If you run an SEO or GEO agency with 10–200 client brands, your tool requirements are different from a single-brand VP's. You optimize for throughput, white-label trust, and batch operations — not for the depth of any single dashboard.
The 4 features that actually decide agency tool fit
1. Portfolio view (red/yellow/green across all clients)
Monday-morning use case: open the tool, see 12 client brands grouped by attention severity in one screen, click into the worst-trending one. Most single-brand AI visibility tools force a per-site picker (Ahrefs AI Search) or per-tenant context switch — both burn 30 seconds per client every morning.
Arenza's /portfolio page lays out all owned brands in a red (≥10 wrong claims) / yellow (≥3) / green (<3) grid with 7-day trend per card. Click → brand-internal sidebar.
2. White-label reports
When you forward a weekly digest to a client VP, that VP cares about your agency, not the tool vendor. Reports/PDFs/scheduled emails must carry your logo and your agency name. This is the single biggest differentiator — without it, ~70% of agency prospects walk.
Arenza ships per-brand white-label settings (logo upload, accent color, public display name) through its agency partnership — sales-led, built for brand portfolios. Profound puts white-label in Enterprise. Ahrefs AI Search and Peec.ai don't publish it at all.
3. Bulk operations
Onboarding 10 client brands one-by-one is a 30-minute tax. CSV bulk import + "copy prompts/competitors from brand A to brand B" cuts that to under 5 minutes.
- Arenza: /portfolio/bulk-import accepts CSV (Sheets export works), client-side validates, single submit. /portfolio/copy-settings copies prompt sets and competitor lists across multiple brands in one operation.
- Ahrefs AI Search: no bulk import; each site is a separate workspace.
- Profound: bulk import via CSM, not self-serve.
4. MCP server and public API
Modern agencies live in their own ops stack — Notion dashboards for clients, Slack/Feishu for internal alerts, Linear for delivery. The GEO tool has to push and pull data; otherwise it becomes a tab nobody opens.
- Arenza: hosted MCP server at mcp.arenza.ai (read-only tools: list_brands, get_brand_overview, list_prompts, get_brand_corrections, plus deterministic GEO tools score_geo_article / audit_site), public REST API, per-brand Slack/Feishu/webhook channels.
- Ahrefs AI Search: no MCP, no public API as of May 2026.
- Profound: REST API on Enterprise tier.
- Peec.ai: no MCP, no API.

Pricing for agencies
Agencies run on a sales-led partnership: one multi-brand workspace, white-label reports, bulk CSV import, and a dedicated contact — terms agreed per contract (hello@arenza.ai or https://arenza.ai/agencies). For scale reference, a pure tracker like Peec runs $1900/mo for 20 brands, with white-label not published and nothing executed. Self-serve pricing (Free $0 to see where a brand stands; Starter $49/mo to compare with unlimited tracked competitors and publish 5 articles a month; Pro $299/mo for the full product) is at https://arenza.ai/pricing.
