A solid link-building service essentially takes that entire burden off your shoulders. They can handle research, strategy, execution, and tracking, so you don't have to spend weeks figuring out which flavor of links works best for your niche.
The key is finding a service that's flexible and transparent—they should be able to adapt to your goals and show you what they're doing ever.
