You've seen it everywhere. It's on gym walls, shouted in sports stadiums, and plastered across million-dollar marketing campaigns. But honestly, half the time, people are getting the punctuation wrong. If you’ve ever paused mid-text wondering whether to hit that apostrophe key or just blast through with lets go, you aren't alone. It’s one of those tiny linguistic quirks that feels pedantic until you’re the one looking like you skipped third grade in a professional email.
Language is messy.
Technically, let’s go is a contraction of "let us go." That apostrophe isn't just decoration; it’s a placeholder for the missing "u." When you say "Let's go to the beach," you're literally saying "Let us go to the beach." Take the apostrophe out, and you’re left with "lets," which is the third-person singular present tense of the verb "to let" (meaning to allow or permit). "He lets the dog out." See the difference? One is an invitation to action, and the other is about permission.
Why the Apostrophe is Dying (and Why You Should Care)
We’re living in a "good enough" era of digital communication. Autocorrect usually saves us, but it’s remarkably inconsistent with contractions that have homonyms. If you type lets go into a search engine or a quick DM, the world doesn't end. People get the gist. However, in the world of SEO and brand authority, these "minor" errors actually bleed into how readers perceive your expertise.
Think about the vibe of a brand.
If a high-end fitness app uses "Lets Go" in their primary call-to-action, a certain subset of the population—the ones who notice details—subconsciously flags it as sloppy. It’s like wearing a tuxedo with flip-flops. Sure, you're dressed, but something is off. On the flip side, the phrase has become such a massive cultural trope that the "incorrect" version is often used intentionally for aesthetic reasons in graphic design. It's "cleaner" without the floating dot. But "cleaner" doesn't mean "correct."
The "Let Us" Litmus Test
Here is the easiest way to never mess this up again: just expand the contraction in your head.
Does "Let us go" make sense in the sentence?
- "Let us go to the store." (Works. Use let's go.)
- "She let us go to the store." (Works, but wait—this is past tense or a different structure.)
- "He lets us go every Friday." (Works. No apostrophe.)
The word "lets" (no apostrophe) almost always follows a subject like he, she, it, or a specific name. Sarah lets her kids stay up late. The gate lets water through. If there is no person or thing doing the "letting" right before the word, you almost certainly need that apostrophe.
Cultural Impact and the "Let's Go!" Hype
Beyond grammar, let's go has morphed into a universal battle cry. It’s no longer just about physical movement. It’s an expression of hype, victory, or intense anticipation. In the gaming world, specifically on platforms like Twitch and YouTube, "Let’s go!" is the default reaction to a clutch play or a rare loot drop.
According to linguists who study internet slang, the phrase has undergone "semantic bleaching." This means the original meaning (an invitation to move from point A to point B) has been washed out, replaced by a pure emotional signal. When a streamer yells it after winning a match, they aren't asking anyone to go anywhere. They’re just venting adrenaline.
Interestingly, this is where the spelling gets even lazier. In the heat of a Discord chat, nobody cares about apostrophes. You'll see "LETS GOOOOO" with twenty O’s before you see a perfectly punctuated sentence. This creates a feedback loop where the incorrect spelling starts to feel like the "authentic" way to express excitement, while the correct version looks "stiff" or "corporate."
Real-World Stakes: Business and Branding
If you’re a business owner, this is where it gets tricky. Do you go with the grammatically correct let's go to appear professional, or do you drop the apostrophe to look "edgy" and "with the times"?
Major brands have fumbled this.
I’ve seen billboards for local gyms that read "Lets Go Get It." It looks cheap. It suggests a lack of proofreading. If they can't get a four-letter word right on a $2,000 billboard, are they going to keep track of my membership billing correctly? It sounds harsh, but consumers make these micro-judgments every day.
There are exceptions, of course. In logo design, punctuation can sometimes disrupt the visual balance. If you are designing a minimalist streetwear brand, you might consciously choose "LETS GO" because the apostrophe creates "visual noise." But that’s a stylistic choice, not a grammatical one. You have to know the rules before you can break them effectively.

Common Misconceptions About English Contractions
A lot of people think that because "its" and "it's" are so confusing, let's go must follow some weird possessive rule too. It doesn't.
English is famously a "Frankenstein" language, but the rule for "let's" is actually one of the few consistent ones. "Let's" is always "let us." Period. There is no possessive version of "let." You can't own a "let."
Also, don't confuse this with "let’s" as a contraction for "let is" or "let has." Those don't exist. Unlike "he’s" (which can be "he is" or "he has"), "let’s" only has one job. It’s the "us" contraction. That makes it one of the easier rules to memorize if you just stop overthinking it.
How to Use "Let's Go" Naturally in Writing
Writing like a human means knowing when to be formal and when to let loose. If you’re writing a blog post or a social media caption, let's go is a great way to build rapport. It’s inclusive. It pulls the reader in and makes them part of a team.
"Let's go over the details" feels way more friendly than "I will now explain the details."
But watch your frequency.
Overusing hype phrases makes your writing feel like a cheap sales pitch. If every paragraph starts with an invitation to "go" somewhere, the reader gets exhausted. It’s like that one friend who is always "on" and shouting—it’s fun for five minutes, then you just want them to sit down and be quiet.
Variations That Work
Sometimes you don't even need the phrase. Depending on the context, you can swap it for something more specific:
- "Let’s dive in" (Commonly used in tutorials)
- "Shall we?" (Very formal, almost cheeky)
- "Get moving" (More aggressive/authoritative)
- "Time to start" (Clear and functional)
Honestly, though, let's go is the king for a reason. It’s punchy. It’s two syllables of pure forward momentum. Just... please put the apostrophe in there.
Why Search Engines Care
You might wonder if Google cares about your apostrophes. The answer is: mostly no, but also yes. Google’s algorithms are smart enough to know that someone searching for "lets go" is looking for the same thing as someone searching for let's go. They use "fuzzy matching" to account for human error and laziness.
However, "helpful content" updates prioritize E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness). If your entire website is riddled with basic grammar errors, it sends a signal that the content might be low-quality or AI-generated without human oversight. Humans notice the error, they bounce from the page, and your "dwell time" drops. That's how a missing apostrophe kills your rankings.
Actionable Takeaways for Your Writing
If you want to master this and keep your writing sharp, follow these steps:
- Audit your CTA buttons. If your website has buttons that say "Lets Go," change them to Let's Go immediately. It’s a 5-second fix that boosts your professional image.
- Check your subjects. If you wrote "lets," look at the word before it. Is it he, she, it, or a name? If not, you need an apostrophe.
- Read it aloud. Contractions should sound natural. If "let us" sounds weird when expanded, you might be using the wrong verb altogether.
- Style Guide Consistency. If you’re working for a brand that insists on dropping the apostrophe for "the aesthetic," make sure it’s a documented choice in your style guide so it looks intentional rather than accidental.
The difference between let's go and lets go is more than just a tiny mark on a screen. It’s the difference between being a leader of the conversation and someone who just didn't check their work. In a world full of automated, sloppy content, the person who gets the small things right is the one who wins the long game.
