Redirect Chain

Action

2 redirect(s), 1361 ms total

FIX

2 redirect(s), 1361 ms total

2 redirects before reaching final URL

Each redirect adds latency. Try to minimize the chain to 1 hop.

HTTP to HTTPS redirect present

WWW normalization redirect

2-hop chain could be reduced to 1 hop

Redirect directly from https://emory.edu to https://www.emory.edu/home/index.html

Redirect overhead: 1361 ms total

Got: 1361 ms

Each redirect adds latency. Try to minimize the chain to 1 hop.

Why this matters

Redirect chain — each hop adds latency; combine into one redirect where possible.

Redirect directly from https://emory.edu to https://www.emory.edu/home/index.html

Why this matters

Redirect chain could be flattened to one hop — server config tweak removes intermediate latency.

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.

Crawlability

robots.txt present, no sitemap

REVIEW

robots.txt present, no sitemap

robots.txt is present

Got: 3162 bytes

No sitemap.xml found

A sitemap helps search engines discover and index your pages more efficiently.

robots.txt does not reference a sitemap

Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

A sitemap helps search engines discover and index your pages more efficiently.

Why this matters

No sitemap.xml — Google relies on crawl-graph discovery alone, slowing indexing of deep or fresh URLs.

Learn more ▾

A sitemap accelerates Google's discovery of new and updated content. Most CMSes auto-generate one; static-site frameworks need a build-step plugin. Reference it from robots.txt and submit in Search Console to confirm Google can fetch it.

Source: sitemaps.org / Google Search Central

Add a 'Sitemap:' directive to robots.txt so search engines can discover your sitemap.

Why this matters

robots.txt omits Sitemap: directive — crawlers must fetch /sitemap.xml by convention; reliable but missing the explicit hint.

TLS Certificate Expiry & Recommendations

REVIEW

Certificate validity

192

days left

0d 30d 60d 90d+

Recommended actions

Prefer TLS 1.3 — TLS 1.2 is acceptable but TLS 1.3 removes RSA key exchange and improves latency
Add includeSubDomains to the HSTS directive
Add the preload directive and submit to hstspreload.org once max-age + includeSubDomains are in place
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

CAA	Lookup not available with standard resolver

Resolved in 629 ms

CAA record lookup requires a specialized DNS resolver. This check will be available in a future update.

Why this matters

Informational: CAA (Certification Authority Authorization) records weren't checked in this scan.

Slow DNS adds latency to every page load. Consider a faster DNS provider.

Why this matters

DNS resolution is slow — anycast DNS providers (Cloudflare, Route 53) typically resolve <50ms globally.
