Summary of the features
This free online Checker / Validator not just tells you which of your hyperlinks are dead but it will also show to your where exactly those stale references locate in your HTML code! Such a unique feature makes our checking service stand out from other available problem detection tools, and makes it very convenient for a webmaster to find bad URLs and clean them in no time. It's never been so easy to locate and fix dead weblinks!
This free website validation tool reports only hyperlinks that are really broken - unlike other popular tools which list both good and bad weblinks all mixed together making it very hard to comprehend and work with such "noisy" information. Also our linking problem finder analyses the entire site - its web-content as a whole, keeps track of issues already reported, and doesn't repeat the same invalid URL unless you ask about it: the tool is very flexible.
Dead hyperlinks on websites are not just annoying – their existence may cause some real damage to your online business as well as to your reputation in the Internet!
Because of that a web-site may:
All that presents issue so serious that people sometimes say the "link rot problem" (or linkrot) referring to it: as you may already know "rotten" weblink is just another name for the same "dead URL" situation.
With growth of web-site content it's getting harder and harder to manage relations between individual webpages and keep track of hyperlinks within a site. Unfortunately there are no perfect web-site integrity tools or services that can enforce proper relationship between pages, keep track of moving content, webpage renames etc, and update corresponding URLs automatically. With time this causes some hyperlinks become obsolete, stale, odd, dangling, and simply - dead because they don't lead to valid resources anymore, and visitors are going to get 404 error codes (infamous Page Not Found messages) or other unsuccessful HTTP responses each time when they try to access the web-pages. Modern content management systems (CMS like Joomla!) and blog software may aggravate the problem even more - by replicating the same dead weblinks across numerous webpages which they generate dynamically, so people can be getting 404 errors much more frequently. All the just described happens to internal links all the time.
Why you need our online link checker
Due to lack of adequate problem detection tools (aka URL validators, web spiders, HTML crawlers, website's health analyzers etc) it's really very hard to identify what exact local and external (outbound) hyperlinks became dead, and it's even harder to fix those because for cleaning you need to know precise location of the broken linking tag in the HTML code: without that you will need to scan through thousands source lines to find exact HREF (or other subtag) that causes the problem.
This is exactly where our on-line URL Checker truly shines: it will check your entire site - crawl all pages searching for issues and will detect invalid webpage references on your website telling you precisely where to fix those! For each bad hyperlink found (both internal and outgoing) you will see a screen that contains page source and highlights the actual HTML tag containing the non-working url, so you can correct the rot right away and eventually repair your blog very quickly. That way your visitors won't be annoyed with Page Not Found errors anymore!
As 100% online tool running in the Internet our free Website Scanner & Problem Detector can be used on any computer no mater if it's iMac, PC, MacBook, notebook / laptop, iPad (or even iPhone), Droid or some other mobile device, and whether it runs Windows, Mac / Apple OSX, iOS, Android, Chrome OS / Chromium, WebOS, Linux or UNIX. It's been made Microsoft Windows 8 / 8.1 compatible as well! All popular browsers are fully supported including (but not limited to) IE, Firefox & Mozilla, Chrome, Opera and Safari. All this makes this analyzer a true cross-platform SEO tool always ready for your use! Moreover, our HTTP server spider is capable of crawling and checking any website no matter if it's coded by hand - with pure HTML / XHTML, or is based on PHP, ASP, JSP, Cold Fusion etc or is built using Drupal, Joomla, WordPress, DotNetNuke, Magento, or any other CMS and e-Commerce platforms. Because of that many web-developers and webmasters use our crawler for testing their projects - to quickly detect and address issues if any.
We are getting a lot of positive feedback and many webmasters name this service as one of the best tools available on the World-Wide-Web. Try it yourself to see why it's so popular!
