A Chrome extension that shows a competitor's live Google Ads automatically as you browse their site.
Grounded in available product and source data
Checking what ads a competitor is running usually means digging through an ad-transparency tool or guessing from screenshots someone shared — Competitor Ad Tracker is built to skip that step by surfacing a competitor's active ads automatically the moment you land on their site.
Detection currently covers Google Ads specifically. The developer states Meta ads and additional platforms are planned, which means for now the extension only catches what a competitor is running through Google's ad network, not Facebook, Instagram, or other channels. No registration or setup is required — the extension works passively as you browse rather than needing a domain entered into a search box first.
What the listing doesn't detail is how much depth sits behind each spotted ad: whether it shows the ad copy alone, the landing page it links to, an estimate of ad spend, or history across different creative variations a competitor has tested. The listing states a privacy-first approach with no personal data collection, though specific browser permissions requested aren't broken out on the page.
For a marketer specifically watching Google Ads activity from a short list of known competitors, checking their sites directly with this running is a faster loop than a separate lookup tool. Anyone who also needs visibility into a competitor's Meta or other ad-platform activity will need a different tool until Adsby ships that coverage.
Not yet — the developer states coverage currently spans Google Ads only, with Meta ads and additional platforms described as planned for the future rather than available now.
No — the extension works automatically as you browse to a competitor's site directly, rather than requiring you to search for or enter a domain into a lookup tool first.
The listing doesn't specify beyond showing that an ad is currently running — details like the landing page it links to, estimated spend, or a history of past creative variations aren't described as part of what's displayed.
No — the listing states no registration is needed; the extension detects and displays ads automatically once installed.
