No problem! We can manage websites for you whether you're running 1 or 10.
Our care plans each cover one single site, domain, subdomain or WordPress installation. If you have multiple sites as subdomains of a site (e.g. yoursite.com and subdomain.yoursite.com) they still count as separate sites. If you have 3 websites that you'd like us to manage, you'll need 3 plans, one for each site.
You are more than welcome to choose different plans for each website depending on the needs of each individual site.
