Companies gain credibility through their websites in four different key ways.
When a companies website ends in .org there is a reputation of a credible organization. There is a similar credibility with custom email addresses. Having this first step of imaging goes a long way to improving your first impression.
Being considered a leading authority in a field or profession also gives you credibility. When you have a blog or white papers on your site that are informational and useful you build a sense of authority with your audience.
Your site looks professional, therefore you are professional. As much as this can be an oversight, it is also how a large portion of people judge companies and organizations.
Think of your website as your online headquarters. Just because you have a nice building doesn’t necessarily mean that you are a good business. However, having a broken down or unsightly building can turn people away. Same goes for websites. Looking professional is part of being professional.
If you have a website with broken links and missing content, there is a good chance you are leaving an impression of bad service and cheap work. You can earn credibility through consistent past experience. If your site, company, and team all work well. the perception of your business will grow.
