Speed

8 to fix47
  • Reduce unused JavaScript

    1.8 s · 658 KiB

    About 658 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

  • Mobile performance score: 47

    47/100

    Your mobile performance score is 47. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

  • Main-thread work: 4.1 s

    A phone's processor spends 4.1 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, transcend-cdn.com and Hotjar and others), adding 643 KiB and 1.3 s of main-thread time.

  • Google Tag Manager adds 656 ms

    656 ms

    Google Tag Manager costs a phone 656 ms of main-thread work and 321 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • Render-blocking requests

    500 ms

    2 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

  • transcend-cdn.com adds 347 ms

    347 ms

    transcend-cdn.com costs a phone 347 ms of main-thread work and 160 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • 18 long tasks on the main thread

    18 long tasks block the main thread while loading, the longest for 349 ms. During a long task the page ignores taps.

  • Legacy JavaScript

    150 ms · 48 KiB

    Polyfills for old browsers add 48 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

  • Use efficient cache lifetimes

    165 KiB

    6 files are served with short cache lifetimes, so returning visitors download them again (165 KiB).

  • 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.

1 checks passed
  • Server response: 3 ms

    3 ms

    Your server sent the HTML in 3 ms, well inside Google's 600 ms guideline.

Core Web Vitals

4 to fix100
  • Largest Contentful Paint: 6.6 s

    6.6 s

    Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • Total Blocking Time: 1.6 s

    1.6 s

    Scripts block taps and scrolling for 1.6 s in total while the page loads. Good is under 200 ms.

  • Time to Interactive: 11.9 s

    11.9 s

    The page becomes fully interactive after 11.9 s. Good is under 3.8 s.

  • Speed Index: 5.1 s

    5.1 s

    Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

10 checks passed
  • Passes Core Web Vitals for real visitors

    Real Chrome users on phones pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)).

  • Real-user LCP: 2.5 s

    2.5 s

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

  • Real-user INP: 187 ms

    187 ms

    Real visitors wait 187 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: 1.5 s

    1.5 s

    Real visitors see the first content after 1.5 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 691 ms

    691 ms

    Real visitors wait 691 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • Tap response (INP) got 47% faster for real visitors

    -47%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 387 ms to 190 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) got 35% faster for real visitors

    -35%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.1 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Cumulative Layout Shift: 0

    0

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

  • First Contentful Paint: 1.1 s

    1.1 s

    The first text or image appears after 1.1 s, inside the 1.8 s “good” threshold.

Images and page weight

1 to fix85
  • Page weight: 2.4 MB in 102 requests

    2.4 MB

    Your homepage downloads 2.4 MB in 102 requests on a phone: scripts 1.6 MB (54), other files 720 KiB (36) and fonts 101 KiB (7). Under 2 MB keeps phones on slow connections fast.

  • About 0.7 g of CO₂ per visit

    0.69 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.69 g of CO₂e: 83.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • 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

1 to fixGoogle 9398
  • 1 button without a name

    1 button has no accessible name, so screen readers announce just “button”.

  • Headings skip levels

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

1 checks passed
  • 40 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 42 WCAG 2.2 A/AA and best-practice rules on the phone render: 40 passed and 2 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 10089
  • Title is short (5 characters)

    Your title is only 5 characters: “Accel”. Between 30 and 65 characters leaves room to say what you do and for whom.

  • No structured data

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

  • 8 internal links, 5 external

    The homepage links to 8 pages on accel.com and 5 external pages.

6 checks passed
  • Meta description: 120 characters

    Your meta description is 120 characters: “Accel is a leading venture capital firm that has invested in over 300 companies, including Facebook, Slack, and Dropbox.”.

  • One H1 headline

    Your main headline reads: “First partner to exceptional teams everywhere”.

  • Canonical URL set

    The canonical URL is https://www.accel.com/index.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • 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://accel.com/sitemap.xml.

AI search readiness

1 to fix83
  • No Organization structured data

    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.

  • No llms.txt

    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.

1 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.

Other pages

2 to fix93
  • 4 pages share a meta description

    /companies, /team, /news and /contact-us use the same meta description. A description written for each page earns more clicks.

  • 3 pages without an H1

    /companies, /team and /news have no <h1> headline, so visitors and search engines get no clear main topic.

  • 2 pages with very little text

    /companies and /contact-us have 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.

  • 4 internal pages checked

    We fetched 4 pages linked from your homepage and read each the way a search engine does.

6 checks passed
  • Linked pages load

    All 4 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 4 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 4 pages that loaded have a <title>.

Best practices

1 to fixGoogle 9293
  • 2 JavaScript errors while loading

    2 errors were logged to the browser console while the page loaded, for example “The Content Security Policy directive 'upgrade-insecure-requests' is ignored when delivered in a report-only policy.”.

  • Browser-reported issues

    Chrome logged issues while loading the page (“Content security policy”).

2 checks passed
  • Tap targets are thumb-sized

    14 of 15 tappable elements near the top are at least 24 px.

  • 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.

  • 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 (accel.com).

  • Valid certificate (54 days left)

    The certificate from Let's Encrypt · YR1 verifies for accel.com and is valid for another 54 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://accel.com redirects to the secure version.

  • HTTP/2

    The server speaks HTTP/2, so browsers load many files over one connection.

  • All 10 links work

    All 10 links checked from your homepage (5 internal, 5 external) answered without errors.

Domain and trust

4 checks passed
  • Domain is 35 years old

    35 years

    accel.com was registered in Apr 1991 through Network Solutions, LLC. An established domain carries more trust with email providers and search engines.

  • Certificate issuers are restricted

    CAA records allow only globalsign.com, letsencrypt.org, pki.goog and sectigo.com to issue certificates for accel.com, so a mis-issued certificate from anyone else is refused.

  • DNSSEC is on

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

  • Registered until Apr 2028

    accel.com is registered until Apr 2028.

Content and conversion

5 to fix42
  • No call to action on the first screen

    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 social proof

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

  • No analytics detected

    No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

  • 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.

  • Only about 22 words

    The homepage has only about 22 words of visible text; thin pages give Google and first-time buyers little to go on.

  • No form on the homepage

    There is no form on the homepage, so every lead has to click through to another page first.

  • 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.

1 checks passed
  • 1 call to action

    The homepage has 1 call to action, for example “Contact Us”.

Email authentication

85
  • Email authentication score: 85/100

    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 in place (~all)

    An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 include:accel.com._nspf.vali.email include:%{i}._ip.%{h}._ehlo.%{d}._spf.vali.email ~all”.

  • DKIM signing found

    A DKIM key is published (selector “google”, “selector1” and “k1”), so receivers can verify mail really came from you.

Privacy and tracking

  • 2 cookies set on arrival

    2

    Opening the homepage sets 2 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.

  • 2 other companies contacted

    Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed
  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
