Geo-based redirects are a common technique used to route users to regional content (for example, redirecting / to /us/ or /ca/).
In Adobe Experience Manager as a Cloud Service (AEMaaCS), these redirects are often implemented at the CDN layer, before requests reach Dispatcher or Publish.
While technically effective, this approach can introduce unintended SEO side effects if not carefully designed.
Why this matters
Search engine crawlers do not behave like end users:
Crawling locations are limited and inconsistent
Geo signals may not reflect real user geography
CDN-level redirects can be applied uniformly to both bots and users
When geo-based redirects are enforced unconditionally at the edge, crawlers may:
Index an incorrect locale
Fail to discover alternative regions
Encounter redirect chains that reduce crawl efficiency
These issues often appear without visible errors in AEM logs or monitoring tools.
AEMaaCS-specific considerations
In AEMaaCS, the mandatory CDN layer plays a critical role in request handling:
Redirects occur before Dispatcher rules
Bot and human traffic is treated identically unless explicitly separated
SEO behavior is determined by edge logic, not only application configuration
As a result, geo-based redirects should be evaluated from an architecture and SEO perspective, not only as a localization feature.
