The answer to this question depends on two factors:
- how clear and easy-to-follow the strategy you want to implement is
- what digital marketing skills (and general capacity) your in-house team members have.
If you have an easy-to-follow, step-by-step digital marketing strategy AND your team members have the knowledge and time to execute it, implementation should be easy. Simply follow the steps laid out in the strategy.
If not, however, you might well benefit from asking a specialist digital marketing agency to step in.
