The fastest bulk SEO meta tags and headings extractor — audit titles, meta descriptions, headings, canonicals, social cards, and schema across hundreds of URLs in one pass.

What you get

Paste a list of URLs and get a complete on-page SEO snapshot for each one: title, meta description, heading hierarchy, canonical, robots directive, Open Graph and Twitter social cards, schema markup, image alt-text gaps, internal/external link counts, and word count. Designed for SEO consultants, content auditors, and in-house SEO teams who need real on-page data across hundreds of pages without firing up a desktop crawler.

Output fields

Field	Description
url	The URL you submitted.
final_url	The URL after following redirects.
status_code	HTTP status code (200, 301, 404, etc.).
title	The <title> tag text.
title_length	Character count of the title (Google typically truncates over ~60).
meta_description	The meta description tag.
meta_description_length	Character count (Google typically truncates over ~160).
meta_keywords	The meta keywords tag (rarely used today).
canonical	The canonical URL declared by the page.
robots_meta	The meta robots directive (e.g. index,follow, noindex).
viewport	The viewport meta tag (mobile-friendliness signal).
lang	The lang attribute on the <html> tag.
charset	Character set declared by the page.
h1_tags	List of unique H1 headings on the page.
h2_tags	List of unique H2 headings on the page.
h1_count	Total H1 tags (more than one is an SEO smell).
h2_count	Total H2 tags.
h3_count	Total H3 tags.
h4_count	Total H4 tags.
og	Open Graph tags (og:title, og:description, og:image, etc.) as a flat dict.

json_ld	Parsed schema markup blocks (Product, Article, FAQ, Breadcrumb, etc.).
images_total	Total <img> tags on the page.

external_links	Links pointing to other domains.
nofollow_links	Links marked rel="nofollow".
word_count	Visible word count (script and style content excluded).
text_to_html_ratio	Word count divided by HTML byte size — low values flag thin or template-heavy pages.

Input parameters

Parameter	Required	Description
urls	Yes	List of page URLs to audit. Each URL produces one result.
timeoutSecs	No (default 20)	Maximum seconds to wait for each page (1–120). Slow pages report a timeout error.
concurrency	No (default 10)	How many pages to fetch in parallel (1–50).
userAgent	No	The User-Agent header sent with each request. Override to mimic a specific bot or browser.
proxyConfiguration	No	Optional Apify proxy. Most public pages don't need one.

Use cases

• SEO consultants running on-page audits — surface every page missing a title, meta description, or canonical, and rank H1 issues across the whole site.
• Content auditors cleaning up legacy content — find thin pages by word count and text-to-HTML ratio, then prioritize rewrites.
• In-house SEO teams monitoring schema coverage — verify every product page has Product schema, every article has Article schema, and every FAQ page has FAQ schema.
• Accessibility leads finding images missing alt text — get a per-page count and prioritize the worst offenders.
• Competitive researchers comparing social previews — pull Open Graph and Twitter cards from a competitor's blog to see how they package shares.

Limitations

• Captures the HTML the server returns. Pages that render their content entirely in the browser (heavy single-page apps) may show empty title, missing headings, or zero links — for those sites, use a browser-based scraper instead.
• Some sites rate-limit aggressive scraping. Use the proxy option if you start hitting 403s.
• Word count is computed from visible text after removing script and style content. Inline SVG and obscure HTML may slightly inflate or reduce the count.
• Schema markup blocks that are syntactically broken are skipped rather than failing the whole audit.
• Authenticated pages are not supported — this is for public URLs only.

FAQ

Does this respect robots.txt? This actor sends one request per URL and does not crawl. It uses a clearly identifiable User-Agent (ThirdwatchSEO/1.0) so site owners can recognize and rate-limit it if they want.

What's the rate limit? You control it via concurrency (max 50). For sites you don't own, keep it low and enable the proxy option if you hit 429 or 403.

Can I audit pages behind a login? No — this actor does not handle authentication, cookies, or session headers. It's designed for public URLs.

Why are some fields empty on JavaScript-heavy sites? Single-page apps render content in the browser after the initial HTML loads. This actor reads the server-rendered HTML only. For React/Vue/Angular sites with no server-side rendering, use a browser-based audit tool instead.

Does it capture every kind of schema markup? It returns every structured-data block the page declares in script tags (Product, Article, FAQ, Breadcrumb, and others) as structured data. Microdata and RDFa formats are not captured.

SEO meta tags and headings extractor for site-wide audits

Run a full on-page SEO audit across an entire site in minutes. Pair it with the Subdomain Finder to map a domain's full footprint before auditing, or with Google Search Results Scraper to check how audited pages are actually ranking.
