Technical SEO FAQs
What is technical SEO?
Technical SEO is everything about how search engines (and AI crawlers) discover, crawl, render, and index your site - separate from content quality. It includes Core Web Vitals, mobile-friendliness, crawl budget, robots.txt, XML sitemaps, canonical tags, structured data, JavaScript rendering, and internationalisation markup.
My rankings dropped. Is it technical?
It can be. Check indexing directives, robots rules, canonicals, redirects, rendering, migrations, server errors and Core Web Vitals alongside content changes, links, competitors and confirmed search updates. A proper audit separates correlation from the actual cause.
What Core Web Vitals targets matter?
Google's current good thresholds at the 75th percentile are LCP within 2.5 seconds, INP within 200 milliseconds and CLS at or below 0.1. Faster can improve user experience, but a specific speed improvement does not translate into a guaranteed number of ranking positions.
How does technical SEO support AI search?
AI-search systems still need accessible, well structured source pages. Clean HTML, stable URLs, sensible crawler controls, accurate author and organization data, and schema that matches visible content reduce ambiguity. No schema type guarantees an AI citation.
