Find and fix link problems the easy way!

This free on-line Checker 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! This unique feature makes our checking service stand out among other available problem detection tools - by making it so easy for webmasters to find bad URLs and clean them up in no time.
It's never been so easy to locate and fix dead weblinks!

This free website validation tool reports only things that are really broken - unlike other popular solutions that list both good and bad hyperlinks 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 specifically: the URL Checker tool is very flexible!

Why having broken weblinks is so bad?

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 those, a web-site may:

  • Lose some of the existing customer base (current users sooner or later will get frustrated enough with Page Not Found errors to never come back)
  • Get problems with getting new customers (because of the dead weblinks people simply won't be finding things/pages they are looking for).
  • Damage your reputation online (most visitors consider errors like that to be a sign of laziness, carelessness, and disrespect to them)
  • Negatively impact on your website ranking with major search engines like Google, Yahoo, Bing, etc.

All that presents an issue so serious that people sometimes say "link rot" referring to it: as you may already know, "rotten" weblink is just another name for the same "dead URL" thing.

What is the nature of invalid hyperlinks?

With the growth of web-site content, it's getting harder and harder to manage relations between individual webpages and keep track of weblinks within the site. Unfortunately, there are no perfect web-site integrity tools or services that can check and enforce a proper relationship between pages, keep track of moved content / renamed webpages, and update each corresponding URL automatically. With time this causes some of your internal links to become obsolete, stale, odd, dangling, and simply - dead because they don't lead to valid resources anymore. Modern content management systems (CMS like Joomla) and blog software may aggravate the problem even more - by replicating the same broken links across numerous webpages which they generate dynamically, so people will be getting 404 errors much more frequently. Your visitors are going to get 404 error codes and see 'Page Not Found' messages (or other unsuccessful HTTP responses) each time when they try to access those resources.
With outbound references, the situation is even worse: the website you are linking to can change names and locations of their pages any time without any notice breaking previously working backlinks. The external servers can be brought down (temporarily or forever) or their domains expire or be sold. Alas, you don't have any control over such things, so the only good remedy would be performing regular sanity tests probing each single outgoing reference to make sure it's still alive and NOT pointing at some non-existing content.

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 Spider tool truly shines: it will crawl your entire site - check 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 customers won't be annoyed with 'Page Not Found' errors anymore when clicking your weblinks.

As 100% online tool running in the Internet, our free Website Scanner & Problem Detector can be used on any computer no matter if it's Mac, PC, notebook / laptop, iPad (or even iPhone), Android or some other mobile device, and whether it runs Microsoft Windows, MacOS, Apple iOS, Android, Chrome OS, Linux or good old UNIX. Our deep Dead Link Checker can be used with all popular browsers, including (but not limited to) Chrome, Firefox, Safari, MS Edge, Opera, and Internet Explorer (IE). All this makes this analyzer a true cross-platform SEO tool always ready for your use! Because of that, thousands of web-developers, QA specialists, and webmasters use our validator for testing their internet projects - to quickly detect broken links and address those. 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 or is built using Drupal, Joomla!, WordPress, DotNetNuke, Magento, Blogger, TYPO3, or any other CMS and e-Commerce platforms.

We are getting a lot of positive feedback and many webmasters name this service as one of the best solutions available on the World-Wide-Web. Try it yourself to see why it's so popular!

More cool & free features are coming soon including higher limits, MS Excel export, and for SEO experts - more configurable parameters.
