上記の結論がどこから来たのかを示すために、WordPressの市場シェアとWordPress用の最も人気のある電子商取引（eCommerce）プラグインの2つ（WooCommerceとEasy Digital Downloads）のマーケットシェアについての興味深い分析データをご案内します。
WordPress’ market share is 33.6% of all websites
W3Techsによると, WordPress powers 33.6% of all the websites on the Internet, including those without a content management system (CMS) or with a custom-coded CMS. Or to put it another way, WordPress powers over one-third of the web! And if you limit the data set to only websites with a known CMS, WordPress’ market share gets even more dominant.
In that case, WordPress holds a 60.5% market share for content management systems on websites with a known CMS. How does that compare to the market share of other popular content management systems? Let’s take a peek:
At the start of 2017, WordPress powered 27.3% of all websites. By April 2019, WordPress had made it to the current market share of 33.6%. Some quick math should tell you that WordPress gobbled up an additional 6.3% of the total website market – good for ~23.0% growth.
