If a competitor quietly rewrites their ad copy, launches a new promotion, or starts bidding on your brand keyword, you probably won’t notice until you happen to search for one of your own keywords at the right moment. That’s a reactive approach, and it leaves gaps.
Tracking competitor Google Ads changes over time requires a structured system: something that captures what competitors are running today, stores that data, and alerts you when something shifts.

Meaningful changes worth tracking include:
- Headline rewrites that change the core value proposition (moving from
