An e-commerce trustmark is a badge, image or logo found on an electronic commerce website that indicates the site is a member of a professional organization or has passed security tests.
The trustmark is used to shows approval branding of a well-known third company. Displaying an e-commerce trustmark helps online businesses show customers they are a member of a professional accreditation organization, or show they have passed security and privacy tests. When you display a trustmark that reflects a well-known company or industry organization, it can give customers confidence and can encourage them to do business with you.
Some common e-commerce trustmarks include those for SSL security, Better Business Bureau, Chamber of Commerce, hacker-free, and others. May also be written as trust mark.
