According to a recent Search Engine Journal article, WordPress, Shopify, and Wix now control about 73% of the entire content management system market.
WordPress holds around 60% of the content management system market share. Shopify accounts for about 7%, while Wix holds roughly 4% to 6%.
Shopify posted $11.56 billion in revenue in 2025, up 30% year over year. Wix reached $1.99 billion and reported its second consecutive year of operating profit.
What Does This Mean for SEO?
Modern CMS platforms now handle many technical fundamentals like sitemaps, canonical tags, and basic site structure.
For most sites, “good enough” technical SEO can be built in from day one.
The real value of SEO is shifting toward strategy, problem-solving, and decision-making, in addition to technical implementation.
For example, companies will still likely work with a technical SEO agency or consultant during a website migration, redesign, or when moving from one CMS to another.
Platform changes come with real risk. Redirect limits, URL structure differences, and missed details can lead to significant traffic loss.
This is where experienced SEO guidance matters most.
Each CMS handles SEO differently. For example, WordPress offers SEO plugins, while Shopify includes built-in features like SEO titles and meta descriptions.
Knowing what’s automated, what’s customizable, and what’s missing helps SEO professionals guide clients through website migrations and on-going SEO work.
Going forward, SEO will combine technical implementation with strategy, risk management, and visibility across search and AI platforms.
