Everything in One Audit
Every technical check your site needs, automated and prioritized.
Deep Site Crawling
Crawl up to 10,000 pages per audit with customizable depth, speed, and URL exclusion rules. Supports auth-protected pages and sitemap-guided crawls.
Broken Link Detection
Identify all 404s, 410s, 5xx errors, and broken anchor links across your entire site. Find orphaned pages and dead internal links that bleed crawl budget.
Canonical Tag Coverage
Find pages missing canonical tags across every crawl and review each page's canonical target from the Site Health dashboard.
Core Web Vitals (LCP, CLS, INP)
Pull live LCP, Cumulative Layout Shift, and Interaction to Next Paint scores from Google's PageSpeed API for every page. Track trends over time and see which pages fail Google's thresholds.
Uptime Monitoring
HTTP health checks every 10 minutes for every site. Instant downtime alerts via email and Slack. Tracks response time trends and flags when status codes change unexpectedly.
Schema.org Validation
Parse structured data markup across your pages — Article, Product, FAQ, BreadcrumbList, LocalBusiness and more — and flag schemas missing key properties.
Hreflang Tag Analysis
Extract and review hreflang implementations across multilingual sites — see every page's declared language and region alternates in one view.
XML Sitemap Health
Parse XML sitemaps and sitemap index files to guide every crawl, and monitor Google Search Console sitemap status, warnings, and errors in one dashboard.
Robots.txt Compliance
Parse and respect robots.txt rules during every crawl — see which URLs are blocked from crawling and how directives shape what search engines can reach.
Missing Meta Tags
Identify pages with missing title tags, meta descriptions, H1 headings, or duplicate meta data. Get character count analysis and suggestions for optimal tag lengths.
Redirect Chain Detection
Detect redirected pages and multi-hop redirect chains with exact hop counts, so you can point links at the final destination and conserve crawl budget.
NoIndex & NoFollow Audit
Detect accidental noindex tags blocking important pages from Google. Identify nofollow usage patterns, orphaned pages, and pages with no inbound internal links.
One Health Score. Every Issue Prioritized.
SERPHub calculates a 0–100 site health score weighted by issue severity. Errors hurt more than warnings. Warnings hurt more than notices. You always know exactly what to fix first.
- Errors: broken pages, missing titles & meta descriptions, non-HTTPS pages
- Warnings: slow pages, redirect chains, missing canonical tags
- Notices: thin content, long titles, missing Open Graph tags
- Score trends over time — see if you're improving
