Multisite Management in AEM sounds fancy until a rollout splashes across twenty locales and breaks three markets before lunch. With AEM 6.1 fresh on our servers and Touch UI getting real use, the temptation is to stamp out sites first and sort out the tree later. That path is fast for a week and slow for a year. The win comes from one simple idea. Structure before scale.
Problem framing
Teams push new markets, new campaigns, and product lines at different speeds. AEM gives us MSM, blueprints, live copies, language copies, rollout configs, and translation projects. Plenty of power. The trap is building a giant tree without shared rules. You end up with mixed language roots, templates that drift per market, and rollout storms that overwrite local edits. The CMS takes the blame when the real issue is a missing skeleton.
What we need is a clear content map, one way to push changes, and a short list of allowed local breaks. Set that early and authors stop fighting the tool.
Three cases from the field
Case one. Global site with many countries
A consumer brand runs one global site that feeds thirty country sites. Global owns copy and design. Markets translate and swap offers. The pattern that works looks like this.
Blueprint at /content/global with clean sectioning. Language roots under each country like /content/site/us/en and /content/site/fr/fr. Make language copies first, then live copies from the matching language. Pick one rollout config that pushes new pages and moves but does not clobber local properties. Mark a few components as structure only so authors cannot break global navigation.
Translation runs through projects tied to the language roots. Do not translate from a country copy back into the blueprint. That loop is chaos.
Case two. Regions share templates but have different release dates
A tech vendor ships in waves. Americas gets features first. EMEA follows. Pages are the same but launch times differ. The trick is to separate structure from timing.
Keep one blueprint for structure and content seeds. Use live copies per region with inheritance kept on. Authors in each region schedule activation on their timeline. Do not fork templates. Use policies to keep component behavior the same everywhere. You get one content shape and many clocks.
Case three. Campaign microsites that borrow from the main site
Marketing wants fast campaign sites with brand styling and a few custom modules. Full MSM is too heavy for short runs. The sweet spot is a thin blueprint that carries only shell pages, header, footer, and tracking. Campaign content lives locally with no inheritance on the body.
This gives you rollout for fixes to header or legal while letting the campaign team move daily without a rollback drama.
Objections and replies
Objection. MSM is brittle and authors turn off inheritance anyway.
Reply. That happens when the blueprint owns too much. Keep navigation, header, footer, and core page fields in the blueprint. Let markets own body content and local promos. Inheritance stays on because it helps, not because process says so.
Objection. Translation connectors will fix our structure.
Reply. Connectors move strings. They do not correct a broken tree. If language roots mix locales, jobs will go to the wrong place and you will chase phantom bugs for weeks.
Objection. We need speed. We will clean it up later.
Reply. A one day planning session saves months of rework. Draw the tree, lock down a rollout config, and agree on what markets can change. That is real speed.
Action oriented close
Do this before you clone any site
- Sketch the content tree on a whiteboard. Blueprint at the top. Countries or regions under it. Language roots under each market. Keep it boring on purpose.
- Pick one rollout config and write it down. New pages roll, moves roll, critical properties roll, local body stays local. Freeze that choice for the first wave.
- Define what is global and what is local by component. Navigation, header, footer, tracking are global. Hero text and promos are market owned.
- Standardize language codes and paths. Use the AEM language copy tool to create them. No hand made folders for languages.
- Train authors on two moves. Turn inheritance off for a field. Reroll a page from the blueprint. Practice this in a throwaway site.
- Run a pilot. One blueprint, two markets, two languages. Measure time to first publish, number of rollout conflicts, and number of local overrides per page. Adjust the rules once.
AEM gives us plenty. The SDKs and Touch UI are getting smoother with each drop. None of that matters if the tree is random. Get the structure right, then press the scale button. Your authors will thank you and your rollouts will feel boring in the best way.
