Evaluating the effectiveness of ads is critical for gauging the impact that they've had on sales & awareness. Here's the equation for calculating this out:

Advertising campaign effectiveness = Revenue + Return on investment (ROI)

There are various ways to measure the effectiveness of advertising campaigns:
- Conducting a survey is a good idea so we can see how the campaign went and what people took away from it.
- The uptick in sales for that product/service
- More customers are calling your toll-free and marketed lines.
- Redemption of coupons and vouchers
- Increased footfalls in the store to purchase product
- Increased traffic on the company’s website.

It depends on the following factors:

- Reach
- Geographical spread
- Nature of target audience/clusters
- Previous successful track records
- Low budget; high returns etc

- Billboard advertising.
- Point of sale advertising.
- Retail advertising.
- Vehicle advertising.
- Construction advertising

Billboards offer long-term advertising for companies. They stay in place for a long time and can be found at easily-accessible locations such as city centers, shopping outlets etc. The advertisement you posted catches the attention of people who take that route or road every day.

It’s crucial for your ads to be visible if you want results. It may also be worth thinking about where a younger audience is likely to go out, like local bars and cinemas, when planning where you will do the most advertising.
