Certifications and IT: Boosting Credibility and Earnings
IT certifications are a proven way to increase employability and salary. Several Udemy most popular courses are designed specifically to prepare learners for industry-recognized exams:
- CompTIA A+ Certification (Core 1 & Core 2) by Andrew Ramdayal (40 hours, $19.99 sale) – Covers hardware, networking, and security fundamentals. Ideal for entry-level IT support roles.
- Cisco CCNA 200-301 Complete Course by David Bombal (50 hours, $19.99 sale) – Prepares students for the CCNA exam, a gateway to network engineering careers.
- Google IT Support Professional Certificate (offered via Coursera but mirrored on Udemy in similar form) – While not on Udemy directly, many learners supplement with Udemy’s IT Support courses.
These certifications can lead to roles such as IT Technician, Network Administrator, or Systems Analyst. The CompTIA A+ alone can increase starting salaries by $10,000–$15,000. Udemy courses in this category often include practice exams, lab simulations, and exam voucher discounts. Difficulty ranges from beginner (A+) to advanced (CCNA), but most include step-by-step labs and real-world troubleshooting scenarios.
Business, Productivity, and Soft Skills
Not all Udemy most popular courses are technical. Many top performers focus on business acumen, leadership, and productivity—skills that complement technical expertise and enhance career mobility:
- Communication Skills for Beginners by TJ Walker (5 hours, $12.99 sale) – Focuses on public speaking, body language, and confidence building.

These courses are particularly valuable for mid-career professionals aiming for leadership roles. While they don’t lead to formal certifications, they enhance performance reviews, client interactions, and promotion potential. Many are completed in under 10 hours, making them ideal for busy professionals.
Career Outcomes and Return on Investment (ROI)
One of the most compelling aspects of the Udemy most popular courses is their high return on investment. Most top courses cost under $20 on sale—often less than the price of a textbook—and take 10–60 hours to complete. Compare this to traditional bootcamps ($10,000–$20,000) or college degrees, and the value proposition is clear.
According to Udemy’s internal data, 40% of learners report career benefits such as:
- Landing a new job (22%)
- Getting a promotion (14%)
- Starting a freelance business (8%)
- Increasing salary by 10–30% (18%)
For example, a student who spends $15 on the AWS Solutions Architect course and passes the $150 certification exam could see a salary bump from $70,000 to $90,000—representing a ROI of over 10,000% in the first year alone. Similarly, completing the Web Developer Bootcamp and landing a $75,000 job after previously earning $40,000 results in a $35,000 annual gain, far outweighing the course cost.
However, ROI depends on completion and application. Passive viewing yields minimal results. Successful learners treat Udemy courses like bootcamps: they code daily, build portfolios, and apply skills in real projects or freelance gigs. The most effective strategy is to pair a technical course with a soft skills course—e.g., learning Python while improving communication—to become a well-rounded candidate.
