What does the company do well? It is seamless. I bought my domain name, and once the purchase was complete GoDaddy instantly took me to their integrated Website Builder. It has a great user interface, and is a huge improvement over the c-panel interface from early 2000's GoDaddy.
What does the company not do well? You don't have as much control as a custom developed Wordpress sight. I was able to get the GoDaddy Wordpress Builder to visually do exactly what I wanted. However, I wasn't able to optimize the speed of my site as much as I can with a custom developed site.
What do you wish you had known about the company before using? I wish I had tried this sooner. I overlooked it before, because of my previous experiences with GoDaddy back in the early 2000's. However, when I decided to build my personal site I didn't want to spend the time building a custom Wordpress site, and GoDaddy was their to the rescue.
