First, make sure you know who your product and or service is for(customer persona).

Next, segment the data according to your prospect information.

After, Create exciting AD's to capture their attention (you can do a small ad test and split test the ad to make sure it's useful.)

Have the add lead to more information and then into a buy!

Capture abandon services, then target with a different ad.

Remember, you always want to provide them value in your service, so make it about their needs not what you think they need.(this requires you understanding your customer)

If all this is too much, you can always create a simple AD dependent on what you want to accomplish and push that.
