Maximize SEO of your multistore mode with subfolders (not subdomains).
Multistore is an awesome way to manage multiple online stores from the same dashboard—even cloning certain shops and products and offering them in different languages and locations with per-store pricing, extensions, banners, and order flow. However, from an SEO standpoint it can difficult to increase the rank of subdomains because they’re treated as separate websites, even if they have one shared parent host. To solve this issue, a developer can create a subfolder model of your multistore. Check out this tutorial for Creating an OpenCart Multi-Store Sub-Folder.
