1 image further down the page (25 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.25 g of CO₂e: 30.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Some list items are not inside a list.

The document uses <meta http-equiv="refresh"> (1 element).

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 8 elements on the page fail this check, rated minor by axe-core.

Google's crawler is blocked from indexing this page.

The page answers with an error status, so search engines may drop it.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

There are 5 <h1> headlines (“15% off laminating bundles!”, “Get ready, get set, go back to school!” and “Save time and money.”). One clear main headline is easier for people and search engines.

The homepage links to 126 pages on gbc.com and 16 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

We fetched 15 pages linked from your homepage (of 96 found) and read each the way a search engine does.

19 of 33 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Uncaught TypeError: Cannot read properties of undefined (reading 'addEventListener')”.

15 links from your homepage to your own site are broken, for example https://www.gbc.com/c/laminating/laminating-machines/ (404).

HSTS is set, but max-age is 30 days; one year is the recommended minimum.

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

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

gbc.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.

gbc.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 419 words of visible text.

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

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.

Before a visitor clicks anything, the page loads Google Ads and Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 24 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
