SEO Agencies vs Surfer SEO, feature by feature
| Feature | SEO Agencies | Surfer SEO |
|---|---|---|
| Plans a full topical map before writing | Varies by agency — some offer strategy, not always a full topical map | No — optimizes individual pieces against competitors |

- Output is bounded by the agency's own writer capacity, not the size of the topical map
- Turnaround is usually measured in weeks per piece, not continuous publishing
