Broken links can significantly harm your website's search engine optimization (SEO) efforts. Search engines like Google view broken links as indicators of poor website maintenance and low-quality content. When search engine crawlers encounter multiple 404 errors, they may reduce their crawl frequency, potentially causing newer pages to be indexed more slowly. Additionally, broken links create a poor user experience, leading to higher bounce rates and lower engagement metrics, which are important ranking factors.
Regular link checking should be part of your SEO maintenance routine. By identifying and fixing broken links promptly, you can maintain link equity, improve user experience, prevent lost traffic, and ensure search engines can properly crawl and index your entire website.
