C4D writers and editors generally follow AP style. The following guidelines take precedence if they differ from AP style. Client editorial style guides and preferences take precedence. Use Webster’s New World College Dictionary for spelling of words not included in these style guides: http://www.yourdictionary.com/dictionary-definitions/
All client-facing content, including interview questions, outlines and drafts, should use clear and consistent formatting:
In a series of three or more, do not use a comma before the final "and" unless required for clarity.
Example: The company offers loyal customers special deals, discounts and coupons.
Example: The company offers loyal customers special deals, discounts, and coupons or cash-back offers.
Use periods at the end of complete sentences; otherwise, no punctuation at the end of a bullet point. (Note that imperative sentences such as “Forge alliances within the C-suite are indeed complete sentences.)
Use numerals rather than spelling out numbers.
Always use numeras folr percentages and decimal-point numbers, and use a percent sign for percentages (e.g. 150%)
Write out the months March, April, May, June and July.
Use three-letter abbreviations for all other months.
Use the time-date-place rule (e.g. "The holiday sale will begin at midnight on Nov. 25, 2011, at the Garden State Park Mall.")
Reserve the use of ampersands (&) only for headlines and subheads, and even then try to avoid using them if possible. Never use ampersands in body text unless it is part of a company name (e.g. Dun & Bradstreet)
Dashes in sentences should use em dashes with one space before and after.
Avoid using passive voice whenever possible. Writers and editors should know the difference between active and passive voice.
When referring to businesses or other organizations, refer to them in third-person singular ("it" "its") rather than plural ("they" "their"), and try in general to minimize this usage.
Refer to quarterly results as Q1, Q2, etc. and fiscal years as "FY."
Headlines and subheads should use initial caps (lowercase articles) and bold type (e.g., This Is a Good Subhead).
Avoid using "we" when describing the contents of a content asset. Find a more active way to summarize or describe the content. Exception: May be appropriate when client wants to impart their strong POV.
Avoid beginning sentences with prepositions unless they are part of a direct quote.
It is acceptable, within reason, to correct grammar errors in direct quotes. Always use your best judgment in such matters.
Double-check business names and individual names/job titles.
Use "more than" instead of "over" when referring to numbers or percentages.
Avoid using URLs in copy unless it makes sense. Use links instead.
