In June 2018, what is the best non-coding website builder for SEO?

Its WordPress.com: Create a free website or blog as per my opinion. the builtin Jetpack plugin sorts out many SEO related issued automatically. but then the best plugin for SEO is Yoast. its fully compatible with wordpress and helps you create page, image, video or blog titles in a better manner. it also shows you the quality score of your SEO for a particular page, blog or any other content which you upload on the WordPress.com: Create a free website or blog portal. it helps you make corrections in your meta descriptions and text readability too. sometimes one forgets to create a link or upload an image on a particular page or blog and the plugin prompts you to rectify your mistake in that regard too. then it generates a sitemap which helps you connect your website to bing and google webmaster tools too. that helps the search engines in indexing and crawling your pages, articles, images etc. in a better way than others. you may choose the free plugin by Yoast but the premium version helps in more optimization as redirects are simpler and it also advises you on matters such as internal linking. WordPress.com: Create a free website or blog in itself is the best platform for optimizing websites hosted on its portal and the Jetpack or Yoast plugins fine tune your website for a better visibility on Google and Bing. Another advantage with WordPress.com: Create a free website or blog is that it automatically generates AMP compatibility for your website. The Yoast or Jetpack plugins enable an additional boost to the technical aspect in this regard.
