Semantic clusters & topical authority
Stéphane Jambu industrialises topical authority for e-commerce sites: cluster architecture, internal linking and production at scale. 1,300+ semantic clusters shipped for 650+ brands — field calibration, not theory.
Short definition
A semantic cluster is a set of pages organised around a topic, connected by a hierarchical internal linking structure: a parent page, child pages and support content. Built well, it signals the site's topical authority over an entire category to Google.
Why this topic matters
- Topical authority has become a core factor for ranking durably in a competitive e-commerce category.
- A well-structured cluster can strongly grow traffic: one column documents +123% after deployment.
- The same topical authority feeds visibility in AI engines: a thorough, structured site is more readily cited.

Stéphane's method
- Map a category's semantics exhaustively before writing a single page.
- Define the cluster's page types — parent, child, support — and their role in the linking.
- Industrialise production with documented processes and calibrated teams, without losing quality.
- Deploy internal linking and track traffic growth over time.
- Reinvest the earned topical authority to also win in AI engines.
Frequently asked questions
What is a semantic cluster?
A semantic cluster is a set of pages organised around a topic, connected by hierarchical internal linking (parent page, child pages, support content). It helps Google understand a site's topical authority over a category.
What is topical authority?
Topical authority is a site's perceived legitimacy on a theme, built by covering a topic exhaustively and in a structured way. Semantic clusters are one way to industrialise it at scale.
How many clusters has Stéphane Jambu shipped?
More than 1,300 semantic clusters shipped for 650+ brands, providing a field calibration base rather than a theoretical one.
Does a semantic cluster really grow traffic?
Yes, when well structured. One column documents +123% traffic after deploying a semantic cluster. Results depend on the sector, the competition and the quality of execution.
