Actively monitoring your website can help you mitigate the risks of a website is not loading properly on specific browsers or devices.
Tracking website changes can also ensure, in some cases, that your website stays compliant with any applicable laws and regulations in your jurisdiction.
But you don't have to simply monitor your own website. Better yet, you should monitor your competitors to see when they change their design, layout, or copy on their sales pages. This information can prove extremely valuable to your marketing department as it can help them position your brand as a better alternative.
We've written an in-depth guide on brand monitoring covering the best ways to keep track of your competitors' online presence, so be sure to read it if you want to learn more about online monitoring.
In this article, I will cover 5 of the best tools you can use to monitor and keep track of website changes, so you can stay on top of problems before they arise.
How to monitor if a website changes?
The best way to monitor if a website changes is by using a tool that can automatically screenshot or crawl the target web page. Some tools can send you a notification when they detect a change, so you can stay on top of everything that might happen on your target webpage.
How to track website changes?
You can keep track of website changes using tools that capture screenshots over a period of time. These tools can create a website screenshot archive you can use to track all pages of interest on any website.
How to check website changes history?
The best way to check website changes history is by using a tool like Wayback Machine or picking between different Wayback Machine alternatives.
Just keep in mind that some tools do not allow you to specify when a page gets archived. You must build a dedicated app or workflow if you want complete control over this process.
