Frequently Asked Questions
Is Screaming Frog better than Semrush for site audits?
For deep technical crawling, yes. Screaming Frog offers more granular control and data than any cloud-based audit tool. But Semrush's site audit is easier to use and runs automatically on a schedule.
Do I need Screaming Frog if I have Semrush?
For basic site audits, Semrush's built-in tool is sufficient. If you do heavy technical SEO work (large sites, custom extraction, advanced crawl analysis), Screaming Frog is essential.
Is Screaming Frog free?
Screaming Frog offers a free version limited to 500 URLs per crawl. The paid version (£259/year) removes this limit and adds advanced features like JavaScript rendering, custom extraction, and scheduling.
