# Topic Cluster Gap Visualizer

> Enter your main topic and existing content to map subtopic coverage and visualize the gaps you should fill for topical authority.

**Category:** Content Strategy

## How it works

The Topic Cluster Gap Visualizer runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full content strategy audit.

1. Provide the input this tool needs — a URL, a block of text, or a keyword list, depending on the tool.
2. The tool processes it and renders the result visually or as a structured list.
3. Use the output to prioritize what to fix or build next.
4. Export or copy the results for your own tracking sheet.

**Why it matters:** Content that wins in 2026 is built around topical completeness and genuine expertise signals, not word count. Planning content around entities and topic clusters — rather than isolated keywords — is what actually builds the topical authority search engines reward.

This is a free, interactive, browser-based tool — no signup required. It runs client-side JavaScript, so this Markdown page describes what it does; [use the live tool](https://iliassami.com/tools/topic-gap-visualizer) to actually run it.
