Quick answer

Keyword grouping (keyword clustering) organises a long keyword list into topics so each group can be targeted by one page. Paste your keywords into Raw Keyword List, add root words such as “grinder”, “espresso” and “cold brew” to Seed Terms, and every keyword containing a seed is labelled with that cluster; the rest are marked UNGROUPED. With Excel/Sheets Format ticked, the result pastes into a spreadsheet as two columns: Keyword and Cluster.

Keyword exports from Semrush, Ahrefs, Google Keyword Planner or Search Console often contain hundreds or thousands of phrases. Sorting them by hand into pages and topics is the slowest part of planning a content strategy.

This keyword grouping tool clusters by the seed terms you set, so you control the topics. It is ideal for building topical maps, deciding which keywords belong on one page and spotting gaps that need new content.

Example: Clustering a Coffee Keyword List

Nine keywords with the seeds grinder, espresso and cold brew give this result, with 8 of 9 keywords grouped:

KeywordCluster
best coffee grinderGRINDER
burr coffee grinderGRINDER

how to clean a coffee grinderGRINDER
espresso machine under 500ESPRESSO
best espresso machine for homeESPRESSO
how to make cold brewCOLD BREW
cold brew ratioCOLD BREW
french press vs pour overUNGROUPED

“coffee grinder for espresso” contains two seeds and goes to GRINDER because that seed is listed first. Put your most specific or most important seeds at the top of the list to control which cluster wins.

How to Use the Keyword Grouping Tool

Step 1: Paste Keywords and Add Seed Terms

Paste your keyword export into Raw Keyword List, one keyword per line. In Seed Terms (Categories), enter the root words for each topic, one per line. The badges show how many keywords and seeds were read, and the clusters update as you type.

Step 1 paste a raw keyword list and enter seed terms in the keyword grouping tool

Step 2: Review and Copy the Clusters

The Structured Cluster Output lists each keyword with its cluster, and the status bar shows how many keywords were grouped. Keep Excel/Sheets Format ticked for a two-column sheet, or untick it for a grouped text list. Click Copy Clustered Sheet and paste it into your spreadsheet.

Step 2 review keyword clusters and copy the clustered sheet for Excel or Google Sheets

Choosing Good Seed Terms

  • Use product or topic roots: “grinder”, “espresso”, “refinance”, “keto”.
  • Add intent seeds: “how to”, “best”, “vs”, “near me” or “price” separate informational, commercial and local searches.
  • Order matters: a keyword joins the first matching seed, so place narrow seeds above broad ones.
  • Review UNGROUPED: it often reveals a topic you forgot, so add a new seed and run it again.

From Clusters to a Content Plan

  1. Give each main cluster one pillar or category page.
  2. Split large clusters by intent: guides for “how to”, comparison posts for “vs”, buying guides for “best”.
  3. Use the other keywords in a cluster as H2s, H3s and FAQs on that page instead of separate thin posts.
  4. Link cluster pages to each other and to the pillar page to build topical authority.

Seed Clustering vs SERP Clustering

MethodHow it groupsBest for
Seed-based (this tool)Keywords that contain the same root wordFast topical maps and site structure
SERP-basedKeywords whose Google results share the same URLsDeciding exactly which keywords share one page

Seed grouping is quick and free; for close calls, search the two keywords and check whether Google shows the same pages before merging them. “LSI keywords” is a common SEO name for related terms; Google does not use latent semantic indexing, but grouping related phrases still helps you cover a topic fully.
