When you purchase Yoast you are given a subscription to the plugin.?That subscription entitles you to support and plugin updates for?one year.?After that, it needs to be renewed.?When it comes time to renew the plugin we do offer a renewal discount for being a loyal user (currently 20%).
If you did not renew your subscription, then you can continue to use the plugin features as they are on your site. A subscription is required for updates and support.?How can I get support without a subscription?
In other words,?if you won’t renew the subscription, the plugin will continue working on your site after the subscription has expired. For how long, we could not say as this depends on a number of factors including updates to WordPress core, plugins and themes.
If you would like to purchase the plugin and gain access to the premium technical support, you can purchase a subscription for Yoast SEO Premium here.
