Frequently Asked Questions
What is technical SEO?
Technical SEO is everything that helps search engines crawl, index, and render your site correctly — robots.txt directives, XML sitemaps, redirect chains, schema markup, HTTP security headers, hreflang tags, and Core Web Vitals. This toolkit audits all eight areas in a single scan.
How do I check my robots.txt file?
Enter your domain and the tool fetches your robots.txt automatically. It parses every directive, lists all blocked paths, highlights AI crawler rules (GPTBot, CCBot, Anthropic, etc.), and lets you test any URL against those rules — all inside the Robots.txt tab.
How do I validate my XML sitemap?
The Sitemap tab auto-discovers your sitemap via robots.txt or common paths, lists every URL with its last-modified date, catches duplicates, and flags issues like missing lastmod tags or oversized sitemaps. You can also generate a clean XML sitemap from scratch.
Does the tool check site security?
Yes — the Security tab performs a full HTTP security audit derived from your response headers. It grades twelve categories: HSTS, Content Security Policy, X-Frame-Options, Referrer Policy, Permissions Policy, X-Content-Type-Options, cookie security, CORS configuration, cross-origin policies (COOP/COEP/CORP), cache control, CDN detection, and mixed content. Every category gets an A–F grade with an exact fix snippet, and your overall score maps to a single letter grade shown on a circular gauge.
What is schema markup and why does it matter?
Schema markup (usually JSON-LD) tells search engines what your content means — articles, products, FAQs, and more. Valid schema unlocks rich results like star ratings, FAQ dropdowns, and recipe cards in Google Search. The Schema tab validates existing markup and generates new schemas for 14 content types.
How do I check redirect chains?
Paste your URLs into the Redirects tab and it traces every hop with millisecond timing. It flags chains longer than two hops, redirect loops, and broken endpoints — then generates clean redirect rules in Apache, Nginx, Next.js, Vercel, or Cloudflare format, ready to deploy.
What are hreflang tags and when do I need them?
Hreflang tags tell search engines which language or region a page targets, preventing duplicate-content issues on multilingual sites. You need them if your site serves content in more than one language or targets different countries. The Hreflang tab validates existing tags and generates them in HTML, XML sitemap, or HTTP header format.
What HTTP headers matter for SEO?
The Headers tab focuses on SEO-critical response data: canonical link, X-Robots-Tag, Content-Type, Content-Language, cache directives, and a full raw-headers view. Security-specific headers — HSTS, CSP, X-Frame-Options, and more — are graded separately in the Security tab with letter scores and fix snippets.
What are Core Web Vitals?
Core Web Vitals are Google's page-experience metrics: LCP (loading speed), INP (interactivity), and CLS (visual stability). The Web Vitals tab runs a PageSpeed Insights analysis and shows scores, per-metric breakdowns, opportunities, and diagnostics for both mobile and desktop.
How do I generate a robots.txt file?
Switch to Generator mode inside the Robots.txt tab. Add user-agent rules, block or allow specific paths, set a crawl delay, and list your sitemaps — then download the finished file with one click.
Can I use this tool for free?
Yes — 100% free, no signup, no rate limits. Analyze any public domain, generate config files, export CSV reports, and share results without spending a cent.
