If you have searched for ways to learn SEO on your own, you have probably come across popular free video courses published around 2018. Many of these tutorials are still circulating on YouTube and learning platforms, attracting new viewers every day. They promise step-by-step guidance on how to do SEO yourself without paying for expensive training. But search has changed dramatically since then. Mobile-first indexing, core web vitals, helpful content systems, and AI-powered search have all reshaped the landscape. This article explores which lessons from 2018-era courses still apply and how to update your DIY SEO approach for today.

Why 2018 SEO Video Courses Became So Popular
The 2018 era produced a wave of accessible SEO education. Creators broke down complicated topics into simple video lessons covering keyword research, on-page optimization, and link building. These courses were free, easy to follow, and often accompanied by practical demonstrations using tools like Google Search Console and keyword planners. For many small business owners and bloggers, they were the first introduction to SEO, and their simplicity remains appealing.
Lessons That Still Hold Up Today
Many fundamentals taught in 2018 remain valid. Search engines still need to crawl and index your pages, so technical basics like sitemaps, clean URLs, and proper internal linking still matter. Keyword research remains essential for understanding audience demand. Writing descriptive title tags and meta descriptions still influences click-through rates. Earning high-quality backlinks from relevant websites continues to build authority. If a course focused on these timeless principles, it still offers value.
What Has Changed Since 2018
Several major developments mean older courses are incomplete or occasionally misleading. Pay attention to these shifts when watching legacy content:
- Mobile-first indexing: Google now primarily uses the mobile version of your site for ranking.
- Page experience and Core Web Vitals: loading speed, interactivity, and visual stability are measured more precisely.
- Helpful content focus: search systems reward people-first content and demote pages created mainly for rankings.
- E-E-A-T: experience, expertise, authoritativeness, and trust have become central to quality evaluation.
- AI search: generative answers now appear in results, changing how users interact with search.
Outdated Tactics to Avoid
Some 2018 tutorials recommended tactics that are now ineffective or risky. Exact-match keyword density targets, mass directory submissions, and aggressive anchor text optimization no longer deliver results and can trigger spam filters. Short, thin blog posts written solely to target a keyword rarely rank today. Be skeptical of any lesson that emphasizes tricks rather than genuine value for users.
A Modern DIY SEO Process
To do SEO yourself today, start with a technical health check using Google Search Console and a free site crawler. Fix indexing issues, broken links, and mobile usability problems. Next, conduct keyword research focused on search intent, grouping related terms into topic clusters. Create comprehensive, original content that answers questions better than competing pages, adding personal experience and examples wherever possible.
Optimize each page with a clear title, descriptive headings, and helpful internal links. Improve page speed by compressing images and minimizing heavy scripts. Build authority by creating shareable resources and reaching out to relevant websites for genuine mentions. Finally, measure results monthly and refine your strategy based on real performance data.
Supplementing Old Courses With Current Resources
Older video courses can still serve as a friendly introduction, but pair them with up-to-date sources. Google Search Central documentation, recent industry blogs, and newer free courses from reputable SEO tool providers cover current best practices. Follow trusted practitioners who regularly discuss algorithm updates. This combination gives you a solid foundation without relying on outdated assumptions.
Tools to Use Alongside Any Course
Whichever course you follow, practical tools turn lessons into action. Google Search Console is essential, showing which queries bring impressions, which pages are indexed, and what technical problems exist. Google Analytics helps you understand how visitors behave after they arrive. PageSpeed Insights measures performance and Core Web Vitals, highlighting specific improvements to make.
For keyword research, free versions of popular SEO platforms, Google autocomplete, and the "People Also Ask" box offer plenty of ideas for beginners. A free website crawler can uncover broken links, missing titles, and duplicate content. Many content management systems also offer SEO plugins that guide you through on-page optimization. Learning to use these tools confidently is arguably more valuable than any individual video lesson, because they show you exactly what is happening on your own website rather than on a hypothetical example.
Final Thoughts
Free 2018 SEO video courses can teach you the basics, but they should not be your only guide. Focus on the timeless fundamentals, avoid outdated tricks, and supplement your learning with current resources that reflect mobile-first indexing, helpful content, and AI search. With persistence and the right information, doing SEO yourself is entirely achievable, and when you are ready to scale, integrating SEO into a broader digital marketing plan will multiply your results.
