How can you monitor content decay (decline in traffic) using Page Explorer?

The Advanced filter in Page Explorer allows you to set specific criteria, such as a percentage drop in organic traffic over a defined period, directly identifying pages experiencing content decay. Checking SERP position history for each page would be time-consuming and less direct for identifying widespread decay, as a position drop doesn't always equate to significant traffic loss. Comparing HTML snapshots between crawls is irrelevant to traffic analysis and content decay. Analyzing keyword difficulty for each content page helps with content strategy but doesn't directly monitor traffic decline.
