FAQ

What is a website performance audit and why do I need one?▼

A website performance audit analyzes your site’s speed, SEO, security, and user experience. It identifies issues hurting your Google rankings, conversion rates, and user engagement. Our thermal scan checks 15+ categories including Core Web Vitals, technical SEO, accessibility, and security vulnerabilities.

How does RoastWeb’s site speed test work?▼

Paste your URL → Click "Roast My Site" → Get results in 10 seconds. We use Google PageSpeed Insights API (Lighthouse), analyze Core Web Vitals (LCP, INP, CLS), run 15+ custom security and SEO checks, then provide AI-powered fix suggestions with code snippets.

Is RoastWeb really free? What are the limits?▼

YES - completely free with 3 scans/day. No credit card, no signup required. You get full analysis reports, shareable links, and basic fixes. Pro plan ($29/mo) unlocks unlimited scans, AI Deep Analysis, PDF exports, API access, and priority scanning.

How accurate are your Core Web Vitals measurements?▼

We use Google’s official Lighthouse API - the same technology behind PageSpeed Insights. Our Core Web Vitals data (LCP, INP, CLS) comes from real Chrome user experiences (CrUX dataset). This is the exact data Google uses for search ranking.

What’s the difference between RoastWeb and Google PageSpeed Insights?▼

PageSpeed only shows problems. RoastWeb shows problems + AI-powered solutions with code snippets. We also add 10+ checks PageSpeed doesn’t have: SEO meta tags, accessibility issues, security headers, mobile optimization, image analysis, and more. Plus you get shareable reports and embeddable badges.

Can I use RoastWeb for client reports and agency work?▼

Absolutely! Pro plan includes PDF exports perfect for client presentations. Agency plan ($99/mo) adds white-label reports, custom branding, batch scanning for multiple sites, competitor analysis, unlimited team members, and priority support.

Do you store my website data or scan results?▼

We store scan results for 30 days so you can share links and track improvements. Your website data is encrypted and never shared with third parties. We’re SOC 2 compliant. You can delete reports anytime from your dashboard. Free scans are public; Pro scans can be private.

How often should I run website performance audits?▼

Run audits after every major deployment, code change, or content update. Pro users typically scan weekly to monitor Core Web Vitals trends. Use our API to integrate scans into your CI/CD pipeline for automatic testing before production deploys.

What technical SEO issues can RoastWeb detect?▼

We check meta titles/descriptions, heading structure, canonical tags, robots.txt, sitemap.xml, structured data (schema.org), Open Graph tags, Twitter Cards, mobile-friendliness, HTTPS implementation, security headers, page load speed, and 50+ other ranking factors.

Can I integrate RoastWeb into my development workflow?▼

Yes! Pro plan includes REST API access. Integrate scans into GitHub Actions, GitLab CI, Jenkins, or any CI/CD pipeline. Auto-scan on pull requests, block deployments if performance drops below thresholds, and track metrics over time in custom dashboards.
