#35-Monitoring Web Page Changes: http://www.WatchThatPage.com

February 04, 2004

LTA Overview

Despite the best of intentions, busy professionals may not have the time or discipline to systematically monitor relevant professional, political, media or scientific websites for new information. Perhaps readers of this LTA have already defaulted on one or more of their New Year’s resolutions:

all LTAs by this author…

One way of keeping up with new website additions that has been getting a lot of press lately–largely driven by the buzz about blogs–is by subscribing to a given site’s RSS feed, which will automatically and periodically notify you of new content in a so-called “news aggregator” which may be a separate desktop application or a web-based application provided by a third party. The LTA of the Week site is available via RSS.

But most websites do not yet provide RSS feeds to readers, and many never will. How do you monitor those pages? Given that RSS is rather “take it or leave it,” how can you control precisely what changes on a website you are notified of? And how do you monitor website changes convenienty without using yet another solution or having to (re-) open your browser all of the time? This LTA describes a solution–a free easy-to-use, web-based service that enables registered subscribers to monitor text-based changes to selected web pages in a customized and confidential fashion. The generated reports are delivered to the user’s e-mail, and/or appear in a protected area of the WatchThatPage website: “Your Profile.”

ATS Consulting, an Oslo, Norway based consulting firm, launched WatchThatPage.com in November 2001. The site URL is:

Sample Report

The following is an actual report for January 9, 2004. Though the subscriber monitors three web pages of JURIST, the legal news and education portal, the report reveals that only one web page changed:

Web-based Accessibility for Persons with Disabilities

WatchThatPage.com’s web-based accessibility was assessed using the online version of Watchfire Corporation’s Bobby software:


Please refer to http://jade.mcli.dist.maricopa.edu/lta/archives/lta40.php

As of the time of this writing, (01/09/03), the WatchThatPage.com website did not meet the requirements for Bobby approved status for the checkpoints established in Section 508 of the US Rehabilitation Act. Therefore, the WatchThatPage.com website might not be easily navigated by persons who are blind (or otherwise unable to read) and require assistive technology to audibly present web-based text. The WatchThatPage.com website failed to provide alternative text for all images (in 21 instances) and to “explicitly associate form controls and their labels with the LABEL element” (in 2 instances).

Because it is text-based, WatchThatPage.com would likely not alert subscribers to meaningful graphical changes on a website unless these were accompanied by textual descriptions.

More Information Regarding Change Detection Services

The link below is to an article written by Steven Bell of Philadelphia University that is related to a variety of “Change Detection Services” in addition to WatchThatPage which is specifically described in this LTA.



WatchThatPage.com is a unique and useful service that is free, and easy to use for individuals who do not require assistive technology to audibly present web-based text. WatchThatPage.com has numerous potential applications to scholars and researchers, website supervisors, news services, and virtually every industry. One of the tool’s chief strengths is its capacity to “push” customized web-based information to subscribers, in a manner that does not require them to intentionally visit the website.
