Turn a messy keyword list into intent-based content clusters

Act as an SEO information architect. Site context: we sell CRM software aimed at small teams under 20 people

Raw keyword list:
best crm for small business (2400)
crm software comparison (1900)
free crm for startups (1600)
crm pricing (880)
how to choose a crm (720)

1. Group these into distinct content clusters, where a cluster means keywords one single page could realistically satisfy without cannibalizing another page on the same site. Use search intent as the primary grouping signal, not shared words — "crm pricing" and "crm software comparison" look similar but serve different intents and should NOT be forced into one cluster unless you can justify it.
2. Name each cluster with the page title it implies — outcome-first, not just the seed keyword.
3. For each cluster, state the dominant intent (informational / commercial-investigation / transactional) and the single keyword that should be the page's primary target. The rest become secondary targets the page ranks for through topical depth, not separate H1s.
4. Flag cannibalization risks: any two keywords in my list that look like they'd want the same page, where I should pick one primary target and fold the other in rather than building two competing pages.
5. Flag anything you can't confidently cluster — ambiguous keywords where intent depends on the searcher's stage — and tell me what additional context would resolve it.
6. Suggest the pillar-cluster hierarchy: if any clusters are naturally subtopics of a broader pillar page, name the pillar.

Output as a table: Cluster name | Primary keyword | Secondary keywords | Intent | Suggested page type.
