Here is an uncomfortable truth about the testimonials on your page: almost nobody reads them. Not the way you hope, anyway. A visitor scanning a landing page gives each quote a second and a half at most, and in that time their eye snags on whatever stands out — a name, a photo, a bolded phrase — and moves on. Which means the words you choose to bold aren't a cosmetic detail. They are, for most readers, the entire testimonial. Get the emphasis right and a skimmer walks away with your strongest proof point. Get it wrong and they walk away with nothing, or worse, with the wrong idea.
Skimmers read the bold, then decide whether to read the rest
Think about how your own eye moves down a page of text. It doesn't crawl left to right, line by line. It jumps, landing on the things that break the visual pattern — and bold text is the loudest pattern-break in a paragraph. So a bolded phrase does two jobs at once. First, it is the message for the majority who never read the surrounding words. Second, it's the hook that decides whether the minority reads on. A well-chosen bold phrase makes a skimmer think "wait, that's exactly my problem" and slow down. A poorly chosen one gives them permission to keep scrolling.
That means the goal of bolding isn't decoration and it isn't "highlighting the nice part." It's compression: what is the single phrase that, read alone, delivers the most persuasive piece of this testimonial? Everything else in the quote is context for the reader who stops. The bold is for everyone.
Bold the result, not the compliment
The most common mistake is bolding the praise. A testimonial says "The team was fantastic and the onboarding was so smooth — we cut our reporting time from three days to about two hours." The instinct is to bold "fantastic" or "so smooth," because those words feel like the endorsement. They aren't. They're opinion, and skimmers discount opinion instantly because every testimonial has some. The line that actually persuades is cut our reporting time from three days to about two hours — a specific, verifiable result that a competitor's testimonial probably doesn't have.
The rule is simple: bold the concrete outcome, not the adjective. Numbers, timeframes, before-and-after states, and specific changes carry proof. "Amazing," "great," "highly recommend," and "game-changer" carry none — they're the words readers expect and therefore ignore. If a testimonial has no concrete result to bold, that's not a formatting problem, it's a sourcing problem, and it's worth revisiting how to write a testimonial request that gets a specific answer before you try to rescue a vague quote with formatting.
One emphasis per testimonial, or none of it lands
The second-most-common mistake is bolding too much. When half a testimonial is bold, nothing is emphasized, because emphasis is entirely relative — it works by contrast with the plain text around it. Bold four phrases and the reader's eye has four things to land on, no signal about which matters most, and the whole quote reads as shouted rather than pointed. The paragraph looks busy, the skimmer's eye bounces, and the compression you were going for turns into noise.
Discipline yourself to one bolded phrase per testimonial. If two candidate phrases feel equally important, that's usually a sign the testimonial is trying to make two points and would be stronger split into two shorter quotes, each with its own single emphasis. Forcing one choice also forces clarity: you have to decide what this particular testimonial is for, and a testimonial with a clear job outperforms one that gestures at everything. The same instinct toward ruthless trimming is what turns a rambling quote into something usable in the first place — see how to shorten a long rambling testimonial into a punchy pull-quote.
How to find the phrase in ten seconds
You don't need a system for this — you need a test. Read the testimonial once, then cover it and ask: if I could only keep five or six words from this, which would make a stranger with the same problem lean in? That phrase is your bold. Run three quick checks on your candidate:
- Does it stand alone? Read only the bolded words. If they still make a persuasive point without the surrounding sentence, you chose well. "From three days to two hours" stands alone; "so smooth" does not.
- Is it specific to this customer? If the phrase could appear verbatim in a competitor's testimonial, it's generic and you should keep looking. Emphasis should land on what only this customer could say.
- Would the customer recognize it as the point? The bold should feel like the heart of what they meant, not a phrase you cherry-picked to flatter yourself. Honest emphasis is more persuasive than manufactured emphasis, and readers can feel the difference.
Where this fits
Bolding is a small lever, but it compounds. On a page with six testimonials, the difference between "every quote's result is instantly scannable" and "every quote is a wall of grey text with the praise highlighted" is the difference between a proof section that works at a glance and one that only works for the rare reader who reads all of it. It matters most exactly where skimming is heaviest — near the top of a landing page, where a visitor is deciding in seconds whether your product is worth their attention. The through-line is the same one that governs every good testimonial decision: respect that the reader is busy, and do the work of compression for them. Bold the result, bold it once, and let the skimmer catch the value without having to read for it.
