Key takeaways

  • Technical SEO is the foundation for organic visibility.
  • Covers crawling, indexing, site architecture, structured data, and Core Web Vitals.
  • Not a one-time setup—requires recurring audits.
  • Robots.txt and noindex serve different purposes.
  • Canonical tags help manage duplicate content.

This course covers the essential technical SEO topics you need to know as a beginner.

Example: Fixing a crawl issue on a blog

  • You notice a blog post isn't appearing in Google Search.
  • Check Google Search Console: the page is "Discovered - currently not indexed".
  • Review robots.txt: ensure the page isn't blocked.
  • Check the page's meta robots tag: confirm it's not set to "noindex".
  • Verify the page has internal links from other indexed pages.
  • Submit the URL for indexing via Search Console.
  • After a few days, the page appears in search results.

Quick start: 5 steps to begin your technical SEO course

  1. Set up Google Search Console for your site.
  2. Submit an XML sitemap to help Google discover your pages.
  3. Review your robots.txt file to ensure important pages are not blocked.
  4. Check for duplicate content and implement canonical tags where needed.
  5. Test your Core Web Vitals using PageSpeed Insights or Search Console.

How to judge if you need a technical SEO course

  • You have a website but don't know why pages aren't indexed.
  • You see crawl errors or warnings in Search Console.
  • You want to improve site speed and mobile usability.
  • You're planning to add structured data for rich results.
  • You manage a large site and need to manage crawl budget.

Common mistakes in technical SEO

  • Treating technical SEO as a one-time setup instead of a recurring audit process.
  • Blocking important pages in robots.txt while expecting them to be indexed.
  • Using canonical tags incorrectly, such as pointing many unique pages to a single unrelated URL.
  • Ignoring crawl budget, duplicate URLs, redirect chains, or broken internal links on large sites.
