How do I test which Google rich result my JSON-LD is eligible for — with a preview — without uploading my markup?
Open AnyTool’s Rich Snippet Tester and paste your JSON-LD (a raw object/array, a <script type="application/ld+json"> block, or your page HTML). For every object it resolves the schema.org @type, maps it to the Google rich result it can produce (Review stars, Product price snippet, FAQ, Breadcrumb, Recipe, Event, Article, Video, Job posting and more), checks Google’s documented required properties, and gives a clear verdict — eligible, missing required fields (it lists exactly which), or no rich-result type — plus recommended fields to add. It then renders a VISUAL MOCK PREVIEW built from your markup: a star rating with review count, a Product card with price and availability, an expandable FAQ accordion, a Breadcrumb trail, a Recipe card with rating and time, an Event date row, an Article snippet. Everything runs in your browser, so your markup is never uploaded — safe for staging. Being eligible is not a guarantee the rich result shows (Google decides by quality, trust and relevance, and FAQ/HowTo are restricted or removed), so confirm in Google’s Rich Results Test.

What is
Rich result eligibility (rich snippet testing)
Rich result eligibility is whether a page’s structured data meets Google’s documented requirements for a specific rich result — the enhanced Search appearance such as review stars, a product price, an FAQ accordion, a breadcrumb trail or a recipe card. A piece of markup is eligible when it declares the right schema.org @type and includes all of that rich result’s required properties; missing a required property makes it ineligible. Eligibility is necessary but not sufficient: Google still decides whether to show the rich result per query based on content quality, trust and relevance, and some result types (like FAQ and HowTo) have been restricted or removed.
This one focuses on rich-result eligibility and a visual SERP preview. The Schema Validator does deep per-property validity of one snippet; the Structured Data Tester inventories every format on a whole page.
They are three siblings for three jobs that share the same engine. The Rich Snippet Tester answers “which Google rich result is this eligible for, what required fields are missing, and how could the snippet look?” — it maps each object to its rich result, lists missing required and recommended fields, and renders a visual mock preview (stars, price, FAQ, breadcrumb, recipe, event, article). The Schema Validator is snippet-level and validity-focused: it checks @context, @type and every required/recommended property of one pasted JSON-LD block against a curated schema.org knowledge base. The Structured Data Tester is page-level: paste your whole page HTML and it inventories every JSON-LD block plus Microdata and RDFa. Use this tester to see eligibility and a preview, the Validator to perfect one block, and the page tester to audit an entire page.
No. Eligible means the required fields are present — but Google decides per query by content quality, trust and relevance, and some result types are restricted or removed.
Eligibility is necessary but not a guarantee. When the tester says “eligible”, your markup has all the properties Google documents as required for that rich result — but whether the rich result actually appears depends on Google’s per-query judgement of content quality, site trust and relevance, and on the markup matching what users see on the page. Some result types have changed: FAQ rich results stopped showing for all sites in 2026 (the markup stays valid and still helps AI search), and HowTo rich results were removed in 2023. Always confirm in Google’s Rich Results Test and watch Search Console for the rich-result reports.
Review/rating stars, Product price snippet, FAQ accordion, Breadcrumb trail, Recipe card, Event row, Article snippet, plus Video, Job posting, Local Business and Organization mocks.
For each detected type it renders a tailored mock of how the snippet could look in Search: AggregateRating / Review shows a star rating with the rating value and review count; Product shows a result with price, availability and stars; FAQPage shows an expandable Question/Answer accordion (with the note that FAQ rich results are now restricted); BreadcrumbList shows the navigation trail; Recipe shows an image placeholder with rating and total time; Event shows a date tile with the venue; Article shows a headline with date and source; Video, JobPosting, LocalBusiness and Organization get their own mocks, and anything else gets a generic result card. Every preview is built only from the fields in your markup.
No. The JSON-LD you paste is parsed and previewed entirely in your browser — nothing is uploaded, logged or stored, so it’s safe for staging markup.
The Rich Snippet Tester is 100% client-side. The JSON-LD or HTML you paste is parsed with plain JavaScript and the preview is rendered locally; nothing is fetched, uploaded, logged or stored on a server, and no page is crawled. Unlike online rich-result testers that send your data to a server, this is safe for staging, unreleased or internal markup you don’t want to expose before launch. It works offline once cached, and closing the tab discards everything you entered.
Detailed Explanation
📖How It Works
What the Rich Snippet Tester Checks and Previews
The Rich Snippet Tester answers a different question from its two siblings: not “is this markup valid?” (Schema Validator) or “what structured data is on this page?” (Structured Data Tester), but “which GOOGLE RICH RESULT is each object eligible for, what required fields are missing, and how could the snippet LOOK in Search?”. The user pastes JSON-LD — a raw object/array, a <script type="application/ld+json"> block, or a whole page’s HTML — and the shared engine schemaValidateEngine.ts extracts every object (expanding @graph and arrays). For each object the tool reads its schema.org @type and, via the engine’s RICH_RESULT_REQUIREMENTS map, identifies the rich result it can produce (review stars, Product price snippet, FAQ, Breadcrumb, Recipe, Event, Article / Top Stories, Video, Job posting, Local Business, Organization / sitelinks search box and more) and the properties Google documents as required. It then returns a per-object ELIGIBILITY verdict — eligible, missing required fields (with the exact list), or not a rich-result type — alongside missing recommended fields, and renders a VISUAL MOCK PREVIEW of how the snippet could appear, built entirely from the user’s own markup.
Focus: rich-result ELIGIBILITY + a visual SERP preview, distinct from the validity / inventory siblings
Reuses schemaValidateEngine.ts (extractJsonLd, RICH_RESULT_REQUIREMENTS, SCHEMA_KB) — engine NOT modified
Per-object verdict: eligible / missing required fields (exact list) / no rich-result type
All parsing and rendering is pure client-side JavaScript — no server call, no CDN, no upload
⚙️Methodology
How Eligibility Is Determined and Previews Are Built
For each extracted object the tester resolves the first @type and looks it up in the shared RICH_RESULT_REQUIREMENTS map, which records the Google rich result a type can produce and the properties Google documents as required for it. A property is treated as present only when it is a non-empty value (null, empty strings, empty arrays and empty objects count as missing). If the type has no rich-result entry, the verdict is “no Google rich result” (valid schema.org, no rich snippet). If it does, the tool computes which required properties are absent: none missing → ELIGIBLE; one or more missing → MISSING REQUIRED, with the exact field names listed so the user knows what to add. It also lists missing RECOMMENDED properties (from the engine’s SCHEMA_KB) that would make a richer result. The visual preview is rendered from the markup with small, dependency-free readers: a rating reader pulls ratingValue / reviewCount from aggregateRating, review.reviewRating or a bare Review/Rating node and draws a partial-fill star row; a Product preview reads offers.price, priceCurrency and availability; an FAQ preview turns mainEntity Questions into an expandable accordion; a Breadcrumb preview joins the ListItem names into a trail; a Recipe preview shows an image placeholder with rating and an ISO-8601 totalTime formatted to “20 min”; Event, Article, Video, Job posting, Local Business and Organization each get a tailored mock, and unknown types get a generic result card.
Type → rich result + required props comes from the shared RICH_RESULT_REQUIREMENTS map
Required present = non-empty (null/""/[]/{} count as missing); verdict computed from that
Recommended-missing list comes from the engine’s SCHEMA_KB for richer results
Star rows use partial fill scaled to bestRating; durations parsed from ISO 8601 (PT20M → 20 min)
Previews are built only from the user’s fields — no network, no external assets
⚠️Limitations
Eligible Is Not a Guarantee, and the Preview Is an Approximation
The tool is explicit about three honest limits. First, ELIGIBLE IS NOT A GUARANTEE: having every required property present makes a page eligible, but Google decides whether to actually show a rich result per query based on content quality, site trust and relevance, and the markup must match the visible page — a clean verdict here is necessary, not sufficient. Second, SOME RESULT TYPES ARE RESTRICTED OR REMOVED: FAQ rich results stopped showing for all sites in 2026 (after being limited to government and health sites since 2023), and HowTo rich results were removed in 2023; the markup remains valid and still helps AI and other engines, so the tool flags these caveats rather than hiding the type. Third, THE PREVIEW IS AN APPROXIMATION: it is a mock built from the user’s fields to illustrate how the snippet could look, not Google’s actual rendering, which varies by device, query and Google’s evolving SERP design. The tester therefore always advises confirming in Google’s official Rich Results Test and watching Search Console. For deep per-property VALIDITY of a single snippet the sibling Schema Validator is the right tool, and for a whole-page INVENTORY of every structured-data format the sibling Structured Data Tester is.

🔒Privacy & Security
Why Previewing Rich Snippets In-Browser Is a Privacy Win
Online rich-result testers send your markup — or a URL they crawl server-side — to a remote service. The Rich Snippet Tester instead runs entirely on the user’s device: the pasted JSON-LD (or HTML) is parsed with plain JavaScript, eligibility is computed from the shared engine, and the visual preview is rendered locally; nothing is fetched, uploaded, logged or stored, and no page is crawled. That makes it safe to test STAGING, UNRELEASED or INTERNAL markup before it goes live — a real advantage when you are iterating on structured data for a page that is not yet public and do not want to expose it to a third-party tester. It works offline once cached as a PWA, supports dark mode and mobile with a sticky test / copy bar, has exactly three ad slots, and adds NO new dependency: the type → rich-result mapping and required-property lists come from the small, reusable engine schemaValidateEngine.ts that the sibling Schema Validator and Structured Data Tester also share, while the per-type preview logic lives in the page itself.

AnyTool tests rich-result eligibility and previews the snippet locally from pasted JSON-LD and uploads nothing, which is safe for staging markup. Being eligible is not a guarantee the rich result shows (Google decides by quality, trust and relevance; FAQ rich results stopped showing for all sites in 2026 and HowTo rich results were removed in 2023), and the preview is an approximation — it is not the official Google Rich Results Test, so confirm there. Comparison as of June 2026.
