Website Performance & Accessibility Audit Report

Date: 2025-11-19 Site: https://unity-lab-ai.github.io/sitetest0/ Audit Type: Manual Code Review Pages Audited: index.html, about/index.html, services/index.html, projects/index.html, contact/index.html

Executive Summary

Overall Assessment: The website is functional but has significant performance and accessibility issues that need immediate attention.

Scores (Estimated):

  • Performance: ~60/100 ⚠️
  • Accessibility: ~45/100 ❌ CRITICAL
  • Best Practices: ~75/100 🟡
  • SEO: ~80/100 ✓

🔴 CRITICAL ISSUES (Must Fix Immediately)

1. Form Accessibility Violations (WCAG 2.1 Level A Failure)

Severity: CRITICAL Impact: Screen readers cannot identify form fields

Issues:

  • ✗ NO <label> elements for any form inputs across all pages
  • ✗ Forms use placeholders instead of labels (WCAG 3.3.2 violation)
  • ✗ No ARIA labels as fallback
  • ✗ Screen reader users cannot complete forms

Affected Pages:

  • /contact/index.html - Main contact form (8 fields without labels)
  • /about/index.html - About contact form
  • /services/index.html - Services contact form

Example Issue:

<!-- WRONG: No label -->
<input type="text" id="contactName" class="form-control" placeholder="Your Name" required>

<!-- CORRECT: -->
<label for="contactName">Your Name</label>
<input type="text" id="contactName" class="form-control" placeholder="Enter your name" required>

Fix Priority: P0 (Immediate)

2. Cache Headers Force No-Cache

Severity: CRITICAL for Performance Impact: Users re-download all assets on every visit

Issue:

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">

These headers completely disable browser caching, forcing users to download:

  • 38KB styles.css on every page load
  • 44KB script.js on every page load
  • All Bootstrap CSS (>50KB) on every load
  • All Font Awesome CSS (~70KB) on every load

Impact: Estimated 200KB+ extra download per page view

Recommendation: Remove these meta tags entirely. Cache-busting is already handled via ?v=bf4cb6a query strings.

Fix Priority: P0 (Immediate)

⚠️ HIGH PRIORITY ISSUES

3. Unminified CSS and JavaScript

Severity: HIGH Impact: Slower page loads, higher bandwidth usage

Current:

  • styles.css: 38KB (1,742 lines)
  • script.js: 44KB (1,297 lines)

Potential Savings:

  • CSS minification: ~25-30% reduction = ~10-12KB saved
  • JS minification: ~30-40% reduction = ~13-18KB saved
  • Total potential savings: ~25-30KB per page load

Fix Priority: P1

4. Render-Blocking Resources

Severity: HIGH Impact: Slower First Contentful Paint (FCP)

Issues:

  • AOS animation CSS loaded in <body> footer (line 262) - should be in <head>
  • Bootstrap CSS is render-blocking (expected, but could extract critical CSS)
  • Font Awesome CSS is render-blocking

Current Load Order:

  1. HTML parsed
  2. Bootstrap CSS downloaded (blocks rendering)
  3. Font Awesome CSS downloaded (blocks rendering)
  4. Custom CSS downloaded
  5. Body renders
  6. AOS CSS downloaded (causes layout shift)

Recommendation:

  • Move AOS CSS to <head>
  • Extract critical above-the-fold CSS
  • Defer non-critical CSS

Fix Priority: P1

5. No ARIA Attributes

Severity: HIGH Impact: Reduced screen reader usability

Issues:

  • No ARIA landmarks (role="navigation", role="main", etc.)
  • No aria-label for icon-only buttons
  • No aria-expanded for navbar toggle
  • No aria-live regions for dynamic content

Examples:

<!-- Current -->
<nav class="navbar navbar-expand-lg navbar-dark fixed-top">

<!-- Better -->
<nav class="navbar navbar-expand-lg navbar-dark fixed-top" role="navigation" aria-label="Main navigation">

Fix Priority: P1

🟡 MEDIUM PRIORITY ISSUES

6. Color Contrast Concerns

Severity: MEDIUM Impact: Users with visual impairments may struggle to read text

Potential Issues Identified:

  • Light grey text (#cccccc) on dark backgrounds
  • Crimson red (#dc143c) on dark backgrounds
  • Need to verify all combinations meet WCAG AA (4.5:1 for normal text)

Colors Used:

  • Background: Near black (#0a0a0a, #1a1a1a)
  • Text: Light grey (#cccccc), White (#ffffff)
  • Accents: Crimson red (#dc143c), Bright red (#ff0033)

Action Required: Test all text/background combinations with contrast checker

Fix Priority: P1

7. Missing Semantic HTML Elements

Severity: MEDIUM Impact: SEO and accessibility

Issues:

  • No <main> element to identify main content
  • No <article> or <section> semantic tags with proper structure
  • Generic <div> containers where semantic elements would be better

Fix Priority: P2

8. External Resource Performance

Severity: MEDIUM Impact: Additional network requests

External Resources Loaded:

  • Bootstrap CSS (~50-60KB)
  • Bootstrap JS (~80KB)
  • Font Awesome CSS (~70KB)
  • AOS CSS (~5KB)
  • AOS JS (~15KB)

Total External: ~220-230KB

Good Practices Already Implemented: ✓ Preconnect to cdn.jsdelivr.net and cdnjs.cloudflare.com ✓ SRI integrity hashes for security ✓ CDN caching benefits

Recommendation: Consider bundling or self-hosting for better control

Fix Priority: P2

📊 SEO ISSUES

9. Missing Open Graph Images

Severity: MEDIUM Impact: Poor social media sharing appearance

Missing:

  • og:image
  • og:title
  • og:description
  • og:url
  • Twitter card meta tags

Fix Priority: P1

10. Missing Sitemap and Robots.txt

Severity: LOW Impact: Reduced search engine crawling efficiency

Missing:

  • /sitemap.xml
  • /robots.txt

Fix Priority: P2
