Sometimes it is interesting to have control over the changes of a website . We may have our own page and we want to monitor that everything works well or we may simply be waiting for a change in a website that we usually visit. In this article we are going to talk about a series of online services with which we can monitor web pages. We may, for example, receive alerts when there is a variation.
Why monitor a website

You may be wondering what these services are actually for and why it might be important to monitor a website for any changes. There are different reasons, as we will see. They range from being informed to being able to solve possible problems as soon as possible.
One of the reasons for wanting to monitor a web page is to be able to detect changes as soon as they occur. For example, if we are waiting for them to publish a certain article or upload some new content, these types of tools will notify us as soon as they detect that change.
It may also not be a new article, but simply something that already exists and is about to receive an update . A new version of a program that is available, a change in a text, etc. We will also be permanently informed of whether it has occurred or not.
On the other hand, if we have a personal page and we want everything to work well, that there is no problem and detect any variation that may exist, we will be able to count on this type of services. All this, in addition, in an automated way so as not to have to constantly open a page.
