In 2022, which technology will be most effective in e-commerce?

Hard to bet against Shopify long term

Shopify is a better "all-in-one" solution for building an online store. But in WordPress, we have more control over the exact technical solution used for selling online. And I believe both of them will remain the most effective solutions even in 2022.

I work with WooCommerce and don't pay a single dime for it. You might oppose me, saying there can be too much extra garbage this plugin may be planting on my website, but I got to https://rubyroidlabs.com/service... who cleaned the code on my website and customized categories, so that it didn't have any duplicates etc. on Woocommerce. And they designed a unique template for my website too.
