How It Works

Audit any website in three steps

No setup, no installation, and no login required. Enter a URL, run the crawl, and download results.

STEP 01

Enter URL & Configure

Paste any website URL. Configure crawl depth, speed, delay, user-agent, and enable sitemap discovery or JS rendering as needed.

STEP 02

Watch the Crawl Live

The crawler discovers pages in real-time, collecting status codes, titles, meta tags, links, canonicals, structured data, and security headers.

STEP 03

Review & Export

Browse audit results across 33+ analysis pages. Export everything to a 24-tab Excel workbook for client reporting or team collaboration.

Audit Modules

Everything the crawler analyzes

Each module provides deep analysis of a specific SEO factor with actionable data you can export.

Full Site Crawling

Crawl websites with configurable depth, speed, delay, and user-agent settings. Watch pages get discovered in real-time with live progress and crawl statistics.

Adjustable crawl depth and max pages
Custom user-agent string support
Rate limiting to avoid target overload

Page Titles & Meta

Audit every page title and meta description across the crawl. Detect missing, duplicate, too-long, and too-short tags with instant character-count validation.

Missing title detection
Duplicate title grouping
Character length validation

Headings Analysis

Check heading hierarchy (H1-H6) across all crawled pages. Find missing H1 tags, multiple H1s, and structure issues that affect content readability.

Security & Privacy

How your data is handled

Crawl data is stored locally in your browser while you use the tool - nothing is sent to our servers beyond proxy requests.
The backend proxy only fetches pages you request so the browser can read HTML across origins. No pages are stored server-side.
Rate limiting and configurable delays help avoid overwhelming target websites during the crawl process.
You can clear all crawl data at any time by closing the tab or using the reset function.

Accuracy & Reliability

Built for professional audits

Automatic retries for temporary 5xx errors to reduce false "broken page" reports in your audit results.
Canonical-aware deduplication avoids double-counting URL aliases and keeps data accurate.
Configurable crawl speed and delays ensure stability even on large sites with thousands of pages.
Start with moderate settings and increase speed once the site responds reliably for best results.
Enable sitemap discovery for better coverage on large or complex site architectures.
