Install

Install the verified ClawLink plugin from ClawHub. After the user confirms, complete the full setup so ClawLink tools are visible in the next OpenClaw chat.

openclaw plugins install clawhub:clawlink-plugin
openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart

Then tell the user: "OpenClaw has been restarted. Send /new as a standalone message to start a fresh chat, then ask for Semrush again."

Quick Start

# Check account API units balance
clawlink_call_tool --tool "semrush_account_units_balance"

# Get keyword overview for a phrase
clawlink_call_tool --tool "semrush_keyword_overview_one_database" --params '{"phrase": "content marketing", "database": "us"}'

# Get backlinks overview for a domain
clawlink_call_tool --tool "semrush_backlinks_overview" --params '{"target": "example.com"}'

Authentication

All Semrush tool calls are authenticated automatically by ClawLink using your Semrush API key stored securely in the dashboard.

No API key is required in chat. ClawLink injects your API key into every Semrush API request on your behalf.

Getting Connected

Install the ClawLink plugin (see Install above).
Pair the plugin with clawlink_begin_pairing if it is not configured yet.
Open https://claw-link.dev/dashboard?add=semrush and connect Semrush with your API key.
Call clawlink_list_integrations to verify the connection is active.

Connection Management

List Connections

clawlink_list_integrations

Response: Returns all connected integrations. Look for semrush in the list.

Verify Connection

clawlink_list_tools --integration semrush

Response: Returns the live tool catalog for Semrush.

Reconnect

If Semrush tools are missing or the connection shows an error:

Direct the user to https://claw-link.dev/dashboard?add=semrush
After they confirm, call clawlink_list_integrations to verify
Then call clawlink_list_tools --integration semrush

Security & Permissions

Access is scoped to the Semrush account associated with the connected API key.
All operations are read-only — Semrush tools do not modify any data in your Semrush account.
API units are consumed per request — monitor semrush_account_units_balance before launching large batches.
Responses are CSV-like strings (not JSON) — parse with delimiter-aware splitting before structured use.

Compare multiple domains

clawlink_call_tool --tool "semrush_domain_vs_domain" \
  --params '{"domains": "site1.com,site2.com,site3.com", "database": "us"}'

Discovery Workflow

Call clawlink_list_integrations to confirm Semrush is connected.
Call clawlink_list_tools --integration semrush to see the live catalog.
Treat the returned list as the source of truth. Do not guess or assume what tools exist.
If the user describes a capability but the exact tool is unclear, call clawlink_search_tools with a short query and integration semrush.
If no Semrush tools appear, direct the user to https://claw-link.dev/dashboard?add=semrush.

Execution Workflow

┌─────────────────────────────────────────────────────────────┐
│  SEMRUSH OPERATIONS (All Read-Only)                         │
│  list → get → describe → call                                │
│                                                             │
│  Example: Check units → Get keyword overview → Parse results │
└─────────────────────────────────────────────────────────────┘

For unfamiliar tools or ambiguous requests, call clawlink_describe_tool first.
Use the returned guidance, schema, whenToUse, askBefore, safeDefaults, examples, and followups to shape the call.
All Semrush tools are read-only — no confirmation is required for data retrieval.
Parse CSV-formatted responses before structured use. Use sep=';' and cast numeric columns before aggregation.
A response of ERROR 50 :: NOTHING FOUND is a valid zero-result — not a system error.
If the tool call fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

Notes

All Semrush tools are read-only — no write or destructive operations exist in this skill.
Responses are CSV-like text strings (not JSON) — parse by splitting on newlines and delimiters before extracting structured rows.
The literal response ERROR 50 :: NOTHING FOUND means zero results for that domain/keyword in the selected database — treat as a valid zero-result, not an error.
Traffic metrics (e.g., Tr) are modeled estimates — incompatible with first-party analytics data.
API units are consumed per request — preflight with semrush_account_units_balance before launching large batches.
display_date for historical data must be in 'YYYYMM15' format (day must be '15').
display_limit must surpass display_offset when pagination is used.

Error Handling

Status / Error	Meaning
Tool not found	The tool name does not exist in the current catalog. Verify with `clawlink_list_tools --integration semrush`.
Missing connection	Semrush is not connected. Direct the user to https://claw-link.dev/dashboard?add=semrush.
`ERROR 50 :: NOTHING FOUND`	Zero results for the target in the selected database — treat as a valid empty response.
`Insufficient units`	API units exhausted — check `semrush_account_units_balance` and wait for replenishment.
`Invalid database`	The specified regional database is not supported. Check available databases in the tool schema.

Troubleshooting: Tools Not Visible

Check that the ClawLink plugin is installed:
```
openclaw plugins list
```
If the plugin is installed but tools are missing, tell the user to send /new as a standalone message to reload the catalog.

If a fresh chat does not help, run:

openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart

After restart, tell the user to send /new again and retry.

Troubleshooting: Parsing CSV Responses

All Semrush responses are CSV-like strings — use delimiter splitting (semicolon ; for most tools) to parse rows.
Cast numeric columns (backlinks_num, domain_ascore, etc.) before aggregation.
Headers match export_columns codes (e.g., 'Ph', 'Nq', 'Kd') — parse headers into a structured table first.
Use sep=';' when calling tools that support the display_separate parameter.
