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" (关键词无展现). 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:
1. Task creation & query setup
2. Detailed diagnosis results
3. Specific optimization recommendations
4. Basic account information
5. 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准入 (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.
