Squarespace vs WordPress
If your needs are simple and you don’t plan on trying to sell things and grow, then Squarespace is fine. I have a friend who uses it and likes it, but he is only doing a personal blog. If you hope to one day have a store and want options then WordPress is better. In addition you have limited options to export data from Squarespace so you don’t have to recreate your work. Being able to move your data and work seems very important to me.
What makes WordPress so great? Probably its ability as a CMS and manage content easily for the average person. Databases are scary for most people but a CMS takes the best part of a database and makes it simple. If you have used a Microsoft or Apple program then you have the skills for WordPress. If you are considering upgrading your website you might want to also look at my suggestions for a good experience.
If you are new to WordPress shared hosting compared then you might want to read that link. It talks about my experiences with my attempts to used shared hosting. Shared hosting is when other people share the same server and you aren’t separated in any manner. So if their server causes a problem, then you go down. I experienced frequent downtime with shared hosting so I realized it wasn’t for me. I use VPS with InMotion and it works very well with me. I did not like my hosting experience with GoDaddy or Fatcow. Like many people I liked GoDaddy’s low domain registration prices but I learned my lesson. Now I use Namecheap and love it. Easy to work with and had features like privacy that GoDaddy charged more for.
