Keyword Clustering Tool & Content Plan Generator

Turn a few seed keywords into a ready-to-execute content plan. Expand each seed into hundreds of related keywords, then automatically group them into topic clusters — each with total search volume, search intent, and a suggested content type.

What it does

1. Expands every seed into related keywords (with monthly search volume, CPC, competition).
2. Clusters them into topic groups by shared head terms.
3. Labels each cluster with intent (informational / commercial / transactional / local) and a suggested content type (blog guide, comparison, product page, local page).
4. Ranks clusters by total search volume — your content priority order.

What you get per cluster

• Cluster name + pillar keyword (the one to target with your main page)
• Total search volume across the cluster
• Intent + suggested content type
• The full keyword list (keyword, volume, CPC, competition) — your supporting/long-tail terms

Use cases

• Content calendars — one cluster = one pillar article + supporting posts.
• Site architecture — map clusters to hubs and spokes.
• SEO strategy — prioritize topics by real search demand.
• PPC ad groups — pre-grouped keywords for tightly-themed ad groups.

Pricing

$0.05 per seed keyword expanded + clustered, plus a $0.001 start fee. 5 seeds ≈ $0.25. No subscription, no API key.

Price change on 23 August 2026: a seed expansion moves from $0.05 to $0.13, so 5 seeds ≈ $0.65. The old price applies to every run until then. The increase brings the price in line with what expanding a seed actually costs — at the default 200 keywords per seed, the previous price did not cover it.

A minimum charge per run covers the data provider's fixed per-request fee. It only applies when you raise keywordsPerSeed well above the default, or when a seed returns very little data; on a normal run you pay the per-seed price above.

Example input
