Another signal of trust is when an agency has a strong social media presence, and that they work to post and interact with their clients. It takes time and effort to be present online, so when an agency updates and responds to questions, it shows they are legitimate and care about their customers.
If you can't get in touch with an agency when you need help, they aren't much of a benefit. You need to work with an agency that allows you to contact them easily - whether by phone, text, email, or through their website. Allowing you to contact them with any questions is important and illustrates their legitimacy.
It’s important that you choose an agency that is focused on being transparent online, as this builds trust. Signals of trust include providing agent and owner information on the website and responding to customer reviews in a timely manner. This illustrates that the agency is legitimate.
