Data-Driven Attribution (DDA) 2025

April 2025 GA4 update added which YouTube engagement to DDA’s signal set?

Playlist adds

Shares

Likes

Engaged-view engagements (EVEs)

EVEs record when a viewer watches at least 10 seconds and later converts. Including them helps DDA capture upper‑funnel video influence that never registers as a click.

GA4 requires at least ______ conversions in 30 days before enabling DDA.

3,000

1,000

50

300

Google sets a 300‑conversion floor so the model’s coefficients are statistically reliable. Below that, sampling noise would swamp the marginal‑credit calculations.

If DDA can't generate a model, GA4 falls back to ______ attribution.

Time decay

Linear

First click

Last click

The fallback prevents blank reports by reverting to the deterministic last‑interaction rule. You’ll see a notice in the Attribution workspace if this fallback occurs.

Aggregate identifiers rolled out in April 2025 aim to improve attribution while respecting ______ rules.

SEO guidelines

AMP

Privacy Sandbox

CLS thresholds

Aggregate identifiers let Google group cohorts without exposing user‑level data. They align with the Chrome Privacy Sandbox commitment to phase out third‑party cookies.

DDA recalculates historical data for the past ______ days when switched on.

365

30

90

7

A 30‑day backfill ensures you can immediately compare performance versus the previous model. Longer backfills remain subject to data‑retention limits.

Which channel grouping was newly supported by DDA in January 2025?

Legacy Gmail

Discovery Ads

Messenger

AMP stories

Discovery placements moved from last‑click only to multi‑touch modelling. This change surfaces their assist value in blended campaigns.

DDA weights a touchpoint by how much it raises the probability of ______.

Click

Conversion event

Session duration

Impression

The algorithm holds other factors constant and asks: ‘If this touch were removed, how would conversion likelihood change?’ That marginal lift becomes fractional credit.

Interaction recency is a ______ feature in the DDA model.

Language

Timing

Format

Device

Timing captures how recent a touchpoint is relative to conversion, reflecting decay without a fixed rule. It interacts with device and channel signals in the model.

Switching bidding to DDA typically lifts conversions by Google’s 2025 benchmark of ______.

≈ 1 %

≈ 6 %

≈ 50 %

≈ 25 %

Google Marketing Live 2025 aggregated 40 k accounts and found median +6 % conversions at flat CPA. Actual lift varies with channel mix and model readiness.

View‑through impressions get DDA credit only when Google has high confidence via ______ signals.

CLS

TTFB

Bounce rate

Modeled conversions

If clicks are missing, Google uses modelled conversions from consent‑mode gaps. Only impressions tied to a high probability of assist receive partial credit.

Starter

Review the basics.

Solid

Good job—refine for mastery.

Expert!

Outstanding performance.
