Paste multiple URLs to validate their structure, classify HTTP status patterns, detect broken links and 404 errors, and analyze redirect indicators — instantly, no login required.
The request was successful. The page exists and loaded correctly.
Permanent redirect. The page has moved to a new URL. SEO value transfers.
Temporary redirect. The page is temporarily at a different URL.
Access denied. The server understood the request but refuses to fulfill it.
The page does not exist. Most common broken link error in SEO audits.
Internal server error. The server failed to process the request.
Service unavailable. The server is temporarily down or overloaded.
Malformed URL that cannot resolve. Missing protocol, invalid TLD, or typo.
Find broken internal links, dead backlinks, and pages that return 404 errors. Fix them with 301 redirects to preserve SEO value.
Verify that every URL in your XML sitemap is valid and accessible before submitting to Google Search Console.
Validate external links in your content before publishing. Avoid linking to dead pages or domains that no longer exist.
After moving a site to a new domain or restructuring URLs, verify that all redirects are in place and no pages return 404.
Scan lists of URLs collected from crawlers or analytics tools to quickly identify which ones need attention.
Validate URL lists from spreadsheets or CMS exports before using them in reports, redirects, or link-building campaigns.
Browser security prevents direct HTTP requests to external domains due to CORS policies. Live status checking requires a server-side proxy. This tool performs instant client-side URL structure analysis — identifying malformed URLs, likely 404 patterns, redirect indicators, and validity issues without any server calls. Results are immediate and your URL list stays private.
A bulk 404 checker scans multiple URLs to identify which ones are likely returning a 404 Not Found error. In SEO, 404 errors on pages that previously had backlinks or internal links waste link equity and create poor user experiences. This tool flags URLs with 404-indicative patterns so you can prioritize which pages need redirects or restoration.
A 301 redirect is permanent — search engines transfer the full SEO value of the original URL to the destination. A 302 redirect is temporary — search engines keep indexing the original URL. Always use 301 redirects when permanently moving or consolidating pages to preserve rankings.
For internal broken links: either restore the missing page, update the link to point to an existing page, or set up a 301 redirect from the broken URL to the correct destination. For external broken links: replace them with a working alternative URL or remove the link entirely.
This tool processes up to 100 URLs per run. For larger lists, split your URLs into batches of 100 and run multiple checks. For full-site crawls with thousands of URLs, consider dedicated crawling tools like Screaming Frog or Ahrefs Site Audit.
