More about bold and strong tags

The difference between the two is that a strong tag semantically emphasises text as important, while a bold tag simply makes text visually look bold.

This distinction is grounded in the way HTML code distinguishes between physical-visual HTML tags, and semantic-logical HTML tags. While strong refers to the meaning of the tagged text, bold is merely an optical display direction for browsers.

The importance of Bold and Strong tags for SEO is a matter of debate. Google says its search algorithm makes no distinction between them when indexing websites.

That would mean there is no purely technical advantage to using them in SEO terms. However both tags can be used to improve readability. If the content of a web page is easier for readers to comprehend, it will also be easier for search engines to understand and index. 

Improving the user-friendliness of a website makes it more likely people will spend time on it, explore it more deeply, and share its content – all signals that search engines consider when calculating rankings.
