Page Indexing Issue (webmaster tools)

How can i validate and fix the issue?



will it impact my ranking? All the failed validation are of no use to me, any plugin to make the bulk actions on them??

Impact. Review and fix the broken links causing 404 errors, correct unnecessary redirects, and resolve server errors. Check for any content or technical issues preventing pages from being indexed, such as 'noindex' tags or canonical tag issues. For bulk actions tools like Screaming Frog or plugins like Yoast SEO.
