On-Page SEO Checker & Technical Audit Tool
Audit a webpage for technical SEO issues and check keyword targeting across meta tags, headings, copy, images, social metadata, and structured data.
On-Page SEO & Indexability Checker
Analyse on-page SEO factors including titles, headings, copy, links, structured data, and hreflang tags to pinpoint issues and improve search visibility.
HTTP Status Response Verification
Checks the final HTTP status code to verify whether the page loads successfully (200 OK) or fails due to client/server errors (4xx/5xx).
Robots.txt Crawl Permission Check
Audits your robots.txt file to confirm if search engine crawlers are explicitly allowed or disallowed from accessing the final URL.
Meta & X-Robots Directives Analysis
Checks directives across both HTML meta tags and HTTP X-Robots-Tag headers to detect blocking rules like noindex or none.
Canonical URL Alignment Audit
Determines whether the page is self-referencing, missing a canonical tag, or canonicalised away to a different target URL.
Protocol (HTTP/HTTPS) Checker
Check your website's protocol configuration to ensure HTTP redirects to HTTPS, uses permanent redirects, and resolves to the correct final URL.
HTTP to HTTPS Redirect Verification
Checks whether unencrypted HTTP traffic automatically redirects to HTTPS to ensure user security and consolidate link equity.
Redirect Chain & Hop Detection
Monitors total redirect hops and flags setups with excess redirects to help reduce crawl latency and preserve crawl budget.
Final HTTPS Status Code Monitoring
Ensures the final HTTPS destination serves a valid 2xx status code rather than resolving to error pages (4xx/5xx) or unresolved redirect loops.
Canonical Endpoint Consistency Check
Verifies that both HTTP and HTTPS requests ultimately resolve to the exact same final URL to prevent split signals and duplicate content issues.
SEO-Friendly URL Checker
Check whether a page's URL follows SEO best practices by analysing its structure, length, target keyword, hyphens, query parameters, and readability.
