Technical SEO Course

Teaches how to make a website easier for search engines to discover, crawl, render, index, and understand through site infrastructure, performance, and structured data.

If you treat technical SEO as a one-time setup, you will miss the ongoing issues that creep in after CMS updates, migrations, or content changes.

Key points

  • Audit crawlability before writing new content; search engines need to find the page first.
  • Use robots.txt to control crawling, not indexing — the two directives are not interchangeable.
  • Set canonical tags correctly to avoid confusing search engines with duplicate or near-duplicate pages.
  • Check Core Web Vitals monthly because thresholds and your site’s performance can change.
  • Submit XML sitemaps but do not expect instant indexing; they are suggestions, not guarantees.
  • Understand that technical SEO is the foundation, not a quick fix, for organic visibility.

The indexing problem that a course helped solve

A site owner noticed 30% of their pages were not indexed. After taking a technical SEO course, they checked robots.txt and server logs. They found a misconfigured rule blocking key product pages. After fixing it, Google indexed 200 new pages within two weeks. The course also taught them to monitor crawl budget and avoid redirect chains, preventing similar issues in the future.

Three things a technical SEO course teaches you to check first

  • Crawlability Check that search engines can reach your pages. Use robots.txt to allow important URLs and block only irrelevant ones like admin areas.
  • Indexability Ensure pages you want in search results are not blocked by noindex tags or meta robots. Each page should have a clear index status.
  • Site architecture Organise content with a clear hierarchy and internal links. A flat structure helps crawlers discover content and understand page relationships.

Four common mistakes a course will help you avoid

  • Blocking important pages Do not block product pages in robots.txt if you expect them to be indexed. Use noindex on the page itself if you want to exclude it.
  • Incorrect canonical tags Pointing many unique pages to a single unrelated URL dilutes signals. Each canonical tag should point to the true preferred version.
  • Ignoring crawl budget On large sites, wasted crawl budget on duplicate URLs or redirect chains can prevent important pages from being crawled.
  • Broken redirects Avoid redirect chains and broken links. They waste crawl budget, confuse crawlers, and can cause indexing delays or errors that harm organic visibility.

Three areas where course content can become outdated

  • Mobile-first indexing Search engines primarily evaluate the mobile version of pages. Course advice on mobile optimisation from before 2020 may be incomplete.
  • JavaScript rendering How search engines render JavaScript has changed. Courses from a few years ago may give outdated guidance on dynamic content.
  • Core Web Vitals thresholds Google adjusts the thresholds for LCP, INP, and CLS. Course content should be current to reflect the latest performance targets.
