Why does my organization's website need an SSL certificate?
Secure Your Website and Build Trust
Seeing “http://” in the web browser's address bar means “this is a website” to the user, but seeing “https://” means “this is a website, and it’s using SSL to encrypt data and authenticate the website.” In general https-enabled websites are regarded as more trustworthy for visitors.
Search Engine Optimization
Various search engines, including Google, are favoring https-enabled websites when displaying web search results.
