Free Chrome Extension to Instantly See Competitor Ad Spend (No Subscription)
See real EU/UK ad spend data on any competitor's website without subscriptions or estimates. The free Brandsearch Chrome Extension overlays spending data directly on Meta Ad Library pages and Shopify stores.
Why Most Competitor Ad Spy Tools Fall Short
Most free ad spy tools show you ad copies and creative elements. They don't show you the budget.
You get screenshots of ads. You see headlines and images. But you're missing the most important signal: how much money competitors are actually spending to acquire customers.
Tools that do claim to show ad spend typically work with estimates. They calculate potential spend based on reach or impressions. Those numbers can be off by 300-500%. An ad showing "estimated $500/day" could actually be spending $150/day or $2,000/day. You can't base budget decisions on guesses.
Subscription requirements create another barrier. You get a 7-day trial, then you need to commit $99/month. For many brands spending $500-2,000/day on ads, that's a manageable cost. But if you're validating a new product or just starting out, you need free access to real data.
The Brandsearch Chrome Extension solves this. It's free. It shows real EU/UK ad spend data directly on competitor pages. No estimates. No subscriptions. You install it once and the data overlays appear automatically.
How the Free Chrome Extension Works
You install the extension from the Chrome Web Store. It adds a small icon to your browser toolbar. When you land on any Shopify store or Meta Ad Library page, you click the icon.
Instantly, you see traffic estimates, active ad counts, and tech stack information. For EU/UK competitors, you see real ad spend numbers — not estimates. The data appears as an overlay directly on the page you're viewing.
If you're looking at a Meta Ad Library page for an EU-based advertiser, the extension shows actual daily spend by country. You might see "FR: €800/day, DE: €1,200/day, NL: €400/day" — real budget numbers Meta doesn't show you.
For worldwide ads outside EU/UK coverage, the extension shows rank movement. An ad climbing from rank 1,000 to rank 40 in a week is getting serious budget pushed into it. Rank movement is the clearest signal of active scaling when direct spend data isn't available.
The extension works on 7.5M+ Shopify stores. It pulls data from Brandsearch Discovery's database of 160M+ ads across Meta, TikTok, and Instagram. You're seeing the same intelligence paid users see, but focused on the specific competitor you're researching.
Stop reading about winners. Find them yourself.
Search 6.5M+ brands, their ads, revenue, and products — all in one place.

Actual ad spend numbers instead of estimates. Other tools show calculated spend based on reach or impressions. The Brandsearch Chrome Extension shows real budget data for EU/UK advertisers. When you see "EUR 3,200/day" on an ad, that's the actual amount being spent — not a guess.
Cross-platform performance context. The extension shows ads from Meta, TikTok, and Instagram in one view. You see which platforms a competitor is active on and where they're allocating budget. A brand might have 200 Meta ads but drive most of their revenue from TikTok organic — you'll see both.
No subscription or credit card required. The extension is completely free. There's no trial period. No usage limits. You install it and the data is there every time you research a competitor.
Active scaling signals. Beyond spend numbers, you see which ads are actually working right now. Ads with 25+ running days that are still climbing in rank are proven winners. The extension highlights these scaling signals so you know which creatives to study first.
One-click activation. You don't need to copy/paste URLs or switch between tabs. The data overlays appear directly on the pages you're already visiting for research.
How to Use Competitor Ad Spend Data to Boost Your ROAS
When you know what competitors are actually spending, you can make smarter budget decisions.
Identify winning ad strategies instantly. Look for ads with 25+ running days and consistent spend. If a competitor is spending EUR 2,000/day on the same video ad for 60 days, that ad is profitable. Study the creative, hook, and offer — it's already been validated with real money.
Adjust your budgets based on real data. If you see three competitors each spending $5,000+/day in your niche, you know the market can support higher ad spend. If you see most ads dying after 3-7 days with low budgets, you know the winning threshold is higher.
Spot emerging trends before saturation. When you notice multiple competitors increasing spend on a new creative angle or product category, you're seeing a trend develop in real time. You can pivot your strategy before the market becomes crowded.
Validate your own tests against proven winners. If your best-performing ad has similar metrics to competitors' scaling ads — similar hook structure, offer angle, visual style — you can confidently increase its budget. You're not guessing anymore.
The Brandsearch Chrome Extension gives you this intelligence for free. You can start using it today without creating an account or entering payment information.
