One score from every part of this review. How it works
Speed
Google's speed test didn't respond
Google's speed test didn't respond for this site, so speed and Core Web Vitals are not measured here. Your full playbook measures them.
Core Web Vitals
Not measured in this review.
Images and page weight
Page weight: 2.2 MB
2.2 MBYour homepage downloads 2.2 MB on a phone, 294 KiB of it images (13%). Under 2 MB keeps phones on slow connections fast.
About 0.6 g of CO₂ per visit
0.61 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.61 g of CO₂e: 73.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
10 text elements with low contrast
10 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (2 elements)
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.
Banner landmark should not be contained in another landmark (1 element)
Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.
Document should not have more than one banner landmark (1 element)
Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.
6 links without text
6 visible links have no text or label, so screen readers cannot say where they go.
Headings skip levels
Headings skip levels (h1 → h3, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.
2 checks passed
Every image has alt text
All 91 images in the HTML carry an alt attribute.
50 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 56 WCAG 2.2 A/AA and best-practice rules on the phone render: 50 passed and 6 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

Organization data: 6 of 6 facts
Your Organization JSON-LD gives name, url, logo, sameAs (social profiles), description and contact details.
Text is in the HTML
Your server sends the page's text in the HTML (3,384 words), so crawlers that don't run JavaScript still read it.
llms.txt published
The site publishes /llms.txt (11 KiB, 35 links), a plain-text guide to the site for AI tools.
Other pages
2 pages without a meta description
/blog and /ai-search-rank have no meta description, so Google writes the search snippet from whatever text it finds.

Best practices
3 JavaScript errors while loading

2 checks passed
Tap targets are thumb-sized
5 of 6 tappable elements near the top are at least 24 px.
Mobile viewport set
The page declares a mobile viewport.
Security and trust
1 broken external link
1 link to other sites is dead, for example https://www.linkedin.com/in/lillianpierson/ (999).
No HSTS header
No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.
No clickjacking protection
Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.
No X-Content-Type-Options
X-Content-Type-Options: nosniff is missing, so browsers may guess file types.
No Referrer-Policy
No Referrer-Policy header, so full URLs can leak to the sites you link to.
No security.txt
There is no /.well-known/security.txt telling researchers how to report a security problem to you.
5 checks passed
Served over HTTPS
The homepage is served over HTTPS (data-mania.com).
Valid certificate (40 days left)
The certificate from Let's Encrypt · YE1 verifies for data-mania.com and is valid for another 40 days.
Content-Security-Policy set
A Content-Security-Policy is set, the main browser-side defence against injected scripts.
http:// redirects to https
http://data-mania.com redirects to the secure version.
HTTP/2 and HTTP/3
The server speaks HTTP/2 and advertises HTTP/3, so browsers load many files over one connection.
Domain and trust
No CAA record
data-mania.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.
DNSSEC is off
data-mania.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.
2 checks passed
Domain is 13 years old
13 yearsdata-mania.com was registered in Sep 2013 through GoDaddy.com, LLC. An established domain carries more trust with email providers and search engines.
Registered until Sep 2028
data-mania.com is registered until Sep 2028.
Content and conversion
Local business without LocalBusiness data
Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.
Thin social proof
Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.
No opening hours
The homepage shows no opening hours. If customers visit or call, show when.
No map or directions link
There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.
No risk reducer
No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
About 2,492 words of copy
The homepage carries about 2,492 words of visible text.
6 checks passed

Phone number on the homepage
Your phone number is on the homepage as a tap-to-call link.

3 checks passed
DMARC policy: quarantine
DMARC tells receivers to quarantine mail that fails authentication, and sends you reports.
SPF in place (~all)
An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 include:_spf.google.com ~all”.
DKIM signing found
A DKIM key is published (selector “google” and “smtp”), so receivers can verify mail really came from you.
Privacy and tracking
4 trackers load before any consent

16 other companies contacted
