WordPress users, if they want their private and very personal information, such as account information or login information, especially security for the transmission of their data. And they also have data that should remain secret, such as payment information of their online shop, etc. In times of hacker attacks on private PCs (and even more so by companies), it should be their concern that users who overlook their website , are interested in the products offered there and order something can also assume that their data safely arrive at them. You can take care of this by encrypting your data transmitted between the users and the website, using SSL or TLS. You do not even have to use an expensive service. It's also free, with Let's Encrypt. This free service is offered by the webhoster.de AG, This tutorial will show you how to install and activate a free SSL certificate from Let's Encrypt so you can use it with WordPress. But not only from a security point of view should you use Let's Encrypt to encrypt the personal data of your customers and their data. Rumor has it that the algorithms also rank websites with SSL encryption better. They can, if you integrate Let's Encrypt into WordPress, also do something for the ranking of their website.

SSL encryption generally has the advantage that the users who visit their website trust this setting. Because secure encryption is also a great success for your online shop. If you can not provide encryption for your online shop, usually no user trusts them either. A disadvantage in particular with the free SSL coding of Let's Encrypt is that the certificate has only a validity of 90 days. This means SSL encryption is only valid for this limited period of time. 30 days before expiration, however, they will receive a message that will offer them an automatic renewal.
