Final answer:
It is generally advisable to avoid unnecessary or improper use of symbols in AdWords as they can have special meanings, could be misleading, or could lead to ad disapprovals if not used correctly.
Step-by-step explanation:
The statement "symbols have special meanings in AdWords, so you should generally avoid using them" addresses the use of symbols within AdWords , an online advertising platform. In the context of the platform, certain symbols can indeed have specific functions or cause errors if used improperly. For example, using quotation marks can signal a phrase match, while a plus sign before a keyword can modify a broad match. However, using symbols inappropriately can result in ads not displaying correctly or failing to trigger the desired action. It is, therefore, generally good practice to be cautious of symbol use in ad text unless you are using them for their predefined functions within the Ads system.
Additionally, has strict ad policies on the use of symbols that are misleading or irrelevant in an attempt to draw attention, such as excessive punctuation or non-standard symbols. Misuse of symbols can lead to ad disapprovals. Thus, while it is not entirely true that you must always avoid using symbols, as their appropriate use can be beneficial, it is crucial to understand their specific use cases and the guidelines imposed to ensure that your ads run effectively and reach the intended audience.
