Technical SEO Forensic Audit
Stop guessing why your rankings are stuck. Get a developer-level breakdown of your site's health, speed, and crawlability in under 60 seconds.
Inputs
- Target URL (e.g., https://example.com/pricing)
- Primary Keyword (Optional) for relevance checking
Outputs
- Technical Health Score (0-100)
- Core Web Vitals Assessment (LCP, CLS, INP)
- HTTP Header & SSL Status
- Meta Tag & Heading Hierarchy Analysis
Interaction: Enter your URL and click Start Free Audit. The tool simulates a search engine crawler visiting your page and performs a series of high-level technical checks on your content and metadata to provide an immediate SEO performance score.
Example Result Summary
How It Works
A transparent look at the logic behind the analysis.
DNS & Server Handshake
We initiate a connection to your server to verify DNS resolution, SSL validity (TLS 1.2+), and initial server response times (TTFB).
DOM Parsing
Our scanner fetches the HTML document object model (DOM) to analyze semantic structure, including Header Tags (H1-H6), Meta descriptions, and Canonical tags.
Performance Simulation
We run a lab-based simulation of Core Web Vitals to measure Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) against Google's thresholds.
Heuristic Analysis
Finally, we cross-reference findings against 50+ known ranking factors to generate a prioritized list of actionable fixes.
Why This Matters
A comprehensive forensic scanner to analyze architecture, performance, and indexability in real-time.
Crawl Budget Efficiency
Ensuring Google spends its limited resources on your money pages, not redirect chains or 404s.
User Experience Signals
Core Web Vitals are now a direct ranking factor. Poor LCP or CLS can cap your visibility regardless of content quality.
Indexation Control
Preventing index bloat and ensuring your 'noindex' and 'canonical' tags are correctly implemented to avoid duplicate content issues.
Mobile-First Readiness
Verifying that your viewport settings and tap targets are optimized for Google's mobile-first indexing paradigm.
Key Features
HTTP Status Check
Identify 301 chains, 404 errors, and 500 server issues instantly.
SSL & Security
Verify TLS protocols, HSTS headers, and certificate expiration dates.
Core Web Vitals
Measure Largest Contentful Paint (LCP) and Layout Shifts (CLS) in a lab environment.
Meta Tag Validation
Check title lengths, descriptions, and robots directives for optimal CTR.
Architecture Depth
Analyze heading structures (H1-H6) for semantic logic and keyword placement.
Tech Stack Detect
Identify the CMS (WordPress, Shopify, etc.) and server technologies powering the site.
Sample Output
Input Example
Interpretation
The scanner successfully accessed the URL (Status 200). It verified a valid SSL certificate with modern TLS 1.3 protocol. The performance metrics indicate a fast site (LCP 1.2s) with stable layout (CLS 0.004). The SEO checks confirm a properly optimized title tag length and a correct self-referencing canonical tag.

}Common Use Cases
Quick Spot Checks
Validate a page's status code and meta tags before sending it to a client or stakeholder.
Pre-Deployment
Ensure new code pushes haven't accidentally broken meta tags or introduced heavy scripts.
Sales Prospecting
Generate instant value for prospects by finding critical errors live on a sales call.
Health Monitoring
Get peace of mind that your site is accessible, secure, and indexable by search engines.
Troubleshooting Guide
Scan Failed / Timeout
If your server blocks bot traffic via a WAF (like Cloudflare), our scanner might be denied. Whitelist our user-agent or run on a non-restricted environment.
Missing Elements (CSR)
This tool analyzes the initial HTML response. Content generated purely by client-side JavaScript (CSR) might not be fully detected without a full headless browser render.
Low Score False Positives
Sometimes a 'warning' for description length is intentional. Use your judgment; tools are guides, not absolute law.
CORS Errors
If checking resources across subdomains, ensure your Cross-Origin Resource Sharing (CORS) policies are correctly configured.
Non-200 Responses
If the tool returns a 403 or 503, checking from your local browser might work, indicating IP-based blocking on your server.
Pro Tips
- Always manually check your robots.txt file first. If we can't crawl it, Google probably can't either.
- Run audits on both Staging and Production to catch issues before they affect revenue.
- Don't obsess over a 100/100 score. Focus on 'Critical' errors that block indexing first, then move to optimization.
- Use this tool in conjunction with Google Search Console data. GSC gives you the history; this tool gives you the 'now'.
- Check for 'X-Robots-Tag' in the HTTP headers. Sometimes a page looks indexable in HTML but is blocked at the server level.
- Ensure your Canonical tag logic handles query parameters (e.g., ?session_id=) to prevent duplicate content.
Frequently Asked Questions
Is this tool completely free?
Yes, this version is free for unlimited use. We do not store your data or require a credit card.
Does this check the whole site?
This tool scans a single URL (the entry point) to provide a snapshot. For full site audits (10,000+ pages), you need enterprise crawling software like Screaming Frog or Lumar.
Why is the LCP score different from PageSpeed Insights?
This is a simulated lab test from a specific server location. Real-world user data (CrUX) depends on your actual users' devices and connection speeds.
Can I use this for JavaScript frameworks?
Basic analysis works, but for deep checking of React/Vue/Angular hydration issues, we recommend a specialized rendering audit.
How do I fix the 'Redirect Chain' warning?
Ensure your links point directly to the final destination URL (status 200), skipping any intermediate 301 hops.
