Schema Engine AI – AI Schema Markup, Reviews & Rich Snippets for SEO vs Schema Star

Schema Engine AI is an AI-powered schema markup plugin for WordPress that generates valid JSON-LD based structured data, generate FAQ content from your existing pages, validates output against Google Rich Results requirements, and produces a site-wide schema audit. It is designed for editors and site owners who want clean, accurate structured data without writing JSON-LD by hand, and for SEO professionals who need a validator and a report alongside their existing workflow. 📢 Important: Review Schema is now Schema Engine AI Same plugin, same review and rating features, plus AI-powered schema generation for articles, FAQs, products, and more. Your existing reviews and settings are preserved automatically. 👉 Demo | Documentation | Support | Get Pro 👈 The plugin supports three ways to work: Manual Mode: Build or edit JSON-LD for any schema type with complete control over properties and nesting. Ideal for technical SEOs. Auto Mode: Applies rule-based schema generation across post types, adapting to your content type and site structure without manual configuration. AI Mode: Proposes a schema type and pre-fills properties from your content. Every output is checked against Schema.org and the public Google Rich Results documentation, and editors review the result before it is saved. Why Schema Engine AI (Formerly Review Schema) Most schema plugins ask you to fill in long forms or apply one-size-fits-all templates. Schema Engine AI lets you choose the level of automation that fits the page in front of you. A blog post can use Auto mode and a template. A complex landing page can use AI mode to draft a starting point, which you then edit. A product or local business page can use Manual mode for full control. The validator runs in the background in all three modes, so you see what is missing before you publish, not after. AI as a drafting tool, not an autonomous publisher. Suggestions are reviewed and edited by a human before they are saved. Rich results validator built in. Required and recommended properties are flagged in real time, so you see what is missing before you publish. Site-wide audit. One screen shows which content has valid markup, which has warnings, and which has none. Graph relation output. A connected @graph links Organization, WebSite, WebPage, Author, and content schemas so search engines understand entity relationships. SERP Preview. See how your structured data will appear as a Google search result card directly in the post editor. Editor-friendly.

It detects the content type article, event, local business, FAQ, and more then pre-fills every required and recommended property.

It is not a direct ranking factor, but it is a prerequisite for many features that improve visibility and click-through rate. SEO. Pages with valid schema are eligible for Google Rich Results: review stars, FAQ dropdowns, product cards, recipe cards, breadcrumbs, and similar features. These features tend to increase click-through rate from organic search. AEO (Answer Engine Optimization). Featured snippets, voice assistant answers, and direct answer boxes select content that is structured, specific, and easy to extract. FAQPage and HowTo schema map directly to these surfaces. GEO (Generative Engine Optimization). AI search experiences such as Google AI Overviews and answer engines synthesize answers from sources they trust. Clear structured data helps these systems understand what your page is about and which claim came from where. Data Migration Migrate your existing structured data from the WP SEO Structured Data Schema plugin without losing a single entry. Schema Engine AI maps each schema type to its Schema Engine AI equivalent, and transfers all properties — including nested objects and custom fields — into the new format. External services and data handling AI Schema Generator and AI FAQ Generation send the post content you choose to process to a third-party large language model provider. The provider is the one whose API key you enter in plugin settings (OpenAI, Anthropic, or Google). No content is sent to any AI provider until you connect a key and trigger a generation. The plugin does not transmit content to RadiusTheme servers. OpenAI API. Terms of Use | Privacy Policy Anthropic (Claude) API. Terms of Service | Privacy Policy Google (Gemini) API. Terms of Service | Privacy Policy Manual and Auto modes do not contact any external service. How AI is used in this plugin In line with Google’s public guidance on AI-generated content, AI in Schema Engine AI is a drafting tool. The model suggests a schema type and property values; an editor reviews and edits the output; the rich results validator checks the result against Google requirements before it is written to the page.

Schema Star is a comprehensive WordPress plugin that adds Schema.org structured data markup to your website, helping you achieve rich snippets, enhanced search appearances, and dramatically improved SEO performance in Google and other search engines. Every feature is designed to make your site not only rank better but also look better and more trustworthy in search results—with star ratings, breadcrumbs, FAQ expandables, sitelinks search box, organization and local business knowledge, and more. This is the demo/free version. Some advanced features (e.g. Product Reviews management page, Product Group settings page) are available in the Pro version. For step-by-step configuration and usage from a fresh install, see Configuration Steps and How to configure and use below. Organization Settings & Organization Markup Schema Star lets you add Organization Schema to your main or home page. You configure your company name, URL, logo URL, contact details, social profiles, and optional business hours. This structured data tells search engines exactly who you are as a business. How it improves search appearance: Google can use this to build or enrich a Knowledge Panel for your brand, show your logo next to your listing in search results, display sitelinks under your main result, and associate your content with a verified entity. A clear Organization markup strengthens E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) and helps your brand stand out in competitive search results. WooCommerce Settings (Product, Category, and More) The plugin provides a dedicated WooCommerce Settings area with tabbed sections: Product tab — Control product schema globally: enable/disable product markup, release date, awards, seller name, sale dates, description word limit and source for schema. This ensures every product page outputs rich Product schema so Google can show price, availability, ratings, and brand directly in search results, increasing click-through rates and purchase intent. Category tab — Configure Category Schema (CollectionPage / ItemList) for your product categories: enable category schema, set maximum products per category in the schema, and manage Shipping & Currency (country of origin, base currency, exchange rates, currency-to-country mapping), Payment & Return Policy (payment methods, return policy text, return countries, return category, fees, method, return days, multilingual return policy), General Product Settings (tracking, return days, product condition, warranty, shipping time), and Canonical Settings (canonical URLs, rel=prev/next). Category and product schema together make your store appear as a structured, trustworthy e-commerce site in search, with correct pricing and policies visible to users before they click. Local Business Settings Local Business Schema is configured separately (Schema Star → Local Business Markup). You choose from 30+ business types (Store, Restaurant, Hotel, Medical, Legal, Dentist, Fitness Club, Real Estate Agent, Travel Agency, etc.), add your Business Image URL (with media upload), price range, contact information (phone), location (street, city, region, postal code, country code), geographic coordinates (latitude/longitude), and business hours (weekdays and weekends). How it improves search appearance: Google uses this data for Local Pack and Google Maps listings, shows your address and opening hours in the snippet, and can display a map pin or \”Open now\” / \”Closes at\” in search results. Local Business markup is essential for \”near me\” searches and local SEO, making your business visible and actionable directly from the search page. FAQ Schema Settings FAQ Schema allows you to add question-and-answer structured data to posts, pages, and optionally to taxonomies (e.g. categories). You enable FAQ for the post types you want, then add questions and answers via the FAQ metabox when editing content. How it improves search appearance: Google can show your FAQ as expandable rich results (accordion-style) directly in the search results. This increases your real estate on the SERP, answers user queries without a click, and often improves click-through rate because the result looks more informative and authoritative. FAQ snippets are especially valuable for how-to, support, and product-related content. Custom Schemas The Custom Schema Builder lets you create and attach 20+ schema types to specific pages or posts: Article, Book, Course, Event, JobPosting, Recipe, VideoObject, HowTo, Person, Service, SoftwareApplication, Review, Vehicle, Podcast, Movie, and more. You select the schema type, choose target content, and fill in fields (with optional auto-fill from WordPress data). How it improves search appearance: Each schema type unlocks specific rich results—e.g. Recipe can show cooking time and rating, Event can show date and venue, JobPosting can show salary and location in job search. Custom schemas let you tailor structured data to your content and maximize the chance of rich snippets and enhanced listings for every page type. Posts Schema Settings Posts Schema Settings control how blog posts (or other post types) are represented in structured data—for example whether to include the featured image in the schema. This ensures your article or blog post schema is complete and eligible for Article or NewsArticle rich results, which can show images and publish dates in search and in Discover, improving visibility and clicks. LMS Integration (Course Schema) Schema Star adds Course and ItemList schema for popular Learning Management Systems: Tutor LMS, LearnDash, LearnPress, and Masteriyo. On single course pages you get full Course schema (name, description, provider, price, etc.); on course category and archive pages you get ItemList schema listing courses. How it improves search appearance: Course-rich results can show course title, provider, and price in search and in Google’s education/search features, helping your courses stand out and attract students directly from search results. SiteNavigationElement When you enable SiteNavigationElement schema, the plugin outputs structured data for your site’s main navigation based on a selected menu. You choose which WordPress menu represents your primary navigation. How it improves search appearance: Search engines understand your site structure better; this can support sitelinks (additional links under your main result) and help Google show the most important sections of your site in search. It reinforces site hierarchy and improves crawlability and relevance signals. About Page & Contact Page Schema Star lets you select an About page and a Contact page from dropdowns. These choices link the appropriate schema (e.g. Organization, LocalBusiness) to the correct URLs. How it improves search appearance: Search engines can associate your \”About\” and \”Contact\” content with your entity, show the right links in Knowledge Panel or sitelinks, and give users a clear path to learn about you or get in touch—all from the search result. Product Reviews (Review Snippet) Product Reviews Schema uses your WooCommerce product reviews to output Review and AggregateRating structured data. How it improves search appearance: Google can display star ratings (e.g. ★★★★☆ 4.5 · 120 reviews) next to your product listing in search results. Star ratings dramatically increase visibility and click-through rates because they signal quality and social proof directly in the SERP. Auto ALT Tags (Product Images ALT) The Auto ALT Tags feature automatically adds or improves ALT text for product images. How it improves search appearance: ALT text is used for image SEO (Google Images) and accessibility. Better ALT text helps your product images rank in image search and gives search engines a clearer understanding of your product, which can indirectly support product rich results and overall relevance. BreadcrumbList When BreadcrumbList schema is enabled, the plugin adds breadcrumb structured data to your pages (excluding cart, checkout, and similar pages). How it improves search appearance: Google can show breadcrumb navigation in the search snippet (e.g. Home > Category > Product). Breadcrumbs make your listing look more organized, help users understand where they are on your site, and can improve click-through rate by clarifying context. Enable Search Schema (SearchAction) SearchAction schema tells Google that your site has a search function and how to trigger it (e.g. URL pattern). How it improves search appearance: Google may show a sitelinks search box under your result in search results, allowing users to search your site without leaving the SERP. This increases brand exposure and drives qualified traffic. Force HTTPS Redirect The Force HTTPS Redirect option adds a rule (e.g. in .htaccess) to redirect all HTTP traffic to HTTPS. How it improves search appearance: HTTPS is a ranking signal for Google and is required for many modern browser features. A secure site is favored in search and builds user trust; mixed content or non-HTTPS can hurt rankings and rich result eligibility. Additional Capabilities Multi-Currency Support — Set base currency, exchange rates, and currency-to-country mapping so product schema shows correct prices per region in search. Shipping & Return Policy — Shipping details, return policy, return days, fees, and method in schema build trust and can be reflected in merchant listings and rich results. Canonical & rel=prev/next — Proper canonical URLs and pagination tags keep indexation clean and help search engines show the right version of your pages. Translation-Ready — Full i18n support so you can run the plugin in any language and still output valid, locale-appropriate schema. Together, these features make Schema Star a complete solution for Organization, Local Business, WooCommerce (Product & Category), FAQ, Custom Schemas, Posts, LMS Course, Breadcrumbs, Search, Navigation, Contact/About, Reviews, ALT tags, and HTTPS—giving your WordPress store or site the best possible appearance and performance in search engines.
