There are amazing growth chances in Digital Marketing today. It was kind of limited to SEO and SEM till a few years ago but now things have taken a different shape altogether. There are 6-7 major segments one could dwell in:
- Organic Search Optimization
- Paid Search & Display Marketing
- Social Media Marketing & Management
- Email & Newsletter Marketing
- Digital Analytics and Tracking
- Content Marketing
- Direct Email Marketing
Each of the segments above is a major one and there is an ocean of learning and growth corresponding to each one.Developing core skills in any of these can get you significant career growth. I feel Digital Marketing is becoming more niche where companies and customers are more interested in specialists in particular segments.
When something starts going niche, you know it's growing fast and you would want to tap into any one area that interests you the most and try and master it.
So, yes, lots of growth and opportunities
