Web Scanner Tool

The web scanner tool crawls a target site to assess SEO quality, performance, and security posture. It follows links within allowed scope, respects robots rules, and records page-level signals such as title, meta description, canonical URL, headers, hreflang, and structured data. It detects duplicate titles, missing meta descriptions, canonical conflicts, and non-2xx responses.
Core calculations translate raw crawl data into actionable outputs: a health score, issue taxonomy (on-page, technical, performance, accessibility, security), and per-page issue lists. It also estimates load times, resources, and Lighthouse-like metrics such as First Contentful Paint and Total Blocking Time when available.
Who benefits: SEO managers, developers, content teams, and agencies. Unique value: integrated, multi-domain analysis, configurable crawl scope, and exportable reports. It supports datasets for large sites, provides change-tracking over time, and aligns with standard formats (JSON, CSV) for downstream workflows.
Core features include: URL input, crawl depth control, authentication support, resource extraction, audit rules for title, description, headers, markup, and canonical checks; issue filtering; and a consolidated report with the highest-priority issues first, along with recommended fixes and example snippets.
