LinkedIn Ad Library: How to Search It (and What It Will Not Show)

What the LinkedIn Ad Library is

LinkedIn launched its Ad Library so anyone can see the ads a company is running, without an account and without being targeted by them. It covers ads that have run on LinkedIn over roughly the past year, across every Company Page, and it is free and public.

For B2B specifically, this is a bigger deal than the Meta library is for D2C. LinkedIn is where most B2B demand-gen creative lives, and until the library existed the only way to see a competitor’s ads was to be in their target audience and wait to get served. Now you can pull a rival’s entire recent rotation on demand.

How to search the LinkedIn Ad Library

You can search two ways, and they answer different questions. Searching by advertiser (a specific Company Page) returns that company’s full recent set of ads, which is the view that matters when you already know who you are researching. Searching by keyword surfaces advertisers using a phrase, which is how you discover competitors you did not know were running ads.

Set the country filter before you read anything. A global B2B brand runs different messaging by region, and an unfiltered view blends campaigns that were never meant to sit side by side.

• Search a Company Page name for that advertiser’s full recent rotation.
• Search a keyword or topic to find advertisers in a category.
• Filter by country, because B2B messaging diverges hard by market.
• Open a single ad to see its format, copy, and the date range it ran.

The EU data most people miss

Ads that target the European Union carry extra disclosure under EU transparency rules: additional information about targeting parameters and audience reach that is not shown for other markets. If you are researching a competitor that advertises into the EU, that view tells you more about how they segment than any other free source.

What the LinkedIn Ad Library will not do

Nearly every frustration with the tool is a mismatch of expectations, so it is worth being clear about the limits.

• It will not show commercial spend. Budget is disclosed only for EU political and issue ads, not for a normal B2B campaign.
• It will not let you save or bookmark anything. Close the tab and the research is gone.
• It will not export. There is no CSV, no bulk download, no way to hand a designer a set of references except by screenshotting one ad at a time.
• It will not organise. No tags, no folders, no way to group by message so patterns become visible.

A 15-minute LinkedIn competitor ad review

The LinkedIn Ad Library pays off without a big research project. Once a month, run this short routine on your three closest competitors.

• Search each competitor's Company Page and note how many ads they're running now compared with last month.
• Sort what you see by format: single image, document ad, video, carousel or thought leader ad.
• Write down the offer behind each ad, such as a demo, a free tool, a report or an event. The offer tells you where they are in their funnel.
• Copy the opening line of every ad into one document. After a few months you'll see which angles they keep and which they drop.
• File the strongest ads by mechanism in your swipe file, and test the angle you think they're under-using.

LinkedIn ad library vs the Meta Ad Library

The LinkedIn Ad Library is smaller and B2B-only, which makes it easier to read. Meta's library covers almost every consumer brand. LinkedIn's shows the companies selling to professionals. LinkedIn also groups ads under the Company Page, so one search pulls a competitor's full recent set, whereas on Meta a brand can run ads from several pages. If you sell to businesses, start with LinkedIn. If your buyers are consumers, the Meta Ads Library will tell you more.

How to actually keep the ads you find

This is the same gap every ad library shares: superb at showing you ads, nothing at all for keeping them. The fix is to file the ads worth keeping by mechanism (the demo-led ad, the customer-logo wall, the founder POV, the problem-agitation open) rather than by brand. Filing by brand produces a folder of competitors. Filing by mechanism produces a swipe file you can actually brief from.

Our ad teardowns break down single ads hook by hook, and the swipe file is real ads with the mechanism written out. Once you spot a mechanism worth testing, the free AI hook generator turns the angle into a batch of openers.
