Overview
CertWorthIt is a data-driven research platform that counts how often employers name specific certifications in real job advertisements. It queries the Adzuna job-ad API across ten countries and applies AI-assisted analysis to credentials such as PMP, CCNA, CompTIA A+, CISSP and AWS, alongside the skills requested in the same postings. The dataset spans 362,748 ads and 78 certifications, with each figure linked to its source. The audience is candidates, career switchers and training providers seeking evidence over marketing claims.
Key Features
- Job-ad mention rates: For every tracked certificate the platform publishes the share of matching job ads naming it — PMP appears in 24% of United States project manager ads, while OSCP reaches 73% in its field.
- Certification versus skill comparisons: Industry certifications, course certificates (Google, IBM) and plain skills sit side by side in the same chart, exposing gaps such as SQL at 42% of data analyst ads against 7 of 6,094 ads naming Google Data Analytics.
- Country coverage: Ten markets — United States, United Kingdom, India, Brazil, Mexico, Spain, France, Germany, Italy and Poland — can be compared, with a ranking of the most-named certification per country.
- Field and role browsing: Certificates are grouped into Cloud & DevOps, Cybersecurity, Data & Analytics, IT Support & Networking, Project Management, AI and Agile & Scrum, and reachable from job titles like data engineer, network engineer or SOC analyst.
- Head-to-head comparisons: Dedicated pages contrast CAPM vs PMP, CCNA vs CCNP, CISSP vs OSCP and CSM vs PSM using ad-share figures.
- Search and quiz: A live search index covers certificates and jobs, plus a four-question quiz that maps a job goal to relevant credentials.
- Methodology transparency: Counts originate from the Adzuna API, figures link to their sources, and a published methodology page explains the counting rules.
- Email reports and newsletter: Country-level reports and monthly updates tracking which certifications gained or lost ground.
