Third-party endorsements policy
eBay doesn't allow third parties to provide logos or statements that claim to vouch for a member's trustworthiness. You can include information in your listing about your eBay reputation, such as your Feedback ratings.
However, you can't make statements about your reputation as a seller in a way that buyers can't verify. You also can't include endorsements from other people or companies that talk about your trustworthiness as a seller, because buyers can't verify those types of claims.
Make sure your listing follows these guidelines. If it doesn't, it may be removed, and you may be subject to a range of other actions, including limits of your buying and selling privileges and suspension of your account.
What are the guidelines?
Statements that guarantee the transaction or item, but don't guarantee the seller. Examples include;
"Satisfaction guaranteed or your money back."
"Protected transaction guaranteed for up to $25,000."
Statements about seller confidence because a buyer can easily verify this claim. Examples include;
"Buy with confidence! I have over 1,000 positive Feedback ratings."
Third-party statements, seals, or logos that vouch for the trustworthiness of a seller, such as:
"This eBay seller is extremely reliable and reputable."
"Buy with confidence from a trusted seller."
Statements, seals, or logos that manipulate eBay's Feedback system because buyers can't verify these claims. For example, "100% positive Feedback in authentic watches."
Why does eBay have this policy?
Since we can't verify the trustworthiness claims made by third parties, we don't allow these claims in listings. Manipulating any eBay reputation system, such as Feedback ratings, could confuse or mislead buyers.
