Here are examples of trustworthy websites.
This is the website of Médecins du Monde, international NPO for medical issues, and an example of presumed credibility. The ‘org’ sign shows that this organization is fair, right. Thus, this website is credible.
Final example slide is for earned credibility. I have used the website ‘Amazon’ before, and there was no trouble such as delivery or money transferring. This is why I keep purchase goods on this website. Moreover, even though those who have not used this website, they can rely on other’s experiences. This shows the earned credibility of the website.
