subject: Webmasters: Customize those error pages! [print this page] Let me ask you this questionLet me ask you this question. How many times have you made changes to the page structure of your site? Ten times? 100 times? 1000 times? If you have a large site, the number of changes can grow rapidly. This is especially true if you deal with dynamic sites that are driven by a complex scripting language and a database.
Now let me ask you one more question. How many times have you "fat fingered" the keyboard when typing code? I cannot speak for anyone else, but I do it all the time. Now, what happens when you are coding hundreds or thousands of lines of code? Are you going to catch that one little mistake, or are your clients going to catch it?
So, what happens when a link is no longer active on your site, or when you "fat finger" while typing your code and a link cannot be found? Error pages are generated. The most common of these is the 404 error. This error is generated by your web server software to let the end user know that it cannot find the file specified. The big issue here is that this page does not include a link back to your site. And unless you are the server administrator, it may not include your email address, in which case the end user cannot notify you of the dead link.
There is a new trend among hosting providers to capitalize on your dead links. That's right. They are making money from pages that don't exist on your site! You might think this concept is silly, but I assure you, there is big money in error pages. Just think about how many times a day end-users might "fat finger" typing in URLs. Let's just say it happens 1,000 times per day (and I'm probably being conservative here). Now multiply that by an average of $0.10 per click for the credit the host receives when the end-user starts browsing their "convenience page". If you are quick at math, you figured out that that equals $100 per day! Now, if you take into consideration the size of the Internet and start scaling this figure accordingly, you can easily see where this is a seven-figure industry.
What can you do about this? How can you stop your web host from profiting from your visitors without your permission? How can you start getting a piece of this very lucrative pie? The answer is really quite simple.
Most web hosting providers will allow you to customize at least a minimal subset of the configuration parameters of the web server for your hosting account. I'm going to show you exactly how to do this for Apache, the most common web server application on the Internet. Similar steps can be taken for IIS or any other web server application, but I trust that you can use Google to find those specific commands.
