Outlier Highlighter for Google Ads™

Google Ads shows you numbers. This extension shows you which of them are unusual — right in the table, with no export and without setting thresholds first. **Outliers without configuration** The normal range is derived per column from the data itself (median and robust spread, not the mean). A single extreme value therefore cannot skew the reference or hide itself. No rules to set up, no thresholds to maintain. **Judged the right way round** The extension knows the direction of common metrics in English and German: high cost, a high CPA or a high cost/revenue ratio turn red; many conversions and a high ROAS turn green. Targets such as target ROAS stay unjudged, because they are settings rather than results. **Trends in segmented views** With day, week or month segmentation the extension evaluates the series: trend strength via Theil-Sen regression, significance via the Mann-Kendall test. A sparkline with the total change appears in the column header. Findings are then measured against the trend line instead of the median — so a steadily rising value is not flagged simply for being the highest. **Comparison groups, not a jumble** Expanded daily or weekly rows are measured against their own campaign, not the whole account. Without that, a small campaign's €300 would stand against a large one's €5,000, and half the table lights up. **Data bars and colour scales like Excel** Data bars or a red-yellow-green scale make relative size visible within the comparison group. Switchable, and can be turned off. **The analysis at a glance** Clicking the status badge opens a short summary: the most notable values, detected trends and the largest changes versus the comparison period. Clicking an entry jumps to the cell. **You stay in control** Choose which metrics are evaluated. Set the sensitivity. Turn trends, outliers or the colouring off individually. Interface in English or German. **Privacy** The extension sends nothing. No servers, no analytics, no sharing. It needs exactly one permission (`storage`) and works only on ads.google.com. On billing and payment pages it deliberately does not start at all. --- Google Ads™ is a trademark of Google LLC. This extension is an independent product and is not affiliated with Google LLC.
