John Mueller states:
“As far as I know, our search systems don’t look for any particular content management system to treat it differently. For us, a CMS is just one way of creating webpages. Google systems don’t focus on how the page was created. Instead, they focus on the final result. Hand-created webpages can be just as good as those generated by WordPress, Wix, Squarespace, or similar.”
