Your site is invisible to AI search. This plugin fixes that — in one click. Google AI Overviews, ChatGPT Search, Bing Copilot, and Perplexity all depend on structured data to understand and surface your content. Without it, your pages are just text. With it, you become a trusted source that search engines and AI systems actively quote, reference, and rank. Voidek Auto Schema Generator automatically injects JSON-LD structured data across your entire site — articles, products, reviews, and every individual page type — without you writing a single line of code. Install. Activate. Done. Who Is This For? WooCommerce store owners who want price, stock, and ratings showing in Google search results Bloggers and publishers looking to appear in Google News, Discover, and AI-generated summaries SEO professionals and agencies who need fast, reliable structured data across multiple sites Site owners preparing for AI search — Google AI Overviews, ChatGPT, Perplexity, and Bing Copilot Developers who want clean, extensible schema output with WordPress filter hooks What Makes This Plugin Different Most schema plugins bolt on a few basic properties. Voidek goes deeper. Every page on your site gets the right schema type automatically. Your About page becomes an AboutPage. Your FAQ page becomes a FAQPage with questions and answers extracted from your content. Your Contact page gets a full ContactPoint. Your WooCommerce checkout gets an OrderAction. All without configuration. That is what makes your site truly machine-readable — not just your homepage or product pages, but every URL. The 4 Schema Types Included — 100% Free Article Schema Every blog post and article gets a complete schema block covering headline, description, author, publisher, publish date, modified date, and featured image. This is what gets your content into Google News, Google Discover, and AI-generated article summaries. WooCommerce Product Schema Product pages get rich schema covering name, images, description, dynamic price, live stock status, brand, SKU, and review ratings. This is what puts star ratings and price directly into Google Shopping and search results. Review and Rating Schema Star ratings (1–5), review count, and reviewer information are structured and output separately, building instant credibility in the SERP before users even visit your site. WebPage Schema — Smart Page-Type Detection This is where Voidek stands apart. Rather than applying one generic WebPage schema to everything, the plugin reads each page’s slug and automatically assigns the correct schema type: About, about-us, our-story → AboutPage (with full organization schema) Contact, contact-us, get-in-touch → ContactPage (with ContactPoint, email, phone, language) FAQ, faqs, help, questions → FAQPage (Q&A pairs extracted automatically from your content) Checkout, cart, basket → CheckoutPage (with OrderAction — WooCommerce required) Profile, author, bio → ProfilePage (with Person entity as mainEntity) Portfolio, gallery, blog, resources → CollectionPage Search, search-results → SearchResultsPage Health, medical, wellness → MedicalWebPage (with audience and reviewedBy) Privacy policy, terms, disclaimer, cookie policy, refund policy → WebPage with legal genre Any other page → WebPage (sensible default) Every page — regardless of type — also gets these automatically: Full BreadcrumbList with all ancestor pages and positions Organization schema for publisher, copyright holder, and maintainer (with logo) Author Person schema with bio, Gravatar, and social profiles Featured ImageObject with dimensions and primaryImageOfPage Word count, estimated reading time, and keywords (merged from tags, Yoast focus kw, Rank Math focus kw) About entities, Wikipedia-linked mentions, significant internal links Section map (hasPart) — one WebPageElement per H2 heading with text preview Accessibility properties (accessMode, accessibilityFeature, accessibilityHazard) Post slug and post ID as structured identifiers Comment count as InteractionCounter (when comments exist) ReadAction for all public, non-password-protected pages Works With Your Existing SEO Setup Voidek reads and respects data from the tools you already use: Yoast SEO — meta description, focus keyword, social profiles Rank Math — meta description, focus keyword, social profiles All in One SEO The SEO Framework WooCommerce Any other SEO plugin — no conflicts Built for the New Era of Search Structured data is no longer optional.
