Fetch Google Autocomplete for seed + all 26 alphabet modifiers (`seed + a`, `seed + b`...) 2. Fetch Google Autocomplete for question variants (`how to {seed}`, `best {seed}`, `{seed} for`) 3. Fetch PAA (People Also Ask) questions from SERP 4. Fetch Related Searches from bottom of SERP 5. Check Reddit for community language around the topic ### Phase 2: Intent Classification For each keyword, classify search intent: - **Informational (I)** — `how to`, `what is`, `guide`, `tutorial` - **Commercial (C)** — `best`, `top`, `review`, `vs`, `compare`, `alternative` - **Transactional (T)** — `buy`, `price`, `cheap`, `discount`, `hire`, `service` - **Navigational (N)** — Brand names, specific URLs ### Phase 3: Cluster & Prioritize Group semantically related keywords into clusters (hub-and-spoke): - **Pillar keyword** — broad, high-volume, 1-3 words - **Cluster keywords** — specific, long-tail, 3-6 words, support the pillar - **Quick wins** — low competition, clear intent, actionable now ### Phase 4: Output Report Produce a structured report saved to `3_MEMORY/seo_data/keyword_research_{domain}_{date}.md`: ```markdown # Keyword Research Report Domain: {domain} Topic: {seed} Date: {YYYY-MM-DD} ## Top Clusters | Cluster | Pillar Keyword | Volume Est. | Intent | Priority | |---------|---------------|-------------|--------|----------| | ... | ... | ... | ... | ... | ## Long-tail Opportunities | Keyword | Intent | Estimated Volume | Notes | |---------|--------|-----------------|-------| ## Questions (PAA) - ... ## Content Gaps (vs competitors) - ... ``` --- ## Rules - ALWAYS start with Tier 1 free sources. - NEVER fabricate search volume. If unavailable, mark as `Est: Unknown`. - Group keywords into a maximum of 10 clusters per run. - Flag keywords with ambiguous intent as "Mixed Intent — verify manually". - Save all outputs to `3_MEMORY/seo_data/` with timestamped filenames. --- ## Activation Examples - "Tìm keyword cho topic X" - "Keyword research cho website về Y" - "Content gap giữa mình và competitor Z" - "Long-tail keyword cho bài viết về A" - "Cluster keyword cho chủ đề B"
