WriteGap generates topic cluster plans from any keyword in your brief: a hub article + 6–10 spoke articles targeting related long-tail searches. Each with search volume, difficulty score, and a one-click draft.
Hub + 6–10 spokes · volume per spoke · one-click drafts · status tracking
Google ranks pages, but it trusts domains. Publishing 10 tightly related articles signals that your site is an authoritative source on a topic — which lifts rankings for the hub keyword and all the spokes together.
The hub is a 2,000+ word pillar article targeting the primary keyword — written to rank for the head term and serve as the definitive guide. It links to every spoke. Because it covers the topic broadly, it also tends to pick up dozens of related long-tail queries that weren't specifically targeted.

links to: all 8 spoke articles
Each spoke article targets a related long-tail keyword — lower volume, lower difficulty, faster to rank. They link back to the hub. Traffic from 8 spokes compounds: each individual article might bring 300 visits/month, but together they bring 2,400 — plus they boost the hub's authority, which improves its position over time.

Publishing one article is easy. Publishing a complete, well-linked 10-article cluster takes weeks if you're doing it manually. Most competitors won't bother. Once your cluster is live and indexed, the internal link structure and topical coverage create a moat that holds rankings even when newer competitors enter the space.
Every opportunity card in the Brief tab has a "Build a cluster" button. Click it on any keyword — WriteGap uses that as the hub topic and generates the full cluster plan around it.
one click · Brief tabWriteGap generates the hub article plan (keyword, title, outline) and 6–10 spoke article plans — each with its own keyword, search volume, difficulty, and content angle. The cluster is saved to the Clusters tab permanently.

one draft per keyword · status trackingA topic cluster is a group of related articles organized around one central "hub" article (targeting a broad keyword) and several "spoke" articles (each targeting a related long-tail keyword). The hub links to all spokes; each spoke links back to the hub. This structure signals topical authority to Google — that your site covers a subject comprehensively — which improves rankings for the hub keyword over time. A strong topic cluster is one of the most durable SEO content strategies, because it's hard to replicate quickly.
From any keyword in your weekly brief, click "Build a cluster." WriteGap generates a hub article plan (targeting the primary keyword, 2,000+ word pillar format) and 6–10 spoke article plans targeting related long-tail searches — each with search volume, difficulty, and a content angle. All of this is saved to your Clusters tab. You can then generate drafts for individual spokes and the hub the same way you draft any article in WriteGap — one click per article.
No — it generates the plan for the whole cluster, then you draft articles one at a time on your own publishing schedule. Each spoke in the cluster has a "Draft" button. Once a draft exists for a spoke, the button becomes "Show draft" and takes you to it directly. This lets you ship articles weekly rather than trying to publish 10 articles at once.
Basic plan: 3 spokes per cluster (teaser — the plan shows the full set but only 3 are accessible). Growth plan: 6–10 spokes, unlimited clusters. Premium and Agency: 10 spokes per cluster, unlimited clusters. The number of spokes is set by WriteGap based on the keyword space — it generates as many as the topic supports, up to the plan limit.
Yes. Each spoke in the Clusters tab has a status dropdown: planned → draft → published. Update it as you ship each article. The cluster progress bar shows the ratio of published/draft/planned spokes so you can see how complete each cluster is at a glance.
Hub + spokes planned, volumes checked, drafts one click away. From €29.99/month on the Growth plan.
