You should choose specific google adwords keywords that are directly related to the topic of your ad if you want to target customers who may be interested in a particular product instead of pointing to irrelevant topics.
Using more specific keywords means that your ad only appears for terms that apply to your business.
One thing you have to keep in mind is that if the keywords are too specific, you may not be able to reach as many people as you would like.

We recommend using 5 – 20 keywords per ad group. However, you can have more than 20 keywords in an ad group if you want. Remember, each ad group needs to contain keywords that are directly related to that group's topic. Your google keywords will automatically match for variations such as possible misspellings or plural versions.
