Frequently Asked Questions
Can Surfer SEO replace a website audit?
No. Surfer optimizes content for target keywords but doesn't check technical SEO (broken links, schema, CWV), AI visibility (AEO/GEO), or compliance. A website can have perfect Surfer scores but still rank poorly due to technical issues only SAGIScan catches.
Should I use SAGIScan or Surfer first?
SAGIScan first. Fix your technical foundation (site speed, schema, crawlability, AI readiness) before optimizing individual content pieces. A technically broken site won't rank well no matter how perfectly your content is optimized for keywords.
Does SAGIScan help with content creation?
SAGIScan's AI Content Analyzer evaluates existing content quality (E-E-A-T, readability, AI citation readiness) and suggests improvements. However, it doesn't provide keyword-specific content guidelines like Surfer does. Use SAGIScan for content quality, Surfer for keyword targeting.
