Technical SEO issues, such as broken links, slow page load times, and mobile-friendliness, can significantly impact bounce rate. Regularly auditing your site for technical issues and addressing them promptly can improve user experience and reduce bounce rate. Use tools like Google Search Console, PageSpeed Insights, and mobile-friendly testing to identify and fix issues. Ensuring your site is technically sound not only helps with SEO but also enhances user satisfaction, leading to lower bounce rates and better overall site performance.
