Frequently Asked Questions
How many URLs fit one audit batch?
Paste or upload hundreds of URLs per batch; the backend paces ~15 checks per minute with auto-resume on 429s. A 500-link pre-migration audit completes in about 35 minutes — start it, keep the tab open, export the CSV once.
What does the results table catch?
2xx success, 3xx redirect targets and chains, 4xx client errors, 5xx server failures, plus timeouts and DNS misses. Sort by status: fix 404s first (lost rankings), then chains over 2 hops (diluted link equity).
Will target sites block the scan?
Checks come from shared backend IPs with polite pacing, so aggressive firewalls may 403 some URLs that load fine in browsers. Re-check flagged URLs manually before reporting them dead to clients.
Is my URL list uploaded anywhere?
URLs pass through the status backend for checking (unavoidable — statuses live on those servers), and results are never stored. The CSV export counts as one Pro download (signed-in free: 2 a day).
What batch sizes and retries does the scan use?
Lists cap at 5,000 URLs and are sent in batches of 45; each batch gets up to 3 attempts, waiting the Retry-After seconds on a 429 (~20s default, capped at 65s) before retrying the same batch. The summary flags responses over 1,500ms as slow.
