The same brand content can receive completely different treatment on Doubao, Qwen, and Yuanbao — this is not mysticism but source preference driven by user profiles.

QuestMobile Research Institute's Q1 2026 AI Application Insights states clearly: different AI platforms have distinct user profiles, which shape their content source preferences. China's AI native apps reached 446 million MAU, and each engine has its own character. This article compares source preferences across the six major engines so you can spend limited optimization budgets where they matter most.

The picture has only sharpened since. QuestMobile's 2026 first-half report (published 2026-07-14) shows China's AI-native apps reached 499 million MAU by May 2026, up 85.4% year on year, with Doubao at 382.3 million MAU in June 2026 (+172.1% year on year). The engines are growing into even more distinct audiences, which makes source-preference strategy more important, not less.

1. Source Preference Comparison Across Six AI Engines

Engine	MAU (Mar 2026)	User profile	Source preference	Optimization focus
Doubao	345M	Mass-market	Accessible, scenario-based content	Conversational question coverage, conclusion-first answers
Qwen	166M	Male-skewed	Hard technical parameter content	Parameter tables, comparison data, industry reports
DeepSeek	127M	Many technical users	Rigorous, argumentative content	Technical docs, whitepapers, open-source content
Kimi	Top tier	Strong long-text needs	Complete, structured long content	Deep articles, reports, FAQ systems
Yuanbao	Top tier	Developed-city users	WeChat official account articles	Official account matrix, WeChat ecosystem synergy
Ernie	Top tier	Broad ecosystem scenarios	Baidu-ecosystem linkage	Baijiahao and Baidu ecosystem content

These preferences are directional signals, not fixed labels. The same logic plays out on global platforms: Similarweb's May 2026 data puts ChatGPT at 52.7% of AI-platform web traffic, with DeepSeek and Claude also taking measurable share — each platform again drawing on different source mixes. A brand strategy built on "everyone reads the same content" is increasingly unrealistic.

2. Differentiated GEO Strategy: Allocating Content Assets by Engine

One Asset, Multiple Uses

The same content asset can be layered across engines: structured website pages serve all engines' crawling; official account versions focus on Yuanbao scenarios; parameter tables target Qwen and DeepSeek; deep long-form targets Kimi. Layered production with per-engine adaptation keeps costs manageable. The order matters too: build the universal layer first. A well-structured official site with FAQ pages is the foundation every engine draws from, so until that is solid, per-engine work produces diminishing returns. Treat each engine as an additional lens on the same corpus rather than a separate campaign — this also keeps measurement simple, since every mention traces back to the same underlying assets.

Priority Recommendations

Stage	Actions	Engines covered
Start	Website structure + core service pages + FAQ	All
Growth	Official account matrix + deep articles	Yuanbao, Kimi
Deepening	Technical parameter content + industry reports	Qwen, DeepSeek
Optimization	Cross-engine mention tracking and iteration	All

Measurement and Iteration

Build a cross-engine mention ledger: monthly, ask each engine the same brand questions and record "mentioned or not, position, context"; compare differences across engines and fill content gaps. See the GEO measurement guide for the full method. Use the ledger as the checkpoint between stages — per-engine work only pays off after the universal layer is solid.

3. Source-Preference Trends to Watch in 2026

Three trends from QuestMobile's H1 2026 data change how content should be produced:

Engagement is deepening on DeepSeek: MAU dipped 20.3% in the half, but per-user session time rose 109.8% — technical users are reading deeper. Long-form, argument-heavy documentation and whitepapers now earn proportionally more attention.
Preinstalled assistants are scaling: handset preinstalled assistants reached 755 million users, above any downloaded app. Short, mobile-first Q&A content that reads well in a phone assistant matters more than ever.
Qwen keeps climbing: from sixth to second place in the MAU ranking within a quarter (Q1 2026), Qwen's technical user base keeps demanding parameter tables and comparison data.

4. FAQ

With a limited budget, which engine should we optimize first? Start with Doubao: 345M MAU is the largest, question scenarios are broadest, and mass-market content heavily overlaps with basic website optimization — the highest ROI.

Can content be fully reused across the six engines? Not fully, but it can be reused in layers: structure, data, and facts are universal; wording is tuned per engine profile (add parameters for Qwen, strengthen official account formats for Yuanbao).

Does Ernie optimization conflict with other engines? No. Baidu ecosystem content (e.g., Baijiahao) and general website content can be built in parallel; the exact strategy depends on your existing Baidu-side presence.

Does differentiated optimization require a dedicated team? Not from day one. Execute the "start" stage with existing staff, then decide whether to bring in specialists once data accumulates. For a systematic plan, explore our GEO optimization service or contact us.

How do I know which engines my buyers actually use? Cross-check three signals: ask customers directly, review which AI platforms send referral traffic, and compare your audience profile against the user profiles above. Your measurement ledger will then tell you which engines to prioritize.
