Email health36Needs work
You have DMARC set up, but in monitor-only mode — it's not actually rejecting spoofed mail.
No SPF record is published, so nothing tells mail providers who's allowed to send as you.
Branded domain email address (vs free Gmail/Yahoo)
Your published contact email is on a free service, not your own domain.
Email forwarding service detected (improvmx, forwardemail, etc.)
We didn't detect any mail forwarding — your inbox provider is unclear.
Lead magnet / signup incentive detected (free download, ebook, etc.)
We didn't find a lead magnet on your homepage — no free download, sample, or signup incentive. Visitors who aren't ready to buy have nothing to take with them.
Mailto: direct contact link present
We couldn't find a tap-to-email link anywhere on your site.
Free-email exposure on contact page (gmail/yahoo/outlook visible)
Your published contact address is on your own domain, not a free inbox.

SEO57Solid
Schema.org structured data presence
Your homepage doesn't publish any Schema.org structured data. Search engines and AI tools fall back to guessing what your site is — and they guess wrong more often than not.
Schema.org type validity (parsed JSON-LD)
We didn't find any structured-data tags on your homepage.
No breadcrumb schema is published. Search engines can't show breadcrumb trails under your listings, and visitors lose the trail to important pages.
hreflang for multi-language sites
You serve multiple languages but don't publish hreflang tags. Search engines may show the wrong version to visitors in other countries.
Title, meta description, OG, Twitter cards, canonical
Your homepage has the title, description, OG, Twitter, and canonical tags.
Your homepage has a clear H1 heading — search engines and screen readers know what the page is about.
Internal link depth (clicks from homepage to deepest content)
Important pages are reachable in just a click or two from your homepage.

Performance63Solid
Your server still serves over the older HTTP/2 protocol — not the newer, faster HTTP/3.
Image optimization (WebP/AVIF)
Your images are served as JPEG or PNG when modern formats (WebP, AVIF) would cut their size by 30–60% with no visible loss.
Lazy loading on below-fold images
Images below the fold aren't lazy-loaded — visitors download them up front even if they never scroll that far.
Mobile PageSpeed score + Core Web Vitals (LCP, FCP, CLS)
Your homepage is mid-pack on mobile. Reasonable but Google's ranking signal rewards faster sites.
Your server compresses pages with Brotli or gzip — visitors download a fraction of the raw size.
7 additional standards didn't apply to this category
Privacy63Solid
Terms of service page presence
No terms of service page found. Without one, you have no contractual basis for the relationship with your visitors.
Your homepage loads a moderate number of third-party trackers. Worth auditing what each one is for.

Yelp presence + rating + review count
We couldn't find a Yelp listing for this business. Local-business searches and recommendation engines lean on Yelp as a signal.

Security80Excellent
Your server doesn't staple OCSP. Visitors' browsers may have to contact the CA themselves, slowing first connects.
Neither OCSP stapling nor Must-Staple is in play. A revoked cert wouldn't be caught quickly.
Certificate key strength and signature algorithm
Your certificate uses outdated key strength or a SHA-1 signature. Reissue with a modern ACME-class cert.
Embedded SCT count (Certificate Transparency)
Your certificate carries only one embedded SCT — modern browsers want at least two. Reissue from a CA that includes them.
Certificate validity-period brevity
Your certificate lifetime is on the longer end (> 90 days). ACME-class certs renew every 60-90 days and rotate cleanly.
SSL certificate validity & expiration window
Your SSL certificate is valid and not close to expiring.
WordPress REST API user enumeration exposure
Your WordPress REST API doesn't leak usernames — attackers can't list accounts without already being authenticated.
Sensitive path exposure (.git, .env, /admin, xmlrpc.php, wp-login.php)
None of the common admin or developer paths are publicly reachable.
Only modern TLS (1.2 and above) is offered — TLS 1.0 and 1.1 are turned off.
Certificate chain completeness
Your server sends the full certificate chain — every device builds the path to a trusted root cleanly.
Your certificate is issued by a tier-1 publicly trusted CA (Let's Encrypt, DigiCert, Google Trust, Sectigo, etc.).
Your TLS handshake completes quickly — under 300ms on a cold connection.

Accessibility100Excellent
Every image on your homepage has alt text — screen readers can describe them.
Your heading levels are properly nested — H1, then H2s, then H3s — and screen readers can navigate the outline.
Text on your homepage meets WCAG AA contrast minimums — readable by visitors with low vision.
ARIA labels presence and validity
Interactive elements have proper ARIA labels — screen reader users get a clear description of each control.
A skip-to-content link is published — keyboard users land directly on the main content.
