Check links in your Plone site using a link monitoring server.

Project description

What is gocept.linkchecker?

gocept.linkchecker is a Plone product which both monitors the availability of links (URLs) within the content of the site and shows which objects are referencing each other.

High level overview
A coloured and grouped list of all links of the site gives a detailed and high level overview on the status of the links.
Author and object level overview
Additional reporting is available to the content authors who can see their personal link status page (My links) as well as an overview over all links in one object (Links tab of object).
Referenced by
A portlet shows whether an object is referenced by another object (due to HTML anchor or img tag).
Replace functionality
Directly edit URLs of (broken) links from the overview without having to locate the link deep in a document.
