learn how to edit your marketing copy like a professional
Most of the time if you make a typo or spelling error, the result is an embarrassment, but letting mistakes like these slip by can sometimes prove costly.

Just ask NASA.

In 1962, they were forced to explode the Mariner I space shuttle over the Atlantic Ocean. Shortly after launching the ill-fated rocket, NASA scientists realized it was on a trajectory to crash land on a populated area of Earth, all because of a missing hyphen.

Some content-related gaffs, like NASA’s, are more severe than others. That’s why you have to rely on your wits to catch red flags when editing marketing copy until tools (like spellcheck in Word and Google Docs) or free proofreading services (like Grammarly) get better at thinking critically.

You want your target audience to pay attention to the message that you’re trying to convey, not your mistakes. Keep reading to learn how to save yourself from potential proofreading horrors with our editing tips.

1. Ask questions and aim for accuracy

Does any statement in the piece you’re proofreading seem a little off or like it’s the belief of the writer? Is anything just hearsay or innuendo? Readers will find the marketing copy more trustworthy if bias is limited and your sources aren’t biased.

Remove instances of hyperbole, like “most unique” or “best ever,” but add specificity when there are broad generalizations. Infuse your writing with imagery that will resonate—authentically—with your target audience.

If the writer is not writing an opinion column, ask them to back-up any assertions with reputable references/attribution.


Phone numbers, URLs, email addresses, company names, locations—always take time to double-check crucial basic information to make sure you’ve gotten it right in the marketing copy.

Point out cherrypicking

Do any of the stats seem a little off? Does anything not ring true? If a quoted number or percentage looks too big or a statistic comes off as too unusual, ask the writer to provide sources for verification. When you’re in doubt, don’t trust your memory!

2. Go over the copy carefully—twice

Start by reading the piece as someone who might be in your target audience and consider the following questions from their point of view:
  • Is the copy engaging?
  • Are keywords added in a way that doesn’t disrupt the reader?
  • Are there places that bore you?
  • Is there any wording that trips you up or confuses you?
  • Does the copy answer a question you have?
  • Does the copy provide a solution to a pain point?
Then, it’s time to review for accuracy.

Reread the copy as an editor and look for broken links, typos, grammatical errors, brand voice/style problems, and spelling mistakes. Don’t forget to recalculate any math and double-check dates.

3. Clean-up formatting

Check for little things that the writer might have missed, like removing double-spaces between sentences. Make sure that you have a templated way to accommodate any copy that requires special formatting (e.g., tables with data).

If your copy is appearing online, remember short paragraphs, subheads, and bulleted lists (when appropriate) are a reader’s friend, especially on mobile.
Once the original, edited marketing copy makes its way into the layout, review it again to make sure any headlines, subject lines, and captions written later make sense and are error-free. Also, examine the layout to make sure all of the content didn’t go missing in the transition to design.
