Use HYPD to understand whether your optimizations actually worked.
Example Prompts
Check the changes made in the last 20 days. Did ROAS or profitability increase?
Compare performance before and after I paused that campaign.
What was the impact of switching to tROAS bidding?
Example: Change Impact Analysis
Prompt:
Check changes made in the last 20 days. What were the results? We're optimizing towards pROAS.
| Metric | Before | After | Change |
|---|
| ROAS | 2.81 | 2.37 | -15.7% |
| Cost/Conversion | $18.71 | $22.45 | +20% |
| Revenue | — | — | -26.1% |
Losers (Worse Profitability)
| Campaign | ROAS Change | Cost/Conv | What Happened |
|---|
| Search - DSA | 1.83→1.48 (-19%) | +$54 (+183%) | 481 aggressive keyword changes destroyed performance. Conv rate collapsed 3.31%→1.14%. |
| PMax - Tidy Titles | 3.30→2.82 (-15%) | +$3.95 | Conv rate dropped 6.07%→4.84% |
Winners (Improved Profitability)
| Campaign | ROAS Change | Cost/Conv | What Happened |
|---|
| Shopping - Catchall | 1.72→3.51 (+104%) | -$11.06 | Conversion rate doubled |
Recommendation
- Stop aggressive daily changes to Search - DSA
- Restore removed keywords from before Oct 18
- Shift budget from failing DSA to Shopping - Catchall
What HYPD Can Compare
| Analysis Type | Example |
|---|
| Before/after changes | ”Impact of last week’s optimizations” |
| Time period comparison | ”November vs October performance” |
| Bidding strategy changes | ”tROAS vs Maximize Conversions results” |
| Campaign experiments | ”How did the new ad copy perform?” |
Specify the date range and what you changed: “I switched to tROAS on Nov 1. Compare the week before and after.”
