SEO Algorithm Keyword Clustering
What it is
SEO Algorithm Keyword Clustering groups keyword lists by word stems, AI semantic understanding, or overlap among Google search results. Upload CSV or TXT files, including Keyword,Volume data, then edit the generated groups by dragging keywords, merging or splitting clusters, or creating new ones. Stem clustering groups roots and is free for up to 200 keywords. AI Semantic considers synonyms, context, and changes in intent that stemming can miss. SERP-based clustering fetches Google’s live top-10 results for every keyword and groups terms sharing URLs; those results are not cached. You can choose a Google region or enter a city, region, and country, then set Loose, Normal, or Tight strictness. Results offer Commercial, Informational, Transactional, Navigational, and Local intent filters and sorting by size, name, intent, or volume. Exports include CSV, XLSX, and Google Sheets. The Stems plan costs nothing; SERP-based PRO uses 2 credits per keyword, and AI Semantic uses 12 credits per 1,000 keywords, with prices not listed.
