SEMrush

SEMrush provides a comprehensive site audit tool that crawls domains to identify technical SEO issues including crawlability errors, broken redirects, and canonicalisation problems. The platform flags hreflang implementation issues, HTTPS configuration errors, and XML sitemap inconsistencies whilst monitoring core web vitals and page speed metrics. Its audit functionality detects duplicate title tags, thin content, and orphaned pages through scheduled crawls, though the interface can feel overwhelming when navigating between site audit, position tracking, and backlink analysis modules.

Ahrefs

Ahrefs Site Audit crawls websites to surface technical SEO problems such as redirect chains, noindex conflicts, and internal linking structure weaknesses. The crawler identifies canonical tag errors, robots.txt blocking issues, and metadata duplication whilst providing insights into page load times and HTTP status code distributions. Its approach to technical auditing emphasises crawl budget optimisation and indexability concerns, though the granularity of certain checks lacks the depth found in specialised crawling tools. The platform flags schema markup errors and alt text deficiencies alongside mixed content warnings, delivering scheduled health scores that track technical debt accumulation over time across monitored domains and subdomains.

Moz

Moz Pro includes site crawl capabilities that detect technical SEO issues ranging from redirect loops to parameter handling problems and XML sitemap errors. The crawler surfaces canonicalisation conflicts, duplicate content instances, and missing meta descriptions whilst tracking page authority distribution across internal link architecture. Its technical audit functionality addresses indexation directives, structured data implementation, and mobile rendering concerns, though the crawl depth and frequency limitations can prove restrictive for larger websites requiring more intensive monitoring. The platform integrates page optimisation recommendations with technical health metrics, combining on-page factors with crawlability assessments to provide holistic site health evaluations.

Screaming Frog

Screaming Frog SEO Spider operates as a desktop crawler that performs deep technical audits by analysing response codes, redirect chains, and canonicalisation implementations across unlimited URLs in the paid version. The tool excels at identifying duplicate content through content hash analysis, broken links, and orphaned pages whilst extracting structured data, hreflang annotations, and pagination implementations. Its raw data approach surfaces XML sitemap discrepancies, robots.txt directives, and indexation conflicts with granular filtering capabilities, though the interface requires technical proficiency to interpret findings effectively. The crawler integrates with Google Analytics and Search Console APIs to correlate crawl data with performance metrics whilst offering custom extraction and bulk export functionality.

Google Search Console

Google Search Console delivers native insights into technical SEO issues directly from Google's indexing infrastructure, reporting coverage errors, crawl anomalies, and mobile usability problems. The platform surfaces structured data errors, security issues, and core web vitals performance degradation whilst providing visibility into manual actions and indexing status. Its Coverage report identifies excluded URLs, redirect errors, and server error patterns alongside soft 404 responses and noindex implementations, though the delayed reporting and sampling limitations restrict real-time troubleshooting capabilities. The tool flags enhancement opportunities for breadcrumbs, sitelinks searchbox, and product markup whilst monitoring HTTPS implementation and intrusive interstitial penalties.
