SEO Audit Checklist PDF

Why it matters

Without a checklist, technical SEO audits become inconsistent, and critical issues such as blocked crawling, duplicate metadata, slow pages, or schema errors can be missed. A standardised checklist ensures every audit covers indexing checks in Google Search Console, robots.txt, XML sitemaps, noindex directives, and canonical tags so search engines can discover and index the correct URLs. It also verifies site architecture checks such as orphan pages, internal linking, breadcrumb structure, and crawl depth, which directly affect crawl budget and indexation efficiency.

Core Web Vitals are now standard audit items, especially LCP, CLS, and INP. Mobile usability checks cover viewport setup, tap targets, readable text, and intrusive interstitials or pop-ups. Technical audits usually include title tags, meta descriptions, and other head elements to catch duplicates, missing tags, or over-optimisation. Structured data validation is commonly included, with checks for schema types such as articles, products, FAQs, and breadcrumbs. HTTPS and security checks matter, including SSL coverage, HTTP-to-HTTPS redirects, and mixed-content issues. A checklist should also test broken links, redirects, response codes, and server or render problems that can affect crawlability.

Where it changes your decision

• When planning a site migration: the checklist ensures you verify redirects, canonical tags, and indexation before and after the move, preventing traffic loss.
• When diagnosing a sudden traffic drop: running the checklist helps isolate crawl errors, server issues, or Core Web Vitals regressions that may have caused the decline.
• When onboarding a new client or taking over an existing site: the checklist provides a repeatable baseline to document current issues and track improvements over time.
