April 2026

2026-04-06 — Author Page, Tool Documentation & Structured Data Fix

• New page: Developer / Author — Added a dedicated page explaining who builds Polymorpher, the technical background, domain expertise, and content philosophy. Linked from all page headers and footers.
• Rich tool documentation: Every tool page now includes live input/output examples, edge-case descriptions, "when to use / when not to use" guidance, and reference tables (e.g., SQL type mapping, hash algorithm comparison, JWT claim reference).
• Fixed FAQ structured data: Resolved a "Duplicate field FAQPage" error reported by Google Search Console — merged two separate FAQPage blocks into a single valid schema.
• Fixed broken blog links: Corrected internal links in blog posts that pointed to non-existent HTML files.
• Content rendering fix: Server-injected SEO content is no longer overwritten by shorter client-side JavaScript on direct page visits, ensuring Google sees the full documentation.

2026-04-05 — SEO & Quality Improvements

• New page: Editorial Policy — Explains how content is created, reviewed, and corrected. Includes AI usage disclosure and commercial independence statement.
• New page: Changelog — This page. Public record of updates for transparency.
• Dynamic sitemap: lastmod dates now reflect actual file modification times instead of static "today" dates.
• Content consolidation: Five blog posts with overlapping topics were consolidated via noindex + canonical tags pointing to comprehensive guides, reducing duplicate content signals.
• JSON-LD URL fix: All 12 tool structured-data URLs corrected from /tools/{slug} to /{slug} to match live routes.
• Language consistency: Four Turkish UI messages translated to English for full language consistency.
