Yes, having an SSL certificate can improve your website's search engine rankings. Google has stated that HTTPS is a "lightweight" ranking signal, which means that it's not the most important factor in search rankings, but it can give your website a small boost. In addition, Google Chrome and other web browsers display a "Not Secure" warning for websites that don't have SSL certificates installed, which can discourage visitors from staying on your site. By having an SSL certificate installed, your website will display as secure, and visitors are more likely to trust your site and stay longer. Ultimately, having an SSL certificate can improve your website's user experience and increase its search engine visibility.
