Tier 3 prevention for fashion stores
Stock
Experience-based: when top sizes/variants go out of stock, ROAS often drops even if ads are fine.
Promos
Promos can temporarily lift conversion rate. Log promo dates so you don’t misread performance.
Returns
Experience-based: returns can make “ROAS” look fine while profit drops. Track returns weekly when scaling.
Catalog/merchant risks (needs verification)
Needs verification: feed/merchant issues can reduce Shopping reach or stability during scaling.

Small-step scaling
Once stable:

- Why you changed it
- What you expected
- What happened
- What you’ll do next week

FAQ
Why does ROAS drop when I increase my Google Ads budget?
Because spend can drift to different products, different signals, and different inventory when budget expands. If segmentation, conversion goals, locations, placements, or tracking are off, scaling amplifies waste.
How do I stop Performance Max spending on random products?
Segment products so winners are protected and “budget eaters” don’t steal spend. For Performance Max retail, listing groups help control product eligibility.

Should Purchases be the only primary conversion goal for eCommerce?
In most scaling situations, yes. Primary actions are used for bidding; secondary actions are observation-only.
Google Help Source
How do I turn on enhanced conversions in Google Ads?

Google Help Source
How do I test if Google Ads conversion tracking works?
Use Tag Assistant and do a real test purchase to confirm Purchases records once and records correctly.
Google Help Source
What is considered a good ROAS for Performance Max?
It depends on margins, return rate, and your real cost structure.
How much should I spend per day on Google Ads when scaling?
Use small-step scaling plus stop conditions instead of chasing a magic number.
What should I fix first before increasing the budget again?
Fix Purchases-only goals and tracking reliability first, then product segmentation, then location/placements/signals.
