SEO Site Audit & Broken Link Checker

What does SEO Site Audit & Broken Link Checker do?

This Actor crawls a whole website and audits every page for on-page SEO issues. Enter your homepage, and it follows all internal links and returns one row per page with the problems it found, plus a site-wide summary with broken pages and duplicate titles.

It checks what tools like Seobility, Screaming Frog or Ahrefs Site Audit check on-page, at a fraction of the price and without proxies or a browser, so runs are fast and cheap.

Why use this SEO audit tool?

• Find broken pages (404, 500) and the page that links to them
• Fix titles and meta descriptions that are missing, too short, too long or duplicated
• Check heading structure: missing or multiple H1, skipped levels (h2 → h4)
• Catch indexing problems: noindex, missing or foreign canonical tags
• Accessibility and sharing basics: images without alt text, missing lang, viewport and og:image
• Spot thin content and pages without structured data (JSON-LD)
• Agencies: audit client sites on a schedule and export to Google Sheets or Excel
• Pay per page: you control the cost with Max pages

What does the SEO audit check?

Issue code	Meaning
TITLE_MISSING, TITLE_TOO_SHORT, TITLE_TOO_LONG	Title missing, under 30 or over 60 characters
DESCRIPTION_MISSING, DESCRIPTION_TOO_SHORT, DESCRIPTION_TOO_LONG	Meta description missing, under 70 or over 160 characters
H1_MISSING, H1_MULTIPLE	No H1 or more than one H1
HEADING_LEVEL_SKIPPED	Heading levels skipped, e.g. h2 → h4
CANONICAL_MISSING, CANONICAL_POINTS_ELSEWHERE	No canonical tag, or it points to another URL
NOINDEX	Page is excluded from search engines
LANG_MISSING, VIEWPORT_MISSING	No lang attribute, no mobile viewport
OG_IMAGE_MISSING	No preview image for social media and messengers
STRUCTURED_DATA_MISSING	No JSON-LD structured data
IMAGE_ALT_MISSING	Images without alt attribute (alt="" counts as decorative and is fine)
THIN_CONTENT	Fewer than 300 words of visible text
HTTP_404, HTTP_500, …	Broken page
UNREACHABLE	Page could not be loaded at all (DNS error, timeout)

Each row also contains the raw values: title, description, lengths, H1, canonical, word count, image and link counts, and the page where the link was found (foundOn).

How much does an SEO site audit cost?

FAQ

Does it check external links?

Not yet. It checks every internal page of the website. External links are counted per page but not requested.

Does it work with JavaScript-heavy sites?

The Actor reads the HTML the server delivers, like most search engine crawlers do on the first pass. Sites that render all content only in the browser (some single-page apps) will show missing titles or thin content. That is often a real SEO problem in itself.

Will it overload my server?

No. It follows robots.txt by default and uses at most 10 parallel requests.
