An SSL certificate ensures that personal data such as names, addresses or credit card numbers cannot be read or changed by unauthorised third parties during transfer. SSL encryption is used, for example, in web shops and bank sites. Here it is indispensable, even mandatory when transmitting personal data.
In addition, the use of an SSL certificate has an impact on a website‘s ranking in search engines. Websites with their own SSL certificate are ranked higher and are therefore displayed higher up in the search results.
