Some sites are hard to crawl by following links alone. They may rely heavily on JavaScript navigation, hide links behind interactions, or block automated browsers. When a capture comes back with only one screen or none at all, BenchCanvas can fall back to the site's sitemap. ## How it works If the initial capture is too thin, BenchCanvas automatically looks for the site's sitemap and uses it to discover pages to capture. This often recovers a useful flow when ordinary link-following falls short. The fallback runs automatically, so in most cases you do not need to do anything. When it is available, you may also see controls to trigger or adjust the sitemap-based capture. ## When it still does not help A few sites cannot be captured well even with the sitemap, usually because they aggressively block automated browsers. In that case: * Try the [Chrome extension](/extension/capture-from-browser) to capture from your own browser session. * For logged-in or interactive flows, [record a video](/capture/video-to-flow) and import it. * Review [Troubleshooting captures](/capture/troubleshooting) for more options. The sitemap fallback improves coverage but does not guarantee a complete flow. You can always [add screens manually](/capture/add-screens) or [expand the flow](/capture/expand-flow) to fill gaps.
