Proxies for Monitoring Websites


Website change monitoring works by sending continuous GET requests to the target website. This means that the target receives many requests very quickly. Sending such requests from a single IP address will get it blocked in no time. To avoid that, monitoring tools have to use proxies. 


Some monitoring tools allow integrating your own proxy list. This is a helpful feature because you can get proxies from your preferred provider and ensure the most efficient monitoring. 


Depending on your needs and the use case, you may want to use residential proxies for tracking website changes. These proxies are more reliable than other types of IPs because they’re harder to detect. They can also cover any location in the world with precise geo-targeting, so you can see how your website appears in different areas around the world.




Website changes matter because they can inform you about security breaches, changes on the competitor’s websites, and new offers. Various businesses track their own and competitor’s websites to gather valuable information that is later used for improving the user experience on the website or gets integrated into a business strategy.

Get residential or mobile proxies for just $2.

The tools for change detection can easily extract information that you wish to get and instantly inform you about changes on various websites. You can set alerts on security issues, new job openings, price changes, and new offers. These notifications may arrive wherever you want them - via a mobile app, email, or social media.


Proxies are an integral part of every change detection tool. Without them, monitoring wouldn’t be possible because IPs would get blocked with every request. Choosing a reliable proxy provider is an important step in the website monitoring process.
