Technical SEO audit · AI optimization audit
Paste a URL and we crawl the whole site for both ranking systems - classic technical SEO (broken links, titles, meta, schema, sitemaps, security, page speed, Core Web Vitals) and AI search readiness (llms.txt, structured data, semantic headings, content signals LLMs use). Free, no sign up, full XLSX export.
How the SEO + AI audit works
No black-box magic, here is exactly what happens when you click Start audit. The crawler runs the same deterministic checks a Technical SEO specialist would run by hand, then layers on the AI optimization signals that LLM-based search (ChatGPT, Perplexity, Google AI Overviews) actually reads, llms.txt, JSON-LD, semantic headings, content structure.
Top of this page. We accept any domain or full URL, example.com, https://example.com/, blog.example.com/post/. The seed becomes the starting point of the crawl.
On the run page, click Config to set max pages (default unlimited), max depth, request delay, custom sitemap URL, or a custom User-Agent. Skip it and we use sensible defaults.
Before the crawl starts, we read robots.txt for Sitemap: declarations, then probe 16 common paths. Found URLs are merged with the crawl so we see pages that have no internal links pointing to them.
Starting from the seed, we follow every internal link breadth-first. Each request includes our User-Agent and respects your delay setting. SSRF protection blocks private-IP fetches.
For each page we capture status, response time, title, meta description, headings, canonical, hreflang, robots directives, Open Graph, JSON-LD blocks, every <a> and <img>, security headers, inline tags (GTM, GA), and word count.
A live screenshot of the audited site appears with a scan beam overlay. The sitemap card lights up green the moment we find your sitemap. Stage tracker shows fetching → parsing → checking links → auditing schemas → scoring security → extracting brand → scoring report.
When the crawl finishes, the report panel opens on Dashboard with the headline numbers. Switch between 28 reports in the sidebar, every page has a plain-English explanation and a one-click jump to a related fixer tool.
Hit Export XLSX for a multi-sheet workbook, or Export CSV ZIP for one CSV per report. Both contain identical data, broken links, page list, images, schema, security, PageSpeed, tech stack and more.
Configuration
Every option lives behind a single Config button on the run page. Skip it and the audit uses the defaults below, they work well for 95% of sites. Open Config when you need to scope, throttle, or override.
The crawler is built with strict SSRF protection, respects request delays, and identifies itself with a clear User-Agent so your access logs stay readable.
Max pages
Unlimited (or any number you set)
Hard ceiling of 2,000 to keep one call from running forever. Set lower for a quick spot-check.
Max depth
Unlimited
Distance from the seed. Depth 1 = homepage + everything it links to. Useful to scope blog-only audits.
Request delay
0 ms by default
Bump this to 200-500ms if you are crawling a fragile site or want to be polite. Slower, but easier on the server.
Sitemap URL
Auto-detect, override available
Auto-finds your sitemap from robots.txt + 16 common paths. Override if your sitemap is at a non-standard URL.
User-Agent
MyToolStudioAuditBot/1.0
Customizable if your CDN blocks unknown bots, paste a Googlebot string and you are in.
Safety
SSRF-protected
Private-IP fetches (127.0.0.1, 10.x, 192.168.x, link-local) are blocked at the server level. Only public URLs are crawled.
What we audit
Built on the same kind of crawl engine your favourite paid SEO tools use, plus the AI-search readiness checks (llms.txt, structured data, semantic content) that most legacy audits skip. Free, no sign up, no daily limits, full XLSX + CSV export.
Start at the seed URL, follow every internal link breadth-first. Default crawls every reachable page; you can cap pages, depth, and request delay before you start.
We check robots.txt and 16 common sitemap paths automatically (sitemap.xml, wp-sitemap.xml, post-sitemap.xml, sitemap_index.xml, etc.). You can override with a custom URL in Config.
Every URL is tagged as crawl-only, sitemap-only, or in-both. See exactly which pages exist in your sitemap but no internal link points to them, the real orphans Google can't find.
While the crawl runs, see a real screenshot of the audited site with a sweeping scan beam on top, so you know we are looking at the right site.
Every 404, 410, 500 and redirect chain is collected with the source page so you know exactly where the bad link lives.
Missing, duplicate, too short, too long, flagged across the whole site with one-click jumps to a related tool that rewrites them.
Every image with its alt text, dimensions, format, and lazy-loading flag. Open straight in our bulk image compressor when you spot oversized files.
See every JSON-LD already present, then get pre-filled suggestions for what is missing, Article, Product, FAQ, Breadcrumb, LocalBusiness.
HSTS, CSP, X-Frame-Options, Referrer-Policy and friends graded A-F with a one-line explanation of every gap.
Lighthouse scores and Core Web Vitals (LCP, CLS, INP, FCP, TTFB) pulled from Google PageSpeed Insights for every key page.
Detected CMS, framework, analytics tags (GTM, GA4, Meta Pixel), CDN, hosting. Plus DNS records, WHOIS, SSL cert, email auth (SPF/DKIM/DMARC).
One click downloads the entire audit as a 12-sheet workbook, or a ZIP of CSVs. Identical data, hand it to a developer or a client.
While the SEO + AI audit runs
The loading screen isn't just a spinner. It is a real-time window into the technical SEO + AI optimization audit, site preview, sitemap detection, llms.txt probe, pages discovered, elapsed time, and a stage tracker so you always know what is happening.
A real, full-bleed screenshot of the audited site fills the left panel. A sweeping purple scan beam glides across so it visually feels like we are scanning the page.
Lights up green the moment we find your sitemap, shows the URL, the source (robots.txt vs. guess), and the URL count so you know exactly what is being merged with the crawl.
Fetching → parsing → checking links → auditing schemas → scoring security → extracting brand → scoring report. Each step lights up as the engine reaches it.
SEO + AI reports included
Open the side panel after the crawl and click any report. Classic technical SEO reports sit next to AI optimization reports (llms.txt, structured data, content signals) so you can fix ranking issues for both Google and the new AI search engines in one pass. Export everything as XLSX or CSV ZIP at any time.
Built for makers
Every audit runs once per request, the crawl results live in your browser for this session and disappear when you close the tab unless you click Save. We never persist your audited URL or its results on our servers.
