Top Grammar Mistakes and How Your Business Can Avoid Them

Top Grammar Mistakes and How Your Business Can Avoid Them

Content Writer: Lauren Snyder Lauren Snyder Content Marketing Specialist

As a business professional, you want to make the best impression on your potential customers. As digital marketing is becoming more and more important, your online presence is one of the first places your customers may see you.

You know what that means? Your grammar needs to be top-notch! No one is perfect and occasional mistakes aren’t the end of the world, but your business should try to be as grammatically correct as possible.

Think of it this way — if you see a Facebook post by a business you wanted to potentially shop at, but they made some obvious grammar mistakes, would you still want to shop with them?

Like I said, grammar isn’t make or break for everyone, but it’s an important aspect that your business needs to watch.

Keep reading to learn how to avoid the most common grammar mistakes.

Grammar Mistakes to Avoid

1. They’re vs. Their vs. There

I see this grammar mistake all the time, so let’s talk about the difference.

They’re is a contraction of they are, their is the possessive form and there refers to a place. Here are some examples of how they are used in a sentence:

  • They’re going to the meeting room.
  • I heard their marketing is great!
  • We are going there tomorrow.

2. It's vs. Its

This one can be a little confusing and even I get them mixed up on occasion.

It’s is the contraction of it is or it has while its is the possessive form. Use these examples to help you understand the difference:

  • I can’t believe it’s only Monday!
  • The customer left his jacket here. We should return the jacket to its owner.

3. Complement vs. Compliment

Did you realize that there was a difference between complement and compliment? Surprise!

Although these words are pronounced the same, they are quite different. Compliment is used as a form of praise, such as complimenting someone’s new coffee mug.

Complement, on the other hand, is adding to something to enhance or improve it, such as “That cover letter complements your resume.”

4. Affect vs. Effect

I will never judge you if you use the wrong form of this word because it can be complicated.

Affect is a verb while effect is a noun. Maybe that didn’t help, so let me break it down:

Jack is in a restaurant and wants to order dinner, which affects what his server is doing. After Jack eats his dinner, the effect is that his stomach is full.

Make sense?

 5. Me vs. I

I have a great tip to help you know whether you should use me or I in a sentence. Here's the example:

When you finish updating the menu, can you send it to Mallory and me? 

Believe it or not, that sentence is correct! If you take out the name Mallory from the sentence, using me instead of I makes much more sense.

 6. Never Double Space After a Period

Quick history lesson!

Back when people were learning to type on typewriters, they were instructed to put two spaces after a period. Why? Because typewriters used monospace typesetting, meaning that every letter was given the same amount of space.

Once they got to the end of their sentence, people would double space after the period to make it clear a new sentence was starting.

Guess what? You don't have to double space after a period anymore (unless you're still using a typewriter)! Offenders of this simple grammar mistake are typically ones that learned how to type on a typewriter.

7. Missing Comma After Introduction

I see this grammar mistake far too often, so pay attention to learn how you can avoid it!

When you're writing a sentence, you will add a comma after an introductory word, phrase or clause (exactly what I did in this sentence). This comma allows you to slightly pause and adds clarity to your sentence. 

Here's an example of an incorrect sentence:

In case you haven't heard I talked to the boss yesterday.

Without a comma, you will read the incorrect sentence all together rather than separating it with a comma to give you that slight pause.

The correct sentence would read:

In case you haven't heard, I talked to the boss yesterday.

Final Thoughts

Grammar errors can drastically change the meaning of your sentence if you're not careful! 

Even though grammar may not be the most important part of running your business, it can deter people from visiting your location. Use these final tips to stay a step ahead:

  • Whether you're writing a social post or a blog for your business, it's always a good idea to have someone else read over your work to help catch any errors.
  • There are also several online resources that can help if you're struggling with grammar. Check out Grammar Girl for some quick tips or Purdue Owl for more in-depth explanations. 
  • Bonus Tip: Read your sentences out loud! You will catch so many more errors reading your sentences out loud because they will sound weird if something is wrong. If you read them in your head, you will read what you think you wrote and not what you actually wrote.

Lauren - Your grammar tips are all spot-on and ones that I've been preaching about for years. But why is two spaces after the end of a sentence an "error"? It might not be the current style but, unlike the other grammar tips mentioned, doing so doesn't affect the readability or interpretation of the prose. I learned to type on a typewriter and would find it nearly impossible to change at this point in my life. Every sentence in this response has two spaces after the period and it looks good to me.

Hi, Allen! You are correct, it does not affect the readability. However, because most word processors use proportionally spaced fonts nowadays, it just isn't necessary to use double spacing. We also follow AP style, which indicates that you should only use one space between sentences:
