The <strong> tag in HTML gives strong emphasis to specific text. Often confused with the <b> or bold tag, the <strong> tag can also appear to bold a specific word, sentence, or phrase. So, what's the difference between the two? Strong is a logical state; it is meant for emphasis. Bold is about changing the physical appearance. In other words, bolding something adds more “ink” to the text, whereas one can change the properties of the logical state <strong> to show emphasis in multiple ways, such as underlined, in a different size, a different color, or whatever the designer chooses. Also, in text-to-talk programs, the words tagged with <strong> will be given emphasis as they are read aloud, whereas bolded words will not be emphasized. There are necessary uses for both types of tags. So, if <strong> provides emphasis, a designer should wrap all of the SEO keywords with <strong>, right? No. Text should always feel natural on a website, and providing emphasis to your keywords only can seem spammy to both users and Google.
