To view the broken links to your Web Pages and the source URL for them:
Log into Google Webmaster Tools and access your site (you have to be verified as a site owner). Click Web Crawl from the Diagnostics tab. Click Not Found to view the URLs that return 404 errors. :five:

1.Broken Link Checker for WordPress
First up is Broken Link Checker. This plugin monitors links in your pages, posts, comments, and even custom fields.
2.Xenu?s Link Sleuth (Windows Only)
Xenu?s Link Sleuth is a free Windows app that scans entire websites for broken links. Just provide a URL and it will take care of the rest.
3.Screaming Frog SEO Spider (Windows & Mac)
Screaming Frog is similar to XLS. It?s a standalone desktop app for Windows, Mac, and Ubuntu. Give it a URL and it?ll scan the entire site.
Unlike Xenu?s Link Sleuth, Screaming Frog is explicitly intended for site optimization. It dives deeper into page-level elements like heading tags and meta data.
Screaming Frog?s free version limits the number of pages that can be crawled. The licensed version removes that limit, unlocks all configuration options, allows saving/uploading of crawls, adds source code search, and includes customer support. :breakpc1:
