I have multiple sites, do I need multiple subscriptions?

Note: this information goes for both multi-site and multilingual site installs.

That all depends on how many WordPress installs/domains you have. What does Yoast consider a domain?

Do you have 1 domain or subdomain and 1 WordPress install? You just need a subscription for one site, no matter how many subsites or languages you have!

If you have more than one domain name or multiple WordPress installs, you’ll need a subscription for the number of installs or domains you have. Starting from only 2 sites, you get a discount, automatically. See the discount chart here: Can I use the plugin on multiple sites?
