SEO Agencies vs Writesonic, feature by feature
| Feature | SEO Agencies | Writesonic |
|---|---|---|
| Plans a full topical map before writing | Varies by agency — some offer strategy, not always a full topical map | No — generates individual pieces on request |

| Auto-interlinks pages as the site grows | Varies — depends on whether the agency manages it manually | No automatic interlinking |
| Hosts the content on your domain | No — agencies typically publish into your existing site/CMS | No — publishes through your own CMS |
| Machine files for AI + search (llms.txt, JSON-LD, sitemaps — 25+) | Rarely — not a standard agency deliverable | No |
| Pricing model | Retainer-based, commonly $1,500–$10,000+/mo depending on scope | Credit-based plans |
Where SEO Agencies falls short

- 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
Where Writesonic falls short

- No hosting — output publishes through your own CMS
- No automatic interlinking between generated pages
