How CoursesGlobal compares courses

We list 1,071 online courses from 10 providers across 169 topics, last verified on 8 November 2026. This page explains exactly where every number comes from, so you can check us.

Where the data comes from

Every price, rating, duration, level and certificate flag on this site is read from the provider's own course page — the same page you land on when you click through. We never estimate a figure. If a provider does not publish something, we leave it blank rather than fill it in.

We read the structured data providers publish for search engines first, then their page markup. Each course record stores when it was last checked, and that date is shown on the page.

Courses currently listed come from:

  • Udemy — 704 courses
  • Coursera — 249 courses
  • Codecademy — 49 courses
  • edX — 28 courses
  • Udacity — 14 courses
  • Niit — 10 courses
  • Scaler — 8 courses
  • Market Tutorialspoint — 6 courses
  • freeCodeCamp — 2 courses
  • upGrad — 1 course

How we order what you see

The default order is not "highest rating". A 4.9 from 12 ratings tells you very little, so we weight a course's rating by how many people rated it, then adjust for how many learners it has, whether it includes a certificate or placement support, and price. You can override this at any time with the sort control — rating, price or newest — and that ordering is exactly what it says.

Paying us does not move a course up. No provider can buy a position, a rating or a "best" label.

Our review policy

We do not publish our own learner reviews, and we do not write them. Where you see a rating on this site, it was collected by the provider from its own enrolled learners, and we say so and link to it. We reproduce it as reported.

Because those ratings are not ours, we deliberately do not mark them up as our own review data for search engines. If we ever collect first-party reviews from learners here, they will be clearly labelled as such and will be the only reviews we mark up.

We do not accept payment for a review, a rating or a recommendation.

How this site is funded

Some enrolment links on this site are affiliate links: if you buy a course after clicking one, we may earn a commission at no extra cost to you. That commission is how the site is funded. It does not affect which courses we list, how we rank them, or what we say about them — including when we tell you a course is not worth paying for, or that the free option is enough.

Who writes this

Pages are compiled by the CoursesGlobal editorial desk from the catalogue data described above. Comparisons, decision guidance and FAQs are written against that data and checked against it before publishing — a claim that cannot be traced to a provider's own page does not go live.

Course pages are re-checked as prices and ratings change. Found something wrong? Tell us and we will fix it.

What we do not do

  • We do not invent prices, ratings, salaries or learner counts.
  • We do not publish reviews we did not collect.
  • We do not copy a provider's course description — we summarise and link to the source.
  • We do not publish a comparison page with nothing to compare on it.
