25 Free Search Engine Optimization Courses
Imagine you realize that it’s time to learn SEO, so you look up a course. Ten minutes later you have 3 half watched videos and a sense of frustration that all the experts on the web are against each other! Tabbed by the weekend, you know just a little.
It doesn’t mean lack of enthusiasm. Sorting problem. However, there’s no shortage of free courses on search engine optimization (SEO), which was created by the search engine’s tool makers, plugin teams, and Google itself, and no one tells you which course is right for you. We can’t all be WordPress bloggers. And, a shop owner looking to attract nearby customers needs something else than a WordPress blogger. It’s the same as an agency marketer who lives inside reports.
So this list will do the sorting. Here are 25 free SEO courses and learning resources to help you. Most of them are legitimate SEO courses and a handful are official documentation, which is not a course per se, but still serves as stellar SEO training. Each entry starts with a short details table which will let you know the platform, level, cost and certificate at a glance. If you are looking for free online courses that never require a credit card, you’ve come to the right place.
There is something for everybody. There is local SEO for businesses which depend on their local customers, technical SEO for all who want to know more about crawling and indexing, and the essentials of on page SEO and off page SEO. If you’re a numbers person, there’s keyword research and link building, content SEO and SEO analytics. There are a couple of resources out there that address Google SEO in the AI-answer era, and a few that are the brief SEO tutorial for a lunch break. All of this is part of the larger domain of internet marketing and when you’re finished with the course, many provide you with a certificate or a badge to evidence that you have gone to the effort of earning a certification.
There’s one tip: Don’t attempt to complete 25. Complete one of the beginner courses, then select a course based on your goals, such as increasing your chances of ranking high in search results, generating more constant organic traffic, or fine-tuning your SEO plan. With exception of LinkedIn Learning, which may be based on a trial or subscription. Ready? Let’s begin.
Note: Course availability, certificates, badges and paid add-ons are subject to change on these platforms very frequently. Some have no entry or exit fees. Some provide free learning content and then take payment for the exam or a hard copy certificate. Below all the entries are marked as to which is which but always checks on the platform before investing their time in it.
