Topic Cluster Generator With Built-In Anti-Cannibalization

Scattered articles tell Google and AI assistants nothing about what you master, and two pages on the same query cancel each other out. Sorank's topic cluster generator groups your keywords into SEO silos around a pillar topic, gives each silo a priority and checks for keyword cannibalization before you publish, so every new page strengthens the others.

Sorank keyword library: research topics with their number of categories and keywords, sourced from Search Console, competitors and GEO analyses

Your competitors own whole topics, not single keywords

The sites that keep showing up, in Google and in AI answers, rarely win with one article. They cover a whole topic with pages that support each other, while your blog stays a pile of posts that do not connect.

Sorank shows you who they are: the competitor ranking built from your weekly GEO analyses lists the domains AI assistants cite most, with their citations, visitors and keywords. Their keywords, your Search Console data and the questions AI models search feed your keyword library, organized by research topic. The topic cluster generator turns these isolated keywords into real topic coverage, one subject at a time.

Clusters built from real data, labeled by priority

Grouping hundreds of keywords by hand takes hours, and the result ends up in a spreadsheet nobody opens again. Worse, you still do not know which topic to start with.

Each research topic becomes your pillar, split into themed content silos. For an online coffee shop, that could be choosing a subscription, delivery and freshness, and gifts. Every keyword keeps its search intent, difficulty and volume, and every silo carries a priority, from P1 Core to P3 Exploratory. Filter by keyword difficulty and you know which silo to tackle first, and which keywords can wait.

Anti-cannibalization keeps every cluster clean

Keyword cannibalization happens when two of your pages target the same query: Google hesitates between them and neither ranks as it should. Most sites only notice it months later, when rankings drop.

Sorank runs an anti-cannibalization check while it builds the clusters, not after you publish. Each keyword is compared with those already grouped, overlaps are flagged inside the cluster, and each silo shows whether it is clean. Then select its keywords and send them to the Blog Content Planner, or generate the articles right away. Each page gets its own role in the silo, and your topical authority grows instead of splitting.

How it works

What is a topic cluster?

Gather keywords from three sources

Sorank pulls keywords from your Search Console, the competitors you follow and your weekly GEO analyses.

What is a pillar page?

Group them into prioritized silos

Each research topic is split into themed silos, with a priority label and a difficulty filter.

What is topical authority, and why does it matter for AI search?

Check for overlap, then plan

Overlaps are flagged inside each cluster. Clean keywords go to your calendar or straight into articles.

What you get with the cluster generator

  • A keyword library by research topic with the number of silos and keywords in each, and where they come from.
  • Themed SEO silos built around a pillar topic, ready to become topic clusters on your site.
  • A priority on every silo from P1 Core to P3 Exploratory, so you know where to start.
  • Intent, difficulty and volume on every keyword, with a keyword difficulty filter.
  • An overlap check that flags cannibalization inside each cluster before you publish.
  • A direct path to publishing send the keywords to your calendar or generate the articles in one click.

In a nutshell

Sorank's topic cluster generator structures your site around the pillar and cluster model. Keywords from your Search Console, the competitors you follow and your weekly GEO analyses are grouped into themed silos, each with a priority and a difficulty filter, so you know exactly what to tackle first. Anti-cannibalization runs while the clusters are built, not as an afterthought: overlaps are flagged before two of your pages can compete. The structure you end up with builds your topical authority on Google and in AI answers, instead of quietly competing with itself.

Take it further

Start from a wider keyword base with Keyword Research, and see the questions AI models search before they answer with AI Query Fan-out. Turn each clean silo into a publishing schedule with the Blog Content Planner, then into sourced articles with the Blog Article Generator. New to the topic?

Frequently asked questions

What is a topic cluster?

A topic cluster is a group of related keywords and pages that together cover one subject in depth: a pillar page for the broad topic, and cluster pages for its more specific questions, linked to each other. This structure helps Google and AI assistants see that a site covers a subject in depth, not just one query. In Sorank, clusters are organized as SEO silos built from your Search Console, your competitors and your GEO analyses.

What is a pillar page?

A pillar page is the main page of a cluster. It covers a broad topic and links to the more specific pages around it, which link back to it. It usually targets the most general keyword of the cluster, while the supporting pages answer narrower questions.

What is topical authority, and why does it matter for AI search?

Topical authority is the expertise a site shows on a subject by covering it fully and consistently, with pages that support each other. Google and AI assistants both have to decide which sources know a subject well enough to show or quote. A site that covers a whole topic with linked pages sends clearer signals than a set of isolated articles.

What is the difference between a topic cluster and a content silo?

A topic cluster is about meaning: the keywords and pages that cover one subject. A silo is about structure: how those pages are organized on your site, theme by theme, so each theme stands on its own. Sorank builds both at once: clean clusters, organized into prioritized silos without overlap.

Where do the keywords in each cluster come from?

From the same sources as your Keyword Research: your Google Search Console, the competitors you follow and the weekly GEO analyses Sorank runs across AI models, including the domains AI assistants cite in your market. Every cluster is grounded in real demand, not a brainstorm. Each keyword shows its intent, difficulty and volume, so you can decide what to tackle first.

How does anti-cannibalization work inside a cluster?

Before a keyword joins a cluster, Sorank compares it with the keywords already grouped there. If two terms would lead to two pages targeting essentially the same query, the overlap is flagged inside the cluster, before you publish anything. The check runs every time a cluster is built or updated, and each silo shows whether it is clean.

Do I need SEO experience to use it?

No. Sorank gathers the keywords, groups them into silos, labels their priority and flags overlaps for you. Your job is to pick the silo to start with and the keywords to publish. The priority labels and the difficulty filter make that choice quick, even if you have never built a content plan.

How do I turn a cluster into published articles?

Select the keywords of a silo and send them to the Blog Content Planner, where each one becomes a slot in your calendar and keeps its priority. You can also generate the articles right away with the Blog Article Generator. With autopilot on, each planned article is written and published to your CMS on its day.

How does Sorank compete with billion-dollar tools like Semrush?

We don't. Sorank isn't trying to be another Semrush or Ahrefs. Those tools are built for data, Sorank is built to do the work. Instead of more dashboards to check, it turns SEO and GEO insights into actions: articles written and published, backlinks earned, technical fixes and AI visibility tracking. Less complexity, more results.

How much does Sorank cost?

From $49/month per website on a yearly plan, with a 3-day free trial and a 90-day money-back guarantee. Every plan includes articles, AI visibility tracking and access to the Backlink Network; higher plans add more articles, more AIs tracked and more backlink credits. No setup fees, no paying for seats you don't use.
