Free semantic core clustering

The KeyClusterer program is designed to group the semantic core using the Hard and Soft methods. Besides clustering, KeyClusterer is also equipped with a feature of manual phrase grouping, which became available after auto clustering of search queries.

Key Features

  • Grouping an arbitrary list of keywords using the Hard and Soft methods
  • Automatic grouping of search keywords with "manual" specification of the grouping accuracy (from 1 to 10 points)
  • "Manual" semantic core grouping, creation of arbitrary folders and groups
  • Checking positions on search keywords and determining the relevant landing pages
  • Importing SERP data from Google, Bing and Yandex for grouping phrases offline
  • Exporting clustering to Excel (CSV)

Differences From Analogues

  • Clustering semantic cores of almost any size
  • High clustering speed, fast switching between projects
  • Portable format
  • Freeware

Data for keywods grouping is collected from Google search results and is processed using SERPRiver. After clustering, the manual query grouping becomes available (shifting queries by groups, creating new groups and deleting clusters). The clustering query results are exported to an CSV file (Excel).

The program can import search results from Google and Bing SERP data to group phrases offline (see example of an import file in the archive).
