Trust. Search engines like Google, Bing, etc., are looking for signals that signify trust. Search engines want to give searchers the best possible result. That’s why you need to work on your trustworthiness on all levels, both technical as well as in content.
Use up-to-date software, have your SSL in order, make strong passwords, use tools such as Cloudflare to protect your site from DDoS attacks. An SSL Certificate (Secure Sockets Layer) is a set of data files that you can add to your server to achieve this encrypted connection between a browser and your server. Besides securing your website by way of encryption, it also helps with SEO (Google Rankings). Google has confirmed that HTTPS is a ranking signal. An unsecured website risks users’ online safety and could be hurting your SEO efforts. Google confirmed way back in 2014 that HTTPS is now a ranking signal. So, if your site doesn’t have SSL certificates and is on HTTPS, then now would a good time to update.
A SSL certificate increases customers trust and confidence in your website. Customer confidence is essential to increasing conversion rates.
