Technical SEO makes sure search engines can find, understand and index your pages. If this foundation is weak, even excellent content struggles to rank.
Begin with the checks below, in this order.
Crawling and indexing
Crawl the site with an SEO crawler, review Google Search Console coverage and check robots.txt, canonical tags and the XML sitemap. Fix errors, broken links and unintended noindex tags first.
Site structure and speed
Review internal linking, URL structure, redirect chains and mobile usability, then measure Core Web Vitals to find the pages that load slowly.
Structured data and prioritisation
Validate structured data, then rank the issues you find by impact and effort. Fix the problems that block indexing before you polish smaller details.
