Gotchas
Sites with aggressive bot protection (Cloudflare's challenge mode) might cause Anvil to fall back to weekly — we won't burn our reputation hammering them.Price changes are reported at the SKU level. If a competitor renames the SKU, Anvil treats it as a new SKU, not a price change.Ad-library data is sourced from public archives (Meta Ad Library, TikTok Creative Center). We don't run their ads ourselves, so no targeting data is exposed.
