🏷️ Meta Tag Analyzer

Extracting structured data and meta tags from arbitrary websites is essential for technical SEO audits, site migrations, and competitor analysis. This automation tool crawls web pages to accurately extract schema.org JSON-LD, Open Graph tags, Twitter cards, viewport configurations, and crucial robots directives from hundreds of URLs in seconds. Built for SEO professionals, data engineers, and developers, this web scraper replaces manual element inspection by programmatically reading exactly how search engines and social media platforms view your website content.

Schedule weekly scraper runs to continuously monitor your site's health. Catch truncated page titles, missing canonical links, broken social preview images, or accidental noindex directives before they negatively impact your search results. Whether you need to scrape product details embedded via schema markup, validate organization data, or extract contact details from competitor websites, this tool delivers highly structured, perfectly formatted data.

The output details exactly what a browser sees when loading your pages. Concrete extracted fields include full HTML head metadata, canonical URLs, charset configurations, structured JSON-LD payloads, meta descriptions, and custom tags. Use these scraped results to feed dashboards, integrate with internal reporting tools, or conduct bulk technical validation across vast domain portfolios.

FAQ

Which meta tags are most important for SEO?

title, description, canonical, and robots are critical. og:image matters for social shares. hreflang matters if you have multilingual content.

Can it follow redirects?

Yes. Meta tags are extracted from the final URL after redirects.

Does it render JavaScript?

No. Tags are extracted from initial HTML only. If your site renders tags client-side, this actor won't see them.

What issues are flagged?

Truncated titles (>60 chars), missing description, missing canonical, missing og:image, duplicate meta description.

Does it render JavaScript?

No — it parses raw HTML. Tags injected by client-side JS won't be captured.

Can I extract structured data (JSON-LD)?

Basic Open Graph and Twitter Card metadata only. JSON-LD parsing is on the roadmap.
