Deprecated TLS version detected — the fix
The server supports TLS 1.0 or TLS 1.1, which are deprecated protocols with known security vulnerabilities.
Where this fits: security in SEO
Security issues erode both rankings and trust. HTTPS has been a ranking signal since 2014, and browsers actively warn users away from insecure or mixed-content pages — a warning interstitial is a 100% bounce rate. Missing security headers rarely block indexing, but they widen your attack surface, and a hacked site (injected spam, malicious redirects) can be removed from results entirely. Security is the SEO work you do so you never have to do recovery work.
Why deprecated tls version detected hurts your rankings
TLS 1.0 and 1.1 have known vulnerabilities including BEAST, POODLE, and weak cipher suite support. Major browsers have dropped support for these versions, and PCI DSS compliance requires TLS 1.2 or higher. Using deprecated TLS exposes users to potential data interception.
This is a critical issue: it can remove pages from search results entirely or block them from being crawled at all. Treat it as an outage, not a backlog item — every day it persists is compounding lost visibility.
How to fix it
Disable TLS 1.0 and 1.1 on your server and require TLS 1.2 or 1.3 as the minimum version. Update your server configuration (nginx, Apache, etc.) to only allow modern TLS versions and strong cipher suites.
# nginx

ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256;Security best practices
- Serve everything over HTTPS and redirect HTTP with a single 301.
- Send HSTS, X-Content-Type-Options, and a Content-Security-Policy on every response.
- Eliminate mixed content — one insecure asset breaks the padlock.
- Keep dependencies and CMS plugins patched; most site hacks are known-CVE exploits.
- Monitor Search Console's security section — Google often knows you're hacked before you do.
