If a business, organization, or individual has gained a certification, it should prominently publish this fact, since this increases trust in the site. Example certifications include professional and academic qualifications, trade, software, ISO, and safety certifications, to name but a few.

Especially for brands that do not already have a strong association with trust certifications can help lend credibility – usually via the extension of the credibility of the endorsing brand (see Imagery – ‘Famous People & Authority Figures’ & ‘Credible Brands’).
