Let our map of the Web, state-of-the-art robots, and network of powerful computers protect the integrity of your Web site. We'll send you weekly status reports plus immediate error notices when something breaks.

Know your site is working

Your links can break at any time. If you link to another site, they can break your links by deleting or moving pages without your knowledge.

Save Time

We not only report the errors, we tell you exactly where they are and which pages are affected. You can focus on your important and creative tasks and leave the grunt work to our robots.

Keep Traffic Flowing

When you reorganize or update your site, you often have to move, rename or delete pages. Without us you won't know whether you've broken links from other sites to yours.

The premier link verification service available anywhere.

• Daily checking catches errors before customers do — We report all new problems by email within 24 hours
• Checks every link within your site every day — No more broken links from typos and editor bugs
• Checks every link to other domains every day — Know when they delete a page and leave your link dangling
• Checks links INTO your site every day with our huge map of the Web — Know when you break someone's link by deleting a page
• Weekly status reports of problems and what you've fixed
• A full list of links to your site is available, upon request

Our map of the Web:

• Monitors links both FROM and TO your site
• Contains over five billion links from over 30 million sites
• We scan millions of pages a day to keep the map current

Our Robot (LinkWalker):

• Automatically checks customer sites nightly
• Obeys all robot protocols
• Fully supports frames and client-side image maps
• Checks all static and active HTML pages
• Ignores all FTP, Gopher, News and mailto: links
• Scans over 1,000 sites in parallel to minimize the load on each site (this puts less demand on your server than one person does with a browser)
• Tracks IP addresses to avoid simultaneous scans of multiple sites on the same server
• Makes no parallel (asynchronous) requests to any site
• Fetches no more than one file every 15 seconds
• Remembers and doesn't fetch unchanged files
• Skips the content of graphics and animation files to reduce server load

Robot protocols:

• LinkWalker obeys voluntary robot guidelines, including the robots.txt standard for exclusion of files
• LinkWalker identifies itself in the user-agent field so you can see its visits in your log
