Run comprehensive SEMrush Site Audits using your own API key (BYOK). The killer feature? Automatically delete the project after extracting results to save your precious project quota!

The Problem This Solves

SEMrush limits the number of projects you can have based on your plan:

• Pro: 5 projects
• Guru: 15 projects
• Business: 40 projects

If you're an agency or consultant running audits for multiple clients, you quickly run out of project slots. This actor:

1. Creates a temporary project
2. Runs a full site audit
3. Extracts all issues and health score
4. Deletes the project automatically
5. Returns your project slot for the next client!

Features

Technical SEO Analysis

• Health Score: Overall site health (0-100)
• Errors: Critical issues (5xx, 4xx, broken links, mixed content)
• Warnings: Important issues (missing meta, slow pages, redirect chains)
• Notices: Minor issues (multiple H1s, thin content)

Smart Automation

• Auto-Cleanup: Delete project after audit to save quota
• Existing Projects: Use an existing project instead of creating new
• Wait or Fire-and-Forget: Wait for completion or return immediately
• Configurable Crawl: Set page limits and subdomain options

Integration Ready

• Webhook Support: Zapier, Make, n8n, or custom endpoints
• Structured Output: Clean JSON for automation workflows
• API Units Tracking: Know how many SEMrush units you used
