Bulk URL Checker — HTTP Status & Redirect Checker

Why Check URL Status Codes in Bulk

HTTP status codes tell you whether a URL is working (200), redirecting (301/302), broken (404), or experiencing server errors (500). Checking these one at a time is impractical when you have dozens or hundreds of URLs to verify — during a site migration, after a redesign, or as part of a regular SEO audit.

A bulk URL checker automates this process. Paste your URL list, click check, and get results in seconds. You'll immediately see which URLs return errors, which have redirect chains, and which are responding slowly — all the signals that affect your search rankings and user experience.

Understanding HTTP Status Codes

2xx — Success

200 OK is the standard response for a successful request. The server found the resource and returned it. 204 No Content means success but with no response body. These are the codes you want to see for your pages.

3xx — Redirection

301 Moved Permanently tells browsers and search engines that a page has permanently moved to a new URL. Search engines transfer ranking signals to the new URL. 302 Found indicates a temporary redirect — search engines keep the original URL indexed. 307 Temporary Redirect and 308 Permanent Redirect are stricter versions that preserve the HTTP method (GET/POST) during the redirect.

4xx — Client Errors

404 Not Found means the page doesn't exist. 403 Forbidden means the server understood the request but refuses to authorize it. 410 Gone explicitly tells search engines the page was intentionally removed and won't return — a stronger signal than 404.

5xx — Server Errors

500 Internal Server Error indicates the server encountered an unexpected condition. 502 Bad Gateway means an upstream server returned an invalid response. 503 Service Unavailable means the server is temporarily overloaded or down for maintenance. These require investigation and typically indicate infrastructure problems.

Redirect Types and SEO Impact

Redirects are essential for maintaining SEO equity during URL changes. However, each redirect adds latency (typically 50-200ms per hop) and can dilute the link equity passed to the final URL.

Google's John Mueller has confirmed that 301 redirects pass full PageRank, but chains of multiple redirects may lose some signal. The recommended best practice is to redirect directly from the old URL to the final destination — avoid chains through intermediate URLs.

Common redirect mistakes include using 302 (temporary) when 301 (permanent) is appropriate, creating redirect loops (A→B→A), and maintaining chains through deprecated intermediate URLs. This tool detects all of these patterns.

Common SEO Issues This Tool Detects

• Long redirect chains — More than 2 hops slow down page loading and dilute link equity.
• Mixed HTTP/HTTPS — Redirecting from HTTPS to HTTP within a chain creates security warnings and mixed content issues.
• 302 instead of 301 — Temporary redirects don't pass full SEO equity. If the move is permanent, use 301.
• Slow responses — Pages taking more than 3 seconds indicate server performance issues that affect Core Web Vitals.
• Soft 404s — Pages returning 200 but with content indicating the page doesn't exist. Check these manually.
• Server errors (5xx) — Persistent 500 errors cause pages to be dropped from Google's index.

Use Cases

Website Migration

When moving to a new domain or restructuring URLs, use Compare mode to verify that every old URL redirects to the correct new URL via 301. This preserves your search rankings during the transition.

SEO Audits

Export your sitemap URLs or crawl data and check them in bulk. Identify broken links, redirect chains, and server errors that may be hurting your search performance.

Competitor Analysis

Check competitor URLs to understand their redirect patterns, identify broken pages in their backlink profile, and find opportunities.

Link Building

Verify that your backlinks are still live and pointing to the correct pages. Identify any that now return 404 or redirect to unexpected destinations.
