LinkController is a group of programs designed to take away much of the work of maintaining the links in a web site. Instead of the user running the program checking whether links are broken, LinkController does this automatically. When it finds a broken link it checks it several times across several days before reporting it broken. This means that if a link is repaired in the meantime (a common case), the user will never be bothered.

WebTester is a handy site management tool, the primary purpose of which is to check your site for broken links. It will report both on missing files and on those which exist but aren't referenced. It can also check the validity of your external links. (That way, if someone moves or removes a page to which you've linked, you'll know that the link needs to be updated!) The script is fairly robust; in addition to following "straight" links, it will also parse and follow links in image maps, in text embedded via SSIs, and (optionally) in CGI-generated pages. It will let you know the effective "download" file size of your pages, and will provide estimates of how long they'll take to download at various connection speeds. Finally, it can create for you a simple "site map" showing, in outline format, all of your site's pages. (The site map can be included via SSIs on other pages.)

This script allows you to check the validity of all HTML links on a Web site. Most can start at one or more "seed" HTML files, and recursively test all URLs found at that site. This program doesn't follow URLs at other sites, but it does check their existence. Major features include: Local URLs are read from the filesystem when possible, Basic server-side includes (aka SSI or SHTML) are checked, Latest standards are supported-- HTML 4.0, HTTP 1.1, latest URI-parsing scheme, and Links are traversed breadth-first.

LinkScan is the industrial strength link checking and website management tool. It also does HTML validation and creates two types of publication quality SiteMaps. LinkScan is offered in two versions: LinkScan Workstation is a single-user implementation designed for individual content developers in large enterprises, and for organizations having smaller websites with up to 300 documents, and LinkScan Server is the complete multi-user, enterprise LinkScan implementation including LinkScan/Dispatch and handles extremely large websites comprising up to or more than 250,000 HTML documents and/or 100,000 external links.

This program allows you to set up a link exchange page with the minimum of effort, as you trade links with other sites. It can be configured to accept all links or to only accept pages that contain a reciprocal link. The list can be displayed randomly or in order of sign-up. You can run a return link check at any time which flags and removes all non corresponding sites. The web based admin area lets you remove and update links.
