Additional Value: €480,000/year
ROI: 1,900%

Red Flags: When to Be Skeptical

🚩 Guaranteed rankings: No one can guarantee rankings
🚩 Very low prices: Under €500/month = questionable methods
🚩 Quick results promised: Serious SEO takes 3-6 months
🚩 No transparency: No reports = no control
🚩 Black-hat methods: Can lead to Google penalties

How to Find the Right SEO Agency

  1. Check case studies: Real results with verifiable data
  2. Get references: Talk to current clients
  3. Ask about strategy: How do they plan to proceed?
  4. Understand reporting: Which KPIs are measured?
  5. Contract terms: Duration, notice periods, services

Conclusion

SEO is an investment, not a cost. The question isn't whether, but how much and with whom. Choose an agency that understands your business goals and communicates transparently.
