An advertising strategy is a plan of action that outlines how an advertiser will reach their target audience with their advertising message. It involves identifying the target audience, determining the key message or value proposition that will resonate with them, and developing a plan for delivering that message through various advertising channels.

The main components of an advertising strategy typically include:

1. Audience identification: This involves researching and identifying the characteristics and behaviors of the target audience, such as age, gender, income, interests, and purchasing habits.
   
   
2. Objectives: This outlines the goals of the advertising campaign, such as increasing brand awareness, driving sales, or promoting a new product or service.
   
   
3. Key message: This identifies the core message or value proposition that the advertising campaign will communicate to the target audience.
   
   
4. Channel selection: This involves selecting the most effective advertising channels for reaching the target audience, such as television, radio, print, online, or social media.
   
   
5. Budget: This outlines the budget for the advertising campaign, including how much will be allocated to each advertising channel.
   
   
6. Measurement: This involves identifying how the effectiveness of the advertising campaign will be measured, such as through sales data, website traffic, or brand awareness surveys.
   

Overall, an effective advertising strategy is critical for ensuring that the advertising campaign reaches the right audience with the right message through the most effective channels, and that the campaign is able to achieve its desired objectives.
