The WordPress plugin market is always in a constant state of evolution.
Certain high-quality WordPress plugins continue to stay on top year after year due to committed development by their owners and support from customers. Others fall behind and are replaced by newer plugins that have been released to the market.
Discussions about which plugins and solutions are best for WordPress users always generate a lot of debate. This is perhaps because there are so many fantastic WordPress plugins on the market and because we all use WordPress in different ways.
Despite the subjective nature of “Best Of” lists, we at aThemes wanted to share what we considered the best WordPress plugins of 2021. Our list is divided into 12 categories, and for each category, we have declared a free and a premium solution.
