HTML <em> Tag vs <strong> Tag

The <strong> tag is used to indicate the text having more importance from the rest of the content on a webpage. On the other hand, the <em> tag is used to change the meaning of the content as the spoken emphasis does.

Both the <em> and <strong> tags can be nested together for a higher degree of importance.

HTML <b> Tag vs <strong> Tag

We are generally confused between the <b> tag and the <strong> tag/ Let us clear this out, the <strong> tag is used to denote the content having strong or higher importance, whereas the <b> tag is used to draw the attention of the reader without indicating that the text is of higher importance.

So the <b> tag simply adds style, whereas the <strong> tag adds meaning to the text, informing the browser or search engine that the enclosed text is important.
