Speed

1 to fix99
  • Render-blocking requests

    750 ms

    2 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

  • 2 third-party services on the page

    2 third-party services load with your homepage (Cloudflare and Google Fonts), adding 97 KiB and 12 ms of main-thread time.

  • Legacy JavaScript

    10 KiB

    Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

  • 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.

  • Use efficient cache lifetimes

    4 KiB

    2 files are served with short cache lifetimes, so returning visitors download them again (4 KiB).

2 checks passed
  • Mobile performance score: 99

    99/100

    Your mobile performance score is 99. That is in Google's “good” band (90 and up).

  • Main-thread work: 0.1 s

    A phone's processor spends 0.1 s on main-thread work while loading, 19 ms of it running JavaScript. That is comfortably low.

Core Web Vitals

100
  • Not enough real-visitor data yet

    Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

6 checks passed
  • First Contentful Paint: 1.5 s

    1.5 s

    The first text or image appears after 1.5 s, inside the 1.8 s “good” threshold.

  • Speed Index: 2.5 s

    2.5 s

    Visually, the page fills in at 2.5 s (Speed Index), inside the 3.4 s “good” threshold.

  • Cumulative Layout Shift: 0.001

    0.001

    The layout barely moves while loading (CLS 0.001, good is under 0.1).

  • Largest Contentful Paint: 1.5 s

    1.5 s

    Your largest element renders in 1.5 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “Long-form writing on distributed systems, storage, compiler…”.

  • 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: 1.5 s

    1.5 s

    The page is fully interactive after 1.5 s.

Images and page weight

100
  • About 0.03 g of CO₂ per visit

    0.03 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.03 g of CO₂e: 3.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed
  • Page weight: 104 KiB in 8 requests

    104 KiB

    Your homepage downloads 104 KiB in 8 requests on a phone: fonts 85 KiB (3), scripts 10 KiB (1) and stylesheets 5 KiB (2). That is a lean page.

Accessibility

1 to fixGoogle 10099
  • Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

    Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

1 checks passed
  • 33 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 34 WCAG 2.2 A/AA and best-practice rules on the phone render: 33 passed and 1 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 10096
  • No social preview image

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

  • No favicon declared

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

  • 31 internal links, 2 external

    The homepage links to 31 pages on slamdata.com and 2 external pages.

7 checks passed
  • Meta description: 112 characters

    Your meta description is 112 characters: “Long-form technical writing on distributed systems, storage, compilers, infrastructure and engineering practice.”.

  • One H1 headline

    Your main headline reads: “How it actually behaves.”.

  • Title: 48 characters

    Your title is a healthy 48 characters: “SlamData — Systems, Compilers and Infrastructure”.

  • Canonical URL set

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

  • Structured data in place

    Structured data found: 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://slamdata.com/sitemap.xml.

AI search readiness

1 to fix88
  • 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 https://slamdata.com/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.

2 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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (334 words), so crawlers that don't run JavaScript still read it.

Other pages

100
  • 13 internal pages checked

    We fetched 13 pages linked from your homepage and read each the way a search engine does.

7 checks passed
  • Linked pages load

    All 13 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

Best practices

1 to fixGoogle 10093
  • 1 JavaScript error while loading

    1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

2 checks passed
  • Tap targets are thumb-sized

    19 of 20 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

3 to fix58
  • 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 direct contact details

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

  • No form on the homepage

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

  • About 334 words of copy

    The homepage carries about 334 words of visible text.

3 checks passed
  • 1 call to action

    The homepage has 1 call to action, for example “Every request will be retried”.

  • Analytics in place

    Analytics detected: Cloudflare Web Analytics.

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Privacy and tracking

  • 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.

  • 3 other companies contacted

    Loading the homepage contacts 3 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).

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at slamdata.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
