Every course review on CourseSift follows the same research and verification process. This page explains what that process actually involves.
Where our facts come from
Every fact in a CourseSift review — price, duration, syllabus content, instructor credentials, certificate type, enrollment numbers, ratings — is checked directly against the course’s own official page on its platform (Coursera, edX, FutureLearn, and the others we cover) at the time of writing. We do not source pricing, syllabus content, or credentials from third-party aggregators, marketing summaries, or AI-generated guesses.
Where a detail genuinely isn’t available on the official page — a rating that isn’t displayed, a language list that’s only shown as a count — we say so directly rather than estimating or inventing a plausible-sounding number.
What “How We Reviewed This” means
Near the top of every review, you’ll find a short “How We Reviewed This” section listing exactly what was checked and how — which pages were consulted, what was cross-referenced, and what specific verification steps were taken for that course. This isn’t boilerplate; it’s specific to each review.
How we use outside sources
We do check community discussion and other independent review coverage — but only as a way to catch something our own research might have missed, never as a source we cite or copy from. Any lead surfaced this way is independently re-verified against the official course page before it appears in a review. If we can’t verify it directly, it doesn’t make it into the review.
How we handle limitations and criticism
We aim to be specific and honest about where a course falls short — a mismatched difficulty label, a syllabus that stays conceptual when it markets itself as hands-on, an instructor whose real-world experience doesn’t match the subject being taught. We frame these as questions of audience fit rather than blanket judgments: a course that’s too basic for an experienced learner might be exactly right for a complete beginner, and we try to make that distinction clear rather than simply calling a course “good” or “bad.”
Keeping reviews current
Course pricing, syllabi, and certificate structures change over time. Each review includes a “Content Last Verified” date so you know how recent our information is. If you notice something that’s changed since that date, please let us know through our Contact page — corrections are one of the highest priorities in how we maintain this site.
Editorial independence from advertising
CourseSift earns revenue through affiliate partnerships and advertising, detailed in full on our Affiliate Disclosure page. This revenue never influences which courses we choose to review or how we describe them. The verification process on this page is applied the same way regardless of whether a given course or platform has any commercial relationship with CourseSift.
