If you reached here by Googling “page change detection” , You may have noticed that there are several more highly ranked services such as changedetection.com and visualping.io. The topic of change detection and notification has been existing since the dawn of web era, so there are many players on the stage. Each of them does something better than others, at least in one dimension.

However, all other services, whether free or not, are trying to use one formula to solve all problems. In those systems you need make inputs following some chilling rules created by the folks who believe #$*? means more than ABCD. You get notifications in a format that is defined even before knowing what you are actually interested in. Such systems may work fine on some sites, but poorly on others. Sometimes user finds himself struggling to make a valid input. Sometimes they get notification but have to make more analysis to understand what is going on. And more frequently, they keep being teased by false alerts. 


Deep-watch provides totally different experience. We precisely deliver what you want, in personalized and comprehensive format. For example, if you want to get notified when the price of some product goes down at Amazon.com, you are likely to get mails like below.

On the other hand, if you are interested in good reviews on the same product, you are likely to get mails like below.

The point is, we extract core information from web pages and deliver it in itemized style. The core information will be exactly what you wanted, no more, and no less.
 

Above examples are actually part of deep-watch’s public offer. Besides, we also provide private offers, where you can have more personalized notifications.

You just need fill out a simple form to submit a request for private task. In the form you can describe request in natural languages, just as if talking to operators in calling center. There are no rules on your input. It works as long as it is readable by human being.
 

The secret is, we have talented engineers handling your requests at the service desk. As soon as you submit a request, they will do the following work in timely manner.

  1. Read your request and understand what you want.
  2. Analyze target page and find the best approach to retrieve what you want.
  3. Set up a crawler and put it online.

With those 3 steps done you will get an email saying service is ready.
 
All above seems to be heavy work, but our engineers can finish it within a few minutes because they are skilled programmers, and supported by a smart system that can retrieve information from web pages with high efficiency.
 

So here comes the conclusion, deep-watch is smart because our engineers are smart. With such high level intelligence, we provide smarter service that is never matchable by mechanical handlers.

  • It can be insensitive on embedded ads, like-button counters, small layout changes and occasional page errors, so you are always free of false alerts.
  • It is self-adaptive to large design changes, so you don’t have to re-setup even if target page changed its design.
  • It can retrieve data from pages that are not directly accessible by URLs. This is usually essential to monitor interactive web pages (e.g. query on ticket availability).
  • There are even more here.

 
So what you need to do is to go to New task page, paste the URL that you want to monitor, describe the conditions that you want to get alerted, and leave an email address to receive alert mail. Soon enough you will get an email asking for mail address validation, just click the link enclosed in the email, then you can go for a coffee break. If our request queue is not in congestion, you are likely to get the “service ready” mail before the coffee is ready.
