What is an advertising campaign?

An advertising campaign is best defined as a coordinated series of advertisements that share a common theme. This approach allows businesses to convey a unified message and strengthen brand recognition over time. By ensuring that each advertisement within the campaign aligns with the overall strategy, the business can effectively reach its target audience and create a lasting impression.

A coordinated series of advertisements is crucial because it establishes a narrative or a clear message that resonates with consumers. This consistency across various platforms enhances the campaign's effectiveness, as it reinforces the same idea, tone, and visual cues, creating a more cohesive experience for the audience.

In contrast, other options fail to capture the essence of an advertising campaign. Independent advertisements lack coherence and can lead to mixed messages, while a random selection of promotional strategies would not optimize the impact or clarity needed for effective communication. A singular advertisement, although it can be effective, does not leverage the power of repetition and variety found in a well-structured campaign. Thus, the coordinated approach exemplified in the correct answer is fundamental for achieving advertising goals.
