• Recoverable traffic × Conversion rate × Average order value = Monthly revenue impact

Time-to-value comparison:

• Relixir: Under 30 days to ranking improvements

• Industry average: 60-90 days for traditional SEO improvements

• Faster implementation = Earlier revenue recovery and competitive advantage

Platform coverage value:

• ChatGPT maintains approximately 59.7% AI search market share with 3.8 billion monthly visits (Relixir)
