While our marketers don’t specialize in any particular industry/niche, they are experts in digital marketing. They have experience with digital marketing in a wide variety of industries. In addition, many services include some research to start to make sure the worker is informed about your client's particular industry.
For many, this approach works well. However, if your client requires their deliverables to be very technical or in-depth, this might not be the best fit for them. We would recommend you and your clients evaluate your own needs to decide the best route.
