Seo - Custom domain with Medium

Hi,

In terms of SEO, what is the best approach when choosing a custom domain(blog.mydomaindisplay.com) or a subdomain of the medium(mydomaindisplay.medium.com)? If I use custom domain like blog.mydomaindisplay.com, would it be difficult/delayed for search engines to index my articles?

Thanks

medium is bigger and better so it will index faster... well, in theory anyway...

But having your own domain is the most important thing when it comes to running an online business. If you have your own domain you are in control of everything and even if it takes a bit longer to get your domain indexed and ranking in google it's still worth it
