WebRank SEO Checklist: Ensuring Visibility in Internet Explorer

Overview

This checklist focuses on maximizing search visibility for sites when accessed with Internet Explorer (IE). While IE usage is low and legacy, some enterprise users and older systems still rely on it. The checklist prioritizes compatibility, performance, and crawlability so your site’s WebRank isn’t harmed for IE visitors or crawlers that emulate IE.

1. Doctype & Document Mode

  • Use a modern doctype: Add <!DOCTYPE html> to avoid IE running in quirks mode.
  • Force edge mode: Include early in the head to ensure IE uses the latest rendering engine available.

2. HTML/CSS Compatibility

  • Avoid deprecated features: Don’t rely on nonstandard IE-only tags or behaviors.
  • Progressive enhancement: Build a semantic core (HTML content + links) that works without advanced CSS.
  • Fallback styles: Provide basic CSS that works in older IE versions (e.g., avoid CSS variables, use feature queries via @supports when possible).
  • Polyfills where needed: Include small polyfills for critical functionality (e.g., Promises, fetch) only when IE must support important UX paths.

3. JavaScript & Rendering

  • Server-side render critical content: Ensure primary content and navigation are server-rendered so search engines and IE users see it without heavy JS.
  • Transpile for IE: If your build uses modern JS (ES6+), transpile and include polyfills so essential scripts run in IE.
  • Avoid blocking rendering: Defer noncritical scripts with defer or load asynchronously.
  • Graceful degradation: Ensure core functionality (links, forms, basic navigation) works if advanced JS fails.

4. Performance & Resource Loading

  • Optimize assets: Minify and compress CSS/JS; serve gzipped or brotli.
  • Use conditional comments sparingly: Only for critical fixes in IE8/9; prefer feature detection.
  • Cache headers: Set proper caching for static resources to reduce load times on legacy devices.
  • Image formats: Provide widely supported formats (JPEG/PNG) and fallbacks for modern formats (WebP).

5. Accessibility & HTML Semantics

  • Semantic structure: Use headings, nav, main, footer so crawlers and readers can parse content.
  • Alt text & labels: Ensure images and form controls have descriptive attributes.
  • Keyboard navigation: Verify tab order and focus styles work in IE.

6. Crawlability & Metadata

  • Robots & sitemap: Ensure robots.txt and XML sitemap are accessible and reference canonical URLs.
  • Correct meta tags: Use proper title, meta description, canonical tags, and hreflang where applicable.
  • Avoid JS-only navigation: Provide crawlable anchor links and server-rendered URLs rather than client-only routing.

7. Structured Data & Rich Results

  • JSON-LD availability: Serve structured data in the page source where possible. If generated by JS, ensure search crawlers can access it (prefer server-rendered).
  • Microdata fallback: If JSON-LD is injected via JS, include critical structured snippets in HTML for legacy agents.

8. Security & HTTPS

  • HTTPS everywhere: Serve content over HTTPS with modern TLS; check that IE versions in use accept your TLS configuration.
  • HSTS caution: Use HSTS carefully if supporting very old IE clients that may choke on strict policies.

9. Testing & Monitoring

  • Test in IE versions used by your audience: Use real devices, virtual machines, or BrowserStack.
  • Automated checks: Include IE-compatible builds in CI and run accessibility and SEO linters.
  • Analytics segmentation: Track visits from IE and monitor bounce/engagement to detect regressions.

10. When to Drop IE Support

  • Cost vs. value: If IE traffic is negligible and maintaining compatibility hinders progress, plan a phased deprecation with redirects and user messaging.
  • Graceful fallback page: Offer a lightweight banner or page advising users to upgrade for full experience, while keeping essential content accessible.

Quick Actionable Checklist (Short)

  1. Add <!DOCTYPE html> and IE=edge meta tag.
  2. Server-render core content and meta tags.
  3. Transpile JS and include minimal polyfills.
  4. Provide CSS fallbacks and avoid nonstandard features.
  5. Ensure semantic HTML, alt text, and keyboard navigation.
  6. Verify robots.txt, sitemap, canonical tags are present.
  7. Serve structured data in-page (not JS-only).
  8. Optimize assets and enable caching.
  9. Test on target IE versions and monitor analytics.
  10. Plan deprecation if IE usage is insignificant.

If you want, I can convert this into a printable one-page checklist or generate a CI test script to check key compatibility points.
