Should You Highlight a Keyword in Bold?
So, when I am offering feedback, I have often noticed that a lot of people make their keyword bold. Is this necessary, does it impact SEO, does it affect ranking? Let's find out.
As it turns out, this is an old technique, that was often used to fool the Google bots many years ago. Think of it in the same way as keyword stuffing - people were bolding words that actually had nothing to do with the subject of their content, in the hope of Google ranking their post for those words.
Nowadays, Google takes no notice of bold words and treats them just like the rest of your writing. In other words, they have no effect on ranking.
However, they could be seen as a "soft SEO strategy" because they can improve user experience. Initially, a reader will simply scan your post to see if it answers their questions. A few bold keywords will stand out and make it obvious what your post is about.
Just as in everything else, moderation is the key here. Only a couple of bold words in a paragraph. And don't bold entire sentences, otherwise, you will lose the emphasis on the important words.
