Do Online Certifications Actually Matter?

The value of an online certificate depends almost entirely on which certificate you earn and how you use it. A well-recognised credential from a reputable issuer, paired with a strong portfolio and clear communication of your skills, can genuinely advance your career. Here are five that stand out.

1. AWS Certified Cloud Practitioner

Amazon Web Services dominates the cloud market, and this foundational certification is widely recognised across industries. It demonstrates a solid understanding of cloud concepts, AWS services, and basic security and architecture principles. It's a strong entry point for a career pivot into tech or a stepping stone to more advanced AWS certifications.

How to Make the Most of Any Certification

A certificate alone won't transform your career. To maximise the value of any credential:

  • Add it to your LinkedIn profile and resume with a clear description of what it covers.
  • Build a project or portfolio piece that demonstrates the skills in practice.
  • Talk about it in interviews by explaining why you chose it and what you learned.
  • Continue learning — certifications are a starting point, not a finish line.
