Good to hear from you again. Of course – it’s possible and it’s very simple. Try to use free AI web builders. In this case, artificial iIntelligence will do everything for you – select the web template, color scheme, structure of the mockup, needed sections and more. All that is required of you is to answer questions – then everything will be done automatically according to your preferences.
Just imagine Medium shuts down as did Posterous back in the days (which was a similar service). You will not necessarily lose all your content but all the SEO rankings you ever created. To get it right you need to publish on your own domain name and preferably on your root domain (www.yoursite.com/blog) and not a sub-domain (blog.yoursite.com). This has numerous SEO advantages.
