seo-ahrefs

Live Ahrefs data via the tested @ahrefs/mcp@0.0.11 server. Package check (2026-07-10): verify the current Ahrefs MCP package source before changing this tested version.

Prerequisites

• Run extensions/ahrefs/install.sh (Linux/macOS) or install.ps1 (Windows) before using this skill.
• An Ahrefs API token (https://ahrefs.com/api).
• Node 18+ on $PATH for the MCP server.

Before calling any Ahrefs tool, verify the MCP is connected by checking that any Ahrefs MCP tool is available in this session. If tools are not available, tell the user the extension is not installed and provide the install command above.

Routing

Command	Action
/seo ahrefs metrics <url>	Domain / URL rating, referring domain count, organic traffic estimate
/seo ahrefs backlinks <url>	Top referring domains, anchor distribution, follow/nofollow ratio
/seo ahrefs organic <url>	Organic keywords, ranking distribution, traffic by country
/seo ahrefs content <topic>	Content Explorer top results, social shares, referring domains

Output conventions

• Cite the data source on every metric: "Ahrefs (live, confidence 1.00)".
• When Ahrefs and Moz disagree on the same metric, trust Ahrefs and note the discrepancy in the report.
• Toxic link assessment: combine Ahrefs backlink quality signals with the existing seo-backlinks Common Crawl + verify crawler signals.

Cross-skill delegation

• For multi-source confidence weighting across Moz + Bing + Common Crawl + Ahrefs, hand back to seo-backlinks.
• For SERP-feature analysis where Ahrefs and DataForSEO overlap, prefer DataForSEO for live SERP data.

Cost guardrails

Ahrefs API usage is metered per unit. Before running a batch (>= 50 URLs):

1. Estimate cost with "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run dataforseo_costs.py (the cost-tracker module is generic and supports Ahrefs unit accounting).
2. Surface the estimate to the orchestrator.
3. Log actual cost after each call.

This is the same workflow the seo-dataforseo skill uses.
