Since WordPress launched in 2003, it's held the dominant share of the CMS market. According to W3Tech, the popular platform currently stands at 64.1% market share.
How large is the CMS market?
According to W3Techs, 68.9% of websites have a CMS, and Netcraft reports 1.15 billion live hostname websites. From this, we can assume that the current market size for content management systems is approximately 796 million websites.
Top 10 CMS by market share (globally)
The top ten is an interesting read. No prizes for guessing who occupies the number one spot, but I was surprised by some of the players lower down the list:
Why does the CMS market share matter to someone working in SEO?
There are also lots of useful comparisons between different options. Of course for now, WordPress retains its dominance in the CMS market share, but website builders such as Wix, Squaresapce, and Shopify are on the rise, indicating where market growth lies, especially for small businesses.
If more small businesses are switching to website builders, understanding the limitations and intricacies of these platforms for SEO could be a competitive advantage. Shopify is installed on 4.3% of all websites (not just sites with a CMS): a total potential market of 50 million websites. With their increasing market share, specialising in Shopify SEO could be a strategic move for an SEO professional.
Similarly, specialising in Wix and Squarespace is a way to differentiate yourself from the competition. WordPress might be dominant now, but that also means that many other people are servicing that specific CMS.
What do you think? Could aligning with a more niche CMS provide more new client opportunities?
