strong for importance. Acts like bold(b), but used for SEO

Answer 2

There is no difference visually actually, but <strong> simply implies the level of importance while <b> simply makes the word bold

Answer 3

<strong> is intended to tag a word/phrase that is important, while <b> just applies a bold typeface. Most of the browsers render <strong> as <b>, but semantically speaking, it's a slight difference. HTML5 was designed to be focused on the structure of documents, not on their styling, so <strong> is suitable while <b> isn't. Moreover, some search engines bear in mind (if you could say so :-D) the <strong>-ed pieces rather than the <b>'d ones, right because of the semantic meaning that <strong> has and <b> hasn't.

Answer 4

<b> is deprecated, but it'll work for world war II browsers
