Not measured in this review.

• Fails Core Web Vitals for real visitors

  Real Chrome users on phones do not pass Google's Core Web Vitals on your site (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

• Real-user INP: 245 ms

  245 ms

  Real visitors wait 245 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

• Tap response (INP) got 20% slower for real visitors

  +20%

  Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 201 ms to 246 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

• Page weight: 4.1 MB

  4.1 MB

  Your homepage downloads 4.1 MB on a phone, 1.1 MB of it images (27%). Under 2 MB keeps phones on slow connections fast.

• 2 images far larger than shown

  332 KiB

  2 images are downloaded at several times the size a phone draws them, for example IMG_3504.jpg at 1,600 px wide, shown at 194 px. Resized copies would save about 332 KiB.

  Elements (2)

• About 1.2 g of CO₂ per visit

  1.16 g

  By the Sustainable Web Design model, a visit to your homepage emits about 1.16 g of CO₂e: 139.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• 17 text elements with low contrast

  17 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

  Elements (3)

• Scrollable region must have keyboard access (17 elements)

  Scrollable region must have keyboard access: 17 elements on the page fail this check, rated serious by axe-core.

  Elements (3)

• 4 tap targets too small

  4 tap targets are too small or too close together to hit reliably with a finger.

  Elements (3)

• All page content should be contained by landmarks (3 elements)

  All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

  Elements (3)

• 14 links without text

  14 visible links have no text or label, so screen readers cannot say where they go.

  Elements (1)

• 1 form field without a label

  1 form field has no label, so screen readers announce an empty box and autofill guesses.

  View source

• 166 internal links, 4 external

  The homepage links to 166 pages on decarba.com and 4 external pages.

• Organization data is thin (2 of 6 facts)

  Your Organization JSON-LD is missing logo, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

  View source

• 6 pages without a meta description

  /en-us/collections/footwear-sneakers-clogs, /en-us/collections/bf-bestsellers, /en-us/collections/bestsellers-2025, /en-us/collections/all-1, /en-us/collections/bestseller-2026 and /en-us/collections/derbys have no meta description, so Google writes the search snippet from whatever text it finds.

  Elements (6)

• 5 pages without an H1

  /en-us/collections/footwear-sneakers-clogs, /en-us/collections/bf-bestsellers, /en-us/collections/bestsellers-2025, /en-us/collections/all-1 and /en-us/collections/derbys have no <h1> headline, so visitors and search engines get no clear main topic.

• 15 internal pages checked

  We fetched 15 pages linked from your homepage (of 59 found) and read each the way a search engine does.

• 1 broken image

  1 image failed to load on a phone, for example https://files.alia-prod.com/decarbablacklogo.svg-1761941080938.

• 4 JavaScript errors while loading

  4 errors were logged to the browser console while the page loaded, for example “Cannot assign to read only property 'protect' of object '#<Object>'”.

• Short HSTS lifetime

  HSTS is set, but max-age is 91 days; one year is the recommended minimum.

• No Referrer-Policy

  No Referrer-Policy header, so full URLs can leak to the sites you link to.

• No Permissions-Policy

  No Permissions-Policy header to switch off camera, microphone and location for embedded content.

• Deprecated X-XSS-Protection

  X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

• No security.txt

  There is no /.well-known/security.txt telling researchers how to report a security problem to you.

• Domain expires in 70 days

  decarba.com is registered until Jan 2027. Make sure auto-renew is on and the card on file is current.

• No CAA record

  decarba.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

  decarba.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.

• Thin social proof

  Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

• No direct contact details

  No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

• 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 749 words of copy

  The homepage carries about 749 words of visible text.

• Urgency cues

  The page uses urgency cues (a countdown or limited-time wording).

• DMARC is monitor-only (p=none)

  DMARC is set to p=none, so mail pretending to be decarba.com is still delivered. Reports are on, so moving to quarantine is the next step.

• Email authentication score: 75/100

  Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

• 8 trackers load before any consent

  8

  Before a visitor clicks anything, the page loads Google Ads, Google Tag Manager, Klaviyo, Meta Pixel and Microsoft Clarity and 3 mores (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

• 27 cookies set on arrival

  27

  Opening the homepage sets 27 cookies (measured from a US location before any click).

• No consent tool detected

  No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

• 46 other companies contacted

  Loading the homepage contacts 46 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
