Technical SEO is the work that removes blockers. No amount of content earns rankings if pages cannot be crawled, are not indexed, load too slowly on mobile, or send contradictory canonical signals.
The audit order that finds the most in the least time: crawlability (robots.txt, redirect chains, orphan pages), indexation (canonicals, noindex, duplicate templates), speed and Core Web Vitals, then structured data. Fix in that order — an unindexed page cannot be optimised.
Most sites have far fewer technical problems than they fear, but the ones they do have are systemic: a single bad canonical rule or a filter generating thousands of URLs can suppress an entire section. That is why a crawl beats guesswork.

Not a 200-item audit — the handful of crawl, index and speed issues that actually change positions, in priority order.
hreflang is the most commonly broken tag in international SEO. The rules that matter, and the mistakes that send the wrong language to the wrong market.
Internal links are the one ranking factor you fully control — no outreach, no budget. How to spread authority and lift pages close to ranking.
Frequently asked questions
What should I fix first in a technical audit?
Anything that blocks crawling or indexing — robots.txt rules, noindex tags left over from staging, redirect chains, broken canonicals. Speed and schema matter, but only after Google can actually reach and index the page.
Do Core Web Vitals really affect rankings?
They are a real but modest signal, and they matter most as a tiebreaker between comparable pages. Their bigger effect is on conversion: slow pages lose visitors regardless of ranking.
How often should I run a site audit?
Monthly for an active site, and always after a redesign, migration or CMS change. Most serious technical problems arrive with a deploy, not gradually.
