The first thing you will need to do is search for keywords that will trigger your ads to appear. Keep in mind that your keywords should be relevant to your business. For instance, if you offer cleaning services, a relevant keyword would be 'house cleaning.' Of course, your keywords should also be exhaustive. Don't just stick to the generic keywords that get tons of searches every month. Place focus on long-tail keywords. These are less common than their generic counterparts, but they're also less expensive and more specific. People who use long-tail keywords to search already know what they want. Therefore, they offer a higher conversion value.
