One of the biggest challenges for folks new to building a website with WordPress is that it feels very much like writing/blogging software out of the box. Yes, you can create pages, but as soon as you want to structure information in columns or do anything more complex than images and text you will quickly find you need to find a theme or a handful of plugins to get the job done (and if you don't know what you don't know, that's a huge hurdle). "Site Builder" plugins are becoming more and more popular and you even see more themes integrating them into their frameworks these days. Some are pretty good, some suck really badly. One I really like and wanted to demonstrate as a way to quickly get up and running with a WordPress site is Elementor which is both free (there's a Pro version that has more features I'll discuss in a bit) and incredibly user-friendly with a lot of great options.
While I know more than the average WordPress bear, I’ve never really seen the value of any of these site builders myself.
I am curious how some of these site builders will do with the upcoming release of Gutenberg, however.
