What to look for in a international seo agency

  • • Demonstrated work in your exact industry — ask for two case studies in your vertical before signing.
  • • Clear deliverables and cadence — how often reporting arrives, who is the named owner, and what is actually produced each month.
  • • Reasonable contract length — 3–6 months is typical; month-to-month or 12-month lock-ins are both worth questioning.
  • • Named strategists — avoid the bait-and-switch where your senior rep disappears after kickoff.
  • • A pricing model that matches your stage — the international seo retainer for a $1M ARR SaaS should not match a $100M ARR brand.
