Keywords are grouped by search intent — not just prefixes and suffixes.

🔵 Informational intent

Searchers want to learn something — how, what, why, when queries. Best for: blog posts, guides, tutorials, explainers, FAQs. These keywords build topical authority and top-of-funnel traffic. Lower conversion but higher volume. Great for new sites building authority.

🟡 Commercial intent

Searchers are researching before buying — comparing options, reading reviews. Best for: comparison pages, best-of lists, review articles, roundups. Mid-funnel traffic with strong monetization potential for affiliate sites. Keywords like "best X", "X vs Y", "X review".

🟢 Transactional intent

Searchers are ready to act — buy, sign up, download, book. Best for: product pages, landing pages, pricing pages, CTA-heavy content. Highest conversion rate, often most competitive. Keywords like "buy X", "X discount", "X free trial", "X near me".

🔑 How to use this output

Pick 1–2 keywords per cluster and create dedicated pages. Use the full cluster as semantic keywords within that page — not one keyword per page. Export as CSV and paste into Ahrefs, Semrush, or Google Keyword Planner to get real search volume data before committing.

❓ Question keywords

Question-format keywords often appear in Google's People Also Ask boxes. Ranking for these gets you featured snippets and extra SERP real estate. Create a dedicated FAQ section or short answer page targeting these questions. Especially valuable for voice search and AI search results.

📥 Exporting your keywords

Use the Download CSV button to export all keywords with their intent labels. Import into Google Keyword Planner (free) to get monthly search volumes. Or paste into Ahrefs / Semrush Keyword Explorer for difficulty scores. Sort by volume and filter by difficulty to find your best opportunities.

💡 Pro tip: Start with informational keywords to build topical authority, then add commercial and transactional pages once you have domain authority. A new site targeting "buy X" with zero authority will struggle, but the same site ranking for 20 informational articles in that niche can then compete for commercial terms much more effectively.
