Topic Clusters

Topic Clusters groups raw keywords around a central pillar topic with five to fifteen supporting topics and wires the internal links, turning scattered articles into topical authority on the subjects your brand wants to be known for.

How it works

Drop in raw keywords from any source: your own list, questions mined by Ranko, an export from another tool, or a strategy-meeting brain dump. Ranko identifies the central pillar topic a natural group belongs to, names it, and shows the rationale. It then attaches five to fifteen supporting topics that a real authority would also cover. Five is the floor for credibility and fifteen is the ceiling for focus, so anything beyond fifteen splits into a related pillar. Finally, Ranko maps the internal linking: pillar down to supports, supports back up to the pillar, and sideways links between related supports. You can rename, merge, or edit pillars and placements at any time.

Key capabilities

• Pillar topic detection with a named pillar and visible rationale.
• Supporting topic discovery within a five to fifteen range, splitting overflow into new pillars.
• Raw keyword grouping from any source and shape of input.
• Cross-cluster internal linking generated automatically, including adjacency links between clusters.
• Authority depth scoring that compares cluster coverage against competitors who rank for the pillar.
• A cluster to brief pipeline that turns the pillar and supports into structured article briefs.
• Edge-case handling so no keyword is left orphaned, with primary placement and secondary relevance flags.
