# Ketch cookie banner: speed and features on Script tag

Data permissioning platform with a hosted consent experience.

- Vendor: Ketch
- Website: https://www.ketch.com
- Version tested: Hosted
- Framework: Script tag

We measured other CMPs on Next.js only, so on Script tag this comparison uses Ketch’s other integrations. [Ketch on Next.js](https://cookiebench.com/benchmarks/ketch.md).

## Desktop

Desktop profile: 1365 × 768 · No CPU slowdown · 12.5 MB/s, no added latency.

In our tests with its Script tag integration, Ketch showed its cookie banner in a median 1.65 s on desktop. It delayed the main content by 0 ms. Accept responded in 24 ms and Reject in 16 ms. It held trackers back in all 4 consent checks.

On an emulated mid-tier phone, the banner took 7.52 s. Per vendor docs, Ketch supports IAB TCF, IAB GPP, Google Consent Mode v2, Google CMP certification and Global Privacy Control.

| Question | Answer | How it compares | Context |
| --- | --- | --- | --- |
| How fast does the banner appear? | 1.65 s | 4th fastest of 6 Ketch integrations | Median of 15 visits. |
| Does it slow the page down? | 0 ms | Joint 2nd of 6 Ketch integrations, from least to most delay | Compared with the same page without a consent manager. There were too few paired visits to calculate an interval. |
| How fast does a click respond? | 24 ms | Joint 2nd fastest of 6 Ketch integrations | Reject responded in 16 ms. Under 200 ms feels instant. |
| Does it block trackers until consent? | 4 of 4 checks passed | All 6 Ketch integrations passed every check | No tracker ran and the page set no cookie before the visitor chose. |

### Known issues on desktop

- Its remote script or config changed during the run, so the run gives no confidence intervals for this cell. Differences are medians only.
