Data Crawl Tool

Purpose & User Intent: This tool supports planning and documenting web data crawl workflows. Users include SEO analysts, data engineers, content strategists, and researchers who need structured crawl scopes, extractable data fields, and audit trails. It solves the problem of translating crawl goals into repeatable, verifiable crawl plans and reports. When a team must inventory sites, estimate crawl scope, or communicate methodology to stakeholders, this tool captures decisions and expected outputs.\n\nCore Logic & Features: Required features include seed URL input, crawl depth, domain filters, rate limits, user agent, data fields templates, and output schemas. Optional advanced features include multi domain aggregation, scheduling hints, exportable crawl templates, and compliance flags robots txt respect crawl delay awareness. The tool enforces data types URL integer depth boolean robots handling and validates inputs valid urls max depth at least 0. Outputs include structured plan documents and a tabular crawl report schema.\n\nInputs & Outputs: Inputs seed URLs array of strings sample https://example.com max depth int sample 3 include subdomains bool true obey robots txt bool true data fields array of strings sample title meta description export format string JSON or CSV Optional additional inputs crawl speed int requests per second time budget int minutes Outputs crawl plan JSON crawl summary string crawl report CSV or JSON.\n\nAlgorithms & Calculations: Uses breadth first crawl planning to determine page reach given depth and domain constraints. Derives estimates of crawl size based on seed URLs depth and domain breadth. Validation rules ensure seed URLs are reachable and that depth limits are non negative. No live crawling occurs in the tool it generates a plan.\n\nError & Edge Cases: Invalid seeds produce a named error missing required fields return specific error codes. If external data example robots txt is unavailable the tool logs a warning and uses default policy. Extreme depths or large seed sets produce limit warnings to prevent oversized plans.\n\nIndustry/Region & Localization: Supports ASCII Unicode URLs standard URIs and respects common international time formats for scheduling no currency handling involved Localization limited to language fields in outputs.\n\nAssumptions & Exclusions: Assumes access to seed URLs and network agnostic planning excludes executing actual crawl or data extraction Out of scope UI rendering real time monitoring or data transformation beyond the plan and report generation.
