# SimilarWeb Traffic Batch

Normalizes and deduplicates up to 1,000 domains or URLs, then processes them asynchronously with bounded concurrency. Temporary service failures are retried automatically, up to three total runs per domain. Poll the returned status URL until completion; successful domains are charged once and no-data results are not retried.
