Optimizing your single page application Vue.js for search engines (SEO) is not a simple task, in this short guide you will have an overview of tools and libs Vue.js that will help you to have a better result + several good practice tips in SPAs.
SEO (Search Engine Optimization) are practices to be followed to optimize your site for search engines, improving its ranking, bringing better quality and increased traffic, thereby generating much more visibility for the site.
