A simple way to increase a site’s credibility is to clearly display your contact information: phone, physical address and email address.
Choose a design that offers a professional look or is appropriate to the site’s objectives
People quickly rate a site by its graphic design only. When designing your site, pay attention to layout, typography, images, consistency issues, etc. Of course, not all sites gain credibility by adopting a look similar to that of IBM.com. The graphic design must be consistent with the objectives of the site.
Make your site easy to use — and useful such as white label marketing dashboard.
Here, two rules are grouped together. Research shows that sites gain credibility by being both easy to use and useful. Some site operators forget about users when they serve their own corporate ego or try to show what they can do with web technologies.
Regularly update your site or at least show that it has been revised recently
People give more credibility to sites whose content has recently been revised or updated.
Make limited use of any promotional content
If possible, avoid ads on your site. If you need to integrate ads, clearly distinguish the advertising content from the site’s content. Avoid pop-up ads unless you’re indifferent to annoying users and losing credibility. Adopt a clear, direct and sincere writing style.
