What to evaluate before choosing

For a support operations manager, prioritize:

• Search quality: keyword search, synonym handling, suggested articles
• SEO: public indexing, metadata, URL control
• Analytics: deflection, top searches, no-result queries, article usefulness
• Workflow: drafts, approvals, version control, review reminders
• Branding/customization: domain, theme, layout
• Integrations: ticketing, chat, CRM, product analytics
• Multilingual support
• Access control: public vs internal content
• Maintenance burden: how easy it is for agents to keep content current
