SEO is the name of the game when it comes to publishing content. If you care enough about your content to use a headless CMS, we're assuming this matters to you.
We don't provide an SEO component, per se, because the solutions that exist are all very much dependent on the stack you use (and whether or not you use server-side rendering, etc.). However, we do provide a lot of SEO focused attributes in our components like microdata.
That being said, we thought it would be a good idea to provide a list of recommended SEO components depending on the framework you use:
If you have any others we should add, please email us at firstname.lastname@example.org and we'll be glad to place it on the list.
