Agree with your overall sentiment, but should clarify this: > I have seen no evidence to suggest that search engines care about HTML5 semantic tags I think you mean "HTML5 sectioning elements" (header, footer, section, article, aside, main). Because search engines absolutely positively do care about proper "semantic" use of other tags (especially h1...h6).
