In the world of marketing and sales, words are everything. They convey your brand’s personality, establish credibility, and create lasting impressions. Grammar is pivotal in ensuring your brand’s message is received as intended—professional, polished, and trustworthy. Conversely, poor grammar can lead to miscommunication, reduce trust, and, in the worst cases, damage a brand’s reputation.
A brand with grammatically correct communication signals attention to detail and professionalism. It tells your audience, We care about every aspect of our work. In contrast, grammar mistakes may suggest carelessness, lack of expertise, or even a disregard for quality. This can be a deal-breaker for consumers, as they often equate sloppy communication with subpar services or products.
Grammar also impacts SEO and visibility. Search engines like Google reward well-written, clear content and may minimize pages with errors that make your website seem less credible. Social media engagement is similarly affected. Posts riddled with mistakes are less likely to be shared or trusted, reducing your reach and overall impact.

Grammarly Changed My Writing
As a professional, ensuring grammatical accuracy in my content is critical. Before using Grammarly, I struggled with typos, to the horror of my friends and colleagues who were professional writers. These mistakes impacted how my audience perceived my expertise and, by extension, my brand.
Grammarly became a lifesaver. The premium version transformed my writing process from correcting minor errors to suggesting stylistic improvements. It didn’t just fix mistakes; it taught me why they were wrong, helping me grow as a writer. And I still get weekly updates from Grammarly to educate me on my errors. Here are my top 5:
- Missing Article: Failing to include “a,” “an,” or “the,” which can make sentences unclear (e.g., She adopted puppy from shelter instead of She adopted a puppy from the shelter).
- Unnecessary Ellipsis: Using ellipses where they are unnecessary, often creating incomplete or awkward sentences (e.g., I was going to tell you… but never mind instead of I was going to tell you, but never mind.).
- Missing Period: Forgetting to end a sentence with a period, making the text seem unpolished or confusing (e.g., We visited the museum today and it was amazing instead of We visited the museum today, and it was amazing.).
- Squinting Modifier: Placing a modifier in a way that creates ambiguity (e.g., Students who study occasionally pass the test could mean studying occasionally or passing occasionally).
- Incorrect Use of Commas: Adding a comma where it doesn’t belong or failing to include one where it’s needed (e.g., After dinner we watched a movie instead of After dinner, we watched a movie.).
