faq
What structured data formats are supported?
JSON-LD, Microdata, and RDFa. The scraper also extracts Open Graph, Twitter Cards, and Dublin Core metadata.
How is the SEO score calculated?
The 0-100 score evaluates title tags, meta descriptions, heading hierarchy, image alt text, canonical URLs, mobile viewport, structured data presence, and more.
Can I audit multiple pages at once?
Yes, provide multiple URLs in startUrls. The scraper processes them in parallel for fast bulk auditing.
