Site Audit FAQ

Common questions about Nightwatch's technical SEO site auditor.

An SEO site audit is a comprehensive analysis of your website's technical health, on-page SEO, and performance factors that impact search engine rankings. It identifies issues like broken links, duplicate content, missing meta tags, slow page speed, crawl errors, and mobile usability problems — then prioritizes them by severity so you know what to fix first. Nightwatch's site audit gives you a complete technical health score with actionable fix suggestions.
We recommend running a full site audit at least once a month, or after any major site change (redesign, CMS update, content restructure, large migration). Nightwatch lets you schedule automated audits and tracks issue history over time so you can see whether your technical SEO is improving or regressing.
Nightwatch detects crawl errors, broken internal and external links, redirect chains, missing or duplicate title tags and meta descriptions, missing H1s, canonicalization issues, duplicate content, slow-loading pages, mobile usability problems, orphan pages, and more — across your entire site or specific sections.
Yes. Every issue comes with a clear severity rating (critical, warning, or info) and a specific fix recommendation. Critical issues like broken links or missing titles include step-by-step guidance and links to relevant documentation so your team can resolve them quickly.
Yes. Nightwatch stores your audit history so you can track your site health score over weeks and months. See which issues were fixed, which are new, and whether your overall technical SEO is trending in the right direction — essential for demonstrating progress to stakeholders or clients.
