What might a typo cost you? Think about it. How much harm do you think one can do?

At 9:21 a.m. on July 22, 1962, NASA launched Mariner 1, a probe meant to conduct the first American flyby of the planet Venus. As it flew, it started drifting northeast of its scheduled path, and attempts to correct its course failed. At 9:26 a.m., the rocket was ordered to self-destruct.

One little missing line above an R in the codenot a hyphen, despite what many have reported over the years—cost NASA millions.

NASA is hardly your typical business putting out typical content, but this is a striking example of a small, fixable error being costly. Imagine pouring a ton of effort into something like a space probe only to have to blow it up because someone wrote something down wrong and nobody caught it.

That’s where proofreading comes in.

Proofreading is an essential part of business writing. It ensures accuracy, professionalism, and credibility in your content. It helps preserve your business’s reputation. It lets you communicate with your colleagues and clients. And, yes, it can shield you and your company from embarrassing and expensive errors.

In this article, I will share expert proofreading tips that will help you find those errors in your writing that could be costly. I will help you catch spelling and grammar issues, improve clarity and coherence, maintain consistency, and enhance the overall quality of your business writing. No matter your business, these tips will be a great benefit for your writing and will keep your reputation solid and safe.

Understand the Difference: Proofreading vs. Editing

Understanding the difference between proofreading and editing is greatly important in business writing. Editing involves evaluating the content for structure, coherence, and overall clarity. Proofreading, however, focuses on correcting surface-level errors such as grammar, spelling, punctuation, and factual inaccuracies. This is why proofreading is generally the last step when working on a piece of writing. Both processes are of great importance, but it is vital to do the right one at the right time.

  • Editing: Editing should come before proofreading. Editing is the process that ensures that your content is solid. It focuses on improving the overall quality and structure of the piece, addressing issues with clarity, coherence, organization, and more.

    Think of editing as the remodeling process. When you are editing, you find the major problems with your content, and you fix them.

    Some questions to ask yourself as you inspect your piece: 
    • Are your points arranged in an organized manner? 
    • Do they segue into each other smoothly? 
    • Do they reinforce each other? 
    • Is this piece saying what you need it to say?
    • Is it expressing the information in the way you want it expressed?
  • Proofreading: Proofreading is the step where you check for errors in grammar, spelling, and punctuation, and where you ensure that your text is accurate and consistent. It may sound a little less impressive than editing, but it is of equal importance in the writing process. Those surface-level errors have a massive impact on your finished project. They can cost you respect. They can cost you credibility. They can cost you money.

    Mistakes happen. It’s a fact of writing and a fact of life. When you don’t take the time to fix those mistakes, however—even the little ones—people notice. They see the typos in your content instead of your message. They come away thinking you are ignorant instead of knowledgeable, or that you simply do not care about your business. Or, if you have made a factual error, they come away with the wrong information. That can have disastrous consequences.

    In 2009, the UK government reported that the Welsh company Taylor & Sons Ltd. had gone bankrupt. The problem? It was a company called Taylor & Son Ltd. that had gone bankrupt. Soon after, clients lost faith, and the 124-year-old company with the S on the end was bankrupt, too. All over one letter.

    Proofreading prevents problems. Make that your new professional mantra:
  • Proofreading Prevents Problems

Focus on Grammar, Spelling, and Punctuation

Taking the time to focus on grammar, spelling, and punctuation is essential during the proofreading process. These are the nuts and bolts of writing, and they all need to be in the right place and used correctly no matter what type of writing you are doing. Solid grammar, spelling, and punctuation ensure the correctness and clarity of your writing, enhancing its readability and professionalism. By paying close attention to these elements, errors can be identified and corrected, elevating the overall quality of your content.

  • The Significance of Accurate Grammar, Spelling, and Punctuation: Accurate grammar, spelling, and punctuation are paramount in business writing. Each one contributes to clear communication, professionalism, and credibility. Proper usage of these elements ensures that the intended message is conveyed effectively, leaving a positive impression on your readers and avoiding any misunderstandings or confusion.

    When you are trying to communicate in business, clarity is crucial. That means you must use the right words, the right grammar, and the right punctuation. It’s easy to get these wrong. English is a minefield of a language, full of obscure rules and inconsistencies. You have to be careful. The wrong word or misplaced punctuation can change the meaning of a sentence entirely, and then your reader won’t understand the message that you are trying to convey. Take care to check and make sure that you are saying exactly what you mean to say in your piece.

    The wrong grammar, spelling, and punctuation also have a major impact on the impression your reader gets about your content, your business, and you. Typo-ridden, poorly constructed writing gives the impression of carelessness and ignorance. Clients and colleagues will lose faith in your abilities if you do not take the time to correct these errors. How can they trust you to meet their needs if you cannot be bothered to present them with polished writing? They may come away thinking that you lack the knowledge or the care to get the job done. It is important to present readers with your absolute best every time, and that means making sure your grammar, spelling, and punctuation are all ship-shape.

  • Tips and Techniques for Identifying and Correcting Errors: I go into more detail on techniques for identifying and correcting errors later in this article, but here are some quick, practical tips for finding issues.
    • Present your content to yourself in a different way: Try reading it aloud, or in another format. For instance, at the newspaper I work for, I print out everything I’m assigned to proofread, since that’s so different from proofreading on a screen. If the layout isn’t crucial, change the layout. Change the font.

      Anything that helps you see your content in a different light will help keep your brain from filling in the blanks and tricking you into seeing what it thinks you should see.
    • Use proofreading tools: These will not replace a thorough pass with human eyes, but they can point you toward issues that need a closer look.
    • Take a systematic approach: A systematic approach to reviewing each element of the writing is beneficial beyond words. Go slowly, and be methodical. Target each potential problem with a laser focus to ensure thoroughness and accuracy in your review.

Take a Moment to Double-Check Your Facts

Making sure the information you present in your content is factual is critical. Pay close attention to what you’ve included. Refer to the source of your information again if needed.

Taking the time to ensure that your content is factually correct is the difference between embarrassing—or costly—mistakes and polished content that will make you proud.

Pay Attention to Formatting and Consistency

Paying attention to formatting and consistency is essential in maintaining a professional appearance and ensuring a seamless reading experience. Consistent formatting adds an extra but vital layer of shine to your content, while maintaining consistency in writing style and tone help to establish credibility and professionalism.

  • Consistent Formatting: Consistent formatting plays a significant role in enhancing the professionalism of your content. It enhances your writing’s visual appeal, making it appear more dignified and readable.

    When you pay attention to your visual formatting, it establishes a sense of organization. This shows the reader that you are someone who cares about details, both small and large. A client or employer wants to know that their business matters are in good hands. Consistently formatted content presents the image that you are a professional who knows what they are doing and saying. You gain credibility from this appearance of professionalism, making clients more likely to choose you as the right person for the job or showing management that they already have the right person: you.

  • How to Maintain Consistency: To maintain formatting consistency throughout your document, establish a set of formatting guidelines or style rules for your writing. This should cover elements such as headings, fonts, spacing, indentation, lists, and more, depending on the sort of writing you are doing. If the company you are writing for uses a particular style guide, such as the Chicago Manual of Style, the Associated Press Stylebook, or one made just for the company, follow it closely, too.

    Apply these guidelines as you work, and regularly review your document for deviations during the writing process, and afterward. Pay close attention to each element as you proofread, making sure they match up as they should and follow your style guide. When you take the time to make sure that your formatting is consistent, it ensures a cohesive and professional appearance.

Utilize Proofreading Tools and Techniques

Utilizing proofreading tools and techniques can significantly enhance the accuracy and efficiency of your proofreading process. These tools may include grammar and spelling checkers, online proofreading platforms, readability analyzers, and style guides. Your own brain is the most valuable tool of all. Techniques such as reading aloud and reviewing your work systematically can further improve the effectiveness of your proofreading efforts.

  • Proofreading Tools: Use them, but do not depend on them entirely. Tools like grammar and spell checkers, online proofreading platforms, and readability analyzers can save time, ensure consistency, and provide valuable feedback to help you deliver polished and error-free content.

    A few options you can try are:
    • Grammarly
    • ProWritingAid
    • Ginger
    • Hemingway App
    • WhiteSmoke
    • GrammarCheck
    • and more

However, these are merely tools. Just as you cannot build a house with only a screwdriver, you cannot effectively proofread a piece using only technology. None of these will catch every single error. Even business writing contains too much nuance for a piece of software to handle. To proofread effectively, you need a human brain.

Something else to consider is which style guide your writing should be using. There are a number of style guides out there, each with their own conventions for grammar, spelling, and punctuation. Some of the most used style guides in American writing are the Associated Press Stylebook used in journalism, the Chicago Manual of Style used in the humanities and the social sciences, and the Modern Language Association Handbook in academia. In addition, your business may be using its own in-house style guide. Double-check which one you should be using, then refer to it as needed.

Assuming you have a solid foundation in grammar and spelling, here are a few more tips on how to proofread your business writing. Note that, like most aspects of the writing process, there is not one correct way to proofread. Some of these techniques may not work for you. That’s okay. As long as you check your work thoroughly, in a way that lets you find the vast majority of errors, that’s perfectly fine.

  • Take a Break After You Finish Writing and Editing: It is tempting to jump straight into proofreading as soon as you’re finished with writing and editing, especially when you’re short on time, but you shouldn’t. Here’s why: your brain will lie to you. Your piece will still be fresh on your mind, and as you read, your brain will trick you, showing you the text as you want it to be, not as it is. Let your piece sit for as long as you can. Do whatever you can to clear it from your mind in the time that you have, then come back to it with fresher eyes.

  • Go Slowly: Remember the old fable The Tortoise and the Hare as you gear up to proofread. A slow, systematic process will get you the clean copy you want. Speed will not. That means you should rely on human eyes, not tools like Grammarly or spellcheck. These can help, yes, but they cannot replace a human mind. They won’t spot everything.

    Slow. Steady. Your content and your dazzled boss will thank you.

  • Know Your Weaknesses: Is there a word that always gives you trouble? Do you know that you tend to leave out periods or have issues with commas? Are you uncertain about some information you included? Pay special attention to your weaknesses—write them down if it will help you, or make a personal style guide that tells you what you should do instead of what you shouldn’t. Whatever helps you find your weak spots and fix them, do it.

  • Read the Text in a Different Way: When it comes to spotting errors, a change in how you read can help immensely. Some options to consider:
    • Change the font, the background color, or both
    • Read it backwards
    • Read it out loud, or have your computer read it for you
    • If you’re like me and can’t stand reading writing aloud or listening to it, you’re not in a position where you can do that, or you can’t do it for any other reason, try this instead: turn on text-to-speech in Word and mute your computer, then watch closely as the computer highlights each word it reads
    • Print it out, and go over it with a red pen
    • Go over the printout with a piece of paper blocking part of the text, so you can focus on it line by line
    • Try all of the above

  • Be Sure to Check Multiple Times: The more passes you make over your document, the more chances you have of seeing your errors.

  • Ask for Help: Sometimes, another person’s eyes are better than your own. Ask a trusted colleague or friend, or even a professional, to proofread your business writing for you.
