Link Building Software for Scaling Agencies
CitationBench runs end-to-end link building campaigns across your entire client portfolio, from competitor SERP analysis to 50 personalized outreach drafts with human approval gates.
Most Link Building Tools Break at Scale
Fragmented tools and manual steps slow campaigns, expose clients to compliance risk, and kill agency margins.
Outreach dies in spreadsheets
Teams track link prospects in Google Sheets, losing reply context and letting warm relationships go cold.
No audit trail for clients
Sending outreach without approval gates means one rogue email can damage a client relationship permanently.
Tools don't talk to each other
Apollo, Instantly, Ahrefs, and your CRM each live in a separate tab, doubling manual work per campaign.
The fix
One Platform. Full Link Building Ops.
CitationBench connects competitor backlink research, Apollo-powered contact discovery, Instantly email outreach, and a relationship CRM into one agentic workflow. Human approval gates keep every campaign compliant before a single email is sent.
Every Tool Your Link Building Campaigns Need
From competitor backlink analysis to outreach drafting, relationship tracking, and campaign-level reporting across all client workspaces.
Outreach Automation
One Keyword to 50 Outreach Drafts
Enter one keyword and CitationBench scrapes the SERP, discovers contacts via Apollo, and generates 50 personalized outreach drafts via Instantly in a single POST /v1/link-building/serp-outreach call. Bulk-approve before sending.
- SERP to draft in one call
- Apollo contact discovery built in
- Bulk approve before sending

Compliance and Control

- Full audit log per campaign

How it works
From sign-up to first call in five minutes.
Sign up and get your key
An `sk_test_*` key lands in your dashboard instantly. No demo gate — start calling real endpoints with shape-complete responses.
Add the MCP server or hit REST
`claude mcp add citationbench https://mcp.citationbench.com/mcp` from Claude Code, Cursor, or any MCP client. Or `curl` against `api.citationbench.com/v1/*` directly.
Run a tool or invoke an agent
Every tool returns shape-complete demo data without auth, so your agent works before the user signs up. Tools across research, production, indexing, link-building, and agents.
Scope to a workspace and ship
Add `X-Workspace-Id: ws_***` to scope per client. Switch to a live `sk_live_*` key when you're ready. Same API surface, same SDK.
Why CitationBench
Built for production, agency-scale, and AI-agent-first.
~35 tools, one MCP server
Hosted at mcp.citationbench.com/mcp. Works with Claude Code, Cursor, Claude Desktop, Windsurf, and ChatGPT Apps. No self-hosting required.
Durable jobs, not fire-and-forget
Every long-running call runs on Cyclonic workers — survives restarts, cancellable, resumable, streams via SSE. Production-safe by default.
Multi-workspace from day one
One master API key, N client workspaces. Switch with a single `X-Workspace-Id` header. Per-client data isolation, bulk ops across all of them.
Demo mode out of the box
Every endpoint responds in shape-complete demo mode without auth, so you can build the agent before the user signs up.
