Making your LinkedIn summary stand out is easier than you think, and bolding text is a simple way to grab a recruiter’s or potential client's attention. This guide will walk you through exactly how to add bold formatting to your LinkedIn summary. We'll also cover smart strategies for using it effectively without looking unprofessional or spammy.
Your LinkedIn summary, now called the "About" section, is your one shot to tell your professional story in your own words. But let's be honest - most people don't read every single word. They skim. They scan for keywords, impressive achievements, and reasons to keep reading (or to click away). Bolding helps you work with that natural behavior instead of against it.
Here are the three big reasons to add a little formatting to your text:
LinkedIn’s editor doesn’t offer a built-in formatting toolbar like a word processor. You won't find a little "B" button to click. To get around this, you’ll need to use a Unicode text converter. It sounds technical, but it’s incredibly simple. Unicode is a standardized system that allows computers and phones to represent text from all over the world. Many text-formatting websites use Unicode to generate plain text characters that look bolded, italicized, or otherwise stylized.
Here’s exactly how to do it:
This is important: because you’re using special Unicode characters and not true HTML bold tags, some screen reading software used by people with visual impairments might not interpret the text correctly. It may read the letters one by one, pronounce them strangely, or skip them altogether.
For this reason, be mindful of what you bold. Avoid bolding mission-critical keywords that are essential for someone to understand your role. Instead, use bold for emphasis on things that are visually helpful but not strictly necessary for comprehension. For example, using bold to highlight a number in a result (like "25% growth") is generally fine because the number and concept are still intelligible if the bolding is missed.
Bold text is just one tool in your formatting toolkit. You can use the same Unicode converters to generate other styles that help organize your summary and add visual interest.
The biggest risk with text formatting is using too much of it. A summary overloaded with bold text, emojis, and symbols looks chaotic and detracts from your message. Follow these guiding principles to create engaging posts.
Think of bold text like a highlighter pen. If you highlight everything, nothing actually stands out. Limit yourself to bolding just a few key phrases or stats per paragraph. The goal is to draw the eye, not shout at the reader. A good rule of thumb is to bold no more than 1-3 short phrases in your entire summary.
Don't bold words just for the sake of it. Think about your goals. What are the key takeaways you want someone to remember after spending 30 seconds on your profile?
Consider bolding:
More than half of LinkedIn users access the platform on their phones. What looks good on your big desktop monitor might look compressed or awkward on a small screen. After you’ve saved your changes, immediately pull up your profile on your phone to make sure the formatting looks clean, readable, and professional.
Is your personal brand and industry formal and traditional, or modern and creative? An accountant might use subtle bolding for a key certification, while a social media marketer might feel more comfortable using bold text alongside a few relevant emojis. The formatting you choose should always align with the professional image you want to project.
