What's the difference between <b> and <strong> tags?

Answer 1

The b element represents a span of text offset from its surrounding content "without conveying any extra emphasis or importance", and for which the conventional typographic presentation is bold text; for example, keywords in a document abstract, or product names in a review.

<strong> is different. It "represents a span of text with strong importance." There is semantic meaning of importance here. In fact, a <strong> tag within another <strong> tag has even more importance. There is nested importance. ;]

Answer 2

can we use both <b> and <strong> in place of each other...... does it affects search engine crawlers...which one will be better for higher ranking in search result
