How to see a competitor's ads on every platform

Every big ad platform now has a public library. The work is knowing which to search, and in what order.

Short answer

Search each platform's public ad library: Meta's Ad Library, Google's Ads Transparency Center and LinkedIn's Ad Library cover every country; TikTok, Microsoft and Snapchat list ads shown in the EU. Start with Meta and Google, since most companies advertise there. Check the site's pixels to see which platforms it's set up for.

Which ad library do I search for each platform?

Nine platforms have one; three of them cover every country.

Where do I start?

With Meta: in our 13 stored reports, 12 companies ran Meta ads as a main or supporting channel, more than any other platform.

Google Ads came next (7 of 13), then LinkedIn (7, all of them software companies).

How do I know which platforms a competitor advertises on?

Look at the pixels on its homepage: a Meta, TikTok, LinkedIn or Google Ads tag means it's set up to advertise there.

Our free tech stack and pixel checker reads them from any homepage in a few seconds. A pixel without ads in the library usually means retargeting or a paused campaign.

What should I write down from each ad?

The hook, the offer, the format and the start date.

Field	Why it matters
First line or first 3 seconds	The hook they're paying to test
Offer	Free trial, discount, demo: where they push people
Format	UGC video, static, carousel: what they've found works
Start date	Months-old ads are the ones that make money
Landing page	The page they send paid traffic to, and its price

A copyable template for a competitor's ads.

Can I see all of a competitor's ads at once?

Yes: a report reads Meta, Google, LinkedIn, TikTok, Microsoft and Snapchat's libraries in one go and puts each platform's status, ad count and start date in one table.
