How Growth Teams Use Competitor Campaigns to Improve Their Own Performance

Growth teams are typically data-driven and experiment-focused. They run A/B tests, analyse funnel performance, and iterate on creative and copy based on what the numbers tell them. One underutilised data source for growth teams is competitor campaign data — a form of external experimentation that happens in public and provides signals about what resonates with shared audiences.

Reading competitor campaign signals

When a competitor runs the same campaign theme across multiple channels over multiple weeks, they're almost certainly seeing positive performance signals that justify the continued investment. Conversely, a campaign that appears briefly and disappears without amplification has likely underperformed. Watching competitor campaign lifecycle — how long campaigns run, whether they're amplified or scaled back — provides indirect evidence of what's working in your shared market.

Subject line and headline analysis

Email subject lines and paid ad headlines are particularly rich sources of creative intelligence for growth teams. Competitors only repeat what works. When a competitor uses a specific angle, urgency type, or benefit claim repeatedly across their email programme, it's a reasonable inference that this approach is resonating with their audience — an audience that overlaps substantially with yours.

Channel prioritisation signals

When a competitor significantly increases their investment in a specific channel, they've typically done the analysis that justifies that investment. This doesn't mean you should follow — your audience mix, brand positioning, and margin structure may make a different channel more efficient for you. But competitor channel shifts are worth examining as a hypothesis about where growth opportunities exist in your shared market.

Avoiding the imitation trap

The risk of using competitive intelligence for growth decisions is blindly copying what competitors do. Context matters enormously: what works for a competitor with different brand positioning, customer mix, or unit economics may not work for you. Use competitor signals as hypotheses to test, not as templates to implement. The goal is insight, not imitation.
