What is an SSL certificate?
SSLs are data files that ensure the link between a web server and browser is encrypted and keeps all the data of your users private.
Why buy an SSL certificate?
SSLs add credibility to your brand. A website equipped with an SSL certificate looks more trustworthy, which appeals to customers.
How do SSLs work?
When users access a website, both the browser and the web server have to agree the connection is secure before they exchange data. SSLs provide that secure layer.
And if there is no SSL...
It will cause a chain reaction - the server alerts the browser, that alerts the user to stay away from you site, which will impact your traffic.
How SSLs influence SEO?
SSLs are one of the mandatory requirements Google implemented in website ranking - the SEO ranking algorithm favors websites with an SSL certificate.
SSLs are divided by level of encryption or by the number of domains they cover..
SSLs by level of encryption
• Domain Validation SSLs • Extended Validation SSLs • Organization Validation SSLs
