Where to start as a beginner
Start at the source: Google. The Google Search Central SEO starter guide is free, available in English, and updated regularly. It is the only documentation written directly by the search engine you are trying to understand. No paid course replaces this foundational reading.
The beginner's instinct is to look for tricks. SEO has none. It has principles: a fast site, accessible to crawlers, clearly structured, that answers a search intent better than the others. Everything else flows from that.
The three starting resources
Three sources cover the essentials without costing a euro. The Google Search Central guide for the rules of the game. Google's Fundamentals of Digital Marketing course from Google Digital Workshop, certified and free, for the marketing context. And the Moz glossary or the Ahrefs Academy guides for the vocabulary, indispensable when you read the rest.
Once these foundations are in place, our dedicated guide on learning SEO details the method step by step, from the initial audit to the first results. It is the logical continuation of this first phase.
Intermediate level: moving to practice
At this stage, you know the vocabulary and the principles. Now you need to produce and measure. The practice focuses on three areas: keyword research, on-page optimization, and creating content that genuinely answers an intent.
Keyword research can be learned for free with Google Trends, autocomplete suggestions, and the "People also ask" section of the SERPs. These three sources, cross-referenced, reveal the real vocabulary of your audience without a subscription to a paid tool.
On-page optimization and content
On-page optimization fits into a checklist. Here is the order of priority for a page you publish today.
Identify the target query and the intent behind it. A page answers one main intent, not five different topics.
Place the keyword in the title, near the start if possible. The meta description does not weigh in ranking but influences click-through rate.
A single H1, an H2/H3 hierarchy with no skipped levels. Each section answers a specific sub-question.
Open each section with a clear answer in one or two sentences. This habit serves the reader, Google, and generative engines.
Link each new page to two or three relevant pages on the site, with descriptive anchors.
This is also the time to learn to read your data. Search Console shows you the queries that bring you traffic, your average positions, and your click-through rates. Cross-reference these figures with Google Analytics and you have a free learning dashboard, fed by your own site.
92% of citations in AI Overviews come from the top 10 of classic results, including 47% from positions 5 to 10. In other words, traditional SEO remains the foundation: ranking well on Google also conditions your presence in AI-generated answers.
Advanced level: technical and data
The advanced level plays out on three fronts: technical SEO, log analysis, and understanding rendering. This is where free resources become rarer but more valuable.
The Google Search Central documentation offers a complete developer section: JavaScript rendering, structured data, crawl budget, canonical tags. Read it in full. It is dense, it is free, and it is first-hand truth. Bing Webmaster Guidelines usefully rounds out the picture by covering a second search engine.
JavaScript rendering, a critical blind spot
One technical topic deserves particular attention in 2026: rendering.
For data analysis, Google Search Console is more than enough at the advanced level: explore the API, export your data, cross-reference queries by page group. The technical guides from Ahrefs and Sistrix, freely available on their blogs, explain how to interpret these signals without owning the paid tool.
This is also the level where GEO becomes essential. Generative search is changing the rules, and our resource on training in GEO covers this transition in detail. A serious SEO agency no longer separates the two disciplines.
The free tools worth a full course
The best free tools are training in disguise. They force you to understand the concepts in order to interpret their data. Here is the honest comparison between free and paid versions.
| Need | Free solution | When to go paid |
|---|---|---|
| Performance tracking | Google Search Console (unlimited) | Never, it's the reference |
| Technical audit | Ahrefs Webmaster Tools (verified sites) | Several client sites to audit |
| Keyword research | Google Trends + autocomplete + PAA | Precise, large-scale search volume |
| Competitor analysis | Limited free versions of Semrush, Ubersuggest | Daily competitive monitoring |
| Site crawl | Screaming Frog (up to 500 URLs) | Sites with more than 500 pages |
Ahrefs Webmaster Tools deserves a special mention. Free for sites whose ownership you can prove, it offers a technical audit, backlink tracking, and ranked keywords. For a beginner as much as an intermediate, it is an entire school.
The tools that train you in GEO
The new generation of tools integrates visibility in generative engines. Monitor your brand mentions, not just your ranking. An Ahrefs analysis of 200,000 domains, published in December 2025, shows that off-site brand mentions correlate more strongly with AI citations (YouTube at 0.737, Wikipedia accounting for 47.9% of ChatGPT citations) than Domain Rating, whose correlation only reaches 0.266. The lesson for anyone learning today: work on your off-site presence as much as your site.
Building your learning path
Free SEO training is only worth what its structure makes it. Stacking up resources with no order is the surest way to give up. Follow a progression and set yourself a concrete goal: get a page to rank for a specific query.
The right order is simple. Month one: fundamentals and vocabulary, reading the Google guide, practicing on a test site. Month two: keyword research, on-page optimization, daily reading of Search Console. Month three and beyond: technical, data, and integrating GEO. Don't skip steps: you can't understand crawling before understanding indexing.
Don't neglect GEO from the start
In 2026, learning SEO without GEO amounts to learning half the job. More than half of Google queries trigger an AI Overview, and ChatGPT has more than 900 million weekly users. Yet only 11% of domains are cited by both ChatGPT and AI Overviews. The opportunity is immense for anyone training properly now.
The FAQPage schema, for example, is a strong signal for appearing in AI Overviews, and the optimal citable passage falls between 134 and 167 words. These are concrete skills, free to learn, that make the difference today. To take action on this front, our GEO France Guide brings together the complete method.
Learning on your own works. But guided practice accelerates everything. At some point, observing a real high-performing site says more than ten tutorials.
Our free GEO audit analyzes your visibility in Google and in generative engines, and shows you what to fix first.
