}

Every item has the same keys; a value Similarweb does not show for that site is null (or an empty list). A small site Similarweb knows but cannot estimate has hasTrafficData: false.

Domains Similarweb does not track, and domains that fail, are listed in the ERRORS record of the key-value store and are not billed.

Pricing

Notes

• The data is Similarweb's public (signed-out) website overview; snapshotDate is the month it describes.
• Similarweb's free page reveals only some traffic-source and referral shares; the others are null.
• Visit history covers the last 3 months, as on Similarweb's public page.
