What an SSL Certificate Does
SSL (Secure Sockets Layer) encrypts the data transmitted between your website and visitors browsers. Without SSL, data travels in plain text, making it vulnerable to interception. With SSL, data is encrypted and unreadable to anyone except the intended recipient.
You can identify SSL by the padlock icon in the browser address bar and the https:// prefix instead of http://.
Why SSL Matters
Security: Protects login credentials, form submissions, payment information, and personal data from interception.
Trust: 85% of online shoppers will not enter payment information on a site without SSL. The padlock icon signals legitimacy.
SEO: Google confirmed SSL is a ranking signal. HTTPS sites rank higher than HTTP sites.
Browser Warnings: Chrome, Firefox, and Edge display "Not Secure" warnings for HTTP sites, scaring away visitors.
Types of SSL Certificates
Domain Validation (DV): Validates domain ownership only. Free through Let's Encrypt. Suitable for most websites.
Organization Validation (OV): Validates business identity. Costs ₹2,000-₹5,000/year. Shows business name in certificate details.
Extended Validation (EV): Rigorous validation process. Costs ₹10,000-₹50,000/year. Shows business name prominently in browser.
