Bulk Structured Data Validator Across Pages

WHAT IT DOES

Bulk Structured Data Validator Across Pages is a developer and SEO tool that streamlines the process of validating structured data across multiple URLs. Instead of manually visiting each page, inspecting the source code for JSON-LD, Microdata, or RDFa, and recording schema types—a process that can be tedious and time-consuming—this script automates the entire workflow. It scans the current page for URLs and links, displays them as a scrollable checklist with titles and hostnames, and performs GET requests to fetch and validate structured data for each selected URL. The script extracts schema types (e.g., Product, Article, Organization, FAQPage) and key properties from JSON-LD blocks, counts the number of structured data entries, and indicates the status (✅ Found, ❌ None, ⏱ Timeout, ❌ Error). Results can be exported as plain text, CSV, or TSV via clipboard. This is ideal for SEO specialists, web developers, content managers, and anyone who needs to audit structured data implementations across websites.

WHERE IT RUNS

This script is universal—it runs on any website (*://*/*) as a userscript injected through the BotGentz extension. It operates within the context of your current browser tab and cannot access other tabs, bookmarks, history, or downloads. The script reads the page DOM to identify URLs using links and text patterns, extracts titles and hostnames, and performs GET requests to fetch HTML content and parse JSON-LD structured data. All operations occur locally in your browser; no data is sent to external servers except for the page requests themselves.

HOW TO USE

1. Navigate to any page containing a list of URLs you want to check—a site directory, a client portfolio, a links page, or any text with URLs.

2. Click the BotGentz extension icon and select "Bulk Structured Data Validator Across Pages" from the script list.

3. The panel opens on the right side of the page. It automatically scans the current page for URLs.

4. Review the detected URLs, showing titles and hostnames with pending status (⏳).

5. Configure "Timeout (ms)" (default 10000) and "Max concurrent" (default 3) to control the validation process.

6. Select your export format: Plain Text, CSV, or TSV.

7. Toggle "Validate with schema" to enable schema validation (if supported).

8. Check the boxes next to URLs you wish to validate. Use "Select All" or "Deselect All" for quick selection.

9. Click "Validate Structured Data" to begin. The script fetches each page and extracts JSON-LD structured data.

10. Results appear in the panel with status indicators showing the number of schema types found.

11. Click "Export Results" to copy the validation results to your clipboard in the selected format.

WHY IT WORKS WHERE OTHERS FAIL

Many SEO audit tools require crawling entire websites or paying for API access. This script takes a different approach: it works with URL lists you already have and performs on-demand validation using simple GET requests and HTML parsing. It extracts JSON-LD structured data using regex patterns that handle variations in script tag formatting and content, and recursively traverses the JSON objects to extract schema types and properties. The script supports multiple schema types per page and provides a summary of all types found. By supporting configurable concurrency and timeout settings, it efficiently handles large URL lists without overloading your browser or the target servers. The detailed status indicators provide immediate visual feedback, and the export functionality makes it easy to share audit results with your team or integrate into other workflows.

THE PANEL

The script uses BotGentz's BGPanel system, which provides a floating, draggable panel on the right side of your screen. Drag the panel by its header to reposition it anywhere on the page—the panel remembers its position per site and snaps to the nearest edge when released. Click the minimize button to collapse the panel to a small floating bubble; click the bubble to expand it back. Resize the panel vertically by dragging its bottom edge. Press the Escape key to close the panel entirely. All panel state (position, collapsed/expanded) is persisted locally using GM_setValue, so your preferences survive page reloads.

PLEASE NOTE

This userscript requires the free BotGentz browser extension—it is not a standalone application. The script fetches the HTML content of each selected URL to validate structured data; this may be slow for large numbers of URLs and depends on the target server's response time. Some websites may block automated requests or return non-HTML content. The script extracts JSON-LD structured data but does not perform full schema.org validation. This script does not store, transmit, or process any of your data outside your local browser except for the page requests. It does not access your password, hidden inputs, or file inputs. Use responsibly and respect website robots.txt and terms of service.
