Mask and exclude DOM elements
Whenever you have highly dynamic elements on your pages you will soon notice that they give you false positives regularly. For example, you've added the Disqus widget or you have a slider or a video that autoplays.
For this, we have developed capabilities of masking (filling a region with green color) or excluding (completely removing from DOM) elements. You can find these settings under Modify section of the project's settings.
Check the block in the sidebar with a graph.
You will need to use CSS selectors (same as jQuery uses) to let the system know what elements to mask or exclude.
Good practices to mask would be elements like sliders, auto-played videos, ads.
Good examples of excluding could be different popups (like cookies policy), live chats, and any other elements that won't break the layout if you remove them.
