Key Differences
The <b> tag is a purely stylistic element. It makes the text appear bold but does not communicate any extra meaning to browsers, screen readers, or search engines. It is like using a highlighter pen just to make text stand out visually.
On the other hand, the <strong> tag not only makes text bold but also adds semantic meaning. It tells browsers and assistive technologies that the text is important or should be strongly emphasized. For example, screen readers may change their tone or announce the text differently to help users understand its significance.
In modern web development, using semantic tags like <strong> improves accessibility and SEO because it conveys meaning beyond just appearance. The <b> tag is best reserved for cases where you want bold text without implying importance, such as keywords or product names.
