Keyword Research: The Complete Process (From Requirements to Execution)
Chapter 2: Search Fundamentals · Question 20
Keyword research is not "coming up with a few words off the top of your head"—it is a systematic process that starts from business requirements, validates with data, and ultimately lands as a content plan. Doing keyword research well is equivalent to drawing a roadmap for your entire SEO strategy.
Why is keyword research the starting point of SEO?
- It determines what content you need to write
- It determines who your content can reach
- It determines how high your traffic ceiling is
Starting to write content without keyword research is like hitting the road without a map—you may go far, but in the wrong direction.
The Complete Process: 6 Steps
Step 1: Clarify business goals and user personas
Before opening any tool, answer these questions first:
- What problem does my product/service solve?
- Who are my target users? How do they describe their needs?
- What will users search for before purchasing/deciding?
- What do I want to achieve through search traffic? (Customer acquisition, brand awareness, market education?)
Step 2: Build a seed keyword library
Collect initial keywords from the following channels:
| Source | Method |
|---|---|
| Your own business | Product names, service names, industry terminology |
| User research | Customer service records, community questions, verbatim quotes from surveys |
| Competitor websites | See which keywords competitors rank for and what content they have written |
| Search engine | Baidu autocomplete, related searches, “People also ask” |
| Industry communities | Popular questions on Zhihu, high-frequency topics on Tieba |
The goal of this step is "broad coverage and large volume"—do not filter yet; collect 50-200 seed keywords.
Step 3: Expand and quantify with tools
Input seed keywords into professional tools to obtain data such as search volume, competition level, and related long-tail keywords.
Recommended tool combinations:
| Tool | Purpose | Suitable scenarios |
|---|---|---|
| 5118 | Long-tail keyword mining, demand mapping, trend analysis | The top choice for Chinese SEO, with comprehensive data |
| Baidu Index | Search trends, audience personas, geographic distribution | Validate demand heat and seasonality |
| Baidu Keyword Planner | Search volume estimates, competition level | Requires a Baidu Promotion account |
| Ahrefs | Competitor keyword analysis, keyword difficulty assessment | Leans toward English but Chinese data is growing |
| Site owner tools/Aizhan | Authority queries, keyword ranking monitoring | Free, suitable for preliminary assessment |
| Google Keyword Planner | Search volume in overseas Chinese markets | For Chinese-language sites targeting Google |
| Answer The Public | Question-type keyword discovery | Finding content angles |
Step 4: Classify and group
Organize the collected keywords by the following dimensions:
and group them bysearch intentClassification:
Take songbing.com.cn (a content site focused on Chinese organic marketing / AI searchSEO) as an example:
- Informational: users want to learn knowledge (e.g., "what is GEO", “what is organic traffic”) → corresponds to on-site
what-is-geo/、what-is-organic-marketing/Q&A pages like these - Navigational: users are looking for a specific website/brand (e.g., "songbing 100 questions", “songbing.com.cn”) → corresponds to the homepage and directory pages
- Transactional: users are ready to act (e.g., "organic marketing training", “SEO managed services”) → if service pages are built in the future, use service pages to capture these
- Investigational: Users are in comparison-decision mode (e.g., "SEO vs GEO", “What's the difference between AEO and GEO”) → map to
ai-summary-vs-traditional-ranking/、what-is-geo/this type of comparison Q&A
Layer by business priority:
- core keywords(directly tied to conversion) → prioritize homepage/product pages to capture
- secondary keywords(indirectly tied) → use category pages and topic pages to capture
- long-tail keyword(traffic supplement) → cover one by one with blog articles
Step 5: Assess difficulty and set priorities
Not every keyword is worth pursuing right away. Evaluate using three metrics:
| Metric | How to judge |
|---|---|
| Search volume | Whether monthly search volume justifies the content cost |
| Competition difficulty | What are the domain authority and content quality of the top 10 results |
| Business relevance | Whether the traffic from this keyword can convert |
Prioritize: keywords with moderate search volume + low competition + high business relevance. These are often long-tail keywords or niche-scenario keywords.
Step 6: Turn into a content plan
The end goal of keyword research is not an Excel sheet, but anexecutable content schedule:
- Each target keyword maps to one piece/group of content
- Specify the page type that captures each piece of content (homepage/category page/article page)
- Set publish dates and priorities
- PlanInternal linksrelationships (which articles link to each other, which point to core pages)
A real case: how songbing.com.cn does it
Take songbing.com.cn as an example. Its keyword research for the "Chinese organic marketing" topic follows this approach:
种子词:非付费营销、AI搜索优化、GEO
→ 扩展(用5118/百度指数挖长尾):
什么是GEO、GEO和SEO的区别、AI搜索怎么优化、
怎么让AI推荐我的品牌、小红书搜索排名怎么做、
新闻稿营销技巧、内容去重怎么处理...
→ 分类(按意图):
- 信息型(什么是GEO/什么是自然流量)→ 写成"XX是什么"问答页
- 调研型(GEO和SEO区别/AEO是什么) → 写成对比型问答页
- 实操型(怎么让AI推荐我/怎么做小红书排名)→ 写成步骤型教程页
→ 落地:101 篇问答按 6 个章节组织,全部汇聚在 /100wen/ 目录页
This is the complete real-site walkthrough of the "6-step process" above: seed keywords expanded into 101 question-type keywords → each question maps to one Q&A → organized by chapter → aggregated on a directory page. You can also see that every article title on the site is itself a keyword (e.g., "What Is GEO?", "The Correct Use of Content Deduplication and Canonical Tags").
Advanced supplement: a practical 3-step keyword library build + 4-layer demand segmentation method
The methodology below comes from a hands-on breakdown on the author's WeChat Official Account. It is more "engineering-oriented" than the general process above, and is especially suited to content sites building a keyword library from scratch:
3 steps to build a keyword library:
- Multi-channel keyword expansion (start with 500+): Use Baidu Index to see trends, 5118 to mine long-tail keywords, and site owner tools to check industry keywords; analyze the traffic keywords of the top 3 competitors; crawlZhihu/Tieba high-frequency questions to supplement "user's own words"-type demand
- Data cleaning: Remove obscure terms with monthly search volume below 50, highly competitive terms whose first page is dominated by major sites, and terms unrelated to the business; retain 300-400 effective terms that are "easy to rank for and high-converting"
- Classify and document: Use a spreadsheet to tag each term with "search intent + landing page type" to form the master keyword list
4-tier demand segmentation (corresponding to 4 page types, using songbing.com.cn as an example):
| Tier | User characteristics | Keyword examples | Landing page | Optimization focus |
|---|---|---|---|---|
| Awareness stage | Seeking information | “What is organic marketing”, “What is GEO” | Q&A page (e.g., /100wen/what-is-geo/) | One-sentence definition + structured content |
| Consideration stage | Comparing differences | “What is the difference between SEO and GEO”, “What is AEO” | Comparison Q&A page (e.g., /100wen/ai-summary-vs-traditional-ranking/) | Table comparison + pain point resolution |
| Decision stage | Clear action | “How to get AI to recommend my brand”, “How to rank in Xiaohongshu search” | Step-by-step tutorial page (e.g., /100wen/get-ai-to-recommend-your-brand/) | Practical steps + copyable checklist |
| Repurchase stage | Existing user extension | “How to handle content deduplication”, “How to use Canonical tags” | Advanced topic page (e.g., /100wen/canonical-tag-deduplication/) | In-depth topic + related recommendations |
Key point:The decision stage has the highest conversion rate(Organic search conversion rate is about 5%-8%), prioritize optimizing this layer when the budget is limited; the repurchase layer has a higher conversion rate but requires long-term operation.

Practical recommendations
- Update the keyword library once per quarter: Search demand changes with the market; new terms keep emerging and old terms may become outdated. Set a fixed cadence (e.g., the start of each quarter) to rerun the data and capture new opportunities.
- Don't just look at search volume—look even more at "winnability": A term searched 100,000 times a month but whose top 10 are all big sites is worse than a term searched 500 times a month with zero competition (the "100,000 times/500 times" above are illustrative numbers, not real statistics). New sites especially should start with low-competition long-tail keywords.
- Keyword research must be coordinated with the content team: The research results must be turned into a content brief handed to writers, including target keywords, search intent, reference competitor content, and expected content structure; otherwise, no matter how good the research is, it won't be implemented.
