Highlight high frequency
Marks frequency-column cells above a threshold so you spot ads at risk of audience fatigue in time.
Code to copy
(function () {
var MAX_FREQ = 3; // flag ads above this frequency
function scan() {
try {
var cells = document.querySelectorAll('[role="gridcell"],[role="cell"]');
cells.forEach(function (c) {
var lbl = (c.getAttribute('aria-label') || '');
if (!/frequency/i.test(lbl)) return;
var m = (c.textContent || '').match(/([\d.,]+)/);
if (!m) return;
var n = parseFloat(m[1].replace(/,/g, ''));
if (isNaN(n)) return;
c.style.background = n > MAX_FREQ ? 'rgba(245,124,0,0.25)' : '';
c.style.fontWeight = n > MAX_FREQ ? '700' : '';
});
} catch (e) {}
}
scan();
setInterval(scan, 2500);
