I'm trying to understand the importance of author bios to Google and its latest algorithms. Some say author bios affect rankings, but others say that has not been specifically stated by Google — but it does affect the user experience. Anyone have input on this? Thanks!

Hello, my understanding was that Google reads hyphens in keywords as spaces, but if that's accurate how come keywords with hyphens that I research with Keyword Explorer — for instance, hospital-acquired infections — rank lower when I include the hyphen? If the hyphen hurts SEO, do I have to remove them all from the blog or page in question? Removing hyphens means a blog or page will have punctuation errors, which is irritating to an editor, but I don't want to sacrifice the effectiveness of keywords, either. Thanks, in advance, for your response!
