WordPress
Roughly 44% of websites online today are built in WordPress. Therefore, support is much easier to find. A WordPress website does not tie an organization down to a particular developer and creates options for the client. Additionally, WordPress has a robust library of plugins that make functional changes fast, easy and generally inexpensive. Most small and mid-sized businesses do great with WordPress as their platform.
Shopify
About 10% of websites are built in Shopify and you have likely used this platform to order products. Shopify offers excellent technology for commerce and has many apps available to accommodate all types of requirements (subscriptions being one popular utility). Shopify works well for organizations who run a significant number of transactions online and/or use the Internet as their primary storefront.
Webflow
Less than 1% of websites are built in Webflow. Marketing/Agencies often utilize this platform because it focuses on design / visual development. While market share has doubled in the last year or so, it is still difficult to find developers who specialize in this platform so options are somewhat limited. Additionally, the Internet landscape currently favors function over design (i.e. over 70% of views are mobile) so a WordPress or Shopify website is often a better solution for small and mid-sized businesses.
Do-It-Yourself (DIY) Platforms
Platforms like Wix and Squarespace dominate the DIY space. These platforms are excellent for folks with small budgets who would like to set up their own web presence. Home-based businesses, sole proprietorships or part-time ventures can successfully create a website on a DIY platform. Small and mid-sized businesses should avoid DIY platforms and go with WordPress or Shopify depending on requirements.
