Broken page & mixed content detection

We crawl and index your entire website, just like Google. As soon as we detect a broken link on your site, we'll notify you. This includes error pages like 'page not found', 'internal server error' and even 'mixed content' (when HTTP elements are included on an HTTPS website).

found broken links
01

We check for broken links constantly

No need to wait for customers telling you it's broken.

Would you know if the marketing team changed some URLs in the CMS but accidentally broke something? Or if your developer hastily shipped an update to your site, but forgot to check key pages?

Our crawler does daily checks of your website and keeps you informed of any broken pages.

How links might get broken

  • Someone at marketing accidentally changed some urls in the CMS
  • Dev team hastily shipped an update on friday afternoon but forget to check key pages
  • URL’s to external pages change over time
mixed content
02

Avoid mixed content, avoid security risks

We detect unsecure resources on a secure page

Mixed content warnings happen when you include HTTP elements on an HTTPS page. In other words: when you include unsecure resources on a secure (via an HTTPS SSL certificate) page.

Oh Dear finds and reports these problems. This allows you to fix the problem (ie: load the resources over HTTPS instead of HTTP) and help keep both your website and your users safe.

If you don't fix mixed content alerts, you risk getting your Javascript or CSS blocked by the browser, which might just break your entire website.

Let’s get technical (if you’re into that)

You don’t need to be computer savvy to set up our tool. But if you are, we’re happy to explain exactly how it works and how you can customize Oh Dear to your specific needs.

stopwatch

Reporting broken links

how we crawl your site pages

Oh Dear will crawl your site and all its pages and create a summary for you with all pages that meet these criteria:

  • The HTTP status code is not a HTTP/2xx or HTTP/3xx
  • The page took longer than 5 seconds to load

We treat all pages in the HTTP/200 to HTTP/399 range to be OK, as long as they load in less than 5 seconds. Anything that deviates from that pattern will be reported.

exclude urls

Exclude certain URLs

ignore particular URL patterns

Some URLs will trigger a 404 on purpose or might be more difficult to fix in the short-term. To help your notifications, you can ignore particular URL patterns per website in your settings screen per site.

You can add URLs using a simple pattern. This example will ignore any crawl errors on the URLs that start with /private/, /forum/admin/ or that have /edit anywhere in the URL.

We also exclude several particular URLs globally, to avoid making these reports too noisy.
