Speed

8 to fix54
  • Improve image delivery

    10.7 s · 3.5 MB

    2 images could be 3.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 10.7 s faster on a phone.

  • Reduce unused JavaScript

    3.8 s · 790 KiB

    About 790 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.8 s faster on a phone.

  • Render-blocking requests

    1.9 s

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

  • Use efficient cache lifetimes

    1.5 s · 301 KiB

    3 files are served with short cache lifetimes, so returning visitors download them again (301 KiB).

  • Main-thread work: 9.6 s

    A phone's processor spends 9.6 s on main-thread work while loading, 2.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • Mobile performance score: 54

    54/100

    Your mobile performance score is 54 (desktop: 67). Pages that score under 90 lose visitors before the first paint.

  • Legacy JavaScript

    350 ms · 47 KiB

    Polyfills for old browsers add 47 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

  • Google Tag Manager adds 232 ms

    232 ms

    Google Tag Manager costs a phone 232 ms of main-thread work and 296 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.

  • 6 third-party services on the page

    6 third-party services load with your homepage (Google Tag Manager, Facebook and Amazon Web Services and others), adding 754 KiB and 470 ms of main-thread time.

  • 9 long tasks on the main thread

    9 long tasks block the main thread while loading, the longest for 158 ms. During a long task the page ignores taps.

  • Reduce unused CSS

    140 ms · 17 KiB

    About 17 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 140 ms faster on a phone.

  • 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.

1 checks passed
  • Server response: 2 ms

    2 ms

    Your server sent the HTML in 2 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix63
  • Largest Contentful Paint: 21.7 s

    21.7 s

    Your largest element takes 21.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • Time to Interactive: 21.7 s

    21.7 s

    The page becomes fully interactive after 21.7 s. Good is under 3.8 s.

  • First Contentful Paint: 6.2 s

    6.2 s

    The first text or image appears after 6.2 s on a phone. Good is under 1.8 s.

  • Speed Index: 8.2 s

    8.2 s

    Visually, the page fills in at 8.2 s (Speed Index). Good is under 3.4 s.

  • Total Blocking Time: 219 ms

    219 ms

    Scripts block taps and scrolling for 219 ms in total while the page loads. Good is under 200 ms.

  • Largest content (LCP) held steady for real visitors

    -1%

    Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 5.7 s to 6.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • 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.

1 checks passed
  • Cumulative Layout Shift: 0

    0

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

Images and page weight

4 to fix25
  • Page weight: 5.5 MB in 24 requests

    5.5 MB

    Your homepage downloads 5.5 MB in 24 requests on a phone: images 4.0 MB (3), scripts 1.3 MB (8) and fonts 122 KiB (5). Under 2 MB keeps phones on slow connections fast.

  • 2 images over 500 KB

    2 images weigh 3.7 MB together. On a phone connection a single image that size takes seconds.

  • 2 images far larger than shown

    1.3 MB

    2 images are downloaded at several times the size a phone draws them, for example hero-bg-tXKcnc8U.jpg at 1,536 px wide, shown at 390 px. Resized copies would save about 1.3 MB.

  • 3 images in older formats

    3 images (4.0 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.

  • About 1.6 g of CO₂ per visit

    1.55 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.55 g of CO₂e: 186.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed
  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

Accessibility

2 to fixGoogle 9898
  • All page content should be contained by landmarks (4 elements)

    All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

  • Heading levels should only increase by one (1 element)

    Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

1 checks passed
  • 39 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 41 WCAG 2.2 A/AA and best-practice rules on the phone render: 39 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

3 to fixGoogle 10084
  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • No canonical URL

    No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

  • Only 0 internal links

    The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

6 checks passed
  • Meta description: 99 characters

    Your meta description is 99 characters: “Three decades of research focused on the question that drives your business: why customers say yes.”.

  • Title: 51 characters

    Your title is a healthy 51 characters: “MECLABS — Research Institute for Conversion Science”.

  • Structured data in place

    Structured data found: Organization and WebSite.

  • 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://meclabs.com/sitemap.xml.

AI search readiness

2 to fix63
  • Most text only appears after JavaScript runs

    0%

    A phone browser shows 1,009 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

  • Organization data is thin (3 of 6 facts)

    Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

  • llms.txt published

    The site publishes https://meclabs.com/llms.txt (2 KiB, 0 links), a plain-text guide to the site for AI tools.

Best practices

Google 96100
  • Missing source maps

    Large scripts ship without source maps.

2 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

4 to fix30
  • 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 calls to action

    We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

  • 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.

  • 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 1,009 words of copy

    The homepage carries about 1,009 words of visible text.

1 checks passed
  • Analytics in place

    Analytics detected: Google Tag Manager and Meta Pixel.

Privacy and tracking

1 to fix
  • 4 trackers load before any consent

    4

    Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity (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.

  • 5 cookies set on arrival

    5

    Opening the homepage sets 5 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.

  • 13 other companies contacted

    Loading the homepage contacts 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

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 meclabs.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
