WordPress is more widely used
WordPress powers roughly 43% of all websites, hundreds of millions of sites, from personal blogs to household-name brands. That popularity works in your favor: more people are familiar with it, more tutorials and answers exist for every question, and more WordPress experts are available for hire. Wix and Squarespace have grown, but neither comes close to WordPress’s reach.
WordPress is also more flexible
With WordPress you can build any type of website you want. Tens of thousands of plugins and themes let you customize your site to fit your exact needs, and the block editor and Site Editor give you visual control over every page without code. Just as important: you own your site. WordPress is open source, so you can export your content, switch hosts, or extend it however you like. Wix and Squarespace are closed platforms, if you outgrow them, moving away is painful.
WordPress itself is free
Wix and Squarespace charge monthly platform fees, and most add-ons cost extra. WordPress is free, open-source software, you only pay for hosting, and thousands of free plugins and themes cover almost anything you’d want to add.
If you want the most capability for your budget, and the freedom to grow without platform limits, WordPress is the clear winner. Pair it with reliable hosting and you have everything a small business needs to succeed online.
