Why This Matters

Google is grading your site — most of it is failing silently.

Every missing meta tag, broken canonical, or malformed schema is a ranking signal you're throwing away. And because nothing "breaks," nobody notices until traffic quietly disappears.

Missing Metadata

No title tag, no meta description, no canonical URL. Google falls back to guessing — and that guess is almost never your best foot forward. Click-through rate craters. You never know why.

40% of pages have suboptimal title tags (Ahrefs 2024)

Broken Schema & Open Graph

No structured data means no rich snippets. No Open Graph means your LinkedIn and X shares look like broken links. You're invisible where your customers already hang out.

Only 36% of top sites have valid JSON-LD schema

Silent Technical SEO Failures

Missing robots.txt. Broken sitemap.xml. HTTP redirecting to a 404. No HTTPS redirect. WWW serving different content than root. Every one of these tanks indexability — none of them trigger an error page.

23% of sites have broken canonicalization (Semrush 2024)

Full Coverage

Six detection engines, one unified SEO report.

Every audit runs the full battery of 37+ technical SEO checks. Each finding includes severity, a plain-English explanation, copy-paste HTML fix, and a link to the authoritative Google or schema.org documentation.

Metadata Analysis

Title tag length and keyword placement, meta description quality and character count, canonical URL validation, meta robots directives, charset, language declaration, viewport configuration, favicon presence.

8 checks · 25% weight

Heading Structure

Validates H1 presence and uniqueness, keyword inclusion, proper H1→H2→H3 hierarchy without skipped levels, heading count and distribution. Catches the #1 invisible SEO bug — sites with zero or multiple H1s.

4 checks · 15% weight

Content Quality

Word count against minimum thresholds, text-to-HTML ratio, image alt text coverage, internal and external link analysis, broken link detection within the crawled page. Content is what Google ranks — thin pages score poorly.

6 checks · 15% weight

Technical SEO

HTTPS/SSL validation, HTTP status codes, server response time, X-Robots-Tag headers, hreflang setup for internationalization, robots.txt existence and validity, sitemap.xml URL discovery, HTTP→HTTPS redirect, WWW canonicalization.

9 checks · 25% weight

Social & Sharing

Open Graph tags (og:title, og:description, og:image, og:url, og:type) for Facebook and LinkedIn previews. Twitter Card metadata for X (Twitter) previews. Catches the "why does my share preview look broken" problem instantly.

6 checks · 10% weight

Schema Markup (JSON-LD)

Detects presence of structured data, validates JSON-LD syntax, identifies schema types in use (Organization, WebSite, Article, Product, LocalBusiness, FAQPage, etc.). Rich snippets in search start here.

Google SERP Preview

Renders exactly how your page will appear in Google search results — favicon, breadcrumb, title, description. Desktop and mobile views side-by-side. Spot truncation, missing tags, and low-CTR titles before Google does.

Copy-Paste Fixes

Every failure ships with the exact HTML to drop into your <head> section. Missing meta description? Here's the tag. No Open Graph? Here's the block. Bulk-copy all fixes for one page in a single click.

37+ remediations

Multi-Page Audit

Audit up to 5 pages in a single run. Each page gets its own tab with independent scoring. Great for comparing your homepage, landing pages, and blog posts — or auditing before/after a fix.

How It Works

From URL to fixed SEO in four steps.

No signup, no credit card, no waiting for results. Here's the full flow:

Enter Any URL

Drop any public URL into the scanner — your homepage, a landing page, a blog post, or a competitor's site. Add up to 4 more pages to audit in the same run.

37+ Checks Run

Our Cloudflare Worker fetches the page, parses the HTML, and runs every check in parallel. Metadata, headings, content, technical SEO, social, and schema — all graded in under 60 seconds.

Prioritized Findings

Results grouped by category OR sorted by priority (critical → high → medium → info). See your SERP preview, site-wide diagnostics, and every failing check with its severity and impact.

Copy-Paste Fixes

Every failure includes the exact HTML or DNS change to fix it. Copy individual fixes or grab them all in one click. Re-run the audit, watch the score jump.

Built For

Who this SEO tool is for.

Whether you own one site or audit hundreds — if you care about ranking in Google, you need this in your workflow.

Founders & Solo Operators

You don't have an SEO agency on retainer. Run this before every major launch, after every content push, and whenever traffic dips. 10 minutes of fixes can recover months of lost rankings.

Marketing Agencies

Run this on a prospect's site before your discovery call. Walk them through the red flags. Close the retainer. When the deal lands, SiteCORE Agency handles the continuous monitoring at scale with white-label reports.

Content & SEO Teams

Audit new landing pages before publish. Check competitor pages to reverse-engineer what they're doing right. Build a pre-launch checklist. Every page you ship should score 80+.

Developers & Dev Teams

After a CMS migration, platform swap, or site redesign — things break silently. Schema gets dropped. Canonicals break. This tool catches what QA misses before Google notices. Integrate into your deploy checklist.

Free vs SiteCORE

This Tool Is Free. SiteCORE Goes Further.

The audit tool is always free. For continuous monitoring, automated weekly scans, change alerts, and multi-site dashboards — that's SiteCORE.

Honest answers about this free SEO tool.

No catch. The SEO Health Check is free forever — all 37+ checks, unlimited audits, up to 5 pages per run, SERP preview, copy-paste fixes, reference documentation links, and printable PDF reports. We ask for your name and email only when you want to export a professional PDF report. That's it. No signup to use the tool. No paywall to see results. If you like what it finds and want the automated continuous version, SiteCORE picks up where this leaves off.

This tool runs when you click the button. It audits up to 5 pages, runs 37 checks, and shows you a score with fixes. SiteCORE runs continuously in the background across your whole site, re-audits automatically every week, alerts you via email or Slack when SEO regresses, tracks scores over time, and covers things this tool doesn't — uptime monitoring, Core Web Vitals, full-site crawling, broken-link detection, change detection, and multi-site dashboards. Same DNA, bigger scope, always-on.

The overall score is a weighted composite across six categories: Metadata (25%), Technical SEO (25%), Headings (15%), Content (15%), Social & Sharing (10%), Schema Markup (10%). Each check within those categories has a priority rating (critical, high, medium, low) that influences how much a failure drags the score. Every check links directly to the official Google Search Central documentation, MDN, schema.org, or ogp.me so you can verify the logic yourself. This isn't opinion-based grading — it's standards-based.

Manual audit with this tool: monthly is fine for most sites, weekly if you publish content frequently, and mandatory before/after any major deploy, redesign, or CMS migration. Reality check: most people forget. That's exactly why SiteCORE exists — it audits automatically every week and only pings you when something actually breaks. If you find yourself forgetting to run the free tool, that's your signal to automate the monitoring.

Totally normal — most sites first-audit in the 40-60 range. Here's the order: (1) Fix anything marked "Critical" first — those are ranking blockers. (2) Fix "High priority" next — these impact CTR and indexability. (3) Add missing Open Graph and schema markup last — these affect how you appear in shares and rich snippets. Every failure in the tool includes copy-paste HTML you can drop into your page's <head> section. Fix, re-audit, watch the score climb.

Yes — this tool only reads public HTML, the same way Googlebot does. No authentication, no login attempts, no exploit probes. You can audit any public URL: your competitors, a prospect's site before a pitch, a reference site you admire. It's the SEO equivalent of viewing page source.

No — it complements them. Ahrefs and Semrush focus on keyword research, backlinks, and competitive intelligence. Screaming Frog is a full site crawler for massive enterprise audits. This tool is the middle: a fast, focused, per-page technical SEO audit with actionable fixes. Use it when you need a straight answer about "is this page technically sound?" in under 60 seconds without paying $99-$449/month.
