Adobe Experience Manager Benchmarks

Large enterprises with multiple brands, regions, and teams that need governance, integrations, and complex content operations.

An enterprise marketing website.

• AEM sites represent the largest organizations in our corpus. Content governance is typically strong -- consistent metadata, well-structured navigation, and intentional internal linking.
• When AEM sites perform well, it's because a team made deliberate, expensive decisions to make them perform. The platform doesn't optimize by default.
• Brand consistency is a genuine AEM strength. We rarely see the kind of rogue page content or inconsistent metadata that appears on decentralized CMS installs.

• Slow LCP despite enterprise infrastructure. Heavy DAM-served images without lazy loading are the most common culprit.
• Personalization systems that create indexability challenges. Content that changes based on visitor context is content Google can't consistently read.
• Third-party analytics and tag management that loads synchronously. AEM sites average the highest third-party script count we see.

• AEM sites have the highest third-party script count in our corpus -- consistently above 20, which is our flagging threshold. More enterprise stakeholders means more tracking, compliance, and analytics requirements on every page.
• AEM sites show the most consistent brand application across pages in our corpus. Navigation, footer, metadata -- everything is enforced at the platform level, and the consistency shows in the benchmark data.
