The ties between companies is critical to your success on WordPress. As a platform provider we solve so many technical issues for our partners with regard to the integration and setup of the environment for you and relieve many of the technical issues that can happen.
Our partners are selected based on their technical merit and market share. For example, Yoast SEO does not have a partner program, but they are the predominant plugin for SEO, so that is what we offer and support. It is also important to know which technologies are compatible with each other. Example: We are adding the Divi Page Builder because it has native support for Constant Contact email marketing.
