cid.com website review

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

About 123 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 690 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

The page has 2,562 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 2.0 s on main-thread work while loading, 357 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

2 third-party services load with your homepage (Google Tag Manager and Google Analytics), adding 281 KiB and 231 ms of main-thread time.

3 images could be 235 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

5 long tasks block the main thread while loading, the longest for 104 ms. During a long task the page ignores taps.

1 file is served with short cache lifetimes, so returning visitors download them again (16 KiB).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

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

Your largest element takes 13.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies for statistical purposes to better understan…”.

The page becomes fully interactive after 13.9 s. Good is under 3.8 s.

Real visitors wait 2.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 138 ms to 135 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.6 MB in 67 requests on a phone: images 1.6 MB (34), fonts 606 KiB (3) and scripts 355 KiB (17). Under 2 MB keeps phones on slow connections fast.

1 image (35 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.74 g of CO₂e: 89.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 33 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

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

The homepage links to 103 pages on cid.com and 6 external pages.

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.

/why-cid/our-advantage has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 45 found) and read each the way a search engine does.

2 of 10 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 “vMapLocationData is not defined”.

4 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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.

cid.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.

Social proof on the homepage: 8 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,657 words of visible text.

cid.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 Analytics, Google Tag Manager, HubSpot and LinkedIn Insight (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.

Opening the homepage sets 4 cookies (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.

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
