As a result, you now have a more specific audience, but your ads will naturally be usa phone number data shown much less frequently than with pure broad match. Conversely, this can of course mean that restricting the keyword may mean you're no longer shown for relevant searches.

In practice, a combination of both options is best. For example, multiple main keywords can be specified. This would be +red +hiking boots, for example. Therefore, both words must be explicitly included in the search.

Unfortunately, there are limits to these combinations. If you choose combinations that are too specific, the search volume will be extremely low, and your ad will barely be displayed or not displayed at all. AdWords will then immediately point out the pointlessness of your target audience. In this case, you're forced to target broader audiences. This can also be problematic in countries with smaller populations. The more specific you are, the less of the target audience remains.
