Various advancements in the IT sector have provided solutions for a majority of problems of the present business landscape. Yet, it has always been difficult to track all the real time changes of a live website that is available on the internet. To aid this purpose, various online change monitoring tools have come into existence. These tools provide a host of features to satisfy various use cases related to web content change monitoring as discussed in this article below.
To begin with, any kind of content monitoring service will always be facilitated by a server and client based architecture. The change monitoring server will at first send a request to the website to be crawled. Then content crawling takes place, which will then be followed by comparing the current content with the previously crawled content version. For this, the client must install a plug-in on the browser and then add pages to the plug-in. The plug-in will then visit the particular webpage, compare the content, and notify the user about the recently made changes.
The need for an automated tool:
Hence it is always recommended to make a list of all websites that needs to be tracked in the change monitoring software. Once done, it will be really easy to track changes without actually visiting the target website or availing a mail subscription or by consuming their RSS feeds or by frequently following their social media profiles. Now you may think, what is the need to opt for a change monitoring service when it is possible to manually track the website content changes through all the previously mentioned methods? Well, it will only work when you have a lot of time in your hand and left with only a very few numbers of websites to keep tabs on.
Let us assume that you are planning to track more than a dozen of websites. In such a scenario, you may be in a position to visit them as frequently as once every 5 minutes or several times an hour or on a daily/weekly/monthly basis. Tracking all changes in the website content for such many websites would be extremely time-consuming and challenging as time progresses on. Further, your job will become a lot more difficult if new content gets added to the websites that are available on your watch-list too!.
Detect website changes of the dynamic nature of websites:
Identifying change volume and changing the process of webpages has been of great interest to the analyst. The content of webpages and their change frequencies have been highly focused areas in competitive research.
Table below presents a summary of the various research work carried out to detect the dynamic nature of web content. It can be seen that webpages belonging to popular websites such as sports and news websites tend to change frequently whereas webpages belonging to government and educational domains change less frequently. Hence, it can be concluded that webpages belonging to popular websites tend to change more frequently than those of less popular websites that target specific functions and niche audiences.
