Technical SEO
Site speed, mobile, sitemaps, robots.txt and Core Web Vitals.
Technical SEO covers the infrastructure a search engine or AI crawler depends on before it ever reads your content: how fast the page loads, whether it works on mobile, whether your sitemap and robots.txt actually say what you think they say. These issues are invisible to a normal visitor but can silently cap a page\u2019s ranking or keep it out of the index entirely.
Lesson 1
Site Speed and Core Web Vitals
Core Web Vitals are a set of measurements Google uses to judge how good a page feels to use.
Lesson 2
Mobile-Friendliness and Crawlability
Google primarily uses the mobile version of a page to decide how it should rank, an approach called mobile-first indexing.
Lesson 3
Sitemaps, Robots.txt and Canonical Tags
An XML sitemap is a file that lists the important pages on a site, helping search engines find and prioritize them, especially useful for large sites or pages with few internal links pointing to them.
Lesson 4
Content Cannibalization and the Year-in-URL Trap
Content cannibalization happens when two or more pages on the same site target the same topic and compete with each other for the same search rankings, instead of one strong page winning clearly.
