For example:

  1. In a product description in a store, what are the best practices for bolding a product name that appears in the product description?
  2. In a Blog, should you bold keywords for SEO, emphasis to the reader, both, or are there other reasons to utilize bold?

Below are the correct usage of the four elements to choose from. I would say if you are marking out something as important, you should use strong. Markup your content correctly. You never know the benefits. The content could be consumed by a screen reader, a RSS reader, insta-paper or some other uninvented device in the future.

Your Sites stylesheets should then take care of bolding the marked up words.

Usually marking your content up in a semantic way as possible has a net positive affect on SEO too, but a few strong words probably won't proppel you to number one on their own.


i — alternate voice such as transliterated foreign words, technical terms, and typographically italicized text

b — “stylistically offset” text, such as keywords and typographically emboldened text

em Stress emphasis, i.e., something you’d pronounce differently

strong — strong importance


From a UX point of view, I generally bolding words and sentences in a way that if the user only reads them, they will still get the idea of the text. It makes the text more scannable.

I don't think bolding text can have a true impact on SEO.
