A call-to-action (CTA) is the word or set of words that tells the user what to do next, whether you're trying to provide them with more information on a certain topic or get them to sign up for a program. We have different rules for what type of CTA is used for each page type. Visit our CTA Guidelines to get more information on what CTAs are used where.

Avoid using generic CTAs like "Learn more" or "Get Started" and have more specific, creative CTAS like "Energize your future" or "Start saving now." CTAs are written in sentence case, except for in-campaign pages that use Arvey. In that case, CTAs should use title case.

On XcelEnergy.com, we do not use parentheses or dots in phone numbers. We use dashes to ensure dialing functionality and readability. Do not include a 1 in front of the area code. This also applies to toll-free area codes such as 800, 877, 855, ect.

With these guidelines, our Customer Service number would be written: 800-895-4999.

When referring to a house or property, always use premises, even if it isn't plural.

Example: I visited the premises in the morning, and then I visited multiple premises in the afternoon.

Using the word premise will almost never be used on XcelEnergy.com. Premise is defined as a statement or idea that is accepted as being true that that is used on the basis of an argument.

Nonprofit is one word and does not require a hyphen. However, should you choose to write not-for-profit, hyphens are justified in that instance.

Sign-up is a noun, and sign up is a verb. In a CTA, we want users to take action, so sign up would be the correct term.

Example: Sign up for the conference by attending the sign-up event.

To improve readability and consistency with graphics, content should use the percent sign over writing out percent.

Example: By 2021, 70% of your energy will come from renewable sources.
