Revenue reporting delay
Revenue reporting delay is the gap between a visitor clicking a feed ad and the arbitrageur seeing, and later confirming, the revenue for that click.
Ad platforms report spend almost in real time. Search feeds report earnings later. The delay has layers: a first estimate hours after the click, a revised estimate a day or two later once early invalid-click filtering has run, and a final figure after the month closes. Operators using a feed provider add that provider's own processing time. Tracker vendors describe the same pattern, offering "intraday" figures first and confirmed revenue afterwards.
The delay is a structural hazard in search arbitrage. Money is being spent now on the strength of what yesterday's clicks appeared to earn. A campaign can look unprofitable at noon simply because the morning's revenue has not arrived, and a rule that pauses it would be wrong. Equally, a campaign can look fine while its quality is collapsing, with the proof arriving weeks later as a clawback.
Operators cope in three ways: judging campaigns on time periods old enough for revenue to have settled; using modelled revenue per click for same-day decisions; and sending ad platforms an early estimated value so bidding algorithms are not starved of signal.
An example
Say by 14:00 a campaign has spent $400 and shows $280 of revenue, an apparent loss. If revenue typically takes about four hours to appear and the last four hours' spend was $130, the fair comparison is $280 against $270 of settled spend: roughly break-even, not a 30% loss.

Estimated revenue
Estimated revenue is the provisional earnings figure a search feed reports soon after clicks happen, before final checks for invalid traffic are complete.
Finalised revenue
Finalised revenue is the confirmed amount a feed will actually pay for a period, after invalid clicks and other adjustments have been deducted from the estimate.
Reporting API
A reporting API is a programmatic interface that lets software automatically fetch revenue, cost or performance data from a feed, ad platform or tracker.
Automation rules
Automation rules are if-then instructions that pause, restart or adjust ad campaigns automatically when chosen metrics cross set thresholds.
Attribution window
An attribution window is the period after an ad click or view during which a resulting conversion is still credited to that ad.
Clawback (revenue deduction)
A clawback is revenue a feed removes from a publisher's earnings after the fact, usually because clicks were judged invalid and the advertiser was refunded.
