What's a Markdown format?
Markdown is a lightweight plaintext markup language that you can use to add elements to plaintext documents rather than using the older WYSIWYG editor.
Hashnode's editor supports the Markdown syntax and allows you to format your articles easily.
Why should I set a canonical URL?
A canonical tag is a unique HTML element with a unique URL that helps search engines prevent duplicate content issues in SEO (Search Engine Optimization) by specifying the canonical or most preferred or original source version of a web page.
When you create a blog with Hashnode and map a custom domain, you already have total independence over your blog and canonical. You need to update the canonical URL of your posts on other platforms you have published on in the past.
Why is tagging a post important?
Tagging a post is crucial because it will make your post appear on your target audience feed (who follow the same tags), which increases your readership and clicks to your website when your blog post is shared on any social media platform.
Why do I have to log in again to react/comment on articles?
When you visit a blog on a custom domain for the first time, you'll need to log in to react to/comment on the articles. However, you only need to do it once. Whenever you visit the blog again, you can react and comment without logging in.
This only applies to blogs on custom domains. If the blog is on the hashnode.dev subdomain, you do not need to log in again.
