Apify Scheduled Runs

Schedule weekly or monthly performance audits.

FAQ

Q: What's the difference between PageSpeed Insights and Lighthouse?

A: PageSpeed Insights includes real-user data (CrUX) showing how actual visitors experience your site. Lighthouse is a lab test showing potential performance. Both are valuable.

Q: Why do I need a Google API key?

A: The API key is optional but provides higher rate limits. Without it, you're limited to a few requests per minute.

Q: How are AI recommendations different?

A: AI recommendations are tailored to your detected tech stack. Instead of generic advice, you get WordPress-specific, React-specific, or Shopify-specific optimization steps.

Q: What if there's no CrUX data?

A: Sites with low traffic may not have CrUX data. The actor will still return Lighthouse lab data, just without real-user metrics.

Q: How often should I run audits?

A: After any significant changes, and at least monthly for ongoing monitoring. Core Web Vitals data updates every 28 days.

Common Problems & Solutions

"No field data available"

• Site may not have enough traffic for CrUX
• Lighthouse lab data is still returned
• Check Google Search Console for CrUX data

"Slow analysis"

• Multi-URL batches take longer
• Lighthouse tests are thorough and take 10-30 seconds each
• Use single URL for quick checks

"AI recommendations generic"

• Ensure includeTechStack: true for stack-specific advice
• Provide anthropicApiKey for AI features

"Demo data showing"

• Set demoMode: false
• For full features, provide anthropicApiKey
