If you need to monitor a web page for changes, try Visualping, and an automatic email will alert you as soon as small or large changes are detected!
Visualping is an online tool that allows users to monitor changes in pages and websites and receive automatic alerts as soon as one is detected. To use Visualping, you just need to paste the link to the site, select the area and type of change to be monitored (text/visual/element) and how frequently, the extent of the changes (small, large, huge), and the email address on which to receive the alert. You can use Visualping to receive information about discounts, posts on social media, sales openings, and much more before everyone else.
You can use Visualping for free to monitor up to 5 pages on a daily basis. If you need something more, the price will increase based on the number of pages you need to keep an eye on and the frequency of the checks.
