CertWorthIt is a job-ad data site that answers whether a given certification is worth pursuing by counting how often employers name it in real job postings. It ingests job ads from the Adzuna API, uses AI to analyze the data and write its pages and reports, and links every published figure back to its source.
What is CertWorthIt?
CertWorthIt is a certification-research tool that counts how often employers name a specific certification, course certificate, or skill in job ads. It takes Adzuna job-ad listings as input and outputs per-certificate and per-role share figures, comparison charts, and country-level email reports. It runs as a website, and its pages and reports are written by AI over the counted ad data.
What makes CertWorthIt stand out?
- Job-ad share counts, not opinions — each figure is the share of matching job ads that name an item, e.g. PMP appears in 24% of US project manager ads.
- Three-way comparison per role — every tracked job shows an industry certification, a course certificate, and a top skill side by side.
- Source-linked figures — the site states that every figure links to its source, with counts drawn from the Adzuna API.
- Scale of data — 411,984 job ads counted across 10 countries and 105 certifications with job-ad data, dated October 2026.
- Certificate lookup — a search box checks a certificate or job, with a 4-question quiz and an A–Z certificate index as fallbacks.
- Field browsing — certifications grouped into eight fields, including Cloud & DevOps (26 certifications), Cybersecurity (16), Business/HR/marketing (14), AI (13), and Data & analytics (12).
- Country reports by email — a report for the selected country is sent once, with no repeat mailings.
- Optional personalization — two optional questions (experience level and goal) shape the first step of the report without requiring an email.
Who should use CertWorthIt?
- Career switchers — people moving into IT or data who need to know which certification employers actually name before paying for training.
- Early-career job seekers — candidates deciding between an industry certification and a course certificate for a first role.
- Experienced professionals — practitioners with 3+ years in the field weighing a certification for a promotion.
- Data and IT analysts — anyone comparing named certifications against the skills the same ads request, such as SQL at 42% of data analyst ads.
