Presumed credibility- http://www.greenpeace.org
As the .org web domain suffix was only initially only allowed for established non-profit organisations, the use of such a domain name carries a high degree of presumed credibility (Fogg, Marshall et al. 2001). Moreover, as this is one of the web addresses that would have been available at the very start of the internet, the fact that the webpage still exists does also contribute to the site’s credibility.
The possibility for a website to have reputed credibility (Fogg, Marshall et al. 2001) stems from the fact that they have received some type of award or recognition from an independent third. In this example the site received an Australian Web Award in 2016, making it a reputedly credible site.
Surface credibility- http://www.butterfly.com.au
As surface credibility (Fogg, Marshall et al. 2001) has more to do with first impressions than reputations, http://www.butterfly.com.au does offer a good first impression for people who do not know anything about what the company or website is about.
Earned credibility- http://www.Dictionary.com
The Dictionary.com website does have a high level of earned credibility(Fogg, Marshall et al. 2001) as it has been around for quite some time and has been consistently providing quick and reliable definitions.
