comparison dimension	Multisite	multidomain architecture
Number of installations	Manage multiple sub-sites with one WordPress installation	Separate WordPress installation for each site
database structure	Sharing a database with different table prefixes for subsites	Separate database for each station
Management Portal	Unified management of all sub-sites in one backend	Separate management back office for each site
Plugin/Theme Control	Unified control of the master station, the sub-station can not independently install plug-ins	Plug-ins can be freely selected and installed at each station
System resource consumption	More efficient resource utilization and centralized maintenance	Consumption of resources is decentralized and requires maintenance on a station-by-station basis
SEO Independence	Sub-site SEO is affected by the main domain	Each domain name participates in the ranking independently, the weight is clearer
Difficulty of operation and maintenance	Centralized management is more efficient, but configuration is relatively complex	Independent configuration of each site, suitable for independent maintenance of different projects
