Highlight high CPC cells in Google Ads
Highlights cost-per-click cells above a set threshold so expensive items stand out quickly.
Code to copy
/* Highlight cells with a high average CPC (above a threshold) */
(function () {
var THRESHOLD = 5; /* edit: currency units */
function scan() {
try {
var cells = document.querySelectorAll('td, [role="gridcell"]');
cells.forEach(function (c) {
var raw = (c.textContent || '').replace(/[^0-9.,]/g, '').replace(/,/g, '');
if (!raw) return;
var n = parseFloat(raw);
if (!isNaN(n) && n >= THRESHOLD && /[$€£zł]/.test(c.textContent)) {
c.style.background = 'rgba(217,95,14,0.18)';
c.style.fontWeight = '700';
}
});
} catch (e) {}
}
scan();
new MutationObserver(scan).observe(document.body, { childList: true, subtree: true });
