feat(seo): modularize metadata pipeline and resolve Bing SEO scan issues by alienx5499 · Pull Request #839 · alienx5499/SortVision

alienx5499 · 2026-04-25T11:45:25Z

This Pull Request improves SEO infrastructure and resolves Bing Webmaster recommendations around duplicate/short metadata.

It changes the following:

Refactor large SEO code into modular components under src/components/seoContent (helmet scripts, hidden content blocks, shared FAQ data, constants).
Introduce centralized SEO/version constants in src/constants/version.js and wire them across the SEO stack.
Expand dynamic sitemap generation in src/app/[lang]/sitemap.xml/route.js to include canonical + legacy route families and multilingual variants.
Fix robots.txt routing conflict by relying on static public/robots.txt and removing conflicting app route.
Add and register structured data modules (WebSite, Breadcrumb, Person, Organization, Algorithm-specific FAQ, etc.) while preserving existing schemas.
Fix SEO metadata consistency issues:
- remove noarchive from robots/bot directives (Bing/Copilot grounding compatibility),
- make title tags unique across algorithm tabs and contribution sections,
- make meta descriptions unique and normalize them to a Bing-friendly length range.
Keep Lighthouse SEO score at 100 in production-mode local validation after the above changes.

Changes:

Modularized Helmet meta tags + JSON-LD schema scripts and hidden SEO content under src/components/seoContent/.
Centralized SEO/version/author constants in src/constants/version.js and wired them into schema/meta generation.
Replaced static sitemap serving with dynamic sitemap generation and removed the app-route robots.txt handler in favor of public/robots.txt.
