Keyword Cluster Builder

Step-by-step guide

1. 1
   Paste your keyword list
   Enter your keywords in the textarea, one keyword per line. You can paste from a spreadsheet, keyword research tool export, or any list you've compiled. There is no minimum: even 5 keywords will produce useful clusters.
2. 2
   Set the keywords-per-cluster limit
   Use the number input to control how many keywords can belong to a single cluster (between 2 and 10). A lower number creates tighter, more focused clusters; a higher number groups more broadly. The default of 5 works well for most keyword sets.
3. 3
   Click 'Cluster Keywords'
   The tool groups your keywords by shared first meaningful words, ignoring stop words like 'how', 'the', 'to', and 'a'. Each cluster is automatically assigned a pillar topic (the shortest, broadest keyword in the group), search intent, and a suggested content type.
4. 4
   Review your clusters
   Each cluster appears as an expandable card showing the pillar topic, intent badge (Informational, Transactional, Commercial, or Navigational), supporting keywords, and content type recommendation. Click any card header to expand or collapse it.
5. 5
   Export as CSV
   Click 'Copy as CSV' to copy all clusters to your clipboard in comma-separated format, ready to paste into Google Sheets, Airtable, or your content planning tool. Each row contains the pillar, intent, all keywords in the cluster, and the suggested content type.

Frequently Asked Questions

What is topical SEO clustering and why does it matter?

Topical SEO clustering is the practice of grouping related keywords around a central topic so that you can build content that demonstrates comprehensive expertise on a subject. Search engines like Google reward sites that cover topics in depth with multiple interlinked pieces of content. A keyword cluster typically has one pillar page targeting the broadest head term and several supporting pages targeting more specific long-tail variations. This structure signals topical authority and helps your pages rank for a wider range of queries.

How does the clustering algorithm work?

The tool uses a rule-based string-matching approach. For each keyword, it identifies the first two meaningful words (ignoring common stop words like 'how', 'the', 'best', 'to'). Keywords sharing the same two-word prefix are placed in the same cluster. If no two-word match exists, the tool falls back to matching on the first meaningful word. Within each cluster, the shortest keyword is designated the pillar (head term), and longer variations become supporting keywords.

How is search intent detected?

Intent is classified by scanning the keywords in each cluster against predefined word lists. Keywords containing terms like 'login', 'sign in', or '.com' are classified as Navigational. Terms like 'buy', 'price', 'discount', or 'hire' signal Transactional intent. Terms like 'best', 'review', 'vs', or 'compare' indicate Commercial Investigation. All other clusters default to Informational. The classification is based on the full set of keywords in the cluster, not just the pillar.

What content type does the tool recommend and how?

Content type recommendations are derived from a combination of the detected intent and the pillar keyword text. Transactional and Navigational clusters get Landing Page recommendations since the user is close to taking action. Commercial Investigation clusters get Comparison pages to match the research-mode intent. Within Informational clusters, keywords containing words like 'guide' or 'tutorial' get Guide recommendations; those with 'what', 'why', or 'faq' get FAQ recommendations; and everything else defaults to Blog Post.

Can I use this tool for local SEO keyword clustering?

Yes. The tool works with any keyword list, including location-modified keywords like 'plumber in Dubai' or 'best coffee shop London'. Location terms do not interfere with the clustering logic because they are typically appended to the main topic phrase. A cluster like 'plumber Dubai', 'emergency plumber Dubai', and 'affordable plumber Dubai' would group together under the pillar 'plumber Dubai' with Transactional intent and a Landing Page recommendation: which is exactly right for local service pages.
