To be honest, an SSL certificate is far more relevant for another essential factor: it helps improving the conversion rate. There is no doubt that this certificate positively influence the overall user experience as well. If a person opens an unsafe website, he would notice a message showing that the site is not secure. By explicitly pointing out unencrypted websites, web browsers are strengthening the awareness about internet security.

The more trust your customers have in your website, the more likely the website will increase its conversion rate. Trust is one of the main factors when users decide where and whether to shop. A website well defended from cyber risks, especially when personal or payment information is needed, can make a great difference in a customer’s purchasing decisions.

To the average user, the difference between the levels of verification is unnoticeable. Additionally, very few visitors actually click on the locker to see the details of the certificate.
