How long are visit records kept, and why might a day be missing?

SignalLane keeps two kinds of attribution data. Visit records (each landing visit and each order SignalLane saw) are kept for 30 days. Daily totals (the figures on the Attribution page) are kept for 400 days. The records are what an order is joined to; the totals are what you read.

What the 30 days mean for attribution

An order is credited to a landing visit by the same shopper up to 30 days before it. A visit record that has been deleted cannot be joined, so the window is never longer than the records are kept. An order whose landing visit was older shows as following no tracked visit.

Days with a "not recorded" banner

When reports arrive faster than SignalLane accepts them, during a sale or a campaign peak for example, some are not recorded. The Attribution page and Home then show a warning headed Some visit reports were not recorded (or Some visit reports or orders were not recorded) that names the days, in UTC: "On … (UTC), SignalLane did not record some visit reports because they arrived faster than it accepts them."

Why a day can be low with no banner

• Shoppers declined tracking, or their browser blocks it.
• The shopper's browser closed or lost its connection before the report was sent.
• Traffic was blocked before it reached SignalLane, for example as suspected automated traffic.
• The app embed or the pixel was off. The setup guide on Home says whether both are on.
• It was simply a quiet day. A day with nothing tracked is a row of zeros, never a missing row.

Other records

The Broken links record keeps up to 50,000 pages, dropping a page nobody has reached for 400 days. For the full list of what SignalLane stores and for how long, see what SignalLane stores.

Days are UTC days

Daily totals are counted midnight to midnight UTC, so a day on the Attribution page may start in the evening or the morning of your own clock. The page says where. Choosing dates.
