Parameters
| Category | Explanation |
|---|---|
| Headless | Headless browsers provide automated control of a web page in an environment similar to popular web browsers, but are executed via a command-line interface or using network communication. |
| Mismatch | A mismatch between device indicators was found, for example: A Samsung S20 useragent with a 300×200 resolution while the normal resolution is 3200×1440 |
| iFrame | Our link was loaded in an iFrame. |
| No redirect (No JS) | We were unable to redirect the visit. This usually happens when Javascript is not enabled on the target device or the visit terminated within less than 0.1 seconds |
| Duplicate click | Two or more clicks on the same impression or click url. |
| Duplicate visit | Two or more clicks from the same useragent + ip combination within a very short amount of time. |
| No impression | The impression that should have made the click was never shown. |
| Late click (no invalidation) | Clicks coming in later than usual. However this is NOT a reason for us to invalidate the costs. |
| Expired click | The click happened more than 24 hours after the bidrequest was won. |
