# Best practices

> Pre-launch checklist for publishers integrating the Kontext SDK.

Work through this checklist before going live. Each item links to the relevant guide or concept page.

1. **Use the latest SDK version.** We ship improvements — fill-rate fixes, new ad formats, performance, support for new DSPs and demand partners — on a steady cadence. Pin to the current major and update minors regularly. See [Changelog](/resources/changelog).
2. **Pass every message through `addMessage`.** Every user message is a preload opportunity for the SDK to fetch an ad — passing all of them **can significantly improve fill rate.** When you want to mute a specific turn, use `trackOnly: true` rather than skipping the call. See [Messages](/concepts/messages).
3. **Collect IFAs.** IDFA on iOS, GAID on Android. Both improve retargeting, frequency capping, and revenue. See [IFA & ATT](/guides/ifa).
4. **Host `ads.txt` / `app-ads.txt`** with our authorization line, and **keep it up to date.** Whenever we add new demand partners or change our seller-domain, we'll send you an updated line — append it promptly so new DSPs can actually bid on your traffic. See [ads.txt](/guides/ads-txt).
5. **Integrate a TCF v2.2 CMP** for EU / UK traffic. Required by GDPR and dramatically improves fill rate — most DSPs won't bid without a valid consent string. See [TCF & CMP](/guides/tcf-cmp).
6. **Configure SKAdNetwork** on iOS. DSPs running install campaigns rely on SKAN attribution to measure performance — without their identifiers in your `Info.plist`, they have less data to bid aggressively on your traffic. See [SKAdNetwork](/guides/skadnetwork).
7. **Let us pace it.** We've seen what works across our network and tune cadence per publisher. Tell us during onboarding — no app-side rules needed. Per-message `trackOnly` remains available for finer control. See [Pacing](/concepts/pacing).
8. **Work closely with us on ad design.** Great ads come from collaboration — share your style, brand constraints, and any content red lines so we can tune the creative to feel native to your app. The best-performing ads are the ones users love. Reach out via [Support](/resources/support) any time.
