Verdict
Choose Google Trends when
- Keyword research quality for SEO content matters to you. Supports directional topic discovery, but not an SEO keyword database or prioritization workflow.
- Measurement & tracking matters to you. Tracks aggregate search interest over time, not a site's rankings or content performance.
- Value accessibility matters to you. Very accessible public product surface with broad geography and learning materials.
- Free tools matters to you. The core official site is publicly usable and presents no paid plan or paywall in the fetched page.
Verdict
Choose Hunter when
- Estimated customer scale matters to you. Large first-party adoption claim, though it is a user count rather than a customer-account count.
- Agent readiness level matters to you. Good practical agent access through REST APIs and a remote MCP server with documented actions.
- Ease of use and autonomous level matters to you. Sequences automate sending/follow-ups and MCP can execute workflows, but human review and mailbox setup remain part of the workflow.
