When promoting VPN services, it's crucial to comply with advertising and disclosure regulations in your jurisdiction. In the United States, the Federal Trade Commission (FTC) requires affiliates to disclose their relationships with the brands they promote, ensuring transparency for consumers. Include clear and conspicuous disclosure statements on your website, social media profiles, and any promotional materials indicating that you may receive commissions for VPN signups. Additionally, avoid making false or misleading claims about the VPN services you promote, as this can damage your credibility and potentially lead to legal consequences.
