Technical SEO Audit

How Crawl Errors Block Organic Rankings

Googlebot allocates a crawl budget to every site based on its authority and server response speed. When crawl budget is consumed by redirect chains, soft 404 responses, duplicate URLs, or blocked JavaScript resources, Googlebot never reaches your highest-priority pages. Canonical tag errors create a separate class of problem: conflicting canonical signals cause Google to index the wrong page variant, attributing ranking signals to non-canonical URLs.

What the Technical Audit Covers

• Crawlability: Full site crawl with redirect chain mapping, robots.txt and sitemap validation, Googlebot log file analysis, crawl depth and internal link architecture.
