On-Page SEO, OpenGraph, JSON-LD Schema & Metadata Auditor

A lightweight, high-performance technical SEO auditor that analyzes web pages without the heavy overhead of headless browsers. Extracts title & meta descriptions, canonical URLs, robots directives, social OpenGraph & Twitter Cards, Schema.org JSON-LD structured data, heading hierarchies (H1-H6), and missing image alt tags.

🚀 Why Use This Actor?

Traditional SEO crawlers launch full Chromium/Puppeteer instances, eating gigabytes of RAM and taking 10–20 seconds per page. This Actor runs in milliseconds using direct HTTP parsing:

• 10x Faster & Cheaper: Processes dozens of pages per second with negligible compute costs.
• OpenGraph & Twitter Cards: Validates social sharing previews (title, image, card type).
• Schema.org Microdata Extraction: Parses embedded JSON-LD scripts into clean, queryable JSON objects.
• Heading Structure Audit: Verifies clean H1-H6 hierarchy and flags missing or duplicate H1 tags.
• Image Accessibility Check: Counts images lacking alt tags to maintain WCAG accessibility standards.
• On-Page SEO Score: Computes an automatic 0–100 health score for instant agency reporting.
