Highlight high cost per result

Scans the cost-per-result column and tints cells above a threshold red; change the limit on the first code line.

Code to copy

(function () {
  var LIMIT = 50; // alert threshold for cost per result
  function scan() {
    try {
      var cells = document.querySelectorAll('[role="gridcell"],[role="cell"]');
      cells.forEach(function (c) {
        var t = (c.textContent || '').trim();
        var m = t.match(/^[^\d-]?\s*([\d.,]+)/);
        if (!m) return;
        var n = parseFloat(m[1].replace(/[, ]/g, ''));
        if (!isNaN(n) && /cost per|cpa|cpr/i.test(c.getAttribute('aria-label') || '')) {
          c.style.background = n > LIMIT ? 'rgba(211,47,47,0.22)' : '';
        }
      });
    } catch (e) {}
  }
  scan();
  setInterval(scan, 2500);
})();
