How to Choose an SEO Agency
The most important factor in choosing an SEO agency is their commitment to sustainable, white-hat strategies. Ask directly about their link building practices—agencies that promise quick results through purchased links or private blog networks put your site at risk of Google penalties that can devastate organic traffic. Quality agencies build authority through genuine content, digital PR, and organic outreach.
Look for transparency in reporting and strategy. The best SEO agencies provide clear explanations of what they're doing and why, with regular reporting that shows progress toward specific ranking and traffic goals. Be wary of agencies that treat their methods as proprietary secrets or can't explain their approach in plain language.
Consider the technical depth of their team. Modern SEO requires expertise in site architecture, Core Web Vitals, structured data, and increasingly, AI-generated content strategy. Ask about their process for technical audits and how they collaborate with your development team to implement recommendations.
Budget expectations range widely based on competition level and scope. Local SEO for a single-location business might start at $1,500-$3,000/month, while national or enterprise SEO programs typically require $10,000-$25,000+ monthly investment. Timeline matters too—legitimate SEO takes 4-6 months to show meaningful results, so be skeptical of agencies promising first-page rankings within weeks.
Red Flags to Avoid
- Guaranteeing specific rankings or positions (no one can guarantee Google results)
- Unwilling to explain their methodology or techniques
- Using private blog networks or other manipulative link schemes
- Promising results in unrealistically short timeframes
- No clear reporting or communication process
- Previous clients have been penalized by Google
- Vague about what work is actually being performed
Questions to Ask
- Can you walk me through your technical SEO audit process?

- What tools do you use for research, tracking, and reporting?
- How long before we should expect to see meaningful results?
