SSL certificates: what they are and why they matter for your site
If you've ever noticed the green padlock symbol in the browser's address bar, that's the work of an SSL certificate. Here's what actually happens behind it and why it matters for your site.
What is SSL?
SSL (Secure Sockets Layer) and its modern form TLS (Transport Layer Security) encrypt the data exchanged between a visitor's browser and your website's server. Without SSL:
- Passwords typed by users can be stolen by ISPs
- Payment card details can be intercepted by anyone on the same Wi-Fi
- Page content can be altered in transit (for example to inject ads)
Why SSL matters
1. SEO advantage
Google has counted HTTPS as a ranking signal since 2014. HTTPS sites rank higher in search results.
2. User trust
Chrome, Firefox, and Safari display a "Not Secure" badge next to HTTP sites. More than 80% of visitors will leave when they see such a warning.
3. Payment processing
All payment gateways (Evoca, Idram, Telcell) require calls from HTTPS sites. Without SSL you simply can't accept online payments.
4. Personal data protection
GDPR and Armenia's law on personal data protection both require secure transmission of personal data. SSL is the foundational layer for that.
How much does SSL cost?
Good news: nothing. Since 2015 Let's Encrypt has issued free, auto-renewing SSL certificates. Quality hosts (MyWeb.am among them) integrate with Let's Encrypt directly - the certificate activates in one click.
