When a brand doubles their Meta budget in a week, they're not just running an ad. They're broadcasting their intentions to anyone paying attention. Almost nobody is.
Ad spend data is free, public, and updated in real time. It's also one of the most reliable leading indicators of an active campaign window, a period when brands need creative production, strategy, and content at scale.
The Meta Ad Library is public
Facebook built the Ad Library for transparency. Creatives use it for prospecting. Every active ad on Meta is visible: the creative, the approximate spend level, how long it's been running, and which countries it's targeting.
A brand that goes from 0 to 50+ active ads in a 30-day window is in campaign mode. They need video, photography, copy, and strategy, often more than their in-house team can handle. The question is whether you're in that conversation.
What an active campaign window looks like
- 30+ ads running simultaneously, beyond what a small in-house team typically manages alone
- New creative variations launching week-on-week, they're testing, which means they have budget to test
- Mix of static and video ads, multi-format campaigns require more production resource
- Product ads alongside brand ads, full-funnel activity signals serious budget, not a one-off boost
- International targeting when they previously ran UK-only, expansion phase, creative localisation often outsourced
Google Ads Transparency Centre
Google's Transparency Centre is less granular than Meta but useful for spotting brands investing heavily in search. If a brand is spending on broad brand keywords and generic category terms, they're in growth mode, not just defensive retention. That combination suggests campaign budget, not just maintenance spend.
TikTok Creative Centre
The TikTok Creative Centre shows top-performing ads by category and region. Filter to your sector, identify which brands are actively producing TikTok-native content, and cross-reference with their other spend signals. A brand testing TikTok for the first time is almost always looking for external creative help, TikTok native content is a skill set most brand teams don't have in-house.
The double signal
The most reliable indicator isn't a single data point, it's a cluster. A brand increasing ad spend and hiring creative roles in the same window is sending the clearest possible signal: they're scaling simultaneously in-house and out. That's when the external creative opportunity is largest and the window is shortest.
Why this beats cold outreach
Cold outreach is context-free. You're asking for attention from someone who doesn't know you, about a problem you've assumed they have. Signal-led outreach starts with an observable fact about what they're doing right now. It's specific, it's timely, and it demonstrates that you've done your homework. The reply rate difference is not marginal, it's transformational.
