The SEO Schema Validator crawls your target sitemap, extracts all JSON-LD schema markup, and validates it against Schema.org standards and Google's Rich Result requirements. ### Why use this Actor? * Bulk Validation: Don't check one URL at a time. Input a sitemap and validate 1,000+ pages in minutes. * Rich Result Eligibility: Instantly spot pages missing critical keys (e.g., missing aggregateRating in Product schema or datePublished in Article schema). * Syntax Error Detection: Identify broken JSON, unclosed brackets, or invalid types that break your SEO. * Agency-Ready Reporting: The output is structured as a clean JSON/CSV dataset, ready to be converted into client reports or dashboards. ### Key Features ✅ Validates deeply nested JSON-LD objects. ✅ Checks for presence of critical Meta Tags (Title, Description, Robots). ✅ Detects "silent" errors that don't break the page but do break the snippet. ✅ Returns a "Health Score" for every URL. ## Input | Field | Type | Description | Default | |---|---|---|---| | sitemap_url | String | The URL of the sitemap to crawl. | Required | | start_urls | Array | Fallback list of URLs if no sitemap is provided. | Optional | | smart_sampling | Boolean | Enable pattern-based sampling for large sites. | true | | max_pages | Integer | Maximum number of pages to check. | 1000 | ### 💡 How to Find a Website's Sitemap Most websites have a sitemap at one of these common locations: 1. The Standard Path: Check yourdomain.com/sitemap.xml. 2. Robots.txt: Visit yourdomain.com/robots.txt. Most sites list their sitemap URL(s) there. 3. Sitemap Index: Large sites often use an index, like yourdomain.com/sitemap_index.xml. 4. Common Platforms: * WordPress: Typically /sitemap.xml, /sitemap_index.xml, or /wp-sitemap.xml. * Shopify: Usually /sitemap.xml. * Squarespace: Usually /sitemap.xml. If you still can't find it, try searching Google for site:yourdomain.com filetype:xml sitemap. ### Input Example json { "sitemap_url": "https://apify.com/sitemap.xml", "smart_sampling": true, "max_pages": 1000 } ## Output The actor stores results in the default dataset. Each item represents a page and includes: json { "url": "https://example.com/product/123", "health_score": 85, "issues": [ { "severity": "CRITICAL", "message": "Product schema missing 'name'.", "context": "..." } ], "meta": { "title": "Product Name", "description": "Great product description.", "canonical": "https://example.com/product/123", "og_image": "https://example.com/img.jpg" }, "schemas_found": 1 } ## Health Score Calculation The actor computes a per-page health_score as an integer in the range 0–100. The calculation is designed to highlight critical structural issues first. Rules: - Start at 100 points. - For each CRITICAL issue subtract 20 points. - For each WARNING issue subtract 5 points. - INFO issues do not deduct points. - The score is clamped to a minimum of 0. Common CRITICAL issues (deduct 20 points): - Missing <title> tag. - Invalid JSON-LD syntax (broken code). - Schema missing @context or @type. - Missing required schema properties (e.g., Product without name). Common WARNING issues (deduct 5 points): - Missing meta description. - Schema @context value that does not reference schema.org. - Missing canonical link element. ## How to use the output The results are saved in the "Dataset" tab of your run. You can: 1. Export the data to CSV, JSON, or Excel. 2. Filter by health_score to find the worst-performing pages first. 3. Share the report with your team or clients to fix the issues. ## FAQ * Q: Does this actor submit data to Google or other services? * A: No. It only reads pages and writes validation reports to your dataset. * Q: Will the actor change or write to my site? * A: No. The actor performs read-only checks. * Q: Can I run this actor on a schedule? * A: Yes — use Apify platform scheduling features to run this audit regularly (e.g., weekly). ## Support & Feedback If you find bugs or want to request features, please open an issue in the project repository.
