URL Info

URL Info is an advanced website analysis tool that performs comprehensive scans of URLs to reveal technical details, security configurations, performance metrics, SEO factors, and server infrastructure. Unlike basic link checkers, URL Info conducts deep inspection covering: HTTP response analysis (status codes, redirects, response times), HTTP headers (security headers, caching policies, server identification), SSL/TLS certificate details (validity, issuer, encryption strength), DNS information (IP addresses, nameservers, DNS propagation), Server technology detection (web server, programming language, CMS, frameworks), Content analysis (meta tags, page titles, descriptions, Open Graph data), Security assessment (HTTPS enforcement, security header configuration, vulnerability indicators), Performance metrics (page load time, resource size, compression, caching effectiveness), SEO factors (meta tags, structured data, robots.txt, sitemap), Social media integration (Facebook Open Graph, Twitter Cards), and Accessibility features. This tool is invaluable for: web developers troubleshooting site issues, SEO professionals auditing websites, security analysts assessing configurations, competitive researchers analyzing competitor sites, and quality assurance teams verifying deployment. URL Info consolidates information from multiple specialized tools into one comprehensive report, saving time and providing holistic website intelligence.

Enter the full URL (including http:// or https://) experiencing issues. For '404 Not Found' errors: Check HTTP status code in results - 404 confirms page doesn't exist. Verify URL spelling, check if page moved (look for redirect information), examine server configuration for routing problems, and review .htaccess or web server rules. For redirect loops ('Too many redirects'): URL Info traces the redirect chain showing each hop. Look for circular redirects (A→B→A) or excessive chains. Common causes: conflicting redirect rules, HTTPS/HTTP misconfiguration, www/non-www redirect conflicts, or CDN configuration issues. Fix: Simplify redirect rules, ensure HTTPS redirects don't conflict with other redirects, clear browser cache and CDN cache. For slow loading: Check performance metrics in results - response time, resource sizes, compression status. High response times (>500ms) indicate server performance issues or geographic distance. Large uncompressed resources (no gzip/brotli) waste bandwidth. Lack of caching headers forces repeat downloads. For mixed content warnings: Results show if HTTPS page loads HTTP resources (images, scripts, stylesheets). Modern browsers block mixed content causing broken functionality. Fix: Update all resource URLs to HTTPS or relative URLs. For SSL errors: Certificate details reveal expiration, name mismatches, untrusted CAs, or weak encryption. For SEO issues: Check meta tags section - missing title/description tags harm search rankings, duplicate content indicators, missing Open Graph data affects social sharing. For email delivery problems: Examine DNS records and SPF/DKIM configurations shown in results. The comprehensive report helps correlate symptoms with root causes, guiding targeted fixes.

Technology stack identification: URL Info reveals competitors' technical infrastructure without accessing their code. Server details show whether they use Apache, Nginx, IIS, or specialized servers (LiteSpeed, Cloudflare), indicating budget and technical sophistication. CMS detection identifies WordPress, Drupal, Shopify, Magento, custom solutions - showing platform investments and capabilities. Programming languages (PHP, Python, Ruby, .NET, Node.js) appear through various headers and fingerprints. Frameworks and libraries (React, Angular, Bootstrap, jQuery) visible through loaded resources. CDN usage (Cloudflare, Fastly, AWS CloudFront, Akamai) indicates global reach and performance focus. Infrastructure insights: Hosting providers identified through IP ownership and server headers (AWS, Google Cloud, dedicated hosting, shared hosting). Multiple domains on same IP suggest cost-conscious shared hosting vs. dedicated infrastructure. Security maturity: Presence of advanced security headers (CSP, HSTS, Feature-Policy) indicates security investment. Missing basic headers suggest immature security practices. SSL certificate type (DV, OV, EV) and CA choice reflect security priorities. SEO and marketing strategy: Meta tags reveal target keywords and positioning. Open Graph implementation shows social media marketing sophistication. Structured data (Schema.org markup) indicates advanced SEO efforts. Google Analytics, Tag Manager, or alternative analytics reveal tracking tools. Performance priorities: Compression, caching, and CDN usage show performance optimization level. Resource sizes and load times benchmark against your site. Business intelligence: Track changes over time (platform migrations, infrastructure upgrades, feature additions). Identify partners (third-party services integrated). Assess market positioning through content and technical sophistication.

2xx Success codes: 200 OK - request succeeded, normal page load. 201 Created - resource successfully created (API responses). 204 No Content - request succeeded but no content to return. 3xx Redirect codes: 301 Moved Permanently - resource permanently moved to new URL in Location header. Search engines transfer SEO value. Use for: site migrations, URL structure changes, domain changes. 302 Found (Temporary Redirect) - temporary redirect, original URL maintained in search indexes. Use for: A/B testing, temporary maintenance pages, location-based redirects. 307 Temporary/308 Permanent - like 302/301 but preserve HTTP method (POST stays POST). 4xx Client Error codes: 400 Bad Request - malformed request syntax (invalid parameters, bad JSON). 401 Unauthorized - authentication required but not provided. 403 Forbidden - server understood request but refuses (permissions issue, IP blocking, file permissions). 404 Not Found - resource doesn't exist. Fix: correct URL, restore deleted content, implement redirects for moved pages, create custom 404 page with navigation. 429 Too Many Requests - rate limiting triggered. 5xx Server Error codes: 500 Internal Server Error - generic server malfunction (script errors, configuration problems). Check server logs for details. 502 Bad Gateway - proxy/load balancer received invalid response from upstream server. 503 Service Unavailable - server temporarily overloaded or under maintenance. 504 Gateway Timeout - upstream server didn't respond in time. Troubleshooting approach: 4xx errors = client/request problem (fix the request). 5xx errors = server problem (fix server configuration or code). URL Info shows exact status code helping diagnose whether issue is on your end or server end.

Critical security headers to verify: Strict-Transport-Security (HSTS) - If missing or weak, implement: Strict-Transport-Security: max-age=31536000; includeSubDomains; preload. Forces HTTPS for all connections preventing protocol downgrade attacks. Content-Security-Policy (CSP) - Absence leaves site vulnerable to XSS attacks. Implement: Content-Security-Policy: default-src 'self'; script-src 'self' https://trusted-cdn.com; object-src 'none'. Restricts resource loading to trusted sources. Start with report-only mode: Content-Security-Policy-Report-Only to test before enforcing. X-Frame-Options - Missing allows clickjacking attacks. Add: X-Frame-Options: DENY (prevent all framing) or SAMEORIGIN (allow same-site framing only). X-Content-Type-Options - Should be: X-Content-Type-Options: nosniff preventing MIME-sniffing attacks. Referrer-Policy - Control information leakage: Referrer-Policy: strict-origin-when-cross-origin balances privacy and functionality. Permissions-Policy - Restrict dangerous features: Permissions-Policy: geolocation=(), microphone=(), camera=(). SSL/TLS configuration: Verify certificate validity, expiration dates, strong cipher suites (TLS 1.2+), and proper certificate chain. Information disclosure: Server header revealing specific versions (Server: Apache/2.4.41) enables targeted exploits. Remove or genericize: Server: Apache or remove entirely. X-Powered-By exposing PHP/ASP.NET versions should be removed. CORS configuration: Overly permissive Access-Control-Allow-Origin: * on authenticated APIs is dangerous. Restrict to specific trusted origins. Cookie security: Ensure cookies use Secure, HttpOnly, and SameSite attributes. Action plan: Compare URL Info results against security benchmarks (OWASP recommendations, Mozilla Observatory), prioritize missing critical headers, test changes in staging, and monitor with regular URL Info scans.

Response time analysis: URL Info measures server response time (Time to First Byte - TTFB). Benchmarks: <100ms - Excellent (local or highly optimized servers). 100-300ms - Good (acceptable for most sites). 300-600ms - Fair (consider optimization). >600ms - Poor (significant improvement needed). Slow TTFB causes: database query optimization needed, unoptimized server-side code, inadequate server resources (CPU/RAM), geographic distance to server (use CDN), lack of caching (implement opcode cache, object cache). Compression analysis: Check Content-Encoding header. gzip compresses text resources 60-80%, brotli achieves better compression (10-15% smaller than gzip). Missing compression wastes bandwidth and slows loads. Implementation: Enable in web server config (Apache mod_deflate, Nginx gzip module). Caching optimization: Examine Cache-Control headers. Static resources (CSS, JS, images) should have long max-age: Cache-Control: public, max-age=31536000, immutable. Dynamic content needs shorter TTLs: Cache-Control: private, max-age=3600. ETag and Last-Modified enable conditional requests reducing transfer for unchanged resources (304 Not Modified responses). CDN usage: Headers revealing CDN (X-Cache, CF-Cache-Status, X-Served-By) indicate performance investment. CDNs reduce latency through geographic distribution. HTTP/2 or HTTP/3: Modern protocols multiplex requests, compress headers, and enable server push. Check protocol version in URL Info. Upgrade to HTTP/2 (requires HTTPS) provides 20-40% performance improvement. Resource size: Large unoptimized images, bloated JavaScript/CSS hurt performance. Redirect chains: Multiple redirects (A→B→C→D) add latency (200-500ms per hop). Minimize redirects by updating links to point directly to final destination. Optimization workflow: Benchmark current performance with URL Info, identify bottlenecks (slow TTFB, missing compression, no caching, redirect chains), implement fixes, re-test with URL Info to confirm improvements, monitor ongoing performance.
