On-Page SEO Checker - Bulk Website SEO Audit

On-Page SEO Checker audits a list of URLs (up to 2,000 per run) and returns one row per page with an SEO score (0-100) and A-F grade, every issue ranked by severity with the exact fix, title / meta description / H1 checks, target-keyword placement, content depth, structured data, and technical health. Run it on a whole site's key pages in minutes and export to CSV, Excel or Google Sheets.

Built for SEO audits, agency client reports, pre-launch QA and monitoring pages after a release. From $0.006 per page ($6 per 1,000), no crawl limits, no subscription, no API key.

• 🧮 SEO score and grade per page: starts at 100 and loses points for each critical, high, medium and low issue, so a page with no H1 and no description cannot score an A.
• 🛠️ Prioritized fix list: every issue has a severity and a one-line fix, ready to paste into a ticket or client report.
• 🎯 Target keyword check: is the keyword in the title, H1, meta description and URL? Set one keyword for all pages or one per line (url | keyword).
• 📝 Page facts: title and description length, H1s, heading counts, canonical, word count, readability, internal / external links, images, Open Graph tags.
• 🧩 Structured data: lists the schema.org types found (Organization, FAQPage, Product, Article...) and flags pages with none.
• ⚡ Technical health: HTTP status, HTML fetch time, page size, render-blocking resources, compression, HTTPS, mixed content, broken links.
• 🌐 JavaScript rendering (optional) for React / Vue / single-page sites, with a browser-measured load time.
• 📊 Run summary: average score, the lowest-scoring pages, and the issues that repeat across most of your pages.

FAQ

How is the SEO score calculated? Every page starts at 100. Each critical issue costs 20 points, high 8, medium 4 and low 1. A score of 90+ is an A, 80+ B, 70+ C, 60+ D. The technical_score field also gives the crawler's own 0-100 health score for HTML, speed and markup.

Does it crawl my whole site? No. It audits exactly the URLs you give it, so you pay only for the pages you care about. To audit a full site, paste the URLs from your sitemap.

Why do I need JavaScript rendering? Pages built with React, Vue or Angular may show an empty shell without it. Turn it on when word counts or headings look empty.

Why was my page not audited? The domain does not exist, the site blocks automated requests, or it timed out. The row says which, and failed pages are not charged.

Is a high score a ranking guarantee? No. The score measures page-level SEO hygiene. Rankings also depend on links, competition and search intent.
