Website SEO Audit: On-Page Checker, Broken Links & Site Crawl

Run an on-page SEO audit on any list of pages, or crawl a whole site, and get one row per page with a score from 0 to 100, every issue found with its severity (error, warning, notice) and the raw facts behind each one: title and its length, meta description and its length, H1 and H2 headings, canonical URL, meta robots and X-Robots-Tag (indexable or not), hreflang alternates, JSON-LD structured data types, Open Graph and Twitter card tags, images without alt text, word count, internal, external and nofollow links, broken links, HTTP status, redirects, HTTPS, server response time and HTML size.

No browser and no login: the actor reads each page's HTML directly, follows internal links politely and respects robots.txt.

What you can use it for

• Agencies and freelancers: audit a prospect's site in a minute and send the issue list as a CSV or sheet with your pitch
• Site owners: a weekly scheduled run catches the page that lost its title, the template that dropped its H1, or the redirect that started returning 404
• Content teams: find thin pages, missing meta descriptions and images without alt text across the whole blog
• Developers: check a staging site before launch — noindex left on, canonicals pointing to the wrong host, missing viewport tag
• Lead generation: score hundreds of local business homepages and contact the ones that need help

Why this one

• $0.02 per page, half the price of the most used SEO audit actor in the Store, $0.001 per run start
• Score + issue codes: each page gets a 0–100 score and stable issue codes (title_long, h1_missing, noindex, broken_links, …) that are easy to filter, count and chart
• Broken link checker built in: turn on checkBrokenLinks and every link on the page is requested; failing ones are listed with their status
• Site crawl: give a homepage, turn on crawl, set maxPagesPerSite — the actor walks internal links on the same host (assets, PDFs and feeds skipped)
• Polite and honest: robots.txt respected by default, blocked or bot-check pages are flagged instead of being scored as empty
• 256 MB memory, about one second per page without link checks

The checks

Errors (−12 each): unreachable page, HTTP 4xx/5xx, bot-check or block page, missing title, missing H1, not HTTPS, broken links. Warnings (−6 each): title shorter than 25 or longer than 60 characters, missing meta description, noindex, missing viewport, images without alt, server response over 2.5 s. Notices (−2 each): meta description under 70 or over 160 characters, several H1s, missing or foreign canonical, missing lang, incomplete Open Graph, no JSON-LD, thin content (under 250 words), HTML over 1.5 MB, no favicon, invalid JSON-LD.

How much does it cost?

$0.02 per page audited on the Free plan plus $0.001 per run, with automatic discounts on paid Apify plans. Platform compute is included; broken-link checks cost nothing extra.

Worked examples:

• One prospect's homepage before a sales call: $0.021
• A 200-page site crawled with broken-link checks, weekly: $4 a week
• 500 local business homepages scored for outreach: $10

FAQ

Is this legal? Yes. It reads public web pages the way a search engine does, identifies itself, respects robots.txt by default and keeps a gentle pace. Audit sites you own, sites of clients who asked, or public pages for research. No login-walled content and no personal data are collected.

Does it render JavaScript? No. It audits the HTML the server sends, which is what most search engine checks start from. Single-page apps that build all their content in the browser will show low word counts; that is a real SEO finding.

How is the score calculated? 100 minus 12 per error, 6 per warning and 2 per notice, never below 0. The issue list is the real output; the score makes pages easy to sort.

Can I check only the links? Our Bulk URL Status Checker checks plain URL lists for status codes and redirects at a lower price.

Why was a page skipped? robots.txt disallowed it (turn respectRobotsTxt off only for your own site), it was already audited, or it is an asset (image, PDF, script).

Integrations
