Why we need Affiliate disclaimer?
An affiliate disclaimer is important for both legal compliance and maintaining trust with your audience.
In countries like the United States, the Federal Trade Commission (FTC) requires bloggers and content creators to disclose affiliate relationships clearly. 1
- You must tell your readers you earn a commission if they buy through your affiliate links.
- Non-compliance can result in fines, account bans, or loss of affiliate programs like Amazon Associates.
People value honesty. When you openly share that you’re using affiliate links:
- Readers appreciate your transparency.
- They’re more likely to support you by clicking/purchasing through your links.
- It prevents them from feeling tricked or misled.
Many affiliate programs like Amazon Associates, ShareASale, Commission Junction, Impact explicitly require you to add a clear and visible disclaimer on your blog or post.
Google values authenticity and transparency. Having a disclaimer Aligns with Googleโs E-E-A-T principles (Experience, Expertise, Authoritativeness, Trust).
Final Thoughts
By automatically inserting an affiliate disclaimer into every blog post, you save time, stay compliant, and build reader trust. Whether you’re using Amazon, ShareASale, or any affiliate platform, this small step goes a long way.
