Compare using sitemaps to discover URLs versus crawling a website page by page. When should you use each approach?
This page compares Sitemap Extraction and Web Crawling using the documented strengths, limitations, and practical fit recorded for each option. Descriptive claims are kept separate from measured benchmarks; a benchmark is shown only when its test conditions are available.
Choose Sitemap Extraction when your priority is instant access to all urls — one api call.
Choose Web Crawling when your priority is discovers all linked pages, even without sitemaps.
