Sure, that is in all probability tremendous apparent to most of you studying this web site however Gary dives a bit deeper.
He stated, “Amongst different issues, search engines like google and yahoo use the HTML of your pages to make sense of the content material. If for instance you break up paragraphs, take away H tags in favor of CSS styling, or add breaking tags (very true for CJK languages), you modify the HTML parsers’ output, which in flip could change the location’s rankings.”
Briefly, when redesigning, positive – go forward – make the location fairly. However altering the core HTML may end up in rating adjustments.
