There are many different kinds of trust signals you can use. One of the most common is a money-back guarantee. This assures customers that their purchase is secure if they’re unhappy with the product or service. Another option is social proof. This usually means displaying previous customer testimonials and positive feedback. Lastly, there is “trust by association.” If your company is affiliated with or has done business with another reputable company, display their logo on your site for your visitors.
