May i know how Secure Socket Layers (SSL) differs from Transport Layer Security (TLS)? And what is the most preferred choice when it comes to SEO?

Brief answer for : use TLS (modern versions) — not the old SSL protocol family — and serve your site sitewide over HTTPS. Today the practical distinction is this: TLS 1.2 and 1.3 are the secure defaults; SSLv2/SSLv3 and the older TLS 1.0/1.1 are considered insecure and should be disabled. (rfc-editor.org)

For SEO the important part is a correctly configured HTTPS site, not the name you use. Google treats HTTPS as a (lightweight) ranking signal and published migration guidance: use strong keys/certs, redirect HTTP -> HTTPS, avoid blocking the HTTPS site from crawling, update canonicals and sitemaps, and submit the HTTPS property to Search Console. Follow those steps to avoid indexation or ranking problems during a migration. (webmasters.googleblog.com)

Quick, practical checklist:

  • Enable TLS 1.3 (and TLS 1.2 for compatibility); disable SSLv2/3 and TLS 1.0/1.1.
  • Use up-to-date cipher suites per Mozilla/industry guidance and test configuration.
  • Serve everything via HTTPS (no mixed content).
  • Add HSTS (with careful staging and preload only after testing).
  • Test with an analyzer like Qualys SSL Labs and follow OWASP hardening recommendations. (ssl-config.mozilla.org)

HSTS example header to add once you are confident the site is fully HTTPS:

Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

Notes and common pitfalls: mixed-content resources and unchanged canonical tags are the usual causes of post-migration errors; short, temporary traffic fluctuations are normal if redirects or Search Console settings are missed. ’s naming point is useful background, and ’s TLS/SSL comparison reflects an earlier-era view — current guidance is to prefer TLS 1.2+ and follow the links above for implementation details.

"SSL" means "Secure Sockets Layer". This was coined by the inventors of the first versions of the protocol, Netscape (the company was later bought by AOL).
"TLS" means "Transport Layer Security". The name was changed to avoid any legal issues with Netscape so that the protocol could be "open and free" (and published as a RFC). It also hints at the idea that the protocol works over any bidirectional stream of bytes, not just Internet-based sockets.(null)

TLS V1.0 is marginally more secure than SSL V3.0
