Create groups to manage high amount of pages. Easily change settings, pause or resume auto change detections for your groups. Enable or disable groups for update change detections if you only want to check changes for specific groups or websites.
Hide Banners And Ads
We hide cookie banners and ads before we take the screenshots. Cookie banners overlay the content, which might have changed. And ads most likely change with every screenshot. This way we avoid false alarms.
Check Mobile And Desktop
Select for each page the device for your change detection. You can choose between mobile and desktop – and both of course. Make sure your website looks good on the phone too.
Verify Changes After Fixes
After an installing updates and using the update change detection, something on the website might have broken. After reviewing the change detection image and fixing the website, you can take another compare screenshot. We compare it with the screenshot before installing the updates. Now you see if your fixes worked in new change detections.
The Change Image
With every change detection we create a new picture and highlight the changes. You will see at a glance where the differences are. To avoid false alarms,
CSS Before Screenshot
Do you have dynamic content like sliders or related posts, which change dynamically? Hide them for the screenshot via CSS. You can inject any CSS you want before we take the screenshots. This way you can lower false alarms.
Change Detection Link
Every change detection has a public link to the change detection. You can share this link for e.g. with your webdesigner who can see the change detection without login to your WebChangeDetector account. Your designer can check the differences and make fixes on your website.
Alert Email On Changes
When there is a change on a website, the auto change detections sends an alert email to email addresses you can define. It tells you how many percent changed and with one click on the link in the email, you can see the change detection.
