- Accessibility is a federal matter: the Justice Department’s ADA guidance covers the websites of businesses open to the public. ADA.gov guidance
- A federal rule (16 CFR Part 465) makes it unlawful to write, buy or sell fake reviews and testimonials, so the reviews on a business website have to be real. 16 CFR Part 465
- Newsletters and promotions sent from your business email must include a working way to unsubscribe (16 CFR Part 316). 16 CFR Part 316
