KNOWLEDGE BASE
Frequently Asked Questions
Everything you need to know about SEO audits, Core Web Vitals, and improving your rankings.
Is this SEO audit tool really free?
▼
Yes, 100%. We believe professional-grade technical SEO data should be accessible to everyone. There are no limits on scans or PDF downloads.
How accurate is the Lighthouse data?
▼
Extremely accurate. We use the official Google PageSpeed Insights API, which runs a headless Chrome instance to audit your site exactly as Google does.
Does the audit affect my site performance?
▼
No. The audit is performed by Google's servers. It's similar to a single user visiting your page, so there's no impact on your server load.
What is the most important SEO metric?
▼
While all metrics matter, Core Web Vitals (LCP, CLS, INP) are now direct ranking factors. If you fail these, Google will actively suppress your rankings.
How often should I audit my website?
▼
We recommend a full technical audit once a month, or immediately after any major code change, CMS update, or content migration.
Can AI really fix my SEO issues?
▼
AI provides the logic and the code snippets, but you (or your developer) must implement them. Gemini AI makes the "how-to" much easier to understand.
Why is my mobile score lower than desktop?
▼
Mobile devices have slower processors and often use 4G/5G connections. Google audits mobile-first, so this is the score that matters most for rankings.
Does this tool check for backlinks?
▼
This version focuses on technical SEO and performance. For backlink auditing, we recommend using our upcoming Link Intelligence tool.
What is INP (Interaction to Next Paint)?
▼
INP is Google's newest Core Web Vital. It measures how quickly your site responds to user interactions like clicks and taps. It's a critical ranking factor in 2026.
Can I use the PDF report for clients?
▼
Absolutely. The report is designed to be professional and easy to understand, making it perfect for agencies to share with their clients.
