RRL Checker

The RRL Checker analyzes redirect behavior for a given seed URL to identify performance and SEO risks associated with redirect chains. It computes the redirect map by following HTTP Location headers and standard 3xx responses up to a configured maximum depth, reporting each step with URL, status code, and position in the chain. It also flags loops, excessive depth, missing or inconsistent status codes, and potential misconfigurations that waste crawl budget or degrade user experience. Conceptually, redirects are a graph: sources and destinations are nodes, and redirects are edges. The algorithm traverses the graph, detects cycles, computes chain length, and estimates the impact on crawling efficiency. Outputs include a linear chain, a map suitable for visualization, and warnings when thresholds are exceeded. This is valuable for SEO analysts, web developers, migration engineers, and site owners.\n
Core features include seed URL input, a maximum depth setting, and options to include or ignore query strings; the tool can constrain results to a host or allow cross-host redirects. Outputs are exportable as CSV or JSON, and can be integrated into pipelines or reports. The tool helps diagnose legacy redirect rules, plan site migrations, and ensure clean URL architectures. Real-world use cases include validating staging to production redirects, auditing third-party redirects, and monitoring redirects after CMS changes.
