Make an effective online advertising campaign

Set your business goal.
It could be anything from educating your customers about an existing product to launching a new product.

Decide on the number one message you want to convey in the advertising campaign and what action you want to take.
For example, your message could be that your product is the current most effective recent weight-loss product in the market, while your most desired response could be for your clients to place their orders online.

State the value of the product or service you are advertising
For example, the product could guarantee improved sleep for all people who have insomnia.

Choose your Key Performer Indicator (KPI).
For example, your KPI could be the number of emails delivered or opened.

Choose the forms of online marketing you want to do.
For example, is it Google Ads, Facebook ads, or Instagram ads?

Go slowly
Spend a little money to experiment with your ad and play around with the options available to you.

Monitor the effectiveness of your experiments and focus on running your ads on the more effective platforms.
