1. What is a Live Website SEO Audit?
A live SEO audit assesses both front-facing content and backend technical code. Standards maintained by Google Search Central look beyond simple keywords, evaluating mobile friendliness, security certificates (HTTPS), indexability, and clean document structure.
2. The 4 Pillars of Google Lighthouse Scoring
- Google SEO: Checks whether your title tags, meta descriptions, alt attributes, and canonical tags meet standard search crawler protocols.
- Performance (Speed): Measures server response time, render-blocking resources, image compression, and time-to-interactive on mobile devices.
- Accessibility: Ensures buttons, color contrasts, screen readers, and navigation elements are accessible to all internet users.
- Best Practices: Scans for modern HTTPS security, JavaScript vulnerabilities, and proper doctype configurations.
3. Why Page Speed Directly Impacts Search Rankings
Google uses Core Web Vitals as official ranking signals. Slow-loading websites experience high bounce rates and lower conversions. Optimizing JavaScript execution, deferring unused CSS, and serving WebP image formats are vital steps to achieving a 90+ performance score.
4. Frequently Asked Questions (FAQs)
What is a good Google SEO score?
A score of 85 to 100 is considered green (passed), meaning search engine bots can easily index and understand your page contents.
Why does the mobile score differ from desktop?
Mobile devices have slower processors and utilize cellular network bandwidth, making mobile performance optimization stricter under Google’s mobile-first indexing.
