Does Poor Grammar or Spelling Affect SEO?

Let’s get straight to the point — because, let’s face it, none of us are here for a grammar lesson unless it’s going to help our rankings. So, does poor grammar or spelling on your site affect your SEO? The answer is a classic “yes, but also no,” which is just the kind of clarity we all crave after our third coffee of the day.
Grammar Effect SEO: The Official Word
First, the facts. According to Google’s own John Mueller, spelling and grammar are not direct ranking factors. That’s right — Google’s algorithm isn’t running a red pen over your blog posts. But before you start celebrating by tossing your style guide out the window, there’s a catch: user experience. If your content reads like it was written during a power outage (or by a sleep-deprived intern), users will notice — and so will your metrics.
Bing, on the other hand, is a bit more old-school. They’ve publicly stated that error-free content can directly improve your rankings on their platform. So, if you’re targeting Bing users (hello, Edge default browser crowd), you’ll want to keep those typos in check.
Why Grammar and Spelling Still Matter for SEO
1. User Trust and Credibility
Let’s be honest: would you trust a financial site that can’t spell “investment”? Or a healthcare blog that mixes up “prescription” and “description”? Probably not. Poor grammar and spelling erode trust, especially in industries where accuracy is non-negotiable. As John Mueller put it, “If you are a banking website and you have terrible English on it, then I assume users will lose trust in your website.”
Trust leads to engagement, backlinks, and conversions. And while Google might not ding you for a misplaced comma, your readers (and potential customers) definitely will.
2. Engagement Metrics
Search engines are obsessed with user experience. If your content is riddled with errors, users are more likely to bounce — sometimes literally, if they’re reading on a yoga ball. High bounce rates and low time-on-site signal to search engines that your content isn’t valuable, which can drag down your rankings over time.
3. Readability and Comprehension
Ever tried to read a blog post that felt like it was run through a blender? Not fun. Errors make content harder to understand, which is a big problem for voice search and featured snippets. If your sentences don’t make sense, you’re not getting that coveted “position zero” spot.
Plus, search engine crawlers might struggle to interpret poorly written content, making it harder for your pages to be indexed and ranked correctly.
What the Experts Say
“Not really….it is more a matter of how it is received from a user point of view. If you are a banking web site and you have terrible English on it, then I assume users will lose trust in your web site.” — John Mueller, Google Search Advocate
“Just as you’re judging others’ writing, so the engines judge yours. If you’re not paying attention to the details on your pages, the engines may not be inclined to give you the benefit of the doubt.” — Duane Forrester, former Bing Senior Product Manager
Professional Advice: How to Avoid the Grammar Trap
- Proofread everything. Yes, even that “About Us” page you wrote at 2 AM. Tools like Grammarly or Hemingway Editor can catch what your tired eyes miss.
- Focus on readability. Short sentences, clear structure, and a friendly tone work wonders. If your content reads like a legal contract, it’s time for a rewrite.
- Monitor your metrics. High bounce rates or low time-on-site? It might be your grammar waving a red flag.
- Know your audience. In high-trust industries, even minor errors can have major consequences.
The Rise of AI Content (And Why Quality Still Wins)
With AI-generated content flooding the web, search engines are doubling down on quality and user experience. Well-written, error-free content stands out — especially when everyone else is churning out generic, mistake-riddled posts. If you want to be the needle in the haystack (and not just more hay), quality matters.
And that’s where we come in. At Blogging Machine, our AI agent doesn’t just crank out SEO-optimized articles — it does so with an eye for grammar, spelling, and readability. We automate the boring stuff (keyword optimization, topic research) so you can focus on running your business, not running spellcheck.
