Action > Reason > Impact Decisioning
Every call is a complete decision. You see the action, the reasoning, the expected impact, and the documents and learnings that informed it.
#1247
A.R.I. · Acquisition · PMax
Action
Switch bid strategy from Target ROAS to Max Conversion Value on the ‘Catalog · Branded’ campaign.
Reason
18 conversions over the last 30 days against Google’s
30-in-30 rule1. Smart Bidding needs the conversion-volume floor before tROAS can perform.
Impact
Unlock delivery for 2-4 weeks. Expected lift on impression share between 12 and 28 points based on prior batch
measurement2.
#1283
A.R.I. · Efficiency · Search
Action
Lower target_roas on the ‘Catalog · Generic’ campaign from 320% to 240%.
Reason
Target is 92% above trailing 30-day actual ROAS. The bidder pulls bids on auctions it doesn’t expect to clear at this
target1.
Impact
Restore eligible volume in 5-10 days. Expected conversion-volume lift of 18-32% as the bidder re-stabilizes against the new
target2.
#1304
A.R.I. · Visibility · Search
Action
Add 9 missing sitelink assets to the ‘Lifecycle · Subscription’ campaign at the account level.
Reason
Ad Strength is ‘Average’ with 1 of 6 sitelink slots filled. Asset coverage is the highest-leverage
Quality Score1 lift available.
Impact
Expected lift on expected CTR of 0.4-0.9 points. Quality Score lift typically follows within 7-14 days based on prior
measurement2.

Sample answer
Cortex · answering with 7 sources
When should I switch a Search campaign from Maximize Conversions to Target ROAS?
Google's documented threshold is at least 15 conversions with reported values in the last 30 days[1]. Before that, Target ROAS lacks enough signal to optimize against and will typically underspend the budget[2].
Once you cross the threshold, set the initial target_roas within ±15% of your trailing 30-day actual ROAS[3]. Setting it more aggressive at switch-over is the most common cause of immediate volume drops - Google's bidder will pull bids on auctions it judges unlikely to clear the target[4].
If conversion values vary widely (e.g. ecom with a wide AOV distribution), enable value rules for first-time vs returning customers before switching[5], otherwise tROAS will optimize toward whichever segment carries the higher average value.
Plan for a 2-week learning period with no structural changes[6]. The Cortex Bidding Sentry will alert if CPA spikes > 25% beyond historic mean during the transition.
