Heuristic

Keep a clear expertise spine before widening your public topics

Range is useful after the reader can answer one simpler question: what do you reliably know?

When it fits

Your site or professional feed covers many unrelated themes and it is becoming difficult to tell what you are known for.

When to avoid it

A person may legitimately have multiple domains. The goal is navigable coherence, not artificial uniformity, and Google's guidance is not a numerical ranking rule.

Why it matters

Choose a small set of themes that share one expertise spine and let most public work reinforce it. Adjacent experiments can stay, but they should not make the main purpose unreadable. Google's guidance explicitly asks whether a site has a primary purpose or focus and warns against producing many topics mainly to capture search traffic. Apply that as a clarity constraint, not a niche prison.

An example

A professional can write about SAP data, AI-assisted knowledge work and migration reliability under a coherent spine of reliable enterprise change, while unrelated trend posts remain occasional.

Check your result

A new visitor can describe the core expertise in one sentence without ignoring half the recent work.

Keep this limit in mind

A person may legitimately have multiple domains. The goal is navigable coherence, not artificial uniformity, and Google's guidance is not a numerical ranking rule.

Supports

Google's current people-first guidance asks creators to provide original information or analysis, substantial added value, clear sourcing, demonstrable expertise and content with a primary audience purpose rather than producing many topics mainly for search traffic.

These are self-assessment principles and search guidance, not a deterministic ranking formula or evidence that any individual page will receive traffic.
