What must a counselor include in an internet advertisement?

Including the counselor's name, credentials, and license number in an internet advertisement aligns with the ethical and legal standards held by professional counseling entities. This requirement ensures that clients can verify the qualifications and legitimacy of the counselor before engaging in services. By providing the counselor's license number, it adds an additional layer of accountability, enabling potential clients to confirm the counselor's current status and credentials through state licensing boards.

Moreover, transparency in professional advertisement fosters trust between the counselor and the community, ultimately promoting ethical practice and informed client choice. While the other options touch on aspects of advertising, they do not encompass the full scope of what is necessary for a comprehensive and compliant internet advertisement. For instance, simply providing the counselor's name and credentials would lack the crucial verification aspect that comes with the inclusion of a license number.
