What is Reveal Ad Spend?
Reveal Ad Spend is a free Chrome extension that surfaces the EU reach figures Meta publishes for ads in the Meta Ad Library. Under the Digital Services Act, Meta must disclose how many people in the EU saw each ad, but that number normally sits buried inside each ad's details, one ad at a time. Reveal Ad Spend pulls it out and puts it directly on every ad card, then turns it into an estimated spend figure using a formula you control.
Who it's for
- Competitive researchers — who want to see which competitor ads reached the widest EU audiences without opening each ad manually.
- Media buyers and strategists — who need a rough spend benchmark for ads running in European markets.
- Coaches, consultants and B2B marketers — who want a fast, free read on ad activity before committing to a paid intelligence tool.
Key features
Sort by EU reach
One click ranks every ad on the results page from widest to smallest EU reach, grouped ads included. It replaces manual parsing and spreadsheet work with an instant view of top performers.
Estimated spend calculation
Enter your own CPM and frequency, and the extension applies the formula (Reach ÷ 1,000) × CPM × Frequency to every ad on the page. Because you supply the inputs, the estimate stays transparent rather than a black box.
One-click PDF ad reports
Each analyzed ad gets a printable report containing the creative, ad copy, headline, page name, EU reach, estimated spend, and — when Meta provides it — the EU audience split by age, gender and location. Reports open in a new tab and are ready to save, share, or upload to an AI tool that accepts PDFs.
Pause and resume analysis
You can stop an analysis partway through and keep whatever has already been collected. That makes it practical to work through large result pages in stages.
What stands out
Reveal Ad Spend turns a legally mandated transparency number into a working spend estimate — with a formula you set yourself.
The extension doesn't hide its assumptions: CPM and frequency are yours to define, so the output is an estimate you can reason about rather than a mystery figure. Reach data only exists for ads delivered in the EU, which keeps expectations honest. And the whole workflow — reach, sorting, estimation, reporting — happens inside the Ad Library page you're already using, with data staying in your browser.
Worth checking out if…
You research Meta ads aimed at European audiences and want reach and spend signals without paying for a full ads-intelligence platform. It's also a good fit if you already have a CPM benchmark in mind — Pantheon publishes a free CSV of CPM estimates by EU country and niche if you don't. Just go in knowing that spend is always an estimate, and that ads without EU delivery won't show reach at all.
