Common SEO Agency Mistakes
- Guaranteeing rankings: Never guarantee #1 rankings. SEO is unpredictable.
- Underpricing: $200/month doesn't cover your time. Charge $500+ minimum.
- No reporting: Clients need to see progress. Send monthly reports.
- Ignoring technical SEO: On-page isn't enough. Fix technical issues too.
- No contract: Use 6-month minimum contracts. SEO takes time.

SEO Agency Growth Tips
Niche down: Instead of offering general SEO, specialize in an industry (e-commerce SEO, local SEO for restaurants, SaaS SEO). Specialized agencies charge 30-50% more.
Build case studies: Document before/after results for every client. Case studies are your best sales tool. Use Canva Free ($0) to create visual case study decks.
