As mentioned yesterday, here’s a terrific new tool to investigate potential problems on your website. It’s a rare website which doesn’t have any broken links on it, and Internet Marketing Ninjas’ Find Broken Links, Redirects & Google Sitemap Generator Free Tool is a really well-implemented online application to help you find them. What you’re looking for are any pages or images on your site which are given a “status” of 404 or indeed anything in the 400 series. It does a lot more too.
