Bulk On-Page SEO Audit - 26 Checks, Meta Robots, Hreflang

What is Bulk On-Page SEO Audit?

Bulk On-Page SEO Audit crawls a list of pages and scores each one across 26 on-page checks, then hands back a 0–100 score, a letter grade, and a severity-ranked issue list you can act on.

It is deliberately pure HTTP — no headless browser. That single design choice is why it runs at roughly 12,000 pages per hour instead of a few hundred, and why it is affordable enough to point at an entire sitemap rather than a handful of landing pages.

Every page also gets technology detection from 235 signatures, so the same run tells you which CMS, analytics, payment and tag-manager stack sits behind the site.

Pages that fail to fetch are still returned with their httpStatus and an error field — the run stays successful, you see a complete record, and you are not charged for them.

What can this Actor do?

• ✅ 26 on-page checks — titles, meta description, headings, canonical, robots directives, Open Graph, images, links, language, viewport and more
• ✅ 0–100 score with a letter grade so you can rank pages against each other at a glance
• ✅ Severity-ranked issues — every finding carries a severity, so fixes sort themselves
• ✅ Tech stack detection (235 signatures) with a tunable confidence floor
• ✅ Sitemap input — point it at a sitemap.xml and let it expand the URL list
• ✅ No browser — cheap, fast and stable at thousands of pages per hour
• ✅ Runs on the Apify platform: schedule it weekly, push results through a webhook, or pull the dataset from the API — monitoring, retries and storage are handled for you

How to use it

1. Open the Input tab.
2. Add pages to startUrls, or paste plain URLs into urls, or point sitemapUrls at one or more sitemap.xml files.
3. Set maxPages to the ceiling you are willing to pay for (default 20000).
4. Click Start and collect the dataset as JSON, CSV or Excel.
5. Sort by score ascending to get your worst pages first.

{
  "startUrls": [{ "url": "https://example.com" }],
  "concurrency": 24,
  "maxPages": 20000,
  "includeTechStack": true
}

Pricing

This Actor is pay-per-event. You are billed per page successfully audited — never per request, never per minute, and never for pages that could not be fetched.

Event	When it is charged	Price
Page audited	A page was fetched, parsed and scored	$25 per 1,000 pages ( = $0.025 each )
Actor start	Once per run, per GB of memory	$0.00005 per GB

Pages that fail to fetch or produce no output are not charged. Apify's BRONZE, SILVER, GOLD, PLATINUM and DIAMOND plans reduce the unit price automatically.

Rough budgeting, assuming every page audits successfully:

Pages in	Cost
1,000	$25
5,000	5 × $25
10,000	10 × $25

If half your URLs 404, your real bill is roughly half of that.

Input

Field	Type	Default	Notes
startUrls	array	example.com	Request objects, e.g. { "url": "..." }
urls	array	empty	Plain URL strings
sitemapUrls	array	empty	Sitemaps to expand into page URLs
concurrency	integer	24	Parallel page fetches
timeoutMs	integer	12000	Per-request timeout
maxPages	integer	20000	Hard cap per run
includeTechStack	boolean	true	Run technology detection
minTechConfidence	integer	60	Minimum confidence for a tech match

Output

One dataset item per audited page:

{
  "inputUrl": "https://example.com",
  "finalUrl": "https://example.com/",
  "httpStatus": 200,
  "score": 82,
  "grade": "B",
  "issues": [
    { "check": "meta-description", "severity": "medium", "message": "Missing meta description" }
  ],
  "techs": [{ "name": "Cloudflare", "category": "cdn", "confidence": 90 }]
}

Unreachable pages keep inputUrl and httpStatus and add an error field, so nothing silently disappears from your report.

FAQ

Do I need a browser to audit JavaScript-rendered pages? No, and that is the trade-off: this Actor reads the server's HTML. That covers the overwhelming majority of on-page SEO issues and is what makes the throughput — and the price — possible.

What does the score mean? It is a weighted 0–100 composite across all 26 checks, mapped to a letter grade. Use it to rank pages against each other, not as an absolute SEO guarantee.

Can I audit a whole site? Yes — pass the sitemapUrls field and raise maxPages. Start with a small maxPages on the first run to see what a full site costs you.

What if a page times out? It is returned with an error field and is not billed.
