Speed

100
  • Reduce unused CSS

    42 KiB

    About 42 KiB of CSS is downloaded but never applied on this page.

  • Improve image delivery

    32 KiB

    2 images could be 32 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Chained critical requests

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

  • Forced reflow

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

  • 2 third-party services on the page

    2 third-party services load with your homepage (JSDelivr CDN and Cloudflare CDN), adding 13 KiB and 3 ms of main-thread time.

  • Use efficient cache lifetimes

    1 KiB

    2 files are served with short cache lifetimes, so returning visitors download them again (1 KiB).

3 checks passed
  • Mobile performance score: 100

    100/100

    Your mobile performance score is 100. That is in Google's “good” band (90 and up).

  • Main-thread work: 0.5 s

    A phone's processor spends 0.5 s on main-thread work while loading, 26 ms of it running JavaScript. That is comfortably low.

  • Server response: 136 ms

    136 ms

    Your server sent the HTML in 136 ms, well inside Google's 600 ms guideline.

Core Web Vitals

3 to fix100
  • Fails Core Web Vitals for real visitors

    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.

  • Real-user TTFB: 801 ms

    801 ms

    Real visitors wait 801 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • 1 image without width and height

    1 image have no width and height attributes, so the layout jumps as each one loads.

12 checks passed
  • Real-user LCP: 1.5 s

    1.5 s

    Real visitors wait 1.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 96 ms

    96 ms

    Real visitors wait 96 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.2 s

    1.2 s

    Real visitors see the first content after 1.2 s (75th percentile). Good is under 1.8 s.

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

    -20%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 134 ms to 100 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) got 41% faster for real visitors

    -41%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.6 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest Contentful Paint: 1.8 s

    1.8 s

    Your largest element renders in 1.8 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the image.

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

  • First Contentful Paint: 0.9 s

    0.9 s

    The first text or image appears after 0.9 s, inside the 1.8 s “good” threshold.

  • Speed Index: 1.4 s

    1.4 s

    Visually, the page fills in at 1.4 s (Speed Index), inside the 3.4 s “good” threshold.

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

  • Time to Interactive: 1.8 s

    1.8 s

    The page is fully interactive after 1.8 s.

Images and page weight

100
  • About 0.1 g of CO₂ per visit

    0.14 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.14 g of CO₂e: 16.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 checks passed
  • Page weight: 506 KiB in 22 requests

    506 KiB

    Your homepage downloads 506 KiB in 22 requests on a phone: images 410 KiB (16), stylesheets 67 KiB (4) and HTML 28 KiB (1). That is a lean page.

  • 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

5 to fixGoogle 9094
  • 2 text elements with low contrast

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

  • 2 tap targets too small

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

  • All page content should be contained by landmarks (1 element)

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

  • 2 links without text

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

  • 1 form field without a label

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

  • Headings skip levels

    Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

2 checks passed
  • Every image has alt text

    All 46 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 55 WCAG 2.2 A/AA and best-practice rules on the phone render: 50 passed and 5 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 9288
  • Title is short (29 characters)

    Your title is only 29 characters: “Advanced data solutions | C&F”. Between 30 and 65 characters leaves room to say what you do and for whom.

  • No social preview image

    No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

  • 3 links with vague text

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

  • 98 internal links, 4 external

    The homepage links to 98 pages on candf.com and 4 external pages.

6 checks passed
  • Meta description: 129 characters

    Your meta description is 129 characters: “Transform your business with C&F's data-driven solutions. Enhance efficiency, drive growth, and stay competitive. Learn…”.

  • One H1 headline

    Your main headline reads: “Advanced data solutions for business excellence”.

  • Canonical URL set

    The canonical URL is https://candf.com/.

  • Structured data in place

    Structured data found: Organization, WebPage and WebSite.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://candf.com/sitemap_index.xml.

AI search readiness

100
4 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 5 of 6 facts

    Your Organization JSON-LD gives name, url, logo, sameAs (social profiles) and contact details; description would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (705 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes /llms.txt (103 KiB, 316 links, though it should open with a “# Title” line), a plain-text guide to the site for AI tools.

Other pages

1 to fix93
  • 1 linked page hidden from search

    /services-category/it-service-management is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 65 found) and read each the way a search engine does.

6 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Every page has a meta description

    All 15 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

Best practices

2 to fixGoogle 9687
  • 7 small tap targets

    7 of 26 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 1 JavaScript error while loading

    1 error was logged to the browser console while the page loaded, for example “Error with Permissions-Policy header: Parse of permissions policy failed because of errors reported by structured heade…”.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

1 to fix94
  • No Content-Security-Policy

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

  • 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.

7 checks passed
  • Served over HTTPS

    The homepage is served over HTTPS (candf.com).

  • Valid certificate (76 days left)

    The certificate from Let's Encrypt · YR2 verifies for candf.com and is valid for another 76 days.

  • Protected from clickjacking

    X-Frame-Options or a frame-ancestors policy stops other sites framing yours.

  • HSTS enabled

    Strict-Transport-Security is set, so browsers always use https.

  • http:// redirects to https

    http://candf.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.

  • All 44 links work

    All 44 links checked from your homepage (40 internal, 4 external) answered without errors.

Domain and trust

  • No CAA record

    candf.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.

3 checks passed
  • Domain is 31 years old

    31 years

    candf.com was registered in May 1995 through Key-Systems GmbH. An established domain carries more trust with email providers and search engines.

  • DNSSEC is on

    candf.com's DNS answers are signed (DNSSEC), so they can't be forged on the way to visitors.

  • Registered until May 2027

    candf.com is registered until May 2027.

Content and conversion

2 to fix88
  • 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: 8 customer or partner logos. 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 684 words of copy

    The homepage carries about 684 words of visible text.

6 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Download the guide”.

  • 6 calls to action

    The homepage has 6 calls to action, for example “Join Us”, “Contact us” and “Download the guide”.

  • 2 short forms

    2 short forms (1 field at most) are right on the homepage.

  • Analytics in place

    Analytics detected: Google Tag Manager.

  • Direct contact links

    Visitors can reach you directly: 4 phone links and 1 email link.

  • Phone number on the homepage

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

Email authentication

90
  • Email authentication score: 90/100

    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.

3 checks passed
  • DMARC policy: quarantine

    DMARC tells receivers to quarantine mail that fails authentication, and sends you reports.

  • SPF with a strict ending (-all)

    An SPF record lists your sending servers and tells receivers to reject anything else: “v=spf1 include:spf.protection.outlook.com a:cloudserver3222233-3222264.home.pl a mx -all”.

  • DKIM signing found

    A DKIM key is published (selector “selector1”, “selector2” and “k2”), so receivers can verify mail really came from you.

Privacy and tracking

  • 3 trackers load before any consent

    3

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

  • 2 cookies set on arrival

    2

    Opening the homepage sets 2 cookies (measured from a US location before any click).

  • 16 other companies contacted

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

1 checks passed
  • Consent tool: Cookiebot

    A consent management tool (Cookiebot) loads with the page.
