How do I measure SEO success?

Measure SEO success using multiple metrics: organic traffic (sessions from search), keyword rankings (positions for target keywords), conversions from organic traffic, click-through rates from search results, and domain authority. Use Google Search Console for search-specific data and Google Analytics for traffic and conversions. Track rankings using tools like Ahrefs or SEMrush. Monitor Core Web Vitals. Look at trends over time rather than daily fluctuations. Example: SEO success might be measured by 50% increase in organic traffic, moving from page 2 to page 1 for target keywords, and 30% increase in conversions from organic search over 6 months.
