The short version: HubSpot Academy, Semrush Academy, Google Skillshop and OpenLearn offer the best free digital marketing courses in 2026, and HubSpot and Semrush give you a certificate at the end. HubSpot's free certifications take between three and eight hours each, and its exams have a strict timer.
Digital marketing is one of those skills where the free training is as good as most of what's on offer. The platforms want you to learn their way of doing things, so they invest in clear courses and recognised badges. For a small business owner or someone switching careers, that's a great opportunity. The trick is choosing courses that teach the job, not just the software.
Five places to learn digital marketing
In no particular order:
- HubSpot Academy: best for inbound, content, social media and email marketing certifications.
- Semrush Academy: best for SEO, content and competitor research skills.
- Google Skillshop: best for Google Ads and other Google product certifications at your own pace.
- OpenLearn: best for broader business and marketing theory from the Open University.
- Meta's learning hub: best for Facebook and Instagram advertising know-how from the source.

What each course covers
HubSpot Academy says you can grow your career and your business by completing free certifications and adding recognised badges to your LinkedIn profile. The list shows how long each one takes: Digital Marketing and Inbound are about three hours, Digital Advertising four hours, Social Media Marketing five hours and Content Marketing eight hours. There's also a short course on using HubSpot's free marketing tools, which takes about an hour.
Semrush Academy describes itself as a place to learn marketing for free with online courses, and you can get a certificate from it. The courses lean towards SEO and content, taught by practitioners, so they suit anyone who writes for a website or manages a blog. Google Skillshop lets you learn at your own pace and get Google product certified, including Google Ads.
OpenLearn courses are free, available immediately and have no start or end date. If you sign up, you can track your progress and work towards a statement of participation. It's less badge-focused and more about understanding why marketing works.
The HubSpot exam rule that catches people out
Here's the detail people only find after failing. HubSpot's FAQ says you have three hours to complete an exam. You can navigate away, but if you don't return and finish within three hours, you'll fail and get a notification. HubSpot suggests blocking off the time and taking the exam in one sitting.
If you do fail, you can retake the exam once it opens again after 12 hours, and HubSpot says it can't open it early. Afterwards it emails a breakdown of the questions you got right and wrong, grouped rather than in exam order, but it won't share the answers. And if a certification has practical exercises, your exam results last as long as the badge does, so finish the exercises before the results expire.
So don't start a certification exam on your lunch break between meetings. Clear an evening, close your email and do it in one go.
How to get the most from free courses
- Choose one skill you need now, such as SEO, email or social media.
- Start with the matching HubSpot or Semrush course and block time in your calendar.
- Take notes you'll use, such as a checklist for your own website or social channels.
- Book the exam for a quiet window of at least three hours.
- Apply what you learned to one real campaign before starting the next course.
- Add the certificate to your LinkedIn profile and mention what you did with it.
Choosing between the courses
If you only have time for one, match it to the channel that brings you the most customers. Most of your leads come from Google? Start with Semrush for SEO, then Skillshop if you run ads. Your business lives on social media? HubSpot's Social Media Marketing certification is the better first step. If you're building an email list, HubSpot's inbound and content courses explain how the pieces connect. OpenLearn is the one to choose when you want the thinking behind the tactics rather than a badge. Whatever you pick, avoid stacking five courses at once. One finished course that changed how you run a campaign is worth more than five half-watched ones sitting in your account.

Putting your new skills to work
Certificates help, but results help more. If you use HubSpot, my HubSpot marketing strategy guide shows how the theory turns into a plan. Thinking about deeper copywriting training later? Read how to choose a copywriting course first. For wider options, here are some Coursera alternatives.
My verdict: start with HubSpot's Digital Marketing certification for the big picture and Semrush for SEO, then use Skillshop if you run Google Ads. Do them in one sitting, and use each lesson on your own business the same week.
