I've upgraded my site's layout - changed it completly and built a new one from scratch (even though I did not use dynamically generated content, ajax calls or parallax effects).
I kept the same content (same text and same page names), but changed the layout (and, of course, the css).
Will this change affect my search ranking?
From what I know, google reads only the text within pages, so that would mean it's totally safe to upgrade my site. Am I correct?
