Technical SEO removes the friction between your content and the crawler. Start with a full crawl to surface broken links, redirect chains, and orphan pages. Tools like Screaming Frog, Sitebulb, or Ahrefs' Site Audit can crawl most sites within minutes and generate reports that would take days to compile manually. The first crawl of a site you inherit is always revealing — almost every site has more technical debt than its owners realize.
Check indexation coverage in Search Console next, then verify canonical tags and XML sitemaps are telling a consistent story. The Coverage report in Search Console categorizes every URL on your site as indexed, excluded, or errored. Excluded URLs are not always problems — noindexed pages and canonicalized duplicates appear here intentionally — but any unexpected exclusions or coverage drops should be investigated immediately.
Redirect chains are one of the most common and underappreciated technical issues on established sites. Each redirect in a chain costs crawl budget and dilutes link equity slightly. Every redirect should be a single hop from original to final destination. Audit all redirects in your crawl output and flatten any chains longer than one step.
Site architecture affects both user experience and crawl efficiency. Every important page on your site should be reachable within three clicks from the homepage. Pages buried deeper in the architecture receive less crawl attention and tend to accumulate less internal link equity. Flat architectures outperform deep hierarchies for both crawlability and PageRank distribution.
Core Web Vitals are now firmly embedded in Google's ranking algorithm, and their technical underpinnings belong in any technical audit. Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift all have specific technical causes and solutions. Run your key templates — homepage, article pages, category pages — through PageSpeed Insights and prioritise fixes on the templates that appear most frequently in your URL structure.
Log file analysis is an advanced but powerful audit technique. Server logs record every request Googlebot makes to your site, revealing which URLs it prioritises, how often it crawls each section, and where it encounters errors. For large sites with millions of URLs, log analysis often reveals crawl budget problems that crawler-based audits miss entirely.
Prioritise fixes by impact: issues affecting site-wide templates outrank one-off page problems every single time. A broken canonical implementation on your article template affects thousands of pages. A broken link on a single archived post affects one. Build your fix backlog as a prioritised roadmap, group fixes by template and theme, and document every change so you can measure its impact in Search Console after the next crawl cycle.
