## WSG Success Criteria & Best Practices

- Assessed pages: 100
- Average WSG compliance score: 85/100

### [MEDIUM] [SCRIPT] Incomplete media lazy loading
Only 11/14 images use loading="lazy". Global lazy loading reduces initial data transfer and energy consumption.
- Recurs on 100 page(s).

**Best Practice Example:**
```javascript
<picture> 
  <source type="image/avif" srcset="image.avif">
  <source type="image/webp" srcset="image.webp">
  <img width="100px" height="100px" src="image.jpg" alt="" loading="lazy"/>
</picture>
```
- [WSG Guideline 11](https://www.w3.org/TR/web-sustainability-guidelines/#optimize-media-to-reduce-resource-use)

### [INVESTIGATE] [HUMAN] Review User Journey Efficiency
Have a human walk through the main user journeys and verify they require the fewest steps possible. Unnecessary steps waste user time and device energy. Look for redundant confirmations, forced account creation, and non-essential interstitials.
- Recurs on 100 page(s).
- [WSG 2.4 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#minimize-non-essential-content-interactivity-or-journeys)

### [INVESTIGATE] [HUMAN] Check for Engagement Traps
Manually review the page for patterns that artificially prolong engagement: infinite scroll, autoplay carousels, sticky overlays, and notification permission prompts. These waste user attention and device energy.
- Recurs on 100 page(s).
- [WSG 2.6 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#design-to-assist-and-not-to-distract)

### [INVESTIGATE] [HUMAN] Audit for Deceptive Design Patterns
Have a human identify dark patterns: misleading consent dialogs, hidden unsubscribe links, forced continuity, and bait-and-switch flows. Deceptive patterns waste user time and undermine trust.
- Recurs on 100 page(s).
- [WSG 2.7 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#avoid-being-manipulative-or-deceptive)

### [INVESTIGATE] [HUMAN] Verify Accessible Alternatives for All Media
Manually check that every video has captions, every audio file has a transcript, every image has meaningful alt text, and every PDF has an accessible HTML alternative. Alternatives let assistive technology users avoid re-downloading heavy formats.
- Recurs on 100 page(s).
- [WSG 2.14 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#offer-suitable-alternatives-for-every-format-used)

### [INVESTIGATE] [HUMAN] Confirm User Research Was Conducted
Verify that genuine user research or usability testing has informed the design. Research-driven design reduces wasted iterations, removes unnecessary features, and ensures the product meets real needs efficiently.
- Recurs on 100 page(s).
- [WSG 2.18 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#involve-users-early-in-the-project)

### [INVESTIGATE] [AI] Review Content Conciseness
Use a Large Language Model (e.g. locally or via API) to evaluate page text for conciseness and clarity. Removing superfluous text reduces payload, reading time, and inference energy for search engines indexing this content.
- Recurs on 100 page(s).
- [WSG 2.10 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#provide-clear-inclusive-content-with-purpose)

### [INVESTIGATE] [HUMAN] Verify Error Pages and Redirects Are Configured
Have a human check that custom 404 and 500 error pages exist and that there are no redirect chains longer than one hop. Broken links force wasted round-trips. Redirect chains multiply transfer costs.
- Recurs on 100 page(s).
- [WSG 4.4 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#setup-necessary-error-pages-and-redirection-links)

### [INVESTIGATE] [HUMAN] Review CDN Usage and Geographic Distribution
Confirm that static assets are served from a CDN and that the CDN edge nodes are geographically close to the primary audience. CDN misuse—or absence—increases last-mile transfer distance and the associated energy cost of data delivery.
- Recurs on 100 page(s).
- [WSG 4.10 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#use-content-delivery-networks-cdns-appropriately)

### [INVESTIGATE] [HUMAN] Confirm a Sustainability Advocate Is Assigned
Verify that someone on the team has explicit responsibility for web sustainability. Without a designated advocate, sustainability improvements tend to be deprioritized and never reach the backlog.
- Recurs on 100 page(s).
- [WSG 5.2 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#assign-a-sustainability-advocate)

### [INVESTIGATE] [HUMAN] Check for a Public Sustainability Statement
Look for a publicly accessible sustainability statement, disclosure page, or environmental policy. Mandatory disclosure requirements are growing globally and transparency builds user trust. The statement should include measurable targets and dates.
- Recurs on 100 page(s).
- [WSG 5.8 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#support-mandatory-disclosures-and-reporting)

### [LOW] [SCRIPT] No reduced motion support
Implement prefers-reduced-motion to allow users to disable animations, reducing compute and improving accessibility.
- Recurs on 5 page(s).

**Best Practice Example:**
```javascript
@media (prefers-reduced-motion: reduce) {
	body *,
	body *::before,
	body *::after {
		animation-delay: -1ms !important;
		animation-duration: 1ms !important;
		animation-iteration-count: 1 !important;
		background-attachment: initial !important;
		transition-duration: 1ms !important;
		transition-delay: -1ms !important;
		scroll-behavior: auto !important;
	}
}
```
- [WSG Guideline 12](https://www.w3.org/TR/web-sustainability-guidelines/#ensure-animation-is-proportionate-and-easy-to-control)

### [MEDIUM] [SCRIPT] Missing main content landmark
No <main> or role="main" tags found. Semantic HTML reduces code bloat and allows both assistive technology and web crawlers to parse content more efficiently.
- Recurs on 2 page(s).
- [WSG 3.7 Reference](https://www.w3.org/TR/web-sustainability-guidelines/#ensure-code-follows-good-semantic-practices)

### [LOW] [SCRIPT] Missing print style sheet
Add a @media print stylesheet to ensure the page is optimized for paper-saving printing.
- Recurs on 1 page(s).

**Best Practice Example:**
```javascript
// Implementation details in documentation
```
- [WSG Guideline 17](https://www.w3.org/TR/web-sustainability-guidelines/#reduce-the-impact-of-downloadable-and-physical-documents)

## WSG Modularization Analysis

- WSG reference: Modularize bandwidth-heavy components (https://www.w3.org/TR/web-sustainability-guidelines/#modularize-bandwidth-heavy-components)
- Modularization score: 0 (few obvious on-demand opportunities) to 100 (many heavy initial-load components)
- This analysis looks for heavy scripts, images, styles, fonts, and media that should be split or loaded on demand.

## Cross-Page Patterns

- This same heavy image pattern appears on 13 pages. Fix it once in the shared template, CMS block, or design system component to reduce load across the whole site.
- These 3 script bundles are recurring modularization targets. Move the fix to the shared bundle or component boundary so every affected page gets lighter at once.
- These 3 modularization targets recur across multiple pages. Centralize the fix at the component or bundle level instead of treating each page separately.
- Heavy assets from www.w3.org recur across 16 pages. Review whether that dependency should be deferred, optimized, or loaded conditionally.

    - Keep only above-the-fold resources in the initial path; hydrate or import secondary modules later.
- Third-party JS recommendations:
  - [LOW] No major third-party JavaScript risk signals
    - Continue periodic reviews so third-party additions are assessed with the same rigor as first-party code.
- Dead-code recommendations:
  - [MEDIUM] Remove unused CSS selectors and component styles (est. 34.78 KB savings)
    - Trim styles that never match rendered markup and split component CSS so only used styles are shipped.
- Non-critical loading candidates:
  - [MEDIUM] Inline critical CSS and defer remainder (est. 34.78 KB deferrable)
    - Ship only above-the-fold CSS in initial render path and defer non-critical styles.
  - [HIGH] Eliminate render-blocking resources (est. 1216 ms unblock)

  - [LOW] No major form validation risks detected
    - Continue testing form flows to ensure error handling remains clear across templates.
- Metadata recommendations:
  - [MEDIUM] Add canonical URL metadata
    - Use rel=canonical to reduce duplicate URL ambiguity for crawlers and tooling.
- Layout adaptation recommendations:
  - [HIGH] Increase touch target sizes
    - Ensure interactive controls are at least 44x44 CSS px. Detected 26 small targets on mobile and 26 on tablet.
- Lightweight security recommendations:
  - [LOW] Define a Referrer-Policy
    - Set a referrer policy to reduce unnecessary URL data leakage.
  - [LOW] Define a Permissions-Policy
    - Restrict browser capabilities to only what the application needs.
- Dependency maintenance recommendations:
  - [LOW] No dependency maintenance warnings detected
    - No vulnerable dependency flags were found for this page in the current lightweight checks.
- Language/runtime version recommendations:
  - [LOW] No obvious outdated runtime version disclosed
    - No clearly outdated runtime version signals were exposed in sampled HTTP headers. Verify language/runtime versions in source and CI since backend versions are not always externally visible.
- Expected-files recommendations:

    - Keep only above-the-fold resources in the initial path; hydrate or import secondary modules later.
- Third-party JS recommendations:
  - [LOW] No major third-party JavaScript risk signals
    - Continue periodic reviews so third-party additions are assessed with the same rigor as first-party code.
- Dead-code recommendations:
  - [MEDIUM] Remove unused CSS selectors and component styles (est. 35.05 KB savings)
    - Trim styles that never match rendered markup and split component CSS so only used styles are shipped.
- Non-critical loading candidates:
  - [MEDIUM] Inline critical CSS and defer remainder (est. 35.05 KB deferrable)
    - Ship only above-the-fold CSS in initial render path and defer non-critical styles.
  - [HIGH] Eliminate render-blocking resources (est. 1202 ms unblock)
    - Defer scripts/styles not required for first paint and preload only truly critical assets.
- Form validation recommendations:
  - [LOW] No major form validation risks detected
    - Continue testing form flows to ensure error handling remains clear across templates.
- Metadata recommendations:
  - [MEDIUM] Add canonical URL metadata
    - Use rel=canonical to reduce duplicate URL ambiguity for crawlers and tooling.
- Layout adaptation recommendations:
  - [MEDIUM] Increase touch target sizes
    - Ensure interactive controls are at least 44x44 CSS px. Detected 13 small targets on mobile and 16 on tablet.
- Lightweight security recommendations:
  - [LOW] Define a Referrer-Policy
    - Set a referrer policy to reduce unnecessary URL data leakage.
  - [LOW] Define a Permissions-Policy
    - Restrict browser capabilities to only what the application needs.
- Dependency maintenance recommendations:
  - [LOW] No dependency maintenance warnings detected
    - No vulnerable dependency flags were found for this page in the current lightweight checks.

    - Confirm this asset is required for first paint; defer or lazy-load if not critical.
  - [HIGH] Evaluate deferred loading for heavy script from www.youtube.com (est. 184.37 KB deferrable)
    - Confirm this asset is required for first paint; defer or lazy-load if not critical.
- Form validation recommendations:
  - [LOW] No major form validation risks detected
    - Continue testing form flows to ensure error handling remains clear across templates.
- Metadata recommendations:
  - [MEDIUM] Add canonical URL metadata
    - Use rel=canonical to reduce duplicate URL ambiguity for crawlers and tooling.
- Layout adaptation recommendations:
  - [HIGH] Increase touch target sizes
    - Ensure interactive controls are at least 44x44 CSS px. Detected 21 small targets on mobile and 21 on tablet.
- Lightweight security recommendations:
  - [LOW] Define a Referrer-Policy
    - Set a referrer policy to reduce unnecessary URL data leakage.
  - [LOW] Define a Permissions-Policy
    - Restrict browser capabilities to only what the application needs.
- Dependency maintenance recommendations:
  - [LOW] No dependency maintenance warnings detected
    - No vulnerable dependency flags were found for this page in the current lightweight checks.
- Language/runtime version recommendations:
  - [LOW] No obvious outdated runtime version disclosed
    - No clearly outdated runtime version signals were exposed in sampled HTTP headers. Verify language/runtime versions in source and CI since backend versions are not always externally visible.
- Expected-files recommendations:
  - [MEDIUM] Add beneficial discoverability and maintenance files
    - Missing beneficial file(s): /sitemap.xml, /.well-known/security.txt, /manifest.webmanifest.
- Compression recommendations:
  - [LOW] Minify JavaScript before transfer
    - Minify JS bundles so transport compression produces better results with fewer bytes. Estimated savings: 5.99 KB.
- Optimization recommendations:
  - [LOW] Minify JavaScript
    - Use minified production JS output to reduce payload size. Estimated byte savings: 5.99 KB.
- Offline/caching recommendations:
  - [HIGH] Add service worker support
    - Register a service worker to support resilient caching and offline behavior for key routes.
  - [HIGH] Ensure critical routes work offline
    - Provide an offline fallback strategy for key pages and shell assets.
  - [MEDIUM] Improve web app manifest support
    - Complete manifest fields so clients can install and run an app-like experience.
  - [MEDIUM] Support offline start URL behavior
    - Ensure start URL and shell routing can load in disconnected conditions.
  - [MEDIUM] Strengthen static asset cache TTL
    - Improve long-lived cache headers for immutable static assets (estimated savings opportunity: 145.62 KB).
- Media sustainability recommendations:
  - [MEDIUM] Add dark mode support
    - No prefers-color-scheme: dark media query or color-scheme meta tag was found. Dark mode reduces energy use on OLED screens and improves user choice.
  - [MEDIUM] Add loading="lazy" to images
    - 4 of 6 image(s) lack an explicit loading="lazy" attribute. Lazy loading defers below-fold images and reduces initial page weight.
- Grid-aware websites: not detected
- No high-priority issues flagged by current mapping.
