calcas.com website review

9 images could be 3.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

About 513 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 290 ms faster on a phone.

7 long tasks block the main thread while loading, the longest for 431 ms. During a long task the page ignores taps.

Polyfills for old browsers add 16 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 12 KiB of CSS is downloaded but never applied on this page.

Your largest element takes 4.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Teacher in class room, one of our hero's.”.

Scripts block taps and scrolling for 567 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 4.9 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 141 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.9 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.8 MB in 59 requests on a phone: images 5.3 MB (22), scripts 397 KiB (33) and HTML 115 KiB (1). Under 2 MB keeps phones on slow connections fast.

2 images weigh 3.1 MB together. On a phone connection a single image that size takes seconds.

2 images are downloaded at several times the size a phone draws them, for example Guaranteed-Repair-Network.png at 1,700 px wide, shown at 380 px. Resized copies would save about 1.2 MB.

2 images (3.1 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

3 images further down the page (3.1 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

FFCarouselgrad-optimized-2.avif is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 1.66 g of CO₂e: 199.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

There are 2 <h1> headlines (“We Do More for the People Who Give More” and “We Do More for the People Who Give More”). One clear main headline is easier for people and search engines.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

2 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 13 pages on calcas.com and 0 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.

The HTML your server sends has 221 of the 528 words a browser shows. AI crawlers don't run JavaScript, so they miss the rest.

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.

/get-a-quote and /customer-service use the same meta description. A description written for each page earns more clicks.

/get-a-quote has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

/claims and /customer-service took over 3 s to send their HTML from our server.

We fetched 7 pages linked from your homepage and read each the way a search engine does.

5 of 21 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

Large scripts ship without source maps.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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

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

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

calcas.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.

calcas.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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust 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 528 words of visible text.

DMARC is set to p=none, so mail pretending to be calcas.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.

Opening the homepage sets 1 cookie (measured from a US location before any click).

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.
