About This Tool

The Web Spider Tool crawls a target domain to enumerate URLs, discover page relationships, and collect health signals such as HTTP status codes and redirects. It builds a crawl graph that helps analysts assess site breadth and detect blockers. The tool supports depth-limited crawls and export-ready reports for SEO and technical audits. It is designed for teams needing repeatable, auditable crawl runs across multiple sites or migrations.

Conceptually, the tool traverses links in a controlled order, normalizes URLs, and records discovery time, final status, and content depth. It honors robots.txt by default but can be configured to override rules for testing. Outputs include a structured crawl_report in JSON/CSV, a summary of health signals, and optional sitemap recommendations based on discovered URLs. The approach emphasizes data quality, deduplication, and actionable diagnostics rather than raw page-by-page content. Use cases include pre-migration validation, sitemap completeness checks, and ongoing technical SEO monitoring. Unique value lies in integrated export formats, URL-level health signals, and crawl-budget-aware metrics that translate directly into optimization actions.

Frequently Asked Questions

Find Quick Answers

What data does the crawl collect?

The crawl collects discovered URLs, final HTTP status codes, redirects, redirect chains, content depth, canonical hints, and error signals. Exports include a JSON/CSV crawl report, broken links list, and sitemap suggestions for remediation planning.

Can I crawl very large sites?

Yes. The tool supports configurable max_pages and crawl depth, with backoff and throttling to respect server load. For very large sites, use incremental crawls or scheduled runs to manage resources and keep data fresh.

What formats are available for outputs?

Exports are available in JSON and CSV formats for the crawl report, with optional downloadable sitemap suggestions. Reports are designed for programmatic consumption and integration with SEO dashboards.

Does the crawl honor robots.txt by default?

Yes. By default the crawl respects robots.txt. It can be configured to override rules for testing or debugging, but this should be used cautiously to avoid policy violations or server overuse.
