Bulk On-Page SEO Audit: Score & Issues per URL

Audit any list of URLs for on-page SEO in one run. Each page gets a score, a grade and a list of issues: title, meta description, H1, canonical, noindex, image alt text, structured data, mobile viewport, HTTPS, redirects and more. The rules are fixed and published below, so every score is explainable and repeatable.

What is the Bulk On-Page SEO Audit?

Most SEO audit tools charge monthly for a crawler you may not need. This Actor does the on-page part for exactly the URLs you give it and charges per URL. It fetches each page like a browser, measures it, applies the rules below, and returns one row per page that you can sort and filter in a spreadsheet or feed into a dashboard.

What makes it different?

• Transparent scoring. Every issue lists its code, severity and points, and the score is 100 minus those points. No mystery number.
• Every row has the measurements, not only the verdict: title length, description length, H1 count, word count, images without alt, links, structured data types and more.
• Redirects and failures handled. The final URL, redirect count and response time are recorded, and pages that fail to load get a clear reason instead of a blank row.
• Safe by design. The Actor refuses to fetch private or internal addresses.

What data does the audit return?

Field	Example
url, finalUrl, status, redirects	https://example.com, the final URL, 200, 1
score, grade, errors, warnings	72, C, 0, 5
issues	[{ code: 'H1_MULTIPLE', severity: 'warning', points: 3, message: '5 <h1> headings…' }]
title, titleLength, metaDescription, canonical	the page's own values
h1Count, wordCount, images, imagesMissingAlt	5, 612, 14, 3
internalLinks, externalLinks, nofollowLinks	link counts
structuredDataTypes, openGraph, hreflang	JSON-LD types, which OG tags exist, language alternates

A SUMMARY record shows how many URLs were audited, the grade distribution and how many could not be fetched.

The scoring rules

Rule	Severity	Points off	What it checks
TITLE_MISSING	error	15	No <title>
TITLE_TOO_LONG	warning	3	Title over 60 characters
TITLE_TOO_SHORT	warning	3	Title under 20 characters
META_DESCRIPTION_MISSING	warning	8	No meta description
META_DESCRIPTION_TOO_LONG	warning	2	Over 160 characters
META_DESCRIPTION_TOO_SHORT	info	1	Under 70 characters
H1_MISSING	warning	8	No <h1>
H1_MULTIPLE	warning	3	More than one <h1>
CANONICAL_MISSING	warning	4	No canonical link
NOINDEX	error	25	noindex in meta robots or X-Robots-Tag
VIEWPORT_MISSING	warning	6	No viewport meta tag
LANG_MISSING	warning	3	No lang on <html>
THIN_CONTENT	warning	5	Under 300 words of visible text
IMAGES_MISSING_ALT	warning	1 each, max 8	Images with no alt attribute
OPEN_GRAPH_MISSING	info	2	No Open Graph title or image
STRUCTURED_DATA_NONE	info	1	No JSON-LD
NOT_HTTPS	warning	6	Final URL is not HTTPS
REDIRECT_CHAIN	warning	3	More than 2 redirects
SLOW_RESPONSE	warning	3	Server took over 2 seconds

A page that cannot be fetched (HTTP error, network failure, not HTML) scores 0 with a single error explaining why. Informational rules such as CANONICAL_DIFFERENT are listed without points.

How to run a bulk SEO audit

1. Paste your URLs, one per line. The https:// is optional.
2. Click Start.
3. Sort by grade or score to find the weakest pages, and read the issues column for exactly what to fix.
4. Download JSON, CSV or Excel, or schedule the Actor and send results to Google Sheets, Slack, Make, n8n or Zapier.

{
    "urls": [
        "https://www.python.org/",
        "https://example.com/"
    ]
}

• urls: any public web pages. Redirects are followed.
• concurrency: how many pages are fetched at once. Keep it low for small sites.
• maxUrls: a safety cap on how many are audited.

How much does a bulk SEO audit cost?

Frequently asked questions

Does it crawl my whole site? No. It audits exactly the URLs you give it. To audit a site, list its URLs (from a sitemap, for example).

Does it run JavaScript? No. It reads the HTML the server returns, the same thing most crawlers see first. Pages that only build their content in the browser will look thin.

Why is a measured response time slow? It is measured from the data centre running the Actor, so it includes that distance. Use it to compare pages, not as a Core Web Vitals score.

Is the score a ranking prediction? No. It is a checklist of on-page basics. A high score does not guarantee rankings and a low one does not prevent them.

What happens when a page fails to load? It gets a row with grade F and a clear reason (HTTP error, network failure or not an HTML page).

Notes and limits

• The Actor identifies itself like an ordinary browser and does not read robots.txt for pages you explicitly list. Only audit sites you are allowed to.
• Internal and private network addresses are blocked.
