I get that this can be a little hard to understand with all the buzzwords, so I made a glossary:

Advice: tips coming from my expertise as a professional, I have 10+ years experience working in marketing communications for a wide variety of cultural, commercial and media brands. Six years of which as head of the marketing communications department, being part of the management team and end responsible for department targets, budget and strategy.

Brand: depending on your industry either your product, service or personality.

Communications: defining, creating and distributing any type of internal or external message and tone-of-voice for your brand. Free/paid press and PR are part of communications, the default is often B2C (business to consumer) but B2B (business to business) can be part of this too. Being and/or supporting the brands spokesperson(s) belongs here as well.

Data: collecting and/or working with data that can be used to produce insights, analysis and/or recommendations for your brand. This can be done with a variety of tools, like Google Analytics, Python or SQL.

Marketing: selling your brand to a defined target audience through a mix of off- and online platforms. You can do so with content and ads. Some people call that storytelling. Don't buy that, that's meta-marketing.

Partnerships: deals between brands to create exposure and reach new audiences that suit both brands needs.

Strategy: a plan to achieve a (long-term) goal. More info here.

Team/personal management: end responsible for anything department related and in charge of managing teams as a whole and on an individual level: creating team (member) objectives, hiring new team members, day to day management, personal growth, defining and managing workload.

Workplace: the environment in which you work. Even though that's probably mostly from home now in stead of an actual office, there's still an office workplace eco-system in place that you're part of.
