SEMrush Site Audit - Technical SEO Analysis with Auto-Cleanup

Run SEMrush Site Audits using your own API key. Automatically creates a project, runs a comprehensive technical SEO audit, extracts all issues, and optionally deletes the project to save your quota. Perfect for agencies and consultants who need one-off audits without using up project slots.

BYOK (Bring Your Own Key) -- you provide your own API credentials.

Troubleshooting

"API key is required"

You have Demo Mode turned off but didn't provide an API key. Either:

• Turn Demo Mode on to test with sample data
• Add your API key in the input

"API error 403" or "Unauthorized"

Your API key is invalid, expired, or doesn't have access to this specific API endpoint. Double-check your key and account permissions.

"API error 429" or "Rate limit"

Too many requests. Wait a minute and try again, or reduce the number of items per run.

No results or empty dataset

Check the run log for error messages. Common causes:

• Invalid input format (check the examples above)
• API key without proper permissions
• The target data doesn't exist or is too small to track

How do I test without an API key?

Enable Demo Mode in the input. This returns realistic sample data so you can verify the output format works for your workflow.
