Comprobador 404 y escáner de enlaces rotos

Broken links cause real damage to your site's SEO and user experience. They waste crawl budget, frustrate visitors, and can even prevent your important content from being discovered. You need to identify these issues fast, before Googlebot hits them again. A 404 checker is your first line of defense against these problems. It scans your pages to find links that lead nowhere. You'll use it to check a single, critical page after a migration, or to scan a bulk list of URLs to catch site-wide issues. Every time Googlebot encounters a 404, it's wasted time and resources that could have been spent crawling valuable pages. What Is a Broken Link Checker? A Broken Link Checker is a free browser-based tool that scans a specific URL or a list of URLs to identify any outbound or internal links that return a 404 Not Found error. It acts as your personal 404 checker, simulating how a search engine or a real user would encounter links on your page. You give it a starting point, and it tells you exactly where the broken connections are. There's no login needed to use the Broken Link Checker. Why It Matters for SEO Broken links impact your SEO in several direct ways. First, they waste crawl budget. Googlebot only gets a finite crawl budget for your site; for larger sites, this might be hundreds of thousands of URLs, for smaller ones, it could be just a few thousand per day. Every time Googlebot hits a 404, it's a wasted request. This means fewer legitimate, indexable pages get crawled, and new content might take longer to appear in search results. Second, broken links severely damage user experience. Imagine clicking a menu item or an internal link within an article only to land on a "Page Not Found"…
