Open Measurement SDK: the dependency that decides your in-app verification

Open Measurement SDK: the dependency that decides your in-app verification
Before you compare viewability vendors, understand that in-app, the verification only works if the publisher's SDK implements OMSDK (OMID). No OMID = modeled guesses.

✓ One SDK lets multiple verification vendors (IAS, DV, MOAT) read the same on-screen signal
✓ Eliminates the old per-vendor SDK wars inside the publisher app
✗ Adoption is uneven — programmatic in-app supply often lacks it
✗ You can't force a publisher to integrate it; you can only filter for it

The practical move: in your DSP/exchange, segment for OMSDK-measurable in-app inventory before optimizing on viewability at all. Otherwise you're optimizing on a model, not a measurement.

Verdict: treat OMSDK presence as a hard pre-filter, not a nice-to-have, for any in-app brand campaign.
Best for: programmatic brand buyers on in-app exchanges.
