Power BI Essential Training
Per-criterion
Twelve marketing disciplines — market research, WordPress, email, copywriting, SEO, YouTube, social media, Facebook Ads, Google Ads, Google Analytics, LinkedIn and app marketing — are packed into 23 hours across 246 lectures. For a beginner, that map is genuinely useful and coherently organised. The clear deduction is the Google Analytics module, which was built on Universal Analytics before Google retired it in July 2023; learners in 2026 must supplement it independently for GA4. The SEO section is also criticised for spending fewer than 20 minutes on backlinks and omitting standard tools like Ahrefs and Screaming Frog.
Daragh Walsh is the reviewer favourite — analytical, clear, operator-first — while Rob Percival's Codestars brand (2 million+ students on Udemy) supplies the reputational weight. Criticisms are almost entirely about course scope and currency rather than delivery quality. Walsh's responsive Q&A is cited positively by multiple independent sources, and the teaching pace is described as accessible without being condescending.
At the near-permanent Udemy sale price of $11.99–$14.99, twelve marketing channels with lifetime access and 246 lectures is hard to beat. Multiple reviewers reach for hyperbole — "I feel like I robbed a bank" — and even critics concede the breadth-to-cost ratio is exceptional. At the $89.99 list price the calculus is tighter, but that price is effectively fictitious; the sale is almost always on.
Reviewers consistently describe the course as useful for understanding how the channels fit together and for holding your own in a junior interview or freelance pitch. The recurring gap is between course completion and independently running campaigns that generate revenue. YourDigitalAid's reviewer frames it directly: the course equips you with enough to pass an interview but not enough to run paid campaigns unsupported. Small-business owners report the most actionable carry-over; specialists report the least.
Daragh Walsh's Q&A responsiveness is cited positively in multiple reviews and aggregator profiles. Being on Udemy means there is no cohort, no coaching, and no live community — the support experience is async Q&A plus the broader Udemy discussion threads. For a self-paced course at this price point, the instructor engagement is above average for the platform.
Solid coverage of the Power BI Desktop surface — Get Data, Power Query, basic modelling, intro DAX, visuals and publishing. Depth stops short of advanced DAX, row-level security and deployment pipelines.
Gini von Courter is one of LinkedIn Learning's most prolific Microsoft instructors with 250+ courses across Office, SharePoint and Power Platform. Reviewers describe her delivery as calm, methodical and enterprise-friendly.
Included in the LinkedIn Learning subscription (~$40/month) and bundled with LinkedIn Premium. HN commenters repeatedly flag US public-library access as the cheapest path. Power BI Desktop itself is free.
Coherent walkthrough of the everyday workflow — connect, shape in Power Query, model, write basic DAX, build visuals, publish. Stops short of advanced DAX, time intelligence and dataflows.
Power BI is the dominant BI tool in Microsoft-heavy enterprises and the common next step after Excel for finance, ops and analyst roles. Maps cleanly onto what a junior analyst builds week one.
