CDN & Delivery

Action

No CDN detected

FIX

No CDN detected

A CDN can significantly improve load times for users around the world by caching content at edge nodes closer to them.

No CDN detected

Consider using a CDN to improve global delivery speed and reduce origin load.

IPv6 Readiness

Action

No IPv6 support

REVIEW

No IPv6 support

No IPv6 (AAAA) records found

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

No IPv6 Support

About 40% of internet users have IPv6. Consider adding AAAA records.

IPv6 support is increasingly important for global accessibility. About 40% of internet users have IPv6 connectivity.

Why this matters

No AAAA records — same impact as 'no IPv6 (AAAA) records'; IPv6-preferring clients pay extra latency falling back to IPv4.

URL Variants

www/non-www, trailing slash, HTTP→HTTPS

REVIEW

www/non-www, trailing slash, HTTP→HTTPS

Both www and non-www versions serve content

Got: Both variants return 200 Expected: One variant 301-redirects to the other

HTTP correctly 301-redirects to HTTPS

www / non-www

200https://www.eluniversal.com.mx/

200https://eluniversal.com.mx/

Inconsistent — duplicate content risk

HTTP → HTTPS

Recommended actions

Prefer TLS 1.3 — TLS 1.2 is acceptable but TLS 1.3 removes RSA key exchange and improves latency
Enable HSTS: Strict-Transport-Security: max-age=31536000; includeSubDomains
Enable DNSSEC on your domain for DNS spoofing protection
Enable OCSP stapling on your TLS server to remove a CA roundtrip and protect user privacy

Crawlability

robots.txt present, sitemap with 0 URLs

PASS

robots.txt present, sitemap with 0 URLs

robots.txt is present

Got: 3722 bytes

sitemap.xml is present

sitemap.xml is valid XML

sitemap.xml is empty — no URLs found

An empty sitemap provides no value. Add <url> entries for your pages.

robots.txt references sitemap

An empty sitemap provides no value. Add <url> entries for your pages.

Why this matters

An empty sitemap signals 'no content to index' to Google — actively harmful versus having no sitemap at all.

Learn more ▾

Google compares URLs in the sitemap against URLs it has crawled. An empty sitemap on a site with thousands of pages signals abandonment. Either populate it correctly (most CMSes auto-generate) or delete the file and let Google crawl normally.

Data source: whois (0.4s)

The domain can be transferred without an unlock step. Enable registrar lock (clientTransferProhibited) in your registrar's control panel to protect against unauthorized or accidental transfers.

Why this matters

Without registrar lock, an attacker who phishes your registrar credentials can transfer the domain in minutes — total brand hijack.

Learn more ▾

Registrar lock (clientTransferProhibited, clientUpdateProhibited, clientDeleteProhibited) requires extra verification before any transfer/update/delete. Every major registrar offers it free. Combined with 2FA on your registrar account, it's the strongest defense against domain hijacking.
