During an Ask Googlebot session, one SEO professional asked John Mueller whether their choice of CMS (content management system) is something that matters for good rankings.
John answered that first of all, Google’s search systems don’t look for any particular content management system to treat it differently.
For them, a CMS is just one way of creating web pages.
Google does not focus on how the page was created.
Instead, they focus on the final result. Hand-created web pages can be just as good as those generated by WordPress, Wix, Squarespace, or similar.
As far as John can tell, all mainstream CMS systems can create pages that work well in search.
For the most part, SEO is not magic. It’s well-documented, and there are many testing tools.
So all providers can include SEO elements if they choose to do so. There are slight differences across systems just like all web pages are slightly different.
But, for the average site owner, they either all work well for search, out of the box, or can be easily tuned to work well with a few settings or plugins.
