We create digital sign advertisements to touch customers and deliver rich information. A good digital sign plan needs a clear call-to-action and unique advertising slogans to stand out from competitors. This task puts huge pressure on design workers. However, a single careless grammar mistake can waste all your hard work and ruin your previous efforts and brand reputation. To leave a positive impression on customers, you must check your digital sign plans repeatedly and avoid the following common mistakes.
In the display rack industry, we never allow such problems to appear on our products, whether on digital signs or printed display rack content. We triple-confirm all icons, logos and copy with clients before starting printing and production. On some occasions, clients may overlook potential errors. We spot these risks with our professional experience, give friendly reminders, and work with clients to find suitable solutions.
1. Incorrect Use of Punctuation
Punctuation plays a vital role in digital sign copy. It not only divides sentences properly but also prevents readers from misunderstanding your message. In fact, correct punctuation can determine the success or failure of your advertising copy.
The most common punctuation error is missing a comma after introductory clauses or phrases, especially when you deliver short and clear messages to the public. Take the sentence “You know I do not know” as an example. Without proper punctuation, it has completely different meanings.
First, it can mean “You know, but I do not know”. Second, it can mean “Do you know? I do not know”. Third, it can mean “Do you know me? I do not know.”
Wrong or missing punctuation will make readers totally misunderstand your original intention. You should add a punctuation mark whenever you need a pause or feel unsure about the expression in your copy.
2. Improper Use of Internet Slang and Abbreviations
With the popularity of various social apps, people get used to replacing standard words with letter abbreviations and internet slang in daily chats. We use these casual words when chatting with friends, recalling old days with classmates or joking with partners. For example, people use “u” instead of “you”, “OK” instead of “all right”, and “thx” or “3Q” instead of “thank you”. We also widely use abbreviations like OMG and BRB in daily communication.
These informal expressions are common in personal chats, but they are totally unsuitable for pay-per-click advertisements. They look very unprofessional and cannot serve global audiences, so you must never use them in formal digital sign designs.
3. Misuse of Homophones
Homophones are words that share the same pronunciation but have different spellings and meanings. Many people judge words by their sounds, so they easily mix up homophones. This mistake will cause awkward and embarrassing problems in your advertising copy.
Everyone can make grammar mistakes, even in formal writing. However, if you fully learn and understand these common errors, you can effectively avoid them in your digital sign design work. This rule is especially important for the display rack industry. We must stay away from all the above mistakes in both digital sign content and printed display rack copy. Small errors in punctuation, word choice and writing style will hurt the brand image and reduce customer trust. Therefore, careful checking and standard writing are necessary for every project.
