Next SEO

Next SEO is a plug in that makes managing your SEO easier in Next.js

Next SEO is a plugin that makes managing your SEO easier in Next.js projects. Pull requests are very welcome. Also make sure to check out the issues for feature requests if you are looking for inspiration on what to add. Feel like supporting this free plugin? It takes a lot of time to maintain an open source project so any small contribution is greatly appreciated. NextSeo works by including it on pages where you would like SEO attributes to be added. Once included on the page you pass it a configuration object with the page's SEO properties. This can be dynamically generated at a page level or in some cases your API may return an SEO object. Then you need to import NextSeo and add the desired properties. This will render out the tags in the <head> for SEO. At a bare minimum, you should add a title and description. But NextSeo gives you many more options that you can add.
