1Introduction
AI Keyword Expansion is a SEO long-tail keyword mining tool that expands 30-200 Chinese long-tail words around a core word, covering five dimensions: question-type, scenario-type, region-type, comparison-type, and long-tail type. It supports four search engines (Baidu, 360 Search, Sogou, Google) and six industry adaptations (general, e-commerce, education, healthcare, technology, finance), making the keyword pool more aligned with your business scenarios. PRO members can view keyword tables grouped by dimension, see estimated search volume and competition level (high/medium/low) badges for each word, and export CSV with one click to directly import into webmaster tools. Free trial after login; subscribe to unlock 200 words and all data dimensions.

3FAQ
What's the difference between the free version and PRO?
After login, the free version can expand 30 plain-text keywords daily; PRO unlocks 50/100/200 words, tables grouped by dimension, search volume and competition estimates, and CSV export.
Are the estimated search volume and competition accurate?
Search volume and competition are estimated by AI based on industry experience (high/medium/low), for quick screening and batch ordering; for official campaigns, we recommend cross-checking with actual data from webmaster tools.
How to choose dimensions more effectively?
For content topics, check "Question"; for local customer acquisition, check "Region"; for building a long-tail keyword pool, select all. If none are checked, AI covers all dimensions.
Can the exported CSV be directly imported into webmaster tools?
Yes. The exported CSV contains four columns: word, dimension, estimated search volume, and competition. It is UTF-8 encoded (with BOM) and can be directly opened and imported into Excel and mainstream webmaster tools.
Why are there duplicate or similar words generated?
AI tries to deduplicate, but similar expressions are inevitable in long-tail words; we suggest viewing by dimension group and filtering manually, or checking fewer dimensions to focus the keyword pool.
