Technical SEO audit using only Google search operators

Executive overview

Most websites have technical SEO problems that go unnoticed. Google's site search operators expose them without any paid tools.

Run a handful of targeted queries against your domain to surface indexation errors, redirect failures, and unwanted pages. Fix these before investing in links or content.

Google search operators alone can diagnose the most damaging technical SEO issues on any website.

Redirect and indexation checks

• Test all four domain variants: HTTP/HTTPS × www/non-www — only one should load without redirecting
• site:domain.com -inurl:https — finds unsecure pages still indexed by Google
• site:domain.com inurl:www — checks for www versions indexed alongside the canonical
• Any page loading without a redirect from the non-canonical version is a duplicate content risk

Spotting hacked or broken pages

• Unexpected outbound links (e.g. gambling or unrelated sites) on indexed pages signal a hack
• Fix hacked pages before any other technical work — they invalidate all other audit results

Title tag and branding issues

• site:domain.com intitle:wrongbrand.com — finds pages where title tags reference the wrong domain
• Mismatched titles and domains reduce click-through rates
• E-commerce sites with old .com titles on a .co.uk domain are a common example

Unwanted indexed pages

• site:domain.com inurl:page or inurl:sort — surfaces paginated and parameter URLs that should be noindexed
• WordPress-specific: search for inurl:tag, inurl:author, inurl:hello-world, or inurl:welcome-to-wordpress
• site:domain.com lorem ipsum — finds pages still using placeholder dummy text
• site:domain.com filetype:pdf — reveals sensitive documents (salaries, addresses) accidentally indexed

Limits of Google-only audits and when to use a tool

• Google recrawls low-priority pages infrequently — results can be stale or incomplete
• A dedicated crawler (e.g. Ahrefs Site Audit) runs on demand and checks 100+ issue types automatically
• Automated crawls catch 301 chains and 404s without manual URL-by-URL checking
• Scheduled weekly crawls let you monitor technical health continuously
• Custom queries in a crawl tool let you filter by status code, title content, or URL pattern and export for bulk fixing
