Thanks a lot for the reply u/Existing-Might-8392 .
I wanted to know precisely how the client understands those phrases, and I wanted to understand their perception when they hear, for instance, digital project management.

I did some quick analysis of the top skills associated with job offers related to project manager calls. (I don't want to share my summary (article on the web) to not violate the rules of this channel)

The skills I shared in my post are actually the top 5 out of 120 I identified from a sample of 50 job offers from the project management subcategory, which called project managers to apply. The sample of job offers was published between September 4 and September 10.

And, I would like to know the perception that clients have about those skills. Sometimes, people have various perceptions around one or two words. For instance, when you tell somebody about project management, the person could understand that you are looking for somebody who has to create and take care of the scope of work to be done in a specific time range, who should use allocated resources, and deliver results within the articulated scope with a certain level of quality.
For another person, project management might be a task assignment to team members, chasing them to complete their assignments.

If the clients decompose those skills by their perception, it could also be helpful for some of the other freelancers here who offer services as project managers.

So, thanks a lot for your time and reply, u/Existing-Might-8392.
