Website Audit Cost and Pricing in 2026

Before diving into the DIY checklist, let's address the most common question: how much does a website audit cost?

Our recommendation: Start with a free automated audit (like our Website Audit Tool) to identify major issues. If the tool finds 20+ critical problems, invest in a professional audit. If it finds 5-10 issues, you can likely fix them yourself using this guide. Hidden costs to avoid:

• Some agencies charge $500 for audits that are just exports from free tools
• "One-time" audits are worthless without a plan to fix findings
• Cheap audits ($50-$100) typically miss technical issues that actually affect rankings

Frequently Asked Questions

What is a website audit?

A website audit is a comprehensive analysis of your site's health, performance, and search engine optimization. It checks technical factors (speed, mobile-friendliness, security), on-page SEO (titles, content, internal links), and user experience (navigation, design, conversions).

Website audit costs range from free (DIY tools) to $15,000+ (enterprise audits). Free automated tools handle 80% of what beginners need.

Can I do a website code audit myself?
