Keyword zero impressions is one of the most frustrating problems in search advertising. Your ads are approved, your bids are competitive, and yet — nothing. No data. No clicks. No way to know what went wrong.
Baidu just added a diagnosis tool specifically for this: "Keyword Zero-Impression Diagnosis". It is now live on the platform.
Here is what it does — and why it matters differently for domestic vs. overseas advertisers.
What the Tool Does
The Keyword Zero-Impression Diagnosis tool examines why your keywords are not showing ads. It runs across five dimensions:
- Task creation & query setup
- Detailed diagnosis results
- Specific optimization recommendations
- Basic account information
- Client operation analysis
The tool diagnoses your keywords across all stages of the ad delivery pipeline:
- Account-level settings
- Keyword-level settings
- Targeting filters
- Quality thresholds
- Competitive win rate
- Whether keywords are low-efficiency terms
It also lets you choose your diagnostic period: today, last 2 days, or last 3 days.
The Optimization Output
After running the diagnosis, the tool delivers:
- Diagnosis conclusions — why keywords are not showing
- Analysis results — account-level, keyword-level, and operation-level findings
- Actionable recommendations — specific steps on targeting, creatives, landing pages, and bidding
This is a significant upgrade from the old approach: manually reviewing search term reports, guessing at causes, and iterating blind.
The Four Existing Diagnosis Tools
Baidu rolled out a series of intelligent diagnosis tools in 2025. This new tool joins:
- Project-level spending fluctuation diagnosis — why did costs spike?
- Over-cost diagnosis — are you burning budget on poor performers?
- Plan-level spending fluctuation diagnosis — is your campaign spending stable?
- Keyword zero-impression diagnosis (new) — why are my keywords not showing?
Together, these cover the main failure modes in Baidu search advertising.
🎯 Key Takeaway
- ✅️ Baidu's diagnosis tools are genuinely useful for performance optimization
- ⚠️ You need an active Baidu account to access them
- ⚠️ Overseas companies cannot open Baidu accounts directly
- ✅️ BPP manages Baidu accounts for overseas companies — we run these diagnostics for you
The Catch: You Need Account Access
If you are running Baidu ads from outside China, you likely have one of two setups:
- Through a Chinese partner or agency: They may or may not be running these diagnostics. You are not in control.
- Through BPP: We manage your Baidu account directly. When keywords stop showing — and they will — we run the diagnosis tool, identify the root cause, and fix it.
Keyword zero-impression issues are common after:
- Campaign structure changes
- Budget reallocations
- Quality score fluctuations
- Competitor bid increases
Without the diagnosis tool, fixing these requires experience and guesswork. With it, the fix is faster and more precise.
What BPP Does
BPP-managed Baidu accounts get proactive performance monitoring. When data looks wrong — keywords not showing, costs unexpectedly high — we run the relevant diagnostic tool and act on the output.
You do not need to speak Chinese, understand Baidu's platform quirks, or have a Chinese colleague on call. We handle it.
