Add visual signs of security

Although most users form an opinion about a site's security based on their gut feeling, designers can reinforce this feeling of trust by ensuring the website has the following:

• Security badges or trust seals: "SSL seals" issued by SSL certificate vendors like Norton, Thawte, Trustwave, Geotrust, or Comodo denote secure communication between a browser and a site. Furthermore, trust seals like Google Trusted Store, BBB Accredited, and TRUSTe indicate to users the business is legit and that they can trust it.
• A padlock icon and HTTPS protocol: The HTTPS protocol provides a layer of encryption that can help ensure the confidentiality and integrity of data exchanged between a web browser of users and a website. A tiny detail such as a padlock icon can also provide enough visual security cues to increase users' perception of security.
