Frequently asked questions

What is a YouTube ad spy tool?

A YouTube ad spy tool lets you search and analyze video ads competitors are running on YouTube, including estimated spend, views, duplicates and country targeting, so you can model what's working instead of guessing.

Is there an official YouTube ad library?

Not a dedicated one. Google's Ads Transparency Center covers YouTube ads, but it's not YouTube-specific. You can only look up one advertiser at a time and it shows no performance data: no spend estimates, no view counts, no longevity signals. VidSniff is built specifically for YouTube, giving you a searchable database across all advertisers with the performance data the Transparency Center doesn't show.

How does this differ from the official Google Ads Transparency Center?

Google's Ads Transparency Center only lets you look up one advertiser at a time and shows almost no performance data: no spend, no views, no longevity. VidSniff is a searchable, filterable index across the whole YouTube ad network with estimated spend, views, duplicates and country targeting on every creative.

Why would someone need a YouTube ad spy tool?

Because guessing what works on YouTube is expensive. A spy tool shows you which hooks, formats and offers competitors are pouring real budget behind, so you can model proven winners, skip the losing tests, and ship better creative faster.

Can I find landing pages and video URLs?

Yes. Every ad in the index exposes both the original YouTube video URL and the landing page (destination URL) the advertiser is sending traffic to, so you can study the full funnel, not just the creative.

How much does VidSniff cost?

VidSniff Pro is $39/month or $29/month billed yearly. Every plan starts with a 3-day free trial. Cancel anytime.

How many YouTube ads are in the index?

Hundreds of thousands of YouTube video ads, refreshed weekly. New creatives are added continuously from advertisers spending across 50+ countries.

Who is YouTube ads intelligence for?

Performance marketers, ecommerce and DTC brands, growth teams, agencies, media buyers and creative strategists, anyone who needs to know what's actually winning on YouTube before they spend their own budget.

Can I see which countries an ad is running in?

Yes. Every ad shows the countries where it has been observed serving, with flag badges and a country breakdown. You can filter the whole library by country.

Do you offer a free trial?

Yes - every plan starts with a 3-day free trial. You can explore the dashboard, run searches and save ads to your library before paying anything.

Stop guessing. Start sniffing.

Open the dashboard and find your next winning YouTube ad in under 60 seconds.
