosed.
