II. Baidu Zhidao Placement in Practice
Step 1: Discover target questions
- Enter your industry/product keyword into the Baidu search box and observe "Related searches" and "People also ask”
- 用5118或百度关键词规划师，筛选带"怎么样"“哪个好"“怎么选"“推荐"等后缀的long-tail keyword
- Search directly on Baidu Zhidao to find existing questions without quality answers
Step 2: The right way to ask and answer your own questions
Note: Baidu has detection mechanisms for self-asked, self-answered questions, so you need to avoid them:

- Wait 24-48 hours after asking before answering
- The asking account and answering account must not be linked in any way
- The answer content should feel human”—appropriately include personal experience descriptions
- After answering, have 2-3 accounts like it to increase impressions

- The first paragraph of the answer should naturally include the core keyword
- An answer length of 200-500 characters is best (too short has no value, too long users won't read)
- You can naturally mention the brand name at the end of the answer (do not put links, they will be deleted)

Zhihu's approach is more "heavyweight”, but the effect is also more lasting:
Topic selection strategy:
- Search industry keywords and find questions with more than 100 followers but fewer than <20 answers (low competition, high potential)
- Follow "brand name + how is it" type questions—these have the highest conversion rate
- Find questions that rank high but have poor answer quality—you can "intercept”" with high-quality content
Answering techniques:
- Word count: answers of 800-2000 characters carry the highest weight
- Structure: use bold headings to break into sections for easy reading; Zhihu's formatting has a positive impact on SEO
- Early upvote mechanism: upvotes received within 1 hour of publishing have the greatest impact on ranking—prepare mutual-upvote resources in advance
- Comment interaction: create 2-3 valuable discussions under your own answer to boost engagement metrics
- Continuous updates: update the answer content every 1-2 months; Zhihu gives "active answers" more impressions
Pitfall warnings:
- Zhihu's detection of marketing content is increasingly strict—do not force brand ads into answers
