HeyTC SEO v1.0.0

First public release of HeyTC SEO — a lean, no-bloat structured-data SEO plugin for WordPress. ~3,000 lines, modern PHP 8.2+, zero shipped runtime dependencies.

Highlights

• Structured data (JSON-LD): Article / NewsArticle, Organization, WebSite, BreadcrumbList, FAQPage, with E-E-A-T author signals.
• Entity Links — map entity names to authoritative URLs, emitted as Article about / mentions.
• Google News sitemap, IndexNow ping-on-publish, canonical / meta / Open Graph / Twitter tags, per-post noindex / nofollow.
• Security hardening and Core Web Vitals helpers.
• Coexists with Yoast / Rank Math / AIOSEO / SEOPress / The SEO Framework — auto-detects them and stands aside to avoid duplicate output.
• Developer-first: everything site-specific is a WordPress filter (see the README hooks table).

Requirements

• WordPress 6.6+ (tested up to 7.0)
• PHP 8.2+

Engineering

GPL-2.0-or-later. CI across PHP 8.2/8.3/8.4 × WP 6.6/7.0, a blocking security scan, PHPStan, branch protection, and SHA-pinned Actions.
